TEST: LD Systems Maui 44

Do you know that? The sprinter drives up, the first, still comparatively small sound element is unloaded and from the back right corner you can hear “Oh God, I hope it won’t be too loud”. The normal company party-goer's fear of the sound pressure is almost palpable around 3 p.m. in the afternoon. The same tie-wearer who kneels like a bucket on the dance floor around 12 o'clock in the evening to play air guitar can't be loud enough during the final "Smoke On The Water", even though, according to the neighbor across the street, " Motörhead at Wacken” volumes approached.

So what do you need to make your customer happy? A small P.A. that is as small as possible and as good-looking as possible, which, despite its discreet appearance, can, in case of doubt, pack a hefty pound in the kilowatt range without running the risk of sending the built-in loudspeakers to direct current death. With the LD Systems MAUI 44, there is now a column principle on the market that is equally impressive in both the optical and acoustic areas. Get the pound!


construction

The first impression of the system developed and built in Germany is excellent in several respects. On the one hand, the system consists of three comparatively small elements, which can be connected to form an impressive column in a minimum of time using a plug-and-play connection. Perfectly milled guide slots and the matching steel pins ensure a firm hold, with the signal flow guaranteed via centrally installed plug connections. Tangled cables are a thing of the past. For easy handling in stacking operation, carrying handles are mounted on the back of the columns. When operating indoors, however, it is important to ensure that at least a clear ceiling height of approx. 2.50 meters is required in order to be able to combine the system's plug connection. Party room, basement, approx. 2.20 meter ceiling height? Get out of the mouse!

The actual system consists of a subwoofer and 2 column satellites with different loudspeakers, offering an RMS power of 1600 watts with a peak of 3200 watts at a maximum SPL of 129 dB. As almost always, Class D power amplifiers are used here, without which such power outputs of this magnitude would not be possible. For the bass range, there are 2 12" neodymium speakers with a load of 800 watts, while the column elements with a total of 16 3.5" midrange drivers and 2 1" tweeter drivers also provide 4x 200 watts.

When it comes to portability, the system sets real standards. In terms of weight, the upper column with 10.2 kilograms and the middle column with 7.4 kilograms can easily be moved by a single person, while the subwoofer, despite the light magnets, due to its solid construction in 15 mm birch multiplex and the management of the control electronics with its 40.8 kilograms likes to take up the work of two strong men's arms. Fortunately, the transporter has the ergonomic LD Systems Evolution carrying handles at his disposal, which enable bold gripping from all angles.

In terms of dimensions, it is also very compact. Subwoofer (620 mm x 412 mm x 615 mm), satellites, upper column (120 mm x 973 mm x 144 mm) and satellites, lower column: (120 mm x 838 mm x 144 mm) can be easily stored in the trunk of a small car , mind you, without any wiring. However, it is important that you don't forget the very well locked but still rare Speakon power cable; you can't get any further with the LD Systems MAUI 44 with the classic cold device plug. For ultimate transport convenience, you can purchase a separate roller board, which can be connected directly to the subwoofer using butterfly fasteners. All elements are protected from external influences with solid, black steel grilles.

The entire connection area is built into the subwoofer so that the notorious, unsightly cable bulges don't hang down from the satellites. A treat for the eyes! In the input area we have two combination sockets (XLR/TRS) and two cinch sockets available, with which any signal can be processed. If you want to connect several systems in series using the daisy chain method, 2 XLR outputs are available. If you want it to wobble even more under 40 Hertz, the system also has a separate woofer XLR output.

Two separate volume controls can be used to control the overall volume and the subwoofer portion. This is very helpful for giving your sound a personal touch or for adapting the bass component to the signal present. Four small LEDs provide information about the most important operating states, such as power, peak, applied signal and the use of the internally installed limiter.



Practice

If your own wife comes into the test room and speaks favorably about the appearance of a sound system, the designers must have done more than just good work! In fact, in the right light, the system would even pass as a designer element within a modern residential complex. However, anyone who now believes that LD Systems has neglected the efficiency or even the sound orientation of the system in favor of the optics is very much mistaken.

The first listening impression is very powerful with excellent radiation characteristics. The unpleasant beam of some other systems is reduced to a minimum by the loudspeakers and illuminates both a room and an open-air area acoustically very well. It is noticeable that both the close and more distant listening areas receive sound almost equally well. Personally, I find the separately adjustable bass component to be a great help, depending on the signal present or the room acoustics, to give the basic sound more boost or to protect it from dangerous booming components.

However, due to the massive number of midrange drivers, the LD Systems MAUI 44 has its own sound coloring, which cannot be viewed in a judgmental way. As expected, the mid/high-mid range is extremely present, which makes the highs look a bit “discreet” in direct comparison with a linear filter setting. Here I would possibly add a touch of “shine” with a sum filter. The infamous low-mid hole in the crossover area to the subwoofer can only be heard very discreetly with this design and can easily be concealed if necessary.

In terms of application, the system is absolutely convincing both as a hall sound system and in sidefill operation. Thanks to its beam angle of 120 degrees, you can also reach areas that are otherwise no longer acoustically illuminated by comparable systems. The processor of the amplifier system also has a coordinated system of equalizer, compressor and limiter in order to create the densest possible sound image from the connected power amplifier, which it also succeeds in impressively.



Conclusion

The LD Systems MAUI 44 is an absolute top P.A. the compact class on the market. I have never come across a system that combines excellent sound values with an exquisite appearance and at the same time sophisticated detailed solutions in this form. Once again, German engineering shows that the “Made-In-Germany” trademark is more than just a geographical indication. The countries in the world where you can find such quality combined with a trained eye for detail can be counted on one hand.

Whether a band, solo entertainer or DJ, if you want an ultra-compact, very good-sounding and excellent-looking small P.A. If you're looking for something, you should definitely take a look at the LD System MAUI 44.

Absolute purchase recommendation!

TEST: LD Systems WS 1000 HHD2

 In view of the fact that radio microphones have long since established themselves as a standard on the stages of the West, as in all areas of the consumer sector, it was only a matter of time before relevant companies turned the price screw by manufacturing in low-wage countries into areas that are almost considered science Fiction can be dismissed.

