TEST: Alvarez MD 3500

 Preface:

I still remember the time when acoustic guitars were generally delivered without pickups and recording an acoustic instrument live turned out to be a real challenge for sound engineers and musicians. Most of the time all that was left was a highly disciplined body control on the part of the artist, as the only recording was a microphone that was as sensitive as possible and every slight turn of the body completely changed the sound. A relaxed style of playing or even an entertaining stage show was completely unthinkable.

Nowadays, acoustic guitars without pickups are clearly in the minority and can usually only be found at high prices or at extra low prices. Almost the entire middle class has factory-installed acceptance systems that follow various transmission principles. What is even more unusual is the fact that the Alvarez company is releasing the MD 350, a mid-range model in a classic style, i.e. without any acceptance systems. However, the instrument can also be purchased with an integrated acceptance system as an option. The instrument comes from the ambitious Masterworks series and, to my surprise, is not manufactured in Europe or North America, but in China.




Construction:

While unpacking the plain cardboard transport box, a top-class transport case emerges from the foam beads. It has a built-in hydrometer (!) to keep an eye on the room's humidity, which is extremely important for acoustic guitars. While electric guitars are comparatively resistant to dry air, acoustic instruments are very susceptible to low humidity due to their more delicate construction and higher unpainted surfaces. The wood shrinks and is accompanied by cracks in the paint and even complete deformation of the components. To prevent this situation, Alvarez has integrated the measuring instrument into the lid of the case, a very useful and commendable device!

In terms of size, the actual instrument can be assigned to a dreadnaught, a size that is only surpassed in size by a jumbo. Even though some musicians complain about the lack of handling with a dreadnaught, this size has now become established as the standard measurement for this type of instrument. Their advantages in terms of volume, loudness and sound development are too great compared to their smaller relatives.

When it comes to choosing wood, Alvarez takes a traditional approach. The back and sides are made of solid Indian rosewood, which belongs to the black rosewood genus. By the way, the wood known as “Rosewood” in English has nothing to do with the German term rosewood due to a translation error. The double-locked 5-piece neck of the guitar appears to be made of mahogany, but unfortunately no further details could be found. However, the grain and sound support the assumption mentioned above. Deep black ebony was used as the fingerboard. A narrow but relatively high version was chosen as the fret wire.

Six gold-plated Grover tuners perform impeccable service on the headstock, which is also veneered with rosewood. The peg ends are made of a black, very non-slip plastic, which blends in beautifully with the black color of the fingerboard. An inlay made of 2 opposite A's made of mother-of-pearl completes the overall impression.

The top of the instrument is of particular importance. It is solid Engelmann spruce, a pine tree that comes from western North America. The top is optically traversed by an even grain, which gives the instrument a homogeneous look. The sound hole is surrounded by a narrow rosette and two thin lines, all very simple and tasteful. The overall simplicity of the instrument is further rounded off by a combination of tortoise and a so-called herringbone binding. In fact, all of the visual decorations on the instrument are kept very discreet. For example, the instrument only has a small oval fingerboard inlay on the twelfth fret; the usual orientation aids on the third, fifth, seventh and ninth frets are completely omitted. So if you are used to orienting yourself on the fingerboard, you should change your habits to focus on the edge of the neck, where the usual dot inlays are available.

Fortunately, the MD 350 has also addressed the issue of octave purity. The patented direct-coupled bridge, also made of ebony, has an offset at the transition from the G to the B string, which equalizes the vibration behavior of the non-wound strings in relation to the wounded strings.


Playability:

When you hold the neck of the MD 350 for the first time, the first thing you notice is the very pronounced C profile. The middle of the neck protrudes from the shaping like a small spike, a fact that some people have to get used to. Interestingly, there are no disadvantages to this form, on the contrary. This shaping was particularly effective in the picking style, as it opens up a favorable angle for the transfer of force to the fretboard, depending on the shape and size of the hand. The fretboard radius is moderate and the neck width can be described as strong but not overly fat. In combination with the neck profile, the result is an almost triangular shape, which at first glance seems unusual, but nevertheless functional. Thanks to the compensated bridge, the detuning is kept within pleasant limits even at higher registers. This means that full chords can be intoned relatively easily up to the eighth fret; only from the tenth fret onwards does a clear interference become audible.


Sound:
Mid-open! ;-) What do you mean by such a catchphrase? First of all, you have to take into account that a brand new instrument still sounds a bit brittle and awkward. Especially with a purely acoustic instrument, the woods have not yet settled in and ensure a slightly stiff attack and a relatively hard finish. However, with an experienced ear and practiced estimation skills, you can roughly estimate how the instrument has found its tonal personality after around 300-500 hours of playing time.

After the break-in period mentioned above, the MD 350 has a good chance of offering a warm and voluminous sound within the wood parameters. The aforementioned choice of wood already gives a rough direction, which is then supported without exception in the sound test. The rosewood sides and back provide a high midrange content, which is slightly above the resonance frequencies of mahogany due to the harder nature of the wood. The ebony fingerboard and bridge slightly increase the degree of hardness, only to be somewhat relativized by the mahogany neck.

What I really like is the solid spruce top, which in my opinion is yet to find its true potential. Detached from this, the instrument already has enormous volume and will have no problems asserting itself in an acoustic setting.



