TEST: Radial Engineering DI Boxen

 What does the common sound engineer / producer / sound engineer do when he wants to impress his colleagues or customers? He shows his expansive consoles, his high-performance DAWs or his elaborate monitors, or P.A. components. What he is guaranteed not to show are the small, inconspicuous little helpers, mostly the size of a cigarette pack, without which a proper signal flow would not be possible either in the studio or on stage.

The diverse manifestations of the D.I. Box, the device that converts, sums or simply adjusts high-impedance and low-impedance, or symmetrical and asymmetrical signals along with all their connector variants, so that they can be further processed in the best quality by the targeted signal manager. Doesn't sound really exciting, but it's one of those areas where small mistakes cause big problems that can't be repaired later in the signal flow.

Aware of this, there is a whole smorgasbord of D.I. Boxes that give the different signals the necessary processing options. It's hard to believe what kind of constellations you can deal with these days.

construction

What all Radial Engineering products have in common is their high-quality mechanical design. The housings, made in Canada, are made of solid sheet metal and should easily withstand tough everyday road use. On the underside of the case, a glued-on, continuous foam rubber plate offers a good grip even on smooth surfaces.

The product range in detail:

Radial Engineering SB-1

The little one from the StageBug series, which comes in a blue case, is also listed as the SB-1 Acoustic, since its primary area of application is feeding an acoustic guitar into a P.A. is. However, since the product can also process an e-bass or line signals, such as those coming from moderate keyboards, the decision was made to change the name. As an active DI box, the product can run with 48V phantom power, which almost every mixer offers.

The product provides an unbalanced jack input along with a tuner output, which can also be used to feed an acoustic guitar amp. The two holes are right next to each other and just about allow for two massive Neutrik plugs in terms of distance. Milled clean! For signals with high output power, a PAD switch can be activated with -10 dB. For any feedback that may occur, the phase can be changed using another switch, a ground lift attached to the side of the housing, which can only be activated/deactivated with a pointed object, suppresses any mains hum that may occur. The output is via a standard XLR cable.

Radial Engineering SB-2

The Nato green version of the StageBug series is largely identical to the SB-1, although it is a passive version and is primarily dedicated to very powerful signals such as active basses or keyboards. Dj equipment also finds an optimal converter from asymmetrical to symmetrical here.

A special feature is the auto merge function, which routes a stereo keyboard from the input and the thru input to a mono channel when both inputs are used. In this way, channels can be saved if necessary. The phase switch has been omitted, all other functions are the same as the SB-1.

The result is an extremely high-impedance signal and a preamp that's ripped up to the hilt, but mostly doesn't manage to eliminate the harsh basic sound. This is where the Radial Engineering SB-4 can work wonders with its unusual 5 megaohm input. In addition to a phase switch and a ground lift, the product also has a high-pass filter that starts at 150 Hz with 6 dB / octave. The practical knowledge of the Radial crew is also evident here. A standard low-cut filter that cuts in at 80 Hz would cut low on an acoustic stringed instrument, while the rumble section at 150 Hz is a much better choice, especially in live situations.

Radial Engineering SB-5

Another specialist enters the stage with the SB-5. The mini-jack stereo cable fixed to the side quickly reveals its area of application. We're talking about iPads, iPhones and notebooks, whose internally built-in audio outputs cannot be beaten in terms of sensitivity and operational reliability, but sometimes have to be managed.

The Radial Engineering SB-5 is therefore designed somewhat differently than its colleagues, despite the same dimensions. It also has PAD and ground lift switches, but the signal, which is mostly in stereo, can be output via two symmetrical TRS jacks on the right / left or via an XLR jack in summed mono. Optionally, you can also purchase an L-bracket for this product, with which you can attach the Radial Engineering SB-5 to a rack or desk.

Radial Engineering SB-6

The Radial Engineering SB-6 takes the flexibility of a DI box to the next level. The product, which is consistently based on stereo, takes on several functions that can cause problems in the studio and on stage. On the one hand, it takes over the classic function of a stereo DI box, i.e. with the shortest possible unbalanced cables in the box and with symmetric cables of any length out of the box.

The next function, eliminating a power loop between two balanced audio devices, but powered by different circuits. Here a so-called potential difference can cause strong mains hum. The same applies to guitarists who want to play through 2 different amplifiers at the same time. In order to avoid the life-threatening masking of the protective conductor on one of the amplifiers, you can, for example, go from the guitar into a stereo effects device, isolate the two outputs via the Radial Engineering SB-6 and then feed them into the amplifier. In addition to the separate ground lifts, this is also achieved by changing the polarity of the left channel in order to avoid phase cancellations.

Radial Engineering SB-48UB

The Radial Engineering SB-48UB shows its qualities the moment you want to send a condenser microphone through a stage amplifier or an effects pedal. Most products of this type only have unbalanced inputs, so the incoming signal must be converted beforehand.

The DI Box comes with its own power supply and supplies either 12 or 48V phantom power. A standard XLR socket is used as input, the balanced and unbalanced output can be used simultaneously.

Radial Engineering SB-48 power bar

The Radial Engineering SB-48 Powerbar is a pantomime generator, which also comes with its own power supply (15 V - 400 mA). The product supplies two microphones or similar with either 12 or 48V phantom power if the connected mixer cannot supply the same.

Radial Engineering BT Pro Bluetooth

The highlight at the end of the list. According to modern sound technology, an ambitious technician should nowadays have a Bluetooth D.I. have a box at the start. The BT-Pro comes with the same Built-As-A-Rock feel, which suggests a long service life, especially since the pulled-over housing tabs additionally protect the ground lift switch, the mono summing switch and the headphone volume control. Unfortunately, the headphone jack is only a mini jack. Both signals can also be isolated to eliminate ground loops.

Conclusion

All Radial Engineering DI boxes shine with a very good sound, excellent workmanship, small dimensions and very good practicality. Whenever a signal needs to be converted symmetrically, Radial Engineering offers the right little box, it's just a matter of finding the perfect area of application.