While the world market leaders such as Sennheiser and AKG will not go below the ominous price range of around 600 euros for a handheld/receiver combination, there are various competitors who have set themselves the target of the up-and-coming young band with the hard-pressed “small wallet”. To ensure wireless freedom on stages.

The manufacturer LD Systems offers its WS 1000 HHD2 double microphone set for a street price of just under 460 euros, a price at which the competition doesn't even start with a single microphone. Let's see to what extent LD Systems can assert itself against its mostly European competitors with its product from Chinese factories.

In terms of sales, the product continues to be sold through the company Adam Hall GmbH, which some of the readers may still know from their busy activity with flight case accessories.





construction

The package includes two handheld transmitters WS1000MD, a WS1000 double receiver, two antennas, two antenna extensions for rack operation, a power supply for the receiver unit, a set of 19 inch rack brackets, four batteries for the transmitters and an operating manual. The receiver unit can also be operated in stand-alone mode without a rack bracket and has four small but non-slip feet on the underside of the housing. The housing is made of sufficiently strong sheet steel and is flawlessly processed.

In terms of transport, the entire system is delivered in a sturdy plastic hard case, equipped with foam to secure the components. The case can even be secured with two locks against unintentional opening thanks to two holes on the sliding locks. However, you can see that LD Systems uses standardized foam milling (one size fits all), so some components such as the receiver unit fit precisely into the recess, while the power supply unit has to be tightly squeezed into the foam at its height. A disadvantage of mass production.


For signal transmission, the WS 1000 HHD2 works with 160 switchable frequencies in the UHF band in the 790,850 - 813,800 MHz range. The receiver is designed in two identical versions with regard to the two reception modules; functions such as the antenna display or displays such as the output level are designed twice. The two displays on the front are equipped with sufficiently large letters and numbers and ensure that the individual information is easy to read even from a distance. The final elements are the power switch on the left side of the front panel and an adjustable headphone output on the right side.

On the back of the housing, in addition to the two antenna connections, there is a balanced XLR output per channel. If the situation requires it, you can also connect both channels to a single output; a balanced XLR and an unbalanced jack output are also available for this purpose. The threshold of the mute level can be readjusted in the event of any interference signals using two recessed trimming screws. The receiver comes with a 12 volt power supply, but the system also accepts voltages up to 18 volts as long as they deliver 500mA of current.

In order to generate a clear assignment of frequencies when using multiple systems, the receiving part in the middle of the front panel has an infrared sensor, which is programmed via the respective transmitter. Using an additional WS100AD Antenna Distributor, 4 receiving units can be connected together to share just one pair of antennas.

The handhelds, which are visually reminiscent of Shure microphones, have a small display on which, in addition to the channel indicators, the battery and infrared indicators also show their status. The product is powered by two standard AA batteries. The gain can also be readjusted using a small trim potentiometer. Unfortunately, the slider is very smooth and cannot be locked, so there is a latent risk of unintentionally deactivating the microphone.



Practice

After activating the products, the transmitter and receiver can be found within a few seconds, as the integrated frequency scanner automatically searches for a free frequency to transmit the signal. This makes handling easier when operating multiple systems in parallel. The subsequent transmission test did not disappoint either. Even a distance at which the signal had to overcome two reinforced concrete ceilings of a 1960s house (lots of steel - lots of shielding!) did not result in any loss of signal.

In terms of sound, the microphone also tries to emulate its visual model acoustically, although it doesn't quite achieve the balance of the original. All in all, the product leaves a good impression, especially since a high-quality filter on the console can help suit your personal taste. As is so often the case, however, when it comes to prices in Asian production, it is difficult to find a real point of criticism here, as the dumping sales price would put even moderately serious shortcomings into perspective.

In terms of weight, the handhelds are in the middle range. An experienced singer will have no problems with the product, although a two-hour performance with a lot of use of the arm should not be underestimated. The advantage of using AA batteries is that, due to the omnipresent use of the energy dispenser, replacement batteries can be found in every supermarket if necessary, which is not necessarily the case with 9 volt blocks.




Conclusion

With the WS 1000 HHD2, LD Systems is bringing a product onto the market that has a good price/performance ratio and, with two handhelds, is entering a market segment that has so far been rather rudimentary. Both radio links work perfectly and have a high level of clarity and good workmanship.

In terms of sound, the product is convincing, even if it lacks the ultimate polish for the top league. However, in view of the sales price, this area is put into perspective again. If you are looking for two radio links in just one housing, you should give the WS 1000 HHD2 a try.

TEST: Lake People MC 100

 The Lake People company from Konstanz on Lake Constance has enjoyed a very good reputation as one of the leading manufacturers of headphone amplifiers for many years. The integration of the regional value chain plus a consistent “Made in Germany” also ensures a good feeling when it comes to job security. Like any successful company, Lake People do not rest on the laurels they have already achieved, but are always striving to expand their portfolio. The manufacturer recently scored points with the microphone preamp category and now with the introduction of two monitor controllers. We have the “smaller” version of the two monitor controllers, the Lake People MC 100, for testing, which, unlike the €500 more expensive MC 100 Pro, does not have a 256-fold relay volume control. All other elements of the two variants are identical.

The construction of the Lake People MC 100

Anyone who takes just a quick look at the product in combination with the retail price of €1,799 will immediately see which customer group the Lake People MC 100 was designed for. The possibility of five different input sources in combination with 3 different monitor systems plus a separate subwoofer output shows that this is a real pro device.

The massive housing with dimensions (W x H x D) 290 mm x 90 mm x 254 mm and a weight of 3.4 kg is perfectly crafted and leaves a very durable impression. Interestingly, Lake People cannot deny its connection to the hi-fi sector, as the Lake People MC 100 rests on four feet, which are also often used in the same segment. Unfortunately, the Lake People MC 100 only has an external power supply, which brings with it the usual problem of placement. To be honest, I would have liked a power socket in this price range.

Except for the 3.5 mm stereo jack input, which is located on the front of the housing and will probably be used primarily in mobile devices, all other inputs are located on the back of the housing. Two XLR stereo pairs labeled IN1/IN2, as well as the unbalanced stereo inputs IN3, which is available as an RCA pair on the back, form the analog input section of the controller, with the two unbalanced inputs switching from -10 dBV to + 4 dBu let. A USB-C socket is used as the digital input, with the internal D/A converter allowing a resolution of up to 384 kHz / 32 bit (PCM) and DSD 256.