Conclusion:
It is becoming more and more common to notice that China is developing from a pure “cheap wage equals cheap instrument” manufacturing country into an ambitious upper middle class manufacturer, a development that Japan also went through bit by bit at the time. The import of Western knowledge, implemented through cheap Eastern wages, has in recent years taken on forms that no one would have ever dared to predict. We will probably find out relatively soon how long the almost complete abandonment of environmental protection measures and the political situation will allow this economic upgrade.

Separately from this, the bottom line is that the MD 350 is a sonically remarkable instrument built of high craftsmanship, which offers good sound quality at a low price. Visually tasteful, I think it will find its customers very quickly.

TEST: Alto TS 115 Vibe

 It's always interesting to see how a segment in the music sector changes. Not only is almost every area that deals with sales and acquisitions in some form subject to certain fashion trends, no, there is also creeping change, which can completely remodel an area, driven partly by requirements and partly by financial considerations.

One of these areas in sound reinforcement is the transformation of the specialist into a flexible multi-tasker who covers several areas, depending on what is required of him at the time. Please do the whole thing with a comparatively low sales price and in a weight class that the singer can even load into her VW Polo on her own if necessary. What seemed unthinkable just years ago is one of the biggest trends in the industry, we're talking about the active two-way box, which, thanks to Class D power amplifiers, works in the performance range of entire vocal systems from previous decades and whose areas of application range from P.A., monitor, sidefill tasks to extends to mobile barker sound systems.

The Alto TS115 Vibe comes into exactly this area, which, in addition to its classic task, also has an MP3 player installed for additional flexibility, which is managed from the back of the product.

construction

With dimensions of 385 x 430 x 679 mm and a weight of 18 kilograms, the Alto TS115 Vibe is in a class that you can't easily tuck under your arm for transport. In return for the power rating of 800 watts peak, it is a product that is comparably easy to handle, as long as you don't expect your front woman to set up her sound system alone.

The moderate weight can only be achieved by using light neodymium speakers in the form of a 15 inch woofer or 1 inch tweeter driver and the operation of two Class D power amplifiers. The housing is cast from durable polypropylene plastic and has no sharp edges. Four stacking feet, 6 M10 upper, lower and rear flight points and a 36 millimeter flange on the bottom allow any form of positioning in modern stage operations. In addition, two handles embedded on the sides and a recessed grip on the top help with portability.

The housing is designed in a trapezoidal shape, which minimizes the risk of edge reflection. In addition, the product can also be used as a stage wedge at a 40 degree angle thanks to the same shape. In addition to a power cable, the scope of delivery also includes a clear operating manual, which provides information about the most important features.

A solid metal grille protects the internally installed speakers from mechanical influences and also prevents objects from entering the two front bass reflex openings. A blue LED on the front of the housing provides information about the operating status of the product. The product can be operated from 100 to 240V mains voltage via the voltage control, which is only accessible internally.

All control and connection options are located on the back of the housing and have been placed slightly recessed to protect against transport damage. At the top is the illuminated display measuring 65 x 15 millimeters, with the MP3 player's controls in the form of push buttons placed directly underneath. A USB stick or a MicroSD card is used to feed tracks; the appropriate sockets are located directly next to the player. The built-in player supports the formats MP3, the Windows-based WMA and the Apple codec AAC.

If you place a stick in the product, you will receive extensive information about the memory contents with the folder name, title display, playing time and remaining titles, with small symbols in the lower right part of the display indicating whether it is a USB stick or a memory card. A single volume potentiometer regulates the output volume, with a small slider underneath deciding whether the left, right or both channels are reproduced through the speakers in a monophonic mix. By the way, the mixdown works without any phase cancellation.

A contour pressure switch can be used to activate a loudness setting in “bathtub EQ” (bass and treble in, mids out), which makes the sound more “pleasing”. This setting is a master equalizer and also influences the tone control of the applied microphone or line signals. There are no other sound or dynamic processing options in the form of filters or compressors.

Additional connections include two XLR/jack combination sockets with separate volume control. The two volume controls manage both a microphone and an applied line level. In the position 7 o'clock up to 12 o'clock, line signals are managed, from 12 o'clock to 5 p.m. the microphone signals are processed. A built-in limiter, which announces its use with a red LED, prevents the internal speakers from being overloaded and automatically reduces the volume if the level is too high.

In order to be able to connect several components to form a daisy chain operation, the Alto TS115 Vibe also has an XLR output, which picks up the signal either before or after the volume control. To prevent hum loops when linking several active systems, the system also has a switchable ground lift. A comparatively quiet fan ensures sufficient cooling within the case.

Practice

When the power switch is activated, the system boots up silently without the infamous switch-on impulse. First of all, when exposed to music, the Alto TS115 Vibe impresses with its transparent, powerful basic sound, which generates a frequency-even reproduction. Even in the crossover range, which is 2.5 kilohertz in this design, there are no frequency drops or acoustic gaps. In order to use the internal MP3 player, the USB stick or the MicroSD card must be formatted in FAT16 or FAT32; Mac formats such as OS Extended etc. are not supported.

In return, the player supports all common sample rates from the underground 8kHz up to 48 kHz, but without the CD standard audio formats AIF and WAV. If you place a microphone at the appropriate input, the maximum volume is reduced slightly for feedback reasons. It makes sense for a quick start, otherwise the usual setup techniques must be taken into account. Unfortunately, the XLR plugs cannot be locked in the socket, which results in a loss of signal flow if the position is changed carelessly.