- DI Boxes: The Essential Link for Seamless Audio Integration

Introduction:
Direct Injection (DI) boxes, also known as direct boxes or DI units, play a crucial role in professional audio applications, bridging the gap between different audio systems and ensuring a seamless and reliable audio integration process. Designed to convert unbalanced, high-impedance signals into balanced, low-impedance signals, DI boxes are indispensable tools for musicians, audio engineers, and recording studios. This comprehensive report explores the principles, applications, types, and advantages of DI boxes in the world of professional audio.
Principles of Operation:

At their core, DI boxes serve to solve impedance and signal level mismatches encountered when connecting instruments and equipment with different signal characteristics. Most musical instruments, such as electric guitars and keyboards, produce unbalanced high-impedance signals that are susceptible to noise interference and signal loss over long cable runs. On the other hand, professional audio systems, mixers, and recording interfaces typically require balanced, low-impedance signals for optimum performance and noise rejection.
DI boxes work by utilizing transformers or electronic circuitry to perform the following functions:

a. Signal Conversion: DI boxes convert unbalanced high-impedance signals from instruments into balanced low-impedance signals suitable for professional audio equipment.

b. Ground Isolation: DI boxes provide ground isolation, which helps eliminate ground loop hum and unwanted noise caused by differences in ground potential between connected equipment.

c. Level Matching: DI boxes often feature attenuation controls to match the output level of the instrument to the input level of the audio system.

Applications of DI Boxes:
DI boxes find widespread application in various audio scenarios, including:

a. Live Performances: Musicians and bands use DI boxes on stage to connect their instruments, such as electric guitars, basses, and keyboards, to the front-of-house mixing console or monitor systems.

b. Studio Recording: In the recording studio, DI boxes are employed to capture clean and direct signals from instruments before applying further processing or amplification.

c. Broadcast and Film: DI boxes facilitate the integration of instruments and audio sources into broadcast and film productions, ensuring pristine audio quality.

d. Corporate Events and Conferences: In corporate settings, DI boxes are used to interface laptops, media players, and audio equipment for presentations and speeches.

e. Public Address (PA) Systems: DI boxes play a crucial role in connecting musical instruments to PA systems in various events and venues.

Types of DI Boxes:
There are several types of DI boxes available, each designed for specific applications:

a. Passive DI Boxes: Passive DI boxes rely on transformers to perform signal conversion without the need for external power. They are simple, robust, and cost-effective, making them suitable for most live and studio applications.

b. Active DI Boxes: Active DI boxes incorporate electronic circuitry and require external power, usually through batteries or phantom power from the mixing console. Active DI boxes provide higher impedance matching, increased headroom, and sometimes additional features like EQ and phase reversal.

c. Stereo DI Boxes: Stereo DI boxes are designed to accommodate stereo signals from keyboards, digital audio players, and other stereo sources, providing separate inputs and outputs for left and right channels.

d. Reamp DI Boxes: Reamp DI boxes reverse the DI process, converting balanced, low-impedance signals back into unbalanced high-impedance signals. This allows musicians and producers to send pre-recorded tracks from a DAW back to amplifiers for re-recording and tonal manipulation.
Advantages of Using DI Boxes:

DI boxes offer several advantages that make them indispensable tools in professional audio applications:

a. Noise Reduction: DI boxes provide ground isolation and balanced connections, minimizing noise and interference in audio signals.

b. Signal Integrity: DI boxes preserve the original tone and dynamics of instruments, ensuring accurate sound reproduction.

c. Cable Length Compensation: DI boxes allow for longer cable runs without signal degradation, making them ideal for live performances and large venues.

d. Versatility: DI boxes can be used with a wide range of instruments and audio sources, making them valuable assets in diverse audio setups.

e. Troubleshooting: DI boxes help troubleshoot ground loop issues and impedance mismatches in audio systems.

Conclusion:
In conclusion, DI boxes are essential tools that bridge the gap between instruments and audio systems, ensuring seamless integration and preserving the integrity of audio signals. Their versatility, noise reduction capabilities, and ability to match impedance and signal levels make them invaluable assets in live performances, studio recording, broadcasting, and a variety of professional audio applications. As the audio industry continues to evolve, DI boxes will remain fundamental devices for audio professionals seeking clean, reliable, and high-quality signal transmission.

TEST: Quested V3110

 Anyone who deals with the big names in studio sound reinforcement technology will sooner or later come across the name Roger Quested. The very reserved British gentleman has shaped several decades of rock / pop music with his Quested loudspeakers and has been able to get credits in collaboration with names such as The Rolling Stones, Pink Floyd, The Kinks, Paul Simon, Cat Stevens, Rick Springfield and Led Zeppelin in his note life's work. A man of his caliber therefore also knows the big "recording temples" that a studio of his time resembled and which, depending on the owner, resembled a cockaigne of audio engineering due to the gigantic sales that could still be made with music at that time. Control rooms offered space for more than 3 people, so it was a matter of course to place at least one decent midfield monitor in the acoustically optimized room. Just such a monitor called Quested V3110 is available to us for testing today.

Concept and construction of the Quested V3110

Even before I could see the two studio monitors, I was already aware of the caliber of the Quested V3110. 2 massive boxes, each over 40 kg, wanted to find their way into my Meadow Studios. Due to a lack of friendly cooperation from some colleagues, I was forced to lift the 40 kg boxes onto the speaker stands alone and believe me, I have rarely been so happy to have completed a regular fitness program in recent years. With dimensions of 380 mm x 600 mm x 360 mm, the housing dimensions are still comparatively moderate, but this does not change the massive inner values of the system.

The experienced reader can already imagine where and how these monitors are used, for the interested beginner here are the key points again. With an output of 700 watts from a 10" woofer, 150 watts from a 3" mid soft dome and also 150 watts from a 1.125" soft dome tweeter, it makes no sense to place the monitors in a room that does not have at least one Floor area of approx. 40 - 50 square meters, more is better. Not that you have to drive these monitors, which offer an output of about 1 KW and a sound pressure of max. 120 dB, constantly at 110 dB, but loudspeakers of this size have to “breathe” in order to be able to play out their full sound. If you assume a sitting position of a near-field monitor, the loudspeakers thunder into your ears at medium to high volume levels to such an extent that the "inherent compression" of the hearing sets in and you no longer have a neutral perception of dynamics and frequencies. Good for “showing off your pants” in front of third parties from outside the industry, but completely unsuitable for their actual function.