In the output area, the Lake People MC 100 uses three balanced stereo outputs plus an additional sub out, all of which are in XLR. A three-stage switch can be used to switch the output signal between 0, -6 and -12 dB. In addition, the Lake People MC 100 has two stereo outputs called Slave Out 1 and Slave Out 2, which allow the connection of additional peripherals in the form of, for example, analyzers or external headphone amplifiers, which can be operated independently of the output volume.

When it comes to headphone operation, Lake People has opened up to a new segment, the so-called crossfeed technology, which has been used for many years in SPL's top products. The effect is a more natural reproduction when using headphones, as occurs when using monitors due to the inclusion of the runtime differences. In addition to a separate headphone volume control, Lake People has installed a continuous X-Feed control with which the effect can be mixed continuously. The Lake People MC 100 offers a 3.5 mm and 6.35 mm stereo jack output, which can also be used at the same time if necessary. Both headphone operation and the crossfeed function can be switched using a pressure switch.

If you want to use several pairs of speakers at the same time, for example to send the signal in parallel to another room, this is also no problem. You simply hold down an output pressure switch while you switch on the desired second pair. This configuration is saved even after the device is switched off. In addition, the Lake People MC 100 has one of the most important functions of a monitor controller, such as solo switching of the respective L/R channels, an L/R swap, a phase reversal of the left channel, a mute function for the rear outputs, a DIM switch of -20 dB and a mono switch. All functions are displayed in their status with their own LED.

All controls and switches on the Lake People MC 100 are of the highest quality and should ensure a long service life. The visual concept is coherent and the feel is high quality. A 41-position Alps RK27 was used as the master volume control, which, as expected, attracts attention with a diameter of 5 cm. The controller runs smoothly and immediately conveys a high-quality feeling, which is what you would expect in this price range.

The Lake People MC 100 in practice

When you set up the Lake People MC 100 in your studio for the first time, the product immediately exudes a certain “grandeur”. Due to the weight in combination with the high-quality rubber feet, the product does not move if you accidentally push the device or if you boldly press the buttons. The practical test was carried out using Eve Audio SC408, Eve Audio SC204 with subwoofer TS 107 and two Fame near-field monitors. All cabling was done using Cordial cables.

The readability of the individual settings is a point that is very important to me personally in the studio. Either you're fighting against atmospheric, but occasionally dim lighting or, as in my case, with some direct sunlight in the studio due to the beautiful, large south-facing windows. The status LEDs on the pressure switches are extremely helpful here, as they directly and immediately display the switching status. The white markings and fonts on the black front panel also do their job very well and offer good legibility even in poor lighting conditions.

When it comes to sound characteristics, the Lake People MC 100 meets the highest demands in every respect. The signal is never colored, always remains transparent and is completely free of all kinds of background noise, such as switching noises or mains hum. Even at high level settings, the Lake People MC 100 does not create noise and remains absolutely noise-free over the entire control range.

As expected, the headphone amplifier area, Lake People's flagship discipline, also offers absolute top values. The amplifier has a very high headroom, so that there was never any saturation or even distortion, even at high volumes. The headphone area should in fact be seen as a separate, additional bonus area and in no way a bonus to a monitor controller. This fact also puts the ambitious retail price into perspective, as in addition to the controller section you also get a professional headphone amplifier.

Of course, I was also excited about the crossfeed function, as an SPL Phonitor Mini has been in use in my studio for years and has already served me very well with the internal matrix. In fact, Lake People starts at the same point in signal processing, although the effect is a little more subtle, but without any tonal changes. The extent to which one appreciates or condemns the unnatural reproduction of the extreme stereo setup of a headphone is up to each user, but with the crossfeed function you have an unpretentious option to shift the listening experience in the direction of monitor reproduction in just a few simple steps. This applies to both the professional and consumer sectors, where you can use the Lake People MC 100 as a high-end headphone amplifier and shift your listening experience more towards a concert hall.

Conclusion

With the Lake People MC 100, the German company has a monitor controller that is outstanding in every respect in its portfolio. Workmanship, audiophile properties, concept and flexibility allow the “Made In Germany” trademark to shine in the best light and offer the user craftsmanship at the highest level.

In addition to the very good controller properties, the product also offers an excellent headphone amplifier, which, thanks to the crossfeed function, offers a practical, first-class feature that, as far as I know, has only been offered by SPL in the Phonitor series.

An armada of excellent detailed solutions and top-class technology are only offset by the use of an external power supply and the very closely spaced headphone jacks, but this is not enough to really detract from the product.

All in all an outstanding product, which e.g. Currently one of the best that is available in this product category. The product is here to stay and is guaranteed to establish itself as a classic of this genre in the medium term.

TEST: KRK S10G4

 KRK loudspeakers have been a constant companion in the audio segment since they were founded in 1986, and in recent years they have also been able to establish themselves very successfully in the budget sector from their early days, which were almost exclusively aimed at pro users. The Rokit series in particular has appealed to many newcomers to the field of near-field monitors due to its comparatively good quality for little money, enabling them to take their first steps in the audio sector. In keeping with this, but not exclusively aimed at the same series, the company, which now belongs to the Gibson Group, now also offers the fourth generation of subwoofers called the KRK S10G4, the middle representative of the three variations called the KRK S8G4, KRK S10G4 and KRK S12G4 .

The construction of the KRK S10G4

The KRK S10G4 is a subwoofer for budget-class project studios. With dimensions (W x H x D): 479 mm x 341 mm x 310 mm and a weight of 15.88 kg, it is easy to handle and does not take up too much space. The stated power of 160 watts Class D may seem moderate at first glance, but the maximum level of 117.2 dB makes you sit up and take notice, as this value is significantly higher than what is normally offered in this class.

Of course, KRK's optical trademark was once again installed in the KRK S10G4, the yellow membrane, although it is interesting that the 8- and 10-inch subwoofer membranes are made of glass-aramid composite, while the 12-inch subwoofers Version is made of Kevlar. The crossover frequency approach compared to satellites takes some getting used to. Active subwoofers always have a built-in crossover, which helps reduce the burden of low frequencies on the main monitors and ensures a good balance between the two elements. I found it interesting that in addition to the crossover frequencies of 60, 70 and 80 Hz, the S10G4's crossover has a maximum high frequency limit of 90 Hz, which compares to equivalent subwoofers from other brands that can go up to 120 Hz or even higher , is not particularly high.