As a stage monitor in wedge positioning, the Alto TS115 Vibe also leaves a good impression, although the symmetrical alignment of the two outer parts unfortunately does not allow for different beam angles. For an average drummer, the system can also be used as a drum fill, provided you are not a Motörhead. As expected, moderate sidefill use can also be practiced, but club stage dimensions should not be exceeded. In the P.A. In this area, the box shines with good acoustic illumination and good power reserves with a comparatively low weight.

Conclusion

The ALTO TS115 Vibe is an all-rounder on the market that shines with very good key data. Peak power of up to 800 watts with a comparatively low transport weight of 18 kilograms, road-suitable processing as well as universal mounting options up to the flown version enable a wide range of applications in the area of stage and hall sound reinforcement.

TEST: Alto TS 310

 Ever smaller, ever more powerful, ever lighter, with the current active full-range loudspeakers there is actually only one direction with the maxim: how can I illuminate a maximum area acoustically with a minimum of transport effort. Another contender comes from Alto, is an offspring of the current TS series and also goes by the name Alto TS 310 and once again follows the principle “Designed in the USA, Made in China”. This test will show to what extent the box can hold its own in practice with a retail price of only €233

The scope of application of the Alto TS 310

The times of specialists seem to be receding more and more into the background and can actually only assert themselves on large, professional stages. The entire consumer sector is firmly in the hands of multifunctional boxes, which also include the Alto TS 310, although Alto is in this regard. put a few more spins on it. In addition to the standards such as high stand operation and floor monitor, the Alto TS 310 is also equipped with M10 flight points, which greatly increases flexibility in stationary operation.

What's interesting is that Alto puts a lot of focus on DJ operation with their product, so that a commercially available DJ mixer actually serves as a reference in the manual as an application example for 2 speakers. To what extent the speakers, especially in the bass range, The practical test will show that the requirements are met.

The construction of the Alto TS 310

The Alto TS 310 is an active two-way speaker, which is rated at 1,000 watts RMS and a peak of 2,000 watts, a value that is definitely in the upper range in this class. In the RMS range, the breakdown is 650 watts for the 10-inch woofer and 350 watts for the 1.4-inch neodymium driver, which represents an unusually strong focus on the tweeter in terms of power output. We will discuss later to what extent these values correspond to practical suitability. The separation is at 2.5 kHz, with the beam angle once again being 90 degrees horizontally and 60 degrees vertically. The frequency response is given as 54 Hz - 20 kHz at a sound pressure of 126 dB (SPL @ 1m)

With dimensions of 524 mm x 320 mm x 300 mm, the box is extremely handy and, with a weight of 11.8 kg, is also comparatively easy to transport. The housing made of polypropylene is impeccably crafted and protects the two speakers with a solid, black metal grille. The system has two handles on the sides, which in this size are usually sufficient for transport and balancing on high stands. If you want to keep the look of the boxes for a little longer, we recommend purchasing the optional protective cover TS210, which costs €28.

Both in the upright position and in wedge operation, the Alto TS 310 is held in place by 4 shaped feet (upright operation) or a small grooved surface (wedge operation), which are machined from the polypropylene. The stability ranges from good (upright operation) to sufficient (wedge operation), but the slip resistance can only be described as moderate due to the non-rubberized surface. All controls are located on the back of the housing and have been provisionally secured with two protruding edges to prevent them from breaking off. In addition to the box, the scope of delivery also includes a power cable and a multilingual, simple manual.

The connection options on the back of the housing have been kept very simple and include the management of 2 input sources, each of which can accommodate a jack, TRS and XLR with a combination socket. A gain control with 0 dB raster allows you to adjust the level between the line and microphone signals, and a red Peal LED helps with overloading. There is no sound control at all, only a contour switch provides a bit of a scoop/loudness feeling with an increase in the treble and bass range of 3 dB. For daisy chain operation, the Alto TS 310 also has an Since the system is passively cooled, the Alto TS 310 operates at a very low noise level, which offers great advantages, especially at small events.

In practice

As elegant as the surface of the Alto TS 310 may appear when delivered from the factory, it is also susceptible to scratches, so I definitely recommend factoring the costs for the protective cover into your budget. A worn-out box may still have some charm with the local punk combo, but it seems completely out of place when it comes to a presentation. Despite the stated values in the four-digit watt range, you should not ignore the practical key data of the box. A pair of speakers will be able to adequately provide sound for a small gathering of 50 - 60 people, but no more is possible.

I tested the system in three different areas. On the one hand as a wedge in a rehearsal studio, in high stand operation in a small hall and in high stand operation in a large open outdoor area.

The first sound impression with the Contour switch deactivated and the neutral tone control is decent. The bass range is surprisingly present, significantly more than I would have expected from a 10-inch device. The highs sound a bit busy, the midrange sounds comparatively balanced. You immediately notice that the tweeter, which is slightly larger than the standard 1-inch drivers, extends nicely into the high-mids and covers a significantly better mid-range content than what is normally offered in this performance class. A good start.

Pressing the contour switch changes the sound characteristics significantly. The treble range clearly gains in presence and character and the bass range is also pushed strongly, but stops just before the drone and holds the volume surprisingly well without tipping over. In this setting, the system will already be able to cover a large part of its range of application without having to use another EQ from the console or similar. However, restrictions must be made in the area of the “physicality” of the sound. It is truly impressive what bass the Alto TS 310 gets out of the 10 inch speaker and housing construction, but of course it cannot replace an additional subwoofer. As expected, the 10-inch device has physical limits that cannot be overcome even with the best design.