With a basic price of just under €4,000 per box, the budget planning will probably be done for the majority of interested users anyway, because anyone willing to spend €8,000 for a monitor pair has certainly also built an acoustically optimized room, in which he can exploit the potential of an interception of this magnitude.

The case

Anyone who has not yet noticed which country the Quested V3110 comes from, when you look at the external appearance, you suddenly realize that these boxes can only come from the UK. I don't want to be carried away by an optical assessment of the Quested monitors, but the menagerie of dark blue back and black housing, wrapped in a finish along with a "down-to-earth" appearance, which would be found much more frequently in live sound reinforcement, does have a visual recognition value , but I don't think they look very good, especially when you consider the retail price of the cars. However, this is purely a matter of taste.

In terms of workmanship, no errors can be found, all components are cleanly processed and offer no reason for criticism. In contrast to many other monitors, the Quested V3110 has two bass reflex openings placed to the right and left of the tweeter, which offers slightly different radiation characteristics. Quested explicitly points out in its manual to optimize the seating position of the engineer so that the hearing is in line with the tweeter. This requirement alone cannot really be adequately implemented in a near-field position. What you should have in the back of your mind, especially with regard to the weight of the monitors, is that you get help with the installation or any conversion process that may arise. In particular, the soft dome domes of the tweeter and mid-range driver are constantly in danger of being dented at a careless moment, since there is no protection against external influences for said loudspeakers.

When the system is activated, the front panel Standby button will briefly illuminate red, then turn a 'pumping' blue as the system warms up. When this phase is complete, the LED will be solid blue. Should there be a performance limit due to the volume (which I can't imagine with the best will in the world with the system), the LED lights up red continuously.

The backside

The back of the Quested V3110 is very tidy and self-explanatory, in addition to the fact that it is traditionally kept in the typical Quested blue. A single XLR / TRS combo socket offers the input area, RCA was omitted for understandable reasons. The woofer can be readjusted by -3 dB, -9 dB and +1 dB using a recessed adjusting screw, while the tweeter and mid-range driver can each be raised or lowered by +/- 1 dB using 2 DIP switches. In addition, there is also an input level controller, which is also sunk, the on/off switch and the cold device socket together with a fine-wire fuse. For those who are technically interested, a circuit diagram for the signal flow is also printed. As I said, factual, clear and self-explanatory.

The Quested V3110 in practice

One or the other will have asked in the previous paragraph why the woofer reduction of the Quested V3110 can have an impact of up to -9 dB. This question is immediately answered as soon as the first tones sound from the monitor. The mighty 10 incher really hits the bass so hard that one would never dream of looking for a subwoofer for the purpose of an additional connection. On the contrary, although the very powerful bass sound immediately spreads a lot of physicality and, as a result, at least as much fun, it can quickly become a bit too much of a good thing, depending on the room dimensions or personal preferences, especially if you are listening to classic near-field monitors. So -9 dB is a decent number, but it can actually make sense depending on personal preferences.

The general sound of the Quested V3110 could hardly be more British, that is to say, the box colors the sound material a little, but in the best sense. Similar to other British products such as Neve, which is attested to have a very “own” sound in the best sense of the word, the Quested V3110 also has an extremely characteristic sound coloration, which, however, significantly increases the feel-good character depending on the signal fed in. If you pay attention to the seating position suggested in the manual, the system convinces with a very fine mid-range reproduction, which is particularly beneficial for guitar-heavy productions. The 3-way system can score here with a much more even reproduction than a 2-way system. The tweeter is also pleasing, but the reproduction is very "flattering" and less analytical than is known from comparable systems, just very "British" in the best sense of the word.

What clearly sets the Quested V3110 apart from many of its competitors is the extremely high headroom that the system offers the user when required. The behavior reminds me a little of my Tesla, with which you normally cruise comfortably at about 120 km/h on the Autobahn, knowing that in a tricky situation you can easily outperform any other vehicle in terms of acceleration. The Quested V3110 also leaves a very relaxed impression at normal listening volumes between moderate and slightly ambitious, knowing that with this system you can also briefly listen to the sound of your production in the open air area or in the trendy scene club at 2 a.m. in the morning, if that's all are filled, can be checked for practicality.

All in all, the Quested V3110 convinces in terms of sound across the board and also offers adequate sound reinforcement for larger control rooms, which knows how to convince with an outstanding bass and a fine mid-range resolution!

Conclusion

With the Quested V3110, sound reinforcement legend Roger Quested once again has a worthy representative in his portfolio. The midfield monitors offer a classic British sound with finely resolved mids, a powerful bass component and a very large headroom, allowing you to work in a relaxed manner at almost any volume.

If you have a professional recording studio with the right ambience and are looking for the right A monitor, you should definitely try the Quested V3110.

TEST: Quested V2108

 It is and will always remain questionable whether there is a "British sound" in the field of monitors, and if so, which protagonist stands out from the crowd. For all proponents of this thesis, the British manufacturer Quested Monitoring Systems will probably be one of the first names that spontaneously come to mind, as the manufacturer enjoys an excellent reputation worldwide, especially in the pro sector. The company, which was founded by Roger Quested, has actually managed to stay in the top quality segment until today, while maintaining complete independence. With the Quested V2108, the manufacturer now presents an improved new edition of its model to continue to compete in the Champions League of nearfield monitors.

Design and optics of the Quested V2108

I don't know if it's due to the isolation of an island for thousands of years, but the British have always had and continue to have a very, shall we say "unusual" relationship with colors as soon as one enters the field of audio technology. Those who remember the "Villa Kunterbunt" layout of old analog British consoles, e.g. from old Midas or Soundcraft, know what I'm talking about. Comparatively defensive is the appearance of the Quested V2108, although you can immediately recognize in which country the monitors are developed and manufactured. Only a British company will probably dare to combine a dark anthracite as a base with a dark blue metallic with a discreet hammered look in the amplifier area. United Kingdom, here we go!