What does this mean in practice? To get the most out of it, pair the S10G4 with main monitors that can comfortably go down to 90Hz without breaking a sweat, which usually means larger monitors. Users with very small monitors should instead choose the S8G4, which has a maximum crossover point of 100 Hz and in this case relieves the satellites better. Overall, the subwoofer has a frequency range of 30 - 110 Hz.

In terms of feel, the KRK S10G4 leaves an extremely massive impression. The workmanship of the product, which was built in China, is impeccable and its appearance means it can be tastefully integrated into most studio setups thanks to its rounded corners. However, the KRK S10G4 does not have any feet or other support points, which is why the product comes with a rubber mat, which is intended to prevent the underside from being scratched and to decouple the woofer a little from the floor. However, as most readers will know, the correct placement of the woofer in the room and the perfect balance to the satellites are significantly more important in terms of a well-rounded sound than a resonant decoupling from the floor. More on that later.


The connections of the KRK S10G4

As expected, all of the KRK S10G4's connections are located on the back of the case. You can see at first glance that KRK doesn't save money when it comes to connection options. We have XLR symmetrical in / out, we have TRS symmetrical in / out and for the consumer sector we also have RCA unbalanced in / out, a variety that I have only very rarely encountered before.

The system also has a jack connection for a foot switch, which not only deactivates the subwoofer, but also removes the frequency separation from the satellites. A very good thing if you want to quickly switch between an extended bass range and regular satellite playback. Should you work in a rental or condominium that is probably not acoustically decoupled. In case of doubt, this circuit also makes it possible to reduce the annoyance with the neighbors, so that you can only switch on the subwoofer sound at certain times, as it works its way through the walls comparatively quickly due to the long waves. There is a small LED next to it that provides information about the operating status and whether the standby circuit has activated. Once again we also come across a multi-voltage power supply that enables operation from 100 to 240 volts, so that use abroad is no problem worldwide.

Using 4 small mini switches, the KRK S10G4 enables the following control options:

Input Sensitivity: a comparison between balanced and unbalanced signals with regard to input sensitivity.

Polarity: A phase reversal in case there are standing waves or phase cancellations within the setup.

Stand By: Deactivates the circuit that puts the woofer into standby mode after 30 minutes.

Ground Lift: To help with ground loops or ground problems in general.

Finally, we have the cold device socket and a fine fuse that is accessible from the outside. The KRK S10G4 can be operated upright or lying on its side; its bass reflex opening is on the front of the housing.


The KRK S10G4 in practice


As we all know, the correct placement of a subwoofer in the room, especially when it comes to smaller rooms, is a tricky matter. Especially with regard to the distance to walls, possibly also slopes or ceilings, it must be taken into account that bass frequencies, with their circular radiation behavior, behave completely differently than radiation-directed mids and highs. Another point is the perfect balance in terms of frequency distribution and radiation behavior between the satellites and the woofer. Therefore, you need to pay a lot of attention to the correct placement of the subwoofer.

Even if there is a persistent assumption in some circles that everything below 300 Hertz can be placed anywhere in space since there is no longer any spatial positioning, the aim is still to place the woofer in the middle between the two satellites, if possible . In a typical budget studio setup, this usually results in the woofer being used below the worktop in the foot area. In general there is nothing wrong with this placement, but in most cases it is only a matter of time before one of your feet kicks the speaker or perhaps even damages it. To avoid this, you can purchase a suitable speaker grille, which counteracts this problem. Personally, I would definitely include this product in my budget planning, especially since the price of €22 is very moderate.

As is well known, using a subwoofer is not a panacea for spatial inadequacies or low-bass near-field monitors. If the room is unsuitable for music reproduction due to its symmetry, its arrangement or its radiation characteristics, even the best subwoofer cannot prevent the end result from being anything but satisfactory. In addition, there are still different opinions as to whether the bass range is better reproduced with powerful satellite woofers or whether a separate woofer is used, which of course significantly reduces the load on the satellites, but also has a different sound behavior. Everyone has to decide for themselves what is the best solution for them.

To put it bluntly, for a price of under 400 euros, the KRK S10G4 offers a lot for the money. The sound pressure of the system is indeed exceptional for this price and from the first tones you are literally surprised by the large volume of the product.

However, this also leads to the problem that the woofer quickly has to struggle with standing waves in a rather moderate control room, which can only be gotten under control after intensive testing of the installation position. For example, in my Studio 2, where the control room is only about 15 square meters, it turned out to be a good placement
wasn't that easy, as the walls repeatedly led to an increase in the low bass range. Nevertheless, you quickly feel very comfortable with the woofer, as its large volume gives off the classic feeling of the woofer.

However, the radiation behavior of the woofer itself is relatively indifferent and, depending on the music material, can quickly lead to booming. Particular attention should be paid to which satellites the KRK S10G4 is operated with. All in all, you have to give the product a good rating because it brings a lot of the attitude of the pro range into the budget range and ensures a good feeling.

Conclusion

With the KRK S10G4, the protagonist of the yellow membrane has a subwoofer in his portfolio that has a very good price/performance ratio. The workmanship and connection peripherals are well above the norm in this price segment, and the system also impresses with its exceptionally high sound pressure. When placed correctly, the KRK S10G4 is a useful addition to weak near-field monitors, which may lack deep bass.

TEST: Koch Amps Supernova

 If you look up “supernova” in the dictionary, you will generally find an explanation along the lines of “the extremely bright flash of a star at the end of its life.”

I'm absolutely sure that when naming their new flagship, the Koch-Amps company wasn't thinking about the torching of the head at the end of a live show, but rather about the record 5(!) individual channels in a full-tube head .

People may prove me wrong, but as far as I know, this is the current pole position among amplifier manufacturers when it comes to channel diversity.