Let’s now come to the “eye-catchers” of the Alto TS 310, the performance specifications. I am still of the opinion that no company does itself a favor by using the last physically determined values as a hook and selling these to the customer as a standard. For every hobby speaker who basks in the number “2,000”, there are around 10 disappointed customers who expected more from the number. The fact is that the box is loud, even very loud for its size, but in the last performance range the previously good sound of the construction turns into an unpleasantly harsh, sometimes distorted sound, which significantly reduces the quality of the product.

Not only is the “2,000 watt” peak not reached in practice, you also don’t want to push the box to its limits in the power range below that, unless you want to turn to the experimental area of music. A targeted peak power of 1 KW with a reduction of approx. 600 watts would suit the system very well and leave a really good sound impression right up to the performance limit. In this way, however, you run the risk of burdening the listener more than pleasing the listener if you use the right amount of power.

Conclusion

With the Alto TS 310, the American manufacturer has an inexpensive full-range box with good sound and high flexibility in its range. The system sounds much more mature than what the dimensions suggest and offers a wide range of possible uses with a high stand, floor monitor and flight operation.

If the manufacturer were not, like many of its colleagues, to peddle unrealistic performance specifications and thus create expectations that cannot be met in practice, the box would leave an all-round successful impression. This leaves you with a very decent sounding box, where you have to be very careful with the control path in the last quarter of the volume controls.

TEST: Allpedal Devils Triad

 Some insiders will know Jeff Loomis from his work with “Nevermore”, but he made his final leap into the top league with his entry into “Arch Enemy” in 2014, where, in contrast to Michael Amott, who was primarily responsible for the is responsible for the composition work and takes over the virtuoso parts of the guitar work. I met both of them for a friendly chat at the Alpenflair Festival this year, as they both had the dressing room next to us and entered the stage after us. I was invited to watch their show from the stage, but I couldn't see whether Jeff Loomis was already using his all-pedal Devil's Triad OD/BST/REV/DEL, as he only had a large midi bar at his feet as a control center , although you can of course easily integrate your signature pedal into your setup using a looper. We have the same pedal for testing today.

The concept of the Allpedal Devil's Triad OD/BST/REV/DEL

Allpedal have come up with really nice packaging. Black, visually appealing packaging with a magnetic closure ensures a good first impression. There is also a marketing sticker and four stick-on feet if the pedal is not attached to a floorboard. The pedal itself also looks very appealing with its red, black and white skull appearance and should attract the attention of genre fans.

With his Allpedal Devil's Triad OD/BST/REV/DEL pedal, Jeff Loomis is taking up a trend that has gained massive popularity recently. We're talking about a pedal that reflects the artist's general basic sound, usually in the form of an overdrive/distortion pedal, has one or two preferred effects installed and, in case of doubt, can be used on any amp with a serial FX loop by using the FX -Return is used as a power amp and the pedal as a preamp. In this case, it is important to optimally adjust the output level of the pedal, as the combination preamp / pedal - FX return, preamp / pedal - external 19 inch power amplifier or preamp / pedal - input amp each require completely different output levels and, if adjusted incorrectly, one will be irrelevant produce a thin or muddy over-pressed sound.

The principle of the Allpedal Devils Triad OD/BST/REV/DEL, developed and built in the USA, is to accommodate four different effects in one housing, such as overdrive, boost, delay and reverb. The four functions share three ON-OFF switches, with reverb and delay having to share one switch. The entire hardware is completely black except for the boost controller, which comes in a bright red. The Drive, Reverb and Delay effects each have three control knobs, which are pleasantly stiff and have the following control options:

Drive FX: Drive: Analog op-amp with Soft Clipping 260K @ 1KhZ, Level: Off - 20db, Tone: 10db Boost @ 4KhZ | 15db cut @ 4KhZ - Gain: Increases Signal to the clipping LEDS to increase distortion.

Delay: Analog signal path with digital repeats. - Measured input impedance: 250K @ 1KhZ - Level: Volume of the repeats, dry signal always unity level. - Feedback: Number of repeats. - Delay: Time between repeats ~50ms minimum / ~500ms maximum.

Reverb: Analog signal path with digital plate reverb emulator. - Level: Volume of wet signal, dry signal always unity level. - Tone: Attenuates highs from wet signal only. - Decay: Sets the level of wet signal feedback.

Boost: Analog op-amp - Measured input impedance: 325K @ 1KhZ - Boost: Unity - 20db


Unfortunately, the labels on the respective controls are very small and can only be deciphered if you look closely. It is therefore best for the live situation to learn the respective control functions by heart if you want to access them during the show. The pedal itself is very solid, which suggests a long service life. The respective effects are each provided with an LED, which provides information about the on-off status, while a large red LED provides information about the applied mains voltage. With dimensions (W x D x H): 146 mm x 119 mm x 60 mm and a weight of 547 grams, the pedal still remains within the range of normal parameters. A standard 9V connection with a hollow plug is sufficient for the power supply.