The company looks back on a long history in loudspeaker manufacturing. Already in the mid-eighties the foundation stone for the career of the company was laid with the H108, at that time still in the usual, passive design. The basis for the V2108 available here for testing is the VS2108, which should develop until today as the cornerstone of the Quested portfolio. According to the press release, the current version should be characterized by higher dynamics and improved midrange reproduction. With an individual price of 2,509 euros, the speaker is also in a league where it must compete with several competitors for the crown of the top class. Let's see how the Briton does.

First impression

Oops, I had forgotten how "haptic" near field monitors can be. With the dimensions of 340 mm x 400 mm x 365 mm and a stately weight of 23 kg, placement on the desk is definitely out of the question, an official pair of stands is called for here, not only for space reasons, but also to not "water down" the massive cube in its foundation. Also in terms of performance, the Quested V2108 is not too far from the midfield, the system has a total of 400 watts, which are supplied from 2 Class A / B power amplifiers. However, the distribution of power is interesting, since both the high frequency range of the 2-way box, which is implemented by a comparatively large 28 mm soft dome, as well as the low frequency range, which is reproduced by means of an 8 inch driver, is supplied with 200 watts each in equal parts. This means a comparatively strong overabundance of power for the tweeter range, which, however, proves to be very helpful in a very relaxed reproduction even at higher volumes. As usual for Quested, the tweeter comes without a waveguide and sits open with a slight camber in front of the front wall. Therefore, be careful when transporting the box, the soft dome is dented faster than you would like.

Quested points out in its communications several times that especially the midrange, which is inevitably with 2-way systems always in the area of the crossover frequency (here 1.4 kHz) somewhat underexposed, should be significantly better positioned in the new system. Otherwise, the system has a frequency response of 45 Hz - 20 kHz ± 2dB / 38 Hz- 22 kHz -6 dB, which makes a subwoofer not absolutely necessary. Below 20 Hz, the frequency response is cut off with -3 dB at 24 dB/octave. In general, the speaker processing makes a very interesting impression. For a peak of 200 watts, the very stiff cone of the woofer is hung comparatively softly with a very elastic surround, which, in cooperation with the two bass reflex ports on the front bottom, suggests an interesting bass reproduction.

The back

As already mentioned, the rear of the monitor stands out in several respects from the standard layout of a nearfield monitor, on the one hand by its unusual color scheme and on the other hand by the three-dimensional milled, very bulky appearing heat sink for the running operation. Regarding the connection options, as usual in this performance class, the asymmetrical RCA section has been completely omitted and instead a single, locked XLR / TRS combo jack has been installed.

In terms of treble and bass compensation, it is once again quite "British" to the point, that is, 3 different control options equal three different layouts! The closer sense of this action does not really open up to me, but that's the way it is. While one needs a small slotted screwdriver for the recessed, ninefold lowerable input level control, the fourfold tuned bass control (40 Hz and below, -3 dB, -9 dB, + 1dB) requires a medium sized slotted screwdriver or at least a firm fingernail for the adjustment. The treble adjustment, in turn, is controlled by 3 DIP switches and allows, in addition to flat, + / - boost / cut above / below 2.5 kHz. Cold device plug, power switch, ready.

The Quested V2108 in practice

Well then, as sound material once again the usual suspects were used, i.e. uncompressed and unprocessed high-end stereo recordings for example of drum sets, single tracks of vocals, various test tones, several reference mixes and a few masters of my current productions, for which I am responsible myself. Completely from the gut, should one have to press the basic sound of the Quested V2108 together, I would spontaneously think of the adjective "analytical" with all its advantages and disadvantages.

First of all, let's start with the impulse reproduction and the spatial staggering. In both areas, the system can only be given top marks. All instruments are picked up very cleanly and reproduced in a detailed and punctuated manner even at high volumes. The excellent reproduction of vocals is particularly striking, revealing far more nuances than one would normally expect from a 2-way speaker. The spatial staggering allows the depth of the room not only to be guessed at, but also to be really grasped, which makes it much easier to reproduce depth in the reverb area, especially in the mix down.

In terms of volume, a somewhat more ambitious level brings out the strengths of the monitors better, although the system also cuts a good figure at low volumes. I placed a special focus on the midrange, which, according to the manufacturer, has improved significantly compared to the predecessor. And indeed, the monitor convinces with a significantly improved midrange reproduction, which is particularly noticeable in the instrument genre of distorted guitars. The important range between approx. 1 kHz to approx. 2.5 kHz is picked up well despite the crossover frequency, which is probably due in particular to the fast response of the woofer.

Only light or also some shadow? Well, as we all know, you can only evaluate the sound of a monitor very subjectively, so any description should always be taken with a grain of salt, but I personally was not convinced by the bass response of the Quested V2108. I have the impression that Quested has sacrificed some bass volume in favor of the admittedly very good midrange reproduction. The bass range is comparatively "bony", euphemistically also to be called "neutral", and does not convey the low end that the product's physical features would suggest. Even when activating the bass compensation by +1 dB, the basic sound did not generally become "bigger", but merely conveyed a more stable sound reproduction.

I didn't want to let this statement stand in the room quite so simply, however, and created a cabling that I hadn't considered necessary shortly before. And lo and behold, in cooperation with an Eve Audio subwoofer, the monitors blossomed after a short tuning. Now the speakers could completely show their strengths and gained immensely in volume and linearity. To what extent a corresponding subwoofer use makes sense, everyone must ultimately decide for themselves, for me personally it was the decisive point that the Quested V2108 still lacked to the upper class area.

Conclusion

With the Quested V2108, the British manufacturer has a worthy successor to the VS2108 in the program. The monitor has an outstanding impulse fidelity, high power reserves, a very good depth gradation and an excessively good midrange reproduction for a 2-way system.



On the other hand, those who focus on a voluminous bass reproduction should consider the additional purchase of a subwoofer despite the 8-inch woofer, but this ultimately remains a matter of taste.