Although the company around Ober-Schrauber and mastermind Dolf Koch has earned an excellent reputation in the professional world with various amplifiers, such as the traditional Studiotone or the Powertone, which is very popular in the heavy sector (it is rumored that Paul Reed Smith wanted the company several times to have a kind of PRS amp manufactured there), the company's international breakthrough in popularity has so far failed to materialize, even though Carlos Santana, for example, left his Mesa Boogie behind after testing a Koch amp and took part in the show that same evening played this amp.



construction

A long history precedes the release of the Supernova Head. At the Musikmesse in 2006, Dolf Koch showed me a prototype that boasted the key points of the current model.

However, the incredibly high level of choice in terms of sound design gave me worry lines at the time, along the lines of “whether he can really handle it?”. When there was still no production model within reach at the 2007 trade fair, I saw my predictions of doom confirmed until the finished model with a bulwark of features finally saw the light of day in 2008.

The Supernova is available in a 120 watt mono version or in the 2x60 watt stereo version that I have. Both variants are identical in terms of the preamplifier and tone control, only the power amplifier concept and the associated FX loop configuration varies.

Total 8 pieces. 12AX7 in the preamp and 4 pieces. EL 34 in the power amplifier manage the complex sound design of the head,

Of course, the first thing that catches the eye is the high number of channels, of which 4 of the 5 channels actually have their own tone control (channels 1+2 bass, middle, treble - channels 3+5 bass, middle, treble, presence, channels 4+5 share a sound control). All channels can be varied in their final volume via two switchable master volumes.

But the real nitty-gritty begins on the control panel on the right, or on the back of the amplifier. A total of 14 mini switches, of which 9 are. Designed to be programmable, give an idea of what the user will face when needed.

The Supernova has 4 voicing switching options, specifically a bass boost (Low), a mid selector switch (Mid Shift), a treble boost (Bright) and a treble attenuation (HiCut).

The head also has switchable speaker attenuation, which emulates a more compressed (H), moderate (M) or open (L) speaker deflection at low volumes.

As an absolute special feature, the amplifier has an “OTS” (Output Tube Saturation) circuit that can be adjusted in drive and volume. This is a 0.5 watt power amplifier, which, however, is not designed to operate the speakers, but rather only adds the distortion behavior of a power amplifier, which is harmoniously designed to be diametrically opposed to a preamplifier, to the sound.

As we all (hopefully) know, a power amplifier distorts completely differently in terms of dynamics (interactive) and compression (velocity-dependent) than a strongly compressing and dynamically “flat-compressing” preamplifier. The OTS circuit now makes it possible to generate the above-mentioned sound parameters at room volume without having to use the “English setting” (death to the neighbors).

On the back you are almost overwhelmed by jack sockets. A total of 10 speaker outs (stereo power amplifiers!) allow any connection of individual speakers or their combinations.

And as if all of this wasn't enough equipment, Koch also adds a total of four (!) FX loops on top, two serial and two parallel ones with adjustable levels, three of them in stereo, of course, making a total of 15 sockets alone the FX loops! Ugh.....

In order to manage this variety of sounds, in the best case scenario you need a MIDI switcher or the optionally available Koch foot switch FS6 SN, which, however, costs a lot with an RRP of just under €260. The corresponding connection sockets are located on the left side of the back panel.


Practice

When you turn the amp on, you immediately notice the non-existent noise level of the amplifier, no hiss, no hum, nothing, even at high master levels.

As expected, let's start with channel 1. First of all, we have the option of choosing a “normal” or more high-pitched (bright clean) sound via the input jack. However, this socket only affects channel 1; the remaining channels are not affected.

And there it is, the very soft and very pleasing clean sound that you know from all Koch amps, always a highlight. I know musicians who only use this channel and do everything else with FX pedals. The sound stays clean until around 3 o'clock, then turns into the first harmonic distortions.

Channel 2 goes in the classic vintage rock direction, greetings from Australia's number one export hit. Wonderful crunches, very dynamic. But now, the secret weapon, I'm adding the OTS circuit.

Oh my goodness, what a sound! It's absolutely fantastic how soft and warm the power amplifier saturation suddenly colors the overall sound. AC/DC at room volume so that I can still experience that ;-)

Channel 3 now moves into the powerful hard rock corner. It's getting very British here, the old school of "New Wave of British Heavy Metal" in the style of the Iron Maidens or Birmingham's (former) Finest send greetings with controlled heavy crunch. Here, too, the OTS circuit helps to darken the sound significantly, even at a comparatively low final volume.

Channel 4 is already real high gain. Even with low preamp control, the sensitivity is very high and leads to distortion very early on. Hard dominant noise, often below the standard tuning, finds its customers here, without wanting to reduce the channel to this area of application.

Yes, and channel 5? Well, if you don't find the ultimate high gain here, you probably accidentally have an acoustic guitar hanging around your neck. Even single-winders elicit massive gain from this channel, with a corresponding increase in background noise, of course.

Now played with the voicing switches and the damping switch and the variety of sounds is almost too much. At some point you can no longer decide which sound you want to choose, especially since every sound you choose is in the range from very good to absolutely top class.

Even the highest gain levels never lack transparency, even the lightest crunch values have pressure and sound density. I am completely thrilled! EVERYONE can find a sound they like here, provided they have a minimum level of technical skills.

If there is anything about this head that is not absolutely top class, it is the somewhat poor instruction manual, which provides information about the functions of the amplifier, but does not present it in the form it deserves .

A few meaningful sound examples with an appropriate visual layout would work wonders here, in contrast to the usual stapled leaf look. But that's how it's always been with Koch, always a bit understatement, in the hope that the artist would recognize the qualities even without glossy marketing...


Conclusion

Anyone who knows me knows that I am generally not a fan of superlatives. On every corner you can find “the biggest”, “the best”, “the longest”, which in 99% of all cases turns out to be a pathetic marketing measure at RTL2 level or a hopelessly exaggerated self-assessment that is appearing more and more frequently. Just disgusting!

However, the quality, flexibility, sound and workmanship presented to me with the Supernova Head can only be considered with a maximum accumulation of rating points.

Detached from the exuberant number of “real” channels, the Supernova has an almost unmissable selection of sound options without losing sight of its own basic sound. The outstanding OTS circuit alone, coupled with a sonically convincing voicing circuit, would be worth its own review.