In order to be able to use the total of four effects perfectly and distribute them on the respective amp, the pedal has an input and an output on the front for both the drive boost section and the delay reverb section. With the Allpedal Devils Triad OD/BST/REV/DEL, Jeff Loomis uses the Four Cable Method, which integrates the preamp section of the respective amplifier into the setup with the external pedal. With this method, both the pre-amp of the amplifier can access the effects of the effects pedal, and the pre-amp function of the pedal can access the power amp of the amplifier without having to go through the pre-amp. This generally allows for significantly greater flexibility in terms of sound than standard wiring.


The Allpedal Devils Triad OD/BST/REV/DEL in practice.

As expected, the Allpedal Devils Triad OD/BST/REV/DEL focuses primarily on high gain sounds of different stripes. The pedal offers a highly compressed basic sound, the sharpness of which can be adjusted somewhat. Even though many sound examples on the internet refer to hard rock or classic rock attitudes, yes, you can of course achieve good sounds with this pedal even at lower gain settings, but the primary application of this pedal is not rock, but metal. The interaction with the dynamics of your personal playing style is a bit too limited for a real rock sound, which means that the pedal irons out the level differences relatively strongly to an average level and primarily only differs in the gain range.

But this is by no means meant negatively, because a signature pedal should of course particularly reflect the characteristics of the respective artist in their preferred style and not be an all-rounder in the classic sense. As soon as we get into the metal area, the pedal can fully demonstrate its true strengths. Even at high gain settings, the sound remains comparatively transparent, both in rhythm and in solo areas. Provided you play cleanly, the high compression offers a good basis for pumping heavy sounds, also in the downtuning area.

The level, or boost function, deserves special attention, as the signal level can be increased to +40 dB by combining the two controls. This not only allows you to find the perfect level for the respective power amplifier response, as previously mentioned, but you can also use this boost function to drive somewhat discreet amps into a sweet spot in which the amp can offer its best sound quality. In particular, all-tube amplifiers that are designed to be relatively open in the output stage with a low scoop approach, such as Marshall, Hiwatt, Soundcity or similar, should benefit from the approach of the Allpedal Devils Triad OD/BST/REV/DEL.

In the area of the 4-cable method, the user also benefits from the sound quality of the reverb and delay units, which are spartan in their control but quite effective in their sound design. The two effects offer a good basis, especially if you want to give your guitar a subtle color in solo or clean passages.
For more unusual ambient sounds, I would like a slightly higher resolution and more complex control, but as I said, that's not what the pedal was designed for.

All in all, you have to attest to the pedal's sound being exactly the same as its namesake. The pedal works excellently in metal and all its varieties, which is what it was ultimately designed for. It fulfills the function of a full-fledged guitar preamp, especially for the working musician who has to travel with small equipment, so that you can use almost any amp on site as long as it has a serial FX loop.

Addendum: I initially operated the pedal with a 100 mA power supply, but this resulted in a lot of mains hum. This problem was solved with a current of 250 mA. It is therefore important to ensure that the power supply unit used offers sufficient mA.

Conclusion

With the Allpedal Devils Triad OD/BST/REV/DEL, the American company Jeff Loomis has tailored a pedal that cuts a fine figure in every style of metal. The highly compressed basic sound offers a good basis for pumping palm-muted actions as well as for sustain-rich leads.

In combination with an extensive boost function, a good amp with a serial FX loop on the venue is enough to be able to implement the majority of your personal repertoire without additional equipment, which greatly reduces the workload for the working musician.

A high-quality pedal that deserves to be tested!

TEST: Allan&Heath PA12

 What has always surprised me personally in the music industry is the fact that, despite what is now an incredibly large range of manufacturers and products, the same names are always mentioned as a reference for a product group.

Just as every outsider, for example in the guitar amplifier sector, has to believe that the entire world consists only of Marshall amplifiers, there are also a handful of names in the console sector that appear with great regularity. Is it because they were the first on the scene, because they have the greatest tradition, because the quality is above average or even because of their pretentious appearance? Who knows, maybe it's a mixture of everything.

One of these names is undoubtedly the company Allen & Heath. The British manufacturer looks back on a 30-year history and has developed and sold over 150 different consoles over the years. For testing, I have a product from the PA line, the PA12, a representative of the smaller live consoles, which are particularly characterized by their easy portability.


Construction:

The small mixer comes with a manageable weight of 12 kg and, with its dimensions of 525 mm wide x 145 mm high x 538 mm deep, does not pose any transport problems. However, as with any console, you should always include a case in the economical design, any broken ones Poties and bent faders are guaranteed to ruin your mood before the show.

The workmanship of the device is impeccable, no sharp edges, unclean burrs or poorly screwed sockets. The strong round handle on the base of the mixer proves to be very practical, so you can easily carry the console with one hand without damaging your back. Who doesn't remember the annoying "cramping around" of transporting a 16-channel or more alone when you don't have an official attack surface in the form of handles or recesses.

4 feet on the bottom of the housing and 4 more on the front ensure that the mixer can be easily placed both vertically and horizontally.

The PA12 is an 8-channel mixer plus two stereo channels. The inputs can be assigned either a microphone (XLR) or a line (TRS), with the line input overwriting the XLR input. If necessary, all microphone channels can be connected independently with 48V phantom power using a somewhat fiddly plastic switch.

As expected, below this input section is the insert for compressor operation or a similarly designed dynamic tool. The gain control has an extensive pickup gain range from -63dBu to +5dBu in the microphone and -25dBu to +10 dBu in the line range. The frequencies below 100 Hertz can be reduced using an impact sound filter.