TEST: QSC KW 122

 What hasn't everything changed in terms of sound reinforcement in recent years. Active speakers of a third of a man's height work with power in the kilowatt range, sometimes in price regions where you might have gotten just 6 crates of beer for in the past. Due to Asian manufacturing, one has secretly become accustomed to the same price regions and it may seem rather unusual for some, why products of the above category were or are originally located in the four-digit euro range.

It was all the more astonishing for me to receive a product from the aforementioned segment with the note "Made In USA" from a manufacturer that I previously knew only from the power amplifier sector. The same amplifier from the American manufacturer QSC has been doing an impeccable job in my recording studio for over 20 years. It's a pleasure to get to know a member of the new House-Of-K family, which, in addition to its unusual manufacturing area, can also offer a few other equally unusual features.


Construction

The QSC KW122 is an active multi-function full-range system, which is a two-way system consisting of a 1 inch tweeter and a 12 inch bass speaker. The speakers are protected by an extremely sturdy grille plate, the rest of the cabinet is covered with a resistant textured paint. Three very sturdy recessed grips allow for good handling of the construction, and there is also a Direct Tilt high stand flange on the bottom of the cabinet, which allows for a straight setup or a 7.5 degree tilt. The overall workmanship of the case can be described as exemplary and very solid.

All models from the K-series have the power of 1000 watts in common, with the designation W, the cabinets are also made of comparatively light but sturdy birch plywood, a construction method as used in Marshall 4x12" guitar boxes. Unusual is the splitting of equal parts of 500 watts each to the tweeter and woofer, respectively, which however leads to an increased protection of the tweeter against clipping peaks. As expected, the power is generated by a Class D power amplifier, which is characterized by a compact design and low heat development. Should heat build up nevertheless occur, the proprietary GuardRail system and a built-in fan intervene.

In terms of dimensions, the product measures 660 mm x 381 mm x 391 mm with a weight of a comparatively moderate 22.2 kilograms. The technical key data are quickly dealt with, according to the manufacturer, the construction has a frequency response of 53 Hz - 18 Khz at - 10 dB and a maximum sound pressure of 131 dB peak, measured at a distance of 1 meter. The system has a total of 8 pieces of M10 flying points and can therefore be positioned in any orientation in flight. Due to its trapezoidal shape, the KW122 can also be used as a powerful floor wedge. Although the power output also suggests, as a drumfill I would recommend the system because of the 12-inch woofer used only in an emergency.

Striking for a system of this design is the extensive connection periphery of the system, where especially on the daisy chain use was placed great emphasis. Two independent combo jacks allow both a console connection and the direct connection of a microphone or a high-impedance instrument such as an acoustic guitar. The level of both inputs can be adjusted independently via a rotary potentiometer in 20 steps. If required, the same signals can be looped through directly to another component via 2 XLR outputs. The mixed signal is also output via a third XLR out if required. For the connection of an MP3 player or similar, 2 Cinch connectors are available. For fixed installations, an external 10 kOhm volume control can be connected via a three-pin remote gain.

The two driver sections can be divided into different presets via two sliders. For the bass range, the settings "NORM" (standard full range), "EXT SUB" (subwoofer operation, crossover frequency at 100 Hz) and "DEEP", (bass boost with internal limiter circuit as protection against distortion) are distinguished. For the high frequency driver, the settings "FLAT" and "VOCAL BOOST" are available, a filter preset that specifically boosts frequencies affecting the voice. The blue LED on the front of the cabinet can indicate either the operating status or the use of the internal limiter.



Practice

First test area, an MP3 player. The first thing that stands out is the conspicuously large volume jump between grid position 2 and 3. This is no problem when connecting a mixer with separate volume control, but when connecting a non-adjustable output, the delivered volume for background pause music could already be too loud in position 3, but barely perceptible in position 2.

However, the signal quality coming out of the speakers is of a very high quality. A very powerful bass, which already delivers a soft, but still defined low frequency range without the Deep circuit, a successful crossover frequency, which doesn't contain the notorious midrange hole, which tends to occur with a 1"/15" combination and a high frequency range, which never works in the limit range thanks to overdimensioned power reserves. In general, one seems to literally feel the power reserves in the high frequency range; at no time, even under heavy use, does the high frequency range seem angular or even edgy.

There are also no failures to report when using the microphone. The sound reproduction is balanced, the speech intelligibility good. In terms of dispersion, the conically shaped tweeter driver, which is aligned at 75 degrees, is particularly convincing. It is noticeable that QSC tunes the two speakers to each other, i.e. both speakers have the same dispersion behavior. The acoustic room illumination is unusually even, even strong lateral radiation is mastered very well within the aforementioned angle and ensures a good sound image even in the close range of the speaker.



Conclusion

With the K-Series, QSC has a real trump card up its sleeve. The system is mature, quickly expandable and of very high quality, both acoustically and in terms of processing. Easy daisy chain expansion allows the system to be expanded almost at will, especially since up to five speakers can be powered from a 10 A, 230 V line.

The KW 122 is a comparatively small, but incredibly powerful active loudspeaker, which covers a wide range of professional applications through flexible application possibilities.

Be sure to test it!

TEST: QSC KS118

 What do you want from a transportable subwoofer for live use? In addition to an opulent sound pressure level in the low bass range, it should be very well manufactured, robust in every respect and, as the order already mentioned, it must be transportable and, if possible, can be handled by only one person. QSC is launching the QSC KS118 for exactly this purpose, so let's take a look at how it performs in this regard.

The construction of the QSC KS118

No matter how hard you try in the design department of a manufacturer, the tiresome triumvirate of sound - robustness - weight simply cannot be fooled. The fact that, thanks to Class D technology, it is now possible to design active sound reinforcement systems in the kilowatt range with an ease that was undreamed of even years ago would have been unimaginable in the days of passive systems. The power amplifier issue is thus off the table, but the moving air cannot be subjected to any technical trickery.

Thus, among other things, it is the speaker system, but above all the road construction, that still wants to be moved and should also provide the necessary counterweight for a vibration-free reproduction. To say it right up front, QSC has done a great job here. Although a weight of 49 kg is not to be thought of carrying for a 1-man company, QSC has installed 4 high-quality, smooth-running heavy-duty transport rollers on the back of the cabinet, which do a very good job once you have balanced the woofer on the back. Incidentally, the QSC KS118 is the successor to the KW181, which in turn has enjoyed a good reputation in the scene for many years.