Objectively speaking, the Supernova is indeed one of the best amplifiers currently available on the planet due to its fantastic sound. Subjectively speaking, I'll go one better and say that it's THE best-sounding amplifier I've heard so far in my life!

It is completely clear to me that with such a, albeit subjective, assertion I am offering the greatest surface for attack that one can open up in the sometimes archaic blinkered camp of the guitarist faction, but hey, if you spend so much time and intensively dealing with amplifiers, you can you can give it a good smack every few years!

Today is the day. Supernova, it couldn't be better!

TEST: Koch Amps Superlead

 It's unbelievable what a few kilometers and a national border can do when it comes to popularity. While in our neighboring country, the Netherlands, the Koch Amps company is almost a permanent institution in the blues and rock scene, despite excellent products such as the Battleship Supernova or the Studiotone Combo series, the company is still somewhat of an insider tip in Germany latitudes. It can't be because of football; in fact, we Germans have a very strong affinity with the Anglo-American forefathers when it comes to our personal feeling of happiness when it comes to amplifier technology.

However, the whole thing only lasts until you accidentally stumble across a Koch product in a music store, a rehearsal room or at a music fair and lend it an ear. Then the wow and aha factor is immediately exposed like a logarithm and you ask yourself why you haven't had this company on your personal radar until now. This can be remedied, especially since Koch has a very hot iron in the fire with the Koch Superlead Preamp, which is once again preparing to expand one's personal horizons with a manufacturer name.


construction

Anyone who knows a little about the company's history around mastermind Dolf Koch knows that the Koch Superlead concept wasn't just whipped up overnight. Almost a decade ago, the company caused a powerful response in the musical forest with the Pedaltone, a 4-channel preamp in a stompbox design. The product sounded great, was very flexible to use, but struggled a bit with the dimensions and weight. This is where the Koch Superlead Preamp comes in, which is preparing to take on the flexibility of the Pedaltone, but as a kind of Swiss army knife preamp that can provide the necessary connections and sounds in almost every performance situation. The personal tube amp for the gig bag, so to speak.

Conceptually we are dealing with a 2-channel preamp, whereby the second channel can be boosted again, which ultimately results in 3 different sounds. A 12AX7 or ECC83 tube is used as the sound generator, which, in conjunction with a triple tone control, forms the basis of the pedal. Like the clean channel, the overdrive channel has its own volume control, paired with a gain control for the level of distortion. The intensity of the boost factor is fixed and cannot be changed. The sounds can be switched silently using two buttons plus their own LEDs.

In terms of dimensions, the preamp is comparatively moderate with dimensions (WxDxH) 13.2 cm x 20.5 cm x 6.4 cm and, with a weight of only 1.2 kilograms, can also be transported in a gig bag if necessary. The Koch Superlead gets its operating voltage from the included 12V power supply. In terms of processing technology, the product manufactured in Europe is once again way ahead, like all other Koch products. A solid steel housing, the best components inside the product, jack sockets screwed to the housing and smoothly running potentiometers speak for themselves. I also personally really like the purple used as the casing color.

Now let’s get to the connection options for the pedal. Anyone who thought they were looking at a classic tube booster will immediately notice when looking at the socket arrangement that this is a much broader concept. On the right edge of the housing, next to the input socket, there is a balanced XLR output for recording or P.A. Purposes to which a speaker simulation was switched and which has an additional ground lift. Next to it is the main output, which is optimized in terms of output level via a mini switch depending on the application in front of a clean amp, a power amplifier, or the FX loop return of an amp.

On the left of the housing there is an unbuffered, upstream pre-FX loop for connecting an external preamp, a buffered post-FX loop for connecting classic modulation or room effects, a remote control connection for external management, the input for the Included power supply and an additional 200mA output to supply other stompboxes with sufficient operating voltage. A very intelligent and sophisticated signal panel.

Practice

In order to enjoy the full range of the Koch Superlead, you should briefly take a look at the different areas of application. Mind you, this is a preamp, not a classic overdrive pedal.


Example 1.) – the Koch Superlead as an upstream pedal

Do you have a simple transistor amp that has enough volume, but an insignificant clean sound and a typical “chainsaw massacre overdrive” sound? In this case, the Koch Superlead is connected between the guitar and the clean channel of the amp, which is equivalent to a three-channel tube amp.


Example 2.) – the Koch Superlead as a preliminary stage

Do you have a power amplifier on hand, in case of doubt also a 19" car that was swapped for the lighter and louder Class D power amplifier when the P.A. was last cleaned out? Use the Koch Superlead as a preamp, connect one or more cabinets behind the 19" power amplifier and the guitar system is ready!


Example 3.) – the Koch Superlead as an amp extension

Do you have an amp with a good-sounding power amp and an FX loop, but are disappointed in terms of distortion in the overdrive channel and warmth in the clean channel before the associated preamplifier? Put the pedal tone in the return of the loop and you have combined the pedal tone as a preamp and your power amp. This function often proves to be very helpful at festivals. Marshall Heads from the TSL or DSL series are usually borrowed as the standard backline for the guitarist, which are then used by all local bands. With the Superlead in the FX loop you get your typical sound without having to transport your own top parts.


Example 4.) – the chef superleads directly into the P.A.

Do you play in a band that needs to sound good even at low volume? Maybe in a dance or cover band, where after the first bars of the first number, the “Guitar quieter” signs are held up in the back rows? With the Superlead via the speaker simulation directly into the mixer and listen to your sound via the monitor system.


Anyone who has ever played a Koch amp knows that Koch amplifiers all have an excellent, clean sound with a high level of warmth and character. Many musicians actually only use the clean channel of the amps to create the various overdrive areas with their favorite stompboxes. Aware of this, the clean channel of the Koch Superlead is also characterized by a high level of detail and a warm basic sound. The sound control intervenes tastefully, sometimes subtly, in the action. Alternatively, the channel can also be used as a booster to continuously increase the output level of the instrument.

If you switch to the Overdrive channel, you quickly notice how well the Dutch company is at home in blues and rock. The sound is smooth, creamy and has just the right amount of saturation to compress the tone without feeling like a limiter. The dynamics are retained even at high gain settings, and the pedal also hangs very well on the guitar's volume control and takes over the musician's personal style of playing.