The tone control in the mono channels is divided into two shelving filters (treble 12 kilohertz, bass 60 hertz), a low mid bandpass at 250 hertz and a semi-parametric mid control, which can be tuned from 350 hertz to 7 kilohertz.

The PA12 has a total of four auxiliary sends for monitoring or FX sends. Foldback1 and 2 are pre-fader, but post-EQ routed, AUX is connected after the fader. FX send sends the signal to the internally built-in multi-effects device. All 4 sends can be fed to external devices via corresponding out sockets.

The standard panorama control, a mute switch optically supported by a powerful red LED, a PFL switch and a peak LED round off the overall impression of the channel. The channel strip is completed by a very smooth-running 100 mm fader.

The stereo channels 9/10 and 11/12 can be fed via a total of 4 input pairs, with stereo input 1/3 being a cinch and stereo input 2/4 being a jack. If necessary, the RCA inputs can be fed directly to the stereo sum and thus offer additional returns.

The digital effects processor with 16 programs offers reverb, delay, chorus and other effects, also combined. This effects module feeds the mono & stereo channels via post-fade FX-Aux. The output of the FX module is controlled by a 100 mm fader with mute & PFL and routed to stereo mix and FB1&2 with post-fade level control. At this point, 2 TRS inputs with level control offer an opportunity to combine external FX with the internal unit. The internal FX unit can be switched off to use external effects only. The TRS footswitch jack mutes the FX channel. The effects are MIDI editable using the Allen & Heath software editor.

The output section offers semi-parametric 4-band EQ for the TRS slave outputs. The source selector for the output EQ section can be used for left/right, L&R sum/foldback1, or foldback1/foldback2. On the front of the housing there is the main outs, designed as XLR males along with a 12 volt XLR lamp connection.



Practice:

First of all, the mixer feels “good”. Even control paths, clean and practical alignment, only the faders have too little resistance for me personally. The different color coding of the potentiometer heads may bring tears to some designers' eyes, but it ensures quick and intuitive operation of the controls. After switching on the device, a bright blue (once again, no one uses red anymore ;-)) LED reports the operating status.

No matter how well thought-out the circuitry is on a mixer, ultimately it is the filters that decide whether you win or lose. Allen & Heath in particular, who are considered to be the co-founders of the “British sound” in the console sector, have a duty to prove whether they can also make a mark in the “small car class”.

After leveling the input signal, the treble shelving EQ can first prove itself. He does his job satisfactorily, if a little “stiff”. In direct comparison to a Mackie 12 kilohertz controller, which is much more “silky”, the PA12 comes up short. I personally find it a bit risky to set the bass control at 60 Hertz, as the frequency is very low and is already in the area where you have to fight against the frequency more than you can use it usefully. In my opinion, 70-80 Hertz would have been the better choice, but ultimately this remains a matter of taste. Nevertheless, the controller sounds balanced and is convincing.

I think setting a bandpass at 250 Hertz is very successful, as it allows you to penetrate relatively quickly into “damp areas” and purify them, especially in live operation. The controller does its job tastefully, if somewhat unspectacularly.

But now! If the reader has not yet found the “big bang” of this article, here it comes. The semi-parametric EQ turns out to be the absolute highlight of the channel! You might think it's a different assembly because the color of the filter stands out from the group of four. Here it is, the rough yet soft coloring of the British style, which never destroys the basic alignment or messes up the output signal with internal distortions, even with maximum cut or boost. A very successful approach!



Conclusion:

Committed to tradition. Even a company like Allen & Heath cannot rest on its laurels and must constantly assert itself in the increasingly competitive small mixer segment. With the PA12 they have undoubtedly succeeded.

The console has very extensive routing options and offers practical handling in all areas. In terms of sound, the PA12 manages to generate the traditional “British” sound to a large extent, without foregoing the helpful digital level in the signal routing and effects section. The filters sound good to excellent, the equipment is extensive, and the workmanship is clean.

All in all, a recommendable work tool with a high degree of independence in terms of sound and appearance. If it were still possible to produce this quality at this price outside of China, the impression would be perfect.

TEST: Alesis Transactive Wireless

 If there is one word that has truly achieved worldwide fame in recent years, it is the expression “flexibility”. There is nothing that is more feared these days than a deadlocked construct that cannot adapt to changing circumstances or demonstrate the greatest possible scope of compatibility. Now, what do these introductory words have to do with a review?

Everyone knows the situation where you want to quickly strengthen several components without much effort and, in order to present yourself, you would like to accompany yourself using MP3 from your favorite pad, pod or whatever player. The whole thing is then battery operated and so portable that even the trunk of a Smart car is enough to transport the sound system. Well, the child can be helped.

With the Transactive Wireless, Alesis is bringing a battery-operated speaker system onto the market, which is a helpful tool in terms of amplification for street musicians, small performers and PowerPoint/keynote presentations.


construction

The Alesis TransActive Wireless is a very small and easy-to-transport sound system made in China that works in both mains and battery operation. A rudimentary, three-channel mixer was integrated, which allows a microphone signal to be fed in via a combination socket, a line signal using a separate input and a stereo signal via a mini jack socket. All signals are managed with a master volume controller located on the far right. In addition, the system can play audio files from any device in the form of smartphones or tablet PCs via Bluetooth. The devices can also be charged via a USB port.