Mind you, the woofer first has to be balanced on the back and who doesn't know the problem that the rollers develop a life of their own from an angle of about 45 degrees and if they are not somehow braked, "run away" from the bending point. However, QSC can't do anything about this; unfortunately, it can't be avoided. In general, everything possible has been done with the QSC KS118 to ensure that the product arrives safely at its destination, no matter how it is handled. Especially if you order the very high-quality protective cover right away, which in addition to a pocket for power or signal cables over several Velcro straps not only the cover itself, but also on top of stored products, such as the satellites, to attach knows... Logically, these roles automatically make the QSC KS118 a rolling cart.

The cabinet of the QSC KS118 is constructed of 18 mm birch plywood, which generally enjoys a good reputation, especially since a large part of the world-famous Marshall 4x12" guitar speakers are also made of this material. The cabinet is covered with a resistant textured lacquer, which should withstand at least rudimentary external influences. As additional protection for the speaker opening, the cabinet is closed from the front with a solid grille. With dimensions of 640 mm x 520 mm x 785 mm, you're already dealing with a full-grown subwoofer in the compact range, which can be moved by one person thanks to the heavy-duty casters, as long as you have the appropriate ramps in the loading area. Lifting the product alone is hopeless.

The QSC KS118 has 4 adjustable feet each on the bottom and one side panel, while the opposite side has analog 4 recesses for daisy chain stacking. Well thought out, well executed. If you now think that mentioning such a matter of course is exaggerated, you should take a look at the competition to see what kind of crude solutions are sometimes expected of the user in this regard.

On the top of the case is an M20 threaded flange that works with all common spacer rods. Of course, QSC also has corresponding rods for the in-house tops in their program.

The electronics of the QSC KS118

With 3.6 KW peak power, we are then already in the range where you can not only hear the bass, but also feel it. To get the most out of the system, an 18-inch long-throw driver works inside the cabinet, offering a frequency response of 35 - 111 Hz at a maximum level of 136 dB.

The system is monitored and controlled by an extensive DSP, which, in addition to various safety circuits, also has a few helpful tools on board. A small but easy to read display navigates through a standard menu, which is self-explanatory and requires no study of the manual.

In terms of crossover, you have the choice between 80 and 100 Hz, depending on which crossover point the satellites offer. Depending on the placement of the woofer in the network, you can set a delay of up to 100 ms, which corresponds to a distance of about 34 meters. Depending on the application, various DSP settings can also be saved and recalled accordingly. Interesting and not self-evident in this range is also the Cardioid Radiation mode, which of course requires at least 2 woofers of this type. Finally, you can activate a DEEP mode, a kind of bass boost that boosts the low frequencies even more.

The QSC KS118 has 2 inputs, both of which have appropriately looped outputs for daisy chain operation. Both inputs are controlled in parallel with an input control, which boosts the input signal up to 10 dB if required. The necessary cooling is provided by a speed-controlled fan, which runs quite quietly. Finally, there is also the On / Off switch and the power plug on the back.

The QSC KS118 in practice

In order to be able to evaluate the QSC KS118 in context, I received a complete setup, consisting of 2 QSC KS118 and two corresponding satellites from QSC plus the distance rods, so that I had a total of almost 11 KW of power available. In the context of this setup, the woofer really left an excellent impression. This woofer can really get very, very loud, but cushions the peaks with a very large headroom in an almost relaxed manner.

It was also interesting that when the crossover frequency was changed from 100 Hz to 80 Hz, the low bass range was reproduced a tick stronger. Not striking, more subtle. In general, the QSC KS118 succeeds again and again, despite the almost ostentatious performance specifications, to complete its task very discreetly in the background, just as one would wish from a subwoofer.

The situation is similar in DEEP mode. Here, too, the system is comparatively discreet, but also leaves no doubt that the boost has been activated. It is truly impressive what the system gets out of just one speaker when optimally tuned.

I fed the system with various test tones and reference recordings. As is almost always the case with audio reproduction, as the volume increased, heavily mastered material tipped over into an aggressive mush at a certain point, while a live recorded drum set banged without any processing whatsoever that it was a joy. Not really new, but always worth a mention.

The preset Cordioid preset is also a great relief when it comes to quickly curbing the notorious booming frequencies behind the subwoofers towards the stage via phase cancellation. Stack or position them next to each other, insert the preset, done. Alternatively, you can of course use the delay for a corresponding noise cancellation by placing two woofers one behind the other, which, as is well known, requires corresponding tables and is always only a compromise in terms of frequency cancellation. For an optimal implementation for the QSC KS118 system, however, you need 3 woofers, 2 front-loaded and one rear-loaded with appropriate phase rotation.

Conclusion

The QSC KS118 is a top class product on the active subwoofer market. The system features sophisticated DSP control, exceptionally high headroom, very good build quality, and high practicality.

You need one person to roll it, 2 people to carry it, and in return you get an excellent woofer that delivers just under 22 KW of bass with, for example, a 2-way cardioid arrangement in front-rear-front alignment. This is enough to provide a club with adequate and ambitious sound. QSC once again shows their great experience in the subwoofer field and has created a worthy successor to the KW181 with the QSC KS118.

TEST: PSI Audio A 14-M

 That our alpine neighbors south of our republic can also manufacture high-quality monitors was proven not long ago by the Swiss company PSI with their product PSI Audio Active 17M. Inspired by this success, the company has now set out to make a mark one step smaller in the form of the PSI Audio Active 14M Studio Red, but not without acquiring an optional subwoofer, in our case the PSI Audio Sub A125-M Studio Red, an additional boost in the bass range.

Even if the name PSI Audio should not mean anything to many people, owner and company founder Alain Roux and his Relec Sa group of companies, to which PSI Audio also belongs, are well known to experts. That Switzerland is anything but a low-wage country should be known to everyone, but whoever enters the fray with a retail price of just under 1,100 euros per speaker for a small monitor and 2,495 euros for the matching subwoofer, either has real cojonnes, or his product is sonically above criticism. We are curious.