Conclusion

With the Koch Superlead, the Dutch company once again has an excellent product that will attract attention. As the little sister of the Pedaltone, the product scores points in all areas due to its intelligent circuitry and excellent sound and should definitely be tested in view of its great flexibility.

In the vast landscape of guitar effects pedals, few innovations have captured the imagination of musicians quite like tube-based effects pedals. These pedals, which incorporate vacuum tubes (or valves) into their circuitry, offer a unique warmth, richness, and dynamic response that is highly sought after by guitarists seeking to capture the elusive magic of vintage tube amplifiers. The story of tube-based effects pedals is a fascinating journey through the realms of technology, craftsmanship, and musical innovation.

**The Early Days: The Birth of Tube Technology**

To understand the origins of tube-based effects pedals, we must first delve into the history of vacuum tube technology. Vacuum tubes, which were the primary amplification devices used in electronic equipment prior to the advent of transistors, were first developed in the late 19th century by inventors such as Thomas Edison and John Ambrose Fleming. These early tubes laid the groundwork for a revolution in electronics, enabling the development of everything from radios and televisions to amplifiers and effects pedals.

**The Emergence of Guitar Effects Pedals**

The use of vacuum tubes in guitar amplifiers dates back to the early 20th century when pioneering inventors like Les Paul and Leo Fender began experimenting with ways to amplify and shape the sound of the electric guitar. The introduction of effects pedals, which allowed guitarists to alter their tone and create new sonic textures, soon followed.

The earliest guitar effects pedals, such as the Maestro Fuzz-Tone and the Electro-Harmonix Big Muff Pi, relied on vacuum tube technology to achieve their distinctive sound. These pedals utilized simple circuits consisting of one or more tubes, capacitors, resistors, and potentiometers to generate and manipulate audio signals, resulting in effects like distortion, overdrive, and fuzz.

**The Golden Age of Tube-Based Effects**

The 1960s and 1970s marked a golden age for tube-based effects pedals, with numerous manufacturers releasing innovative and influential designs that would shape the sound of rock and roll for decades to come. Brands like Vox, Marshall, and Electro-Harmonix introduced iconic pedals such as the Vox Wah-Wah, the Marshall Supa Fuzz, and the Electro-Harmonix Electric Mistress flanger, each of which utilized vacuum tubes to achieve its signature sound.

One of the most notable tube-based effects pedals of this era was the Electro-Harmonix Big Muff Pi, which became synonymous with the fuzz-laden tones of artists like Jimi Hendrix, David Gilmour, and Billy Corgan. Featuring a circuit design based around four cascading transistor stages, the Big Muff Pi offered guitarists a thick, saturated distortion with a unique harmonic character that set it apart from other pedals of its time.

**The Decline and Resurgence of Tube-Based Effects**

By the 1980s, advances in semiconductor technology had led to the widespread adoption of solid-state components in guitar effects pedals, relegating vacuum tubes to the realm of vintage and boutique equipment. However, as digital modeling technology began to dominate the market in the late 20th century, a resurgence of interest in analog and tube-based effects pedals began to take hold among guitarists seeking a more organic and responsive sound.

In recent years, several manufacturers have capitalized on this renewed interest in tube-based effects pedals by introducing modern interpretations of classic designs, as well as entirely new innovations that combine vintage tube technology with modern features and functionality. Pedals like the Catalinbread Belle Epoch Deluxe and the JHS Pedals Bonsai Overdrive pay homage to iconic tube-based effects of the past while incorporating modern conveniences like tap tempo, expression pedal inputs, and preset storage.

**Conclusion: The Legacy of Tube-Based Effects Pedals**

In conclusion, the evolution of tube-based effects pedals is a testament to the enduring appeal of vacuum tube technology in the world of guitar amplification and effects. From their humble beginnings in the early 20th century to their continued relevance and influence in the 21st century, tube-based effects pedals have left an indelible mark on the history of music, shaping the sound of countless recordings and performances across a wide range of genres.

As guitarists continue to seek out new ways to express themselves and push the boundaries of sonic exploration, tube-based effects pedals remain a cherished tool for those who value the warmth, richness, and dynamic response that only vacuum tubes can provide. Whether recreating the iconic tones of the past or forging new sonic frontiers, tube-based effects pedals continue to inspire and captivate musicians around the world, ensuring their legacy will endure for generations to come.

TEST: Koch Pedaltone

 Preface:

An all-tube amp, small like a pedalboard but with the dynamics and tonal volume of an official head and, if possible, suitable as an all-in-one solution for almost all live and studio situations. Which guitarist hasn't felt the need to own such a construction?

Anyone who regularly moves their top speakers around for shows or recording purposes or, at the latest, as happened to me on my last Asian tour with my band DOMAIN, has a flight to the venues, would really appreciate a transportable solution without sacrificing sound appreciate.

Knowing the purpose of such a solution, the Dutch company KOCH AMPS has brought the Pedaltone onto the market, an all-tube preamp in a floorboard design that is intended to solve precisely these problems.



Construction:

The Pedaltone is a 4-channel tube preamp equipped with four 12AX7 preamp tubes. The special feature of the pedal tone is the fact that the amp is equipped with a 0.5 watt tube amplifier. The output of the power amplifier is not enough to sufficiently drive a 4x12" cabinet, but its area of application is only used for the important sound shaping in the power amplifier segment.

The Pedaltone comes in an extremely solid sheet steel construction with dimensions of 31 x 23.5 x 8.5 cm and a weight of 3 kg. Four solid rubber feet secure the device against unintentional movement in hectic everyday life on the stage. In the lower area there are 4 switching relays which carry out the following switching processes:

- Switch 1: Channel change 1 / 2
- Switch 2: Channel 2 Boost / Channel 1 Enhanced
- Switch 3: Poweramp on/off
- Switch 4: Volume Solo / Rhythm

Using the configuration mentioned above, a total of 8 different sounds can be accessed using a foot switch, plus two different volumes. In the area above the switches there is a control area divided into three sections and recessed for protection purposes:

- Channel 1 – volume control plus 2-band tone control
- Channel 2 – gain/volume control plus 3-band tone control
- Solo / rhythm volume adjustment plus volume and distortion level control power stage

There are 4 tubes in the head area, which are protected and ventilated by a cut steel sheet. In addition to the connection for the included power supply, the back of the device offers a variety of connection options, such as an output to a power amp, an output for the return of an FX path, a headphone output, a frequency-corrected output for P.A., a guitar input, a cleaner output for a guitar amp and a serial input buffered FX loop. In addition, the enhanced mode, a sound preset that makes the clean channel sound a little more “airy”, can be switched off with a small switch.