According to the manufacturer, the built-in lead-acid battery provides an operating time of approx. 50 hours, with a complete charge of the battery taking approx. 6 hours. There is a cold appliance plug on the side, over which the mains fuse has also been installed. You can also choose between 110 - 120 and 220 - 240 volts in the operating voltage. In addition, three green and one red LED provide information about the charging status of the battery.

The mono system consists of a 1 inch tweeter and an 8 inch woofer, has 25 watts of continuous power and can handle short peaks of 50 watts. Both speakers are protected by a black perforated plate. With dimensions of 290 mm x 380 mm x 440 mm and a weight of 12.9 kilograms, the product actually fits in any trunk and, if necessary, can also fit in the footwell of a small car. The Alesis TransActive Wireless does not have a protective cover; only 8 silver-anodized protective corners offer protection during transport. If you want to improve the system's radiation characteristics, there is also a 35 millimeter speaker flange for a speaker stand on the underside of the housing.

A transport trolley concept is integrated into the product and has a double telescopic rod. To lift the product, there are plastic carrying troughs on each side of the housing. To hold the Bluetooth devices, there is a passive plastic tray on the top of the case, which can handle pretty much any tablet. Even my iPad, which is embedded in the bulky Otterbox, found room in the depression without any problems.

If a device is paired with the Alesis TransActive Wireless System via Bluetooth, a blue LED lights up in the middle of the front panel, provided that you have previously entered the authorization code, as is usual with Bluetooth devices. You can silently disconnect the Bluetooth connection at any time using a tip switch below the LED.

When it comes to operating instructions, the manufacturer seems to only want to target inexperienced users, as the most important steps are roughly outlined on just 3 DIN A5 pages. Admittedly, the lack of sound control on all channels does not allow fine-tuning the sound anyway, but in my opinion a few more practical tips or at least a font larger than 3 millimeters letter height would be appropriate.



Practice

Anyone who looks at the design of the Alesis TransActive Wireless will quickly be clear about the area of application of this tiny device. 25 watts of transistor power rev up an acoustic guitar and also ensure better speech intelligibility in a pedestrian zone, but are not enough to adequately illuminate larger areas acoustically. In addition, there is no real boost to be heard in the deep bass range below 400 Hertz, but this was not to be expected due to the design. What has been solved very nicely, however, is the treble range, which fortunately does not have any excessive highs or angular S and Z sounds.

Electric guitar preamps can also be convincing with an appropriate amp/speaker simulation; in fact, nothing stands in the way of using the rocking solo entertainer accompanied by garage band. If you also own a flat screen or other monitor in addition to an Apple TV, you could even bring in the appropriate video feed via Airplay or iPad / iPhone and generate a real multimedia performance using the simplest means, probably if you have a bright concept.

You should always keep in mind that the missing tone control may have to be managed on the instrument or a preamp. In the case of an acoustic guitar, which today mostly has an active preamp with tone control, this should not be a problem. However, with a microphone, especially since there is no corresponding gain control, the sound is generated exclusively by the microphone type without further processing. It is therefore important to try out whether the individual combination suits your personal taste.

What's interesting is that, although both signals are present on one channel, you can simultaneously play back a signal via Bluetooth and via the Aux-In input. The respective volume must of course be adjusted to the signal sources in advance. A mono signal is generated internally from the stereo signal present without causing disruptive phase cancellations.



Conclusion

With the Alesis TransActive Wireless you are purchasing an extremely compact sound system, which, thanks to its coherent concept, represents the perfect solution for street musicians, solo entertainers and audio presentations. The very good connection to all common Bluetooth devices, including their management, and the extremely easy handling make it possible for even those who don't like technology to achieve good results straight away.

The small dimensions, the universal possible uses and the very long battery life enable the product to be used flexibly and with great practical suitability.

Alesis, a renowned designer and marketer of consumer electronic products, faces competition from several companies in the industry. Here's a detailed look at some of these competitors and their products:

## iSTYLE

iSTYLE is a reseller of electronics¹. While not a direct manufacturer like Alesis, iSTYLE offers a wide range of electronic products, including audio devices. Their product line includes various brands, providing customers with a broad selection to choose from. This extensive range can pose a challenge to Alesis as customers have the opportunity to compare Alesis products with those of other brands in one place.

## AselsanNET

AselsanNET is a company that markets consumer electronics devices¹. Like Alesis, AselsanNET operates in the consumer electronics sector, but it's not clear whether they produce musical instruments or audio equipment similar to Alesis. However, any company marketing consumer electronics could potentially compete with Alesis by offering alternative products.

## Funai

Funai, also known as Funai Electric, is a retail company that sells and markets consumer electronic products¹. Funai's product range includes audio and video equipment, which could serve as alternatives to Alesis products. Funai's strength lies in its established presence in the consumer electronics market and its wide distribution network.

## Distribuidora Santiago

Distribuidora Santiago is a distributor of consumer electronic products. As a distributor, Distribuidora Santiago might offer products that compete with those of Alesis. The company's influence on the market depends on the brands and products it distributes.

TEST: Alesis IO Dock II

 Would Apple ever have dreamed that its iOS series would become a kind of centerpiece, or rather processor power, for an entire armada of hardware devices? One could definitely assume it from the demeanor of Steve Jobs, but I personally believe that even Mr. Turtleneck Sweater himself could have predicted this unexpected boom.