Special features

As with its bigger brother, the A 17M, PSI Audio brings out the big guns in terms of optimized playback in this version. With the in-house Compensated Phase Response System for a frequency-optimized phase correction and the Adaptive Output Impedance System for an optimization of the transient response of the diaphragms, PSI Audio tries to generate a better depth gradation, higher detail resolution and an optimized impulse response.

Big claims, considering that the tiny speaker with its tweeter driver and its 6 inch bass speaker has only the dimensions 163 mm x 243 mm x 170 mm available to generate a balanced sound image. However, the very small dimensions offer many advantages where space can be at a premium, such as home studios or OB vans.

Construction

The near field monitor is designed as a 2-way monitor and has a 30 watt tweeter along with a 70 watt woofer, which are separated at 3.5 Khz by an active crossover. Colored in burgundy metallic, the box leaves a very noble impression, although one should handle the product with care. The paint doesn't offer real protection against external influences; even lightly pushing it over a surface causes scratches on the bottom of the case. The PSI Audio Active 14M Studio Red is completely manufactured at the company's headquarters in Yverdon / Switzerland. The bass reflex port of the cabinet is oriented to the front, which offers great advantages, especially for placement close to the wall.

Rear

On the rear, things are spartan. Equipped with a stepless volume control and a roll-off control, which allows the reduction below 100 Hz by a maximum of 10 dB, there is only one XLR socket on the back. The placement of the controls naturally offers the possibility to design a visually appealing case front, but has the disadvantage that you have to decide on a setting in advance for a fixed installation close to the wall, unless you want to constantly remove the monitor from its place for a readjustment.

In this context, you should also pay attention to the setting of the roll-off controller, which plays a decisive role when placing the monitor on the wall or in a corner, as well as when using a subwoofer. The lack of other connections such as TRS, RCA or even just a combo jack unmistakably shows that PSI considers all other connections irrelevant, i.e. budget solutions are not the target audience of the PSI Audio Active 14M Studio Red.

Subwoofer

With the PSI Audio Sub A125-M Studio Red, PSI Audio offers a sonically tuned subwoofer, especially regarding the frequency range downwards. As you can see from the frequency diagram, the working range of the subwoofer starts exactly where the PSI Audio Active 14M Studio Red runs out of steam, if you disregard a discreet dent between 50 - 70 Hertz. In return, the PSI Audio Sub A125-M Studio Red delivers a linear coverage of the bass range up to 35 Hertz. Strictly speaking, the subwoofer only reproduces the range between 35 - 50 Hertz linearly, below and also above that, the curve of the woofer equipped with an 8-inch drops sharply.

Visually, the satellites and woofer complement each other perfectly, both have the same look. The aforementioned CPR and AOI systems were also installed in the woofer. However, the subwoofer, which is specified with 150 watts of power, has an impressive weight of over 20 kilograms with average dimensions of 320 mm x 480 mm x 385 mm, so it is recommended to think about the subwoofer's location in advance.

In terms of connection field, the PSI Audio Sub A125-M Studio Red is also quite spartan. 2-way input right / left, plus the forwarding of the signal to the satellites, a volume control - that's it. No variable crossover point, no daisy chain, nothing. Well then.

Sound

Let's start with the PSI Audio Active 14M Studio Red without subwoofer. The first sound impression: neutral, perhaps even unobtrusive in the best sense. While many nearfield monitors draw attention to themselves during initial operation with a typical AHA effect of bass-heavy, harsh highs, squawking mids or even fine highs, soft bass or whatever, the PSI Audio Active 14M Studio Red shines by not attracting attention with any peculiarity at all. Maybe a little sharpness in the high mids just above the crossover frequency, but that is a purely subjective and moreover subtle listening impression.

The speaker reproduces the sound material without any glossing over, but also doesn't make you cringe in the old MS-10 manner in the sense of "there's still a lot to do". Rather, it reveals details that can still be adjusted in the later mix in a discreet manner, as one would wish. Frequency-wise, it goes down quite linearly to about 100 Hertz, below which, as expected, it's closing time with these cabinet dimensions in cooperation with a 6 inch speaker.

However, the PSI Audio Active 14M Studio Red shows its great strengths in the spatial resolution. The depth gradation is exemplary, whereby the phantom center can be located excellently due to a very good stereo imaging. The impulse behavior is also very balanced and reproduces almost all instruments very naturally, regardless of the volume. Here, the neutral character of the monitor comes into its own very well.

Only in guitar-heavy productions does the ear have to be prepared for a slightly sharp basic posture with high-gain guitars. However, once you get used to the discreetly biting character, you will get along very well with the system.

As expected, the sound changes enormously when the subwoofer is added in the low bass range, but in a different way than I would have expected. From 50 Hertz, the woofer now pushes very strongly, but it displaces the sound material with an extremely soft response. The PSI Audio Sub A125-M Studio Red truly makes you feel the frequencies more than hear them. Any form of attack or even impulse sounds soft as if packed in absorbent cotton. Depending on the sound material, the basic orientation of the woofer is a real boon, but also offers the danger of "lulling". To what extent the concept corresponds to one's own listening habits is something everyone has to find out for themselves. Personally, I found the tuning a bit too soft, but this is not to be taken as a judgement.

Conclusion

With the PSI Audio Active 14M Studio Red, the Swiss company fulfills its expectations. As an extension of the product range in the direction of the smallest monitor, the company manages to fulfill the high expectations that the 17M generated. Whether in solo operation or in combination with a subwoofer, the product shines with a precise resolution, a very good depth gradation and a neutral sound image.

Especially in confined spaces, the PSI Audio Active 14M Studio Red can score with its small dimensions and offer a good sound even in spatially difficult workplaces. However, it remains to be seen whether the in my opinion somewhat too ambitious retail price of 4,700 Euros for a subwoofer combination will make interested customers hesitate.

TEST: Proel Session 4

 I admit that I had never heard of the Italian company Proel until now. After all, the company seems to exist since 1991 and has developed with the Proel Session 4 another product for the compact array area, which has emerged in recent years as the sales driver in the mobile sound industry. There is hardly a sound reinforcement manufacturer who has not sought his salvation in recent years in the separation of subwoofers and upright satellites and calls a typical representative of the array class his own.