This offers a wide variety of areas of application for the pedal tone. Here some examples:

Example 1.) – the pedal tone as an upstream pedal:

You have a transistor amp whose outstanding characteristics are sufficient volume, but an insignificant clean sound and a “chainsaw massacre overdrive” sound. In this case, switch the pedal tone between the guitar and the clean channel of the amp and you have a complete 4-channel tube amp at your disposal!


Example 2.) – the pedal tone as a precursor:

Do you have a power amplifier on hand, or if in doubt, a 19" car that was left over from the last P.A. cleanout? Use the Pedaltone as a pre-amplifier, connect the cabinets behind the 19" power amplifier and the guitar system is ready!


Example 3.) – the pedal tone as an amp extension:

Do you have an amp with a good-sounding power amplifier and an FX loop, but are rather disappointed with the preamp that comes with it? Put the pedal tone in the return of the loop and you have combined the pedal tone as a preamp and your power amp!
I use this function very often at large festivals, for example. On such occasions, a standard backline is usually provided by the organizer, usually consisting of the usual TSL or DSL models along with cabinets from Marshall. In this case, I only use the power amplifier of the same amplifier and still have the entire range of sounds of the Koch available without having to transport large top parts.


Example 4.) – the pedal tone directly into the P.A.:

Do you play in a band that needs to sound good even at low volume? Maybe in a cover band where the “Guitar quieter” signs are held up in the back rows after the sixth bar of the first number? The pedal tone directly into the mixer and listen to your sound via the monitor system, it can't be quieter!



Sound:
Well, a power amplifier in a preamp, what's the point of that, some might ask. “My preamp from Asia-Heinz from Hinter-Thailand is really distorted even without a power amplifier, you know...”. Just ask your local music retailer about this kind of customer, they will sing you a polyphonic song about it for 2 hours ;-)

Let's first take a look at the clipping behavior of a preamp and a power amp. If we leave aside all the technical terminology of the “big” amplifiers, e.g. about the return current interaction of the amplifier with the loudspeaker etc., the distortion behavior of the two components can be roughly (!) divided as follows:

A preamp tube reacts very quickly to incoming currents after it has been driven into saturation, which means that it distorts very quickly and can be driven evenly to a more or less high level of distortion, depending on the components used. It processes the incoming signal in a relatively “equalizing” manner, i.e. signals that differ in volume are reproduced with a relatively small difference in sound. For example, if the musician plays a part with high dynamics and large differences in volume, these parts are relatively “equalized”.

A power amplifier tube, on the other hand, works with dynamic distortion, i.e. the artist's personal dynamic playing style is supported by this circuit in terms of sound technology. Loud peaks are reproduced with greater distortion and higher compression, while quieter passages remain in the clean range.
To be more precise, it is exclusively this specific sound behavior that has ensured the tube power amplifier's stable survival in a world dominated by transistors and semiconductors. Even if the emulations of a tube power amplifier are getting better and better and the logarithms of digital amplifiers are constantly being refined by various manufacturers, at the moment no circuit design, no matter how sophisticated, can accurately reproduce the archaic design of the tube dinosaurs.

Let's start with the clean sound. What many people probably don't know is the fact that Koch have a very good reputation for their clean sound. Some endorsers actually only use the clean channel of the amps and generate all other sounds via floor pedals. Even in the pedal tone, the clean sound (channel 1) is beyond any doubt. Warm, soft, a touch of the legendary Fender ambience wafts from the speakers. Do you have a bulky transistor horn that only delivers an angular or clinical clean sound? Put the pedal tone in front of the amp and you will be amazed at how warm your amp can sound. The additional Enhanced switch gives the sound a high “sparkle” content if necessary, very nice for cleanly plucked things or funky riffs. When the volume is fully turned up, channel one also saturates and the first harmonic distortions are introduced.

If we go to the second channel, the response of the board changes fundamentally. It is much more compressed than in the clean area, and the sound development is also much more flexible thanks to the three-band tone control. Slightly distorted to strongly distorted calibers can be configured here. An even control path ensures a seamless transition within the distortion level. If you now press the boost switch, the distortion fraction kicks in. Depending on the feeding instrument, the result is an even tube board that still guarantees transparency.

But now let's come to the novelty of the pedal, the power amplifier. Even though all the sounds so far have been completely convincing, there is still no question that it is just a great-sounding preamp, which, like all preamps, has to make do with limited dynamics. Anyone who has ever tried to get an AC/DC sound a la JTM45 from a preamp or a moderately turned up tube amp will quickly notice that such attempts usually result in undynamic preamp distortion. Have fun and listen to channel 1 in a clean setting with the power amplifier turned up to full volume. All I'm saying is: damn close! Of course, a cute 12AX7 can't reproduce the stroke of one of the big bottles like the EL34 or 6L6, but the fact that such a sound is even possible with a floorboard deserves a very honorable mention! The second channel plus additional power amplifier is also a great cinema, the sound behaves exactly like a full-sized top including saturation and dynamics. Everything from light crunch to heavy hard rock is included here.

You have to be careful with the “All-The-Way-Through” setting, i.e. channel 2 plus boost plus power amplifier saturation, as it can slip into mud, especially with humbucker-supported guitars, as there is simply too much of a good thing in terms of distortion.


Conclusion:
Who would have thought that there would be an amp designer in “Oranje Land” who could stand up to the overwhelming power from overseas or even the German model manufacturers with his products. Despite excellent products and constantly growing popularity, Koch-Amps has still not overcome the status of an insider tip, especially in Germany. However, products like the Pedaltone ensure that the brand's reputation will continue to rise steeply. Rarely have I come across such a useful and outstanding sounding product with great practical value.

Depending on the equipment and area of application, the Pedaltone closes the gap between portable entry-level equipment and professional cutlery that requires a lot of transport effort by upgrading what is already there or supplementing what is coming.