Ultimately, of course, the whole thing makes sense. The new processors in the iPad and iPhone actually release unimagined computing power, although even the best clock speeds cannot hide the fact that when it comes to hardware, the connection options have still not been raised beyond the level of a toy. Selling a seemingly pitiful headphone connection in mini jack format as an audio output and a fiddly Lightning or 30-pin connector as an official interface is simply laughable for a professional musician. It may be that these interfaces are visually appealing and functionally adequate in the IT area, but in the studio or especially on stage, every musician is overcome with cold horror when they see these plastic nuggets.

Knowing this fact, several manufacturers have specialized in reducing iOS devices to their core competence, computing power and optical resolution, and supplying a hardware dock with the necessary connections in the most robust design possible via the main interface. One of these providers is the company Alesis, founded in 1984 by Keith Barr, which achieved world fame thanks to groundbreaking inventions such as the MIDIVERB and the legendary ADAT recording system. With the Alesis iO Dock II, which is now in its second version, the system tries to combine the best of both worlds at a very affordable price.

construction

Let’s start with external values first. With dimensions of 216 mm x 267 mm x 32 mm and a weight of just under 950 grams, the Alesis iO Dock II is the size of an iPad, which is stored in a massive Ottercase. The product, manufactured in China, is made entirely of black plastic, with some parts having a high-gloss finish and others with a matt finish. In order to be able to handle the problem of the different thicknesses of the various iPads from the first to the fourth generation, the Alesis iO Dock II has a thin plastic adapter, which adjusts itself individually to the different thicknesses by folding up a small, centrally attached plastic lock can be adjusted. Simple to implement, but solved in a practical way. When it comes to software flexibility, there shouldn't be any problems either. According to the manufacturer, the Alesis iO Dock II is compatible with almost every Core Audio or Core MIDI app from the Apple App Store.

If you push your iPad into the hardware dock as far as it will go, you have the option of accessing the iPad's interface via an adapter, which is attached to the lower part of the housing using a small cable. Two different adapter heads (Lightning + 30pin connector) are supplied from the factory and can be easily exchanged. Admittedly, visually this cable solution doesn't exactly leave the highly aesthetic impression that Apple generally stands for. In practice, however, a comparatively simple but sensible solution can be created for little money. In addition, with this solution, all previously released iPads, with the exception of the iPad Mini, can actually be integrated into the recording process. It should also be mentioned that, despite the guide rail adapter, the iPad Air is not 100% firmly anchored and can be moved. In my opinion, Alesis will certainly deliver an adapter soon if they don't want to lose connection to the latest iPad generation.

However, it should be mentioned that the iPad is not locked in this dock. This poses a risk of the iPad slipping out of its anchorage and pulling on the cable during transport. I therefore recommend removing the iPad from the dock when not in use to avoid damage during transport. With four glued-on, soft rubber feet, the Alesis iO Dock II had the necessary stability even on smooth surfaces.

Both side parts and the back of the housing are used for the necessary connection of peripherals. In addition to a USB port, MIDI In and MIDI Out sockets are also available on the left, which generates a wide range of control options for all kinds of external peripherals. On the right there is a 6.25 mm stereo headphone jack along with the associated volume control and the sum control for the main output. On the back we start on the far left with the two main outs in jack format. To the right of it there is a direct monitoring switch with which you can monitor the input sources directly without processing the iPad. When it comes to inputs, the Alesis iO Dock II only has two combination sockets, which can be supplied with 48V phantom power via a switch if necessary. This means that high-quality condenser microphones can also be integrated into the recording process.

Both inputs have simple input controls, although input number one can optionally be switched to high-impedance use of guitar signals. This is helpful if you want to use a guitar software plugin, for example in Garageband or similar. However, the extent to which the sonic output of the simulations even comes close to a real guitar setup will not be discussed here. However, I find the freely definable foot switch very helpful, if only to be able to start the recording process with it. Nothing is worse than touchscreen smear when it comes to on-the-fly shooting.

The conclusion is an on/off switch (no longer necessarily standard in this price range) and the connection for the included power supply, which has a lockable strain relief. An avoidably small point, but so important in mobile operations. How many times has this power plug slipped out of the socket, I can't even count it anymore!

Practice

Plugged in and started, new German: plug-and-play, the motto here is that drivers of any kind are not required. First of all, the haptic feel for the iPad changes enormously. The narrow, slightly fragile disc has become a serious wedge, which gives the product stability and better handling. The signal supply via the adapter plug works perfectly, but I am always worried about what could happen if I lose one of the adapters. A possibility to store them in a housing or park them would be a great thing.

In contrast to the first generation, the Alesis iO Dock II no longer has a video output. However, this is compensated for by the Airplay Mirroring function. In collaboration with the Apple TV, for example, you can configure a TV set as an oversized monitor according to your needs.

During normal operation there were no problems with the interaction with various software programs. Whether GarageBand, Cubasis or Auria, all apps ran flawlessly without any problems. It goes without saying that a product in this price category cannot be used as a final DAW for high-end productions, so the sound of the preamplifiers used can be described as appropriate. When it comes to functionality, however, there is absolutely nothing to criticize.

Conclusion

With the Alesis iO Dock II, the American manufacturer continues the success story of the first generation. With a logical concept and practical detailed solutions, Alesis transforms the iPad into an ambitious mobile recording station, which compensates for the iPad's internal interface weaknesses with serious connections and great flexibility in terms of signal flow. Only the lack of two important adapters for the iPad Air and iPad Mini reduces the very good overall impression a little.