The advantages of such systems are quickly outlined. The mobile systems should be small, transportable and dismountable, and due to powerful Class D power amplifiers, they should also be able to drive in the KW range. However, one should not be blinded by the array buzzword, because the compact solutions have absolutely nothing in common with a "real" array system. Let's take a look at what Italy has to offer.

Concept and construction of the Proel Session 4

Immediately after unpacking, one can see that Proel has written the adjective flexible very large in its Proel Session 4. Thus, the system can be operated in mono as well as in 2.1 stereo with the appropriate setup. The system, which consists of a subwoofer and two satellites, can be operated either mono with the two satellites on top of each other by interlocking the enclosures via a sliding device, or in typical stereo function with one satellite arranged above the woofer and a second to the left or right of it. In terms of dimensions, the system features an active bandpass subwoofer with 2x 6.5" woofers and 2 array tops with 4 x 2.75 Neodynium full-range speakers each.

For the woofer satellite a double screwable distance rod is included, for the second satellite a separate high stand for the 35 mm flange has to be purchased. Also, only a single Speakon cable is included with the system, which I absolutely cannot understand. A second Speakon cable would only increase the manufacturing costs by a few euros and at least leave a completely usable system. So the first thing you are forced to do is buy another Speakon cable. Clearly saved at the wrong end!

For transport, the two satellites are sunk into two corresponding tubes inside the subwoofer to save space. Very practical, but you should never forget to put the two tweeters in the supplied sleeves with the pull loop upwards beforehand, otherwise you will only get the satellites out of the slots again with great effort and manifold curses. In this case, you have to turn the woofer upside down and heave it upwards due to the millimeter-precise milled openings. You definitely only do that once, after that you remember the procedure. Further mounting points for cables or the spacer rods are unfortunately not available, a separate bag / case must be used here.

The Proel Session 4 is designed by its performance for small bands, moderate Dj or playback use in small locations. With 300 watts for the subwoofer and 100 watts per satellite (all continuous load data according to the manufacturer), you can make an unplugged combo or a moderate playing band audible for about 100 people. Physicality in the form of a punchy kick drum, for example, cannot be realized with this system. It is all the more important that the system draws as finely as possible even at low volumes in order to reproduce details in the sound shaping of a moderately playing band or corresponding playback material. More on this in the practical part of the test.

The operation of the Proel Session 4

Like most systems of this type, the manufacturer of the Proel Session 4 tries to keep the user as completely out of the technical part of the system as possible. What is certainly a blessing for the inexperienced occasional operator, leads on the other hand to the fact that fewer and fewer operators are seriously familiar with sound reinforcement material and above all can no longer actively intervene in the decisive parameters. Preset rules ...

Thus, the Proel Session 4 only has a rudimentary preset management of the usual suspects Music, DJ, Speech and Playback plus a simple 2-band EQ in front of you, with which you can shape the basic sound of the system a bit. Unfortunately, not even a parametric mid EQ has made it into the system, which would have been very helpful depending on the incoming signal. Probably the manufacturer was afraid of the user's incompetence and immediately denied him any capabilities. I know, parametric mids are a big challenge for the untrained ear, but to leave him completely out of the sound control because of that, I think is counterproductive and presumptuous. Further system management such as crossover frequencies, gain control etc. is unfortunately searched for in vain.

On board is still the popular, integrated Bluetooth player, so that the personal smartphone can keep the party going without a cable. Two XLR / TRS combo jacks are available as input sockets, which can also be looped through to other amplifier solutions via daisy chain via corresponding XLR outputs if required.

The Proel Session 4 in practice

The transportability of the Proel Session 4 is very pleasant. Even though the "pull-out-the-loops" solution for transporting the satellites is a bit shy, the speaker reduction to the subwoofer cube is very practical. With a total weight of 25 kilograms, a single person should make sure to only lift from the knees, but the weight can definitely be called moderate for the performance-related equivalent. I still recommend, if possible, to transport the system with 2 people on the two opposite transport handles.

The birch plywood case makes a good impression, the workmanship is impeccable, although the rather coarse textured paint makes the system look coarser than it is. The spacer rods can be connected to each other in a few easy steps, although you can of course only use the upper end. When it comes to adjusting the height of the satellites, the Proel Session 4 really is very flexible.

Already at the first frequencies that sound out of the Proel Session 4, the sonic preference of the system becomes clear. The system seems to drown in the bass range. However, the DJ preset was also activated, which is probably to account for the bass love of many productions. After switching to the Playback preset, the bass transparency improved significantly, but still delivered a very dominant bassiness that was comparatively manageable and didn't drift into an undefined slobber.

The Proel Session 4's weak point, on the other hand, is another. I'm inclined to say that the system lacks another speaker in the form of a high frequency driver. Up to the high midrange, the four tweeters/midrange drivers can maintain a hard but comparatively continuous sound image, but after that it's over. In the true high frequency range from about 6 kHz upwards, the reproduction collapses as if a medium wave radio is being transmitted. The sound is harsh and lacks any fine resolution.

This shortcoming cannot be remedied by the internal EQ either, since it only adds further harshness to the output signal. Possibly an upstream graphic EQ could still bring something in signal quality, but I fear that the internally installed tweeters also come here to their limits and can transmit the signal in its adjusted form only rudimentary.

Driving the system into saturation, once again the sonic design of the system comes into play. While the subwoofer remains surprisingly stable even into saturation, the tweeters/midrange speakers quickly add clippings to the signal due to their rather low power handling, which lowers the sound quality even more. A band playing quietly will never get into the embarrassment of this volume, but a system should nevertheless have enough headroom even at power peaks to absorb the impulse peaks accordingly clean.

Conclusion

With the Proel Session 4, the Italian manufacturer has a small, portable 2.1 speaker system in its range, which is easy to transport and quick to set up. The convincing sound in the bass range is unfortunately diminished by an insufficient treble reproduction, so I think that users should check in advance whether the treble reproduction is sufficient for their personal field of application.
