TEST: Mackie Hotwire V12

 Musicians have the unpleasant trait of always wanting to have everything at once. On the one hand, they want to sell tons of records to the ignorant mob and have easy ladies with dubious reputations whisper little nonsense in their ears, but on the other hand, it's time to cry when they only serve as a projection surface for unfulfilled dreams and not because of them musical achievements are revered.

Interestingly, a similar approach can also be found in the instrument sector; in no other genre is the term “jack of all trades” used as often as in the wide world of the six-string musical group. But here too, there's always the same complaining and complaining from the artists' corner about "it sounds distorted but it's shit", "it's way too heavy", "can you amplify an acoustic guitar over it, no...?" , "the speaker emulation sounds musty", "AC/DC used to sing through guitar amplifiers in the rehearsal room" and so on, and so on...

But what if a manufacturer actually managed to design the Swiss army knife for the amplifier and covered almost all areas of the instrumentation to be amplified? Skeptical? Me too, for example the speaker approach alone is diametrically different between the amplification of an acoustic and an electric guitar.

Nevertheless, the console and loudspeaker specialist Mackie sets out to make the impossible possible and presents an approach that has it all with the Hotwire VT12, designed by Greg Mackie.



Construction:

OK, let's first take a look at what amplifying equipment is in an average rehearsal room:

1.) Electric guitar (clean and distorted sounds, under no circumstances should it be operated with a tweeter, otherwise the increasing distortion sounds like a mixture of a razor and a chainsaw)

2.) Acoustic guitar with pickup (only clean sounds, definitely needs a tweeter, as the regular 12 or 10 inch electric guitar speaker stops at 4-5 KHz at the latest and does not transmit enough treble)

3.) Vocal microphone (description like acoustic guitar with pickup)

4.) Keyboard (you can still use an electric guitar amplifier for a distorted pig organ in Deep Purple style, but with a piano or synthesizer you need a tweeter and the most neutral sound direction possible, since the filters of a guitar amplifier are based on completely the wrong frequencies)

5.) MP3 player/sequencer (usually requires a vocal system or P.A., tweeter is mandatory)

All in all, a wild mix, of which positions 2-5 are usually sent via the local vocal system (I hate it when the keyboard players take over a monitor route just because they don't use their own backline...)

The Hotwire VT12 now comes with an independent design, which activates/deactivates a tweeter depending on the area of use, or optimizes the sound control and other parameters for the respective area of use with massive use of a processor.

With dimensions of 43.2 cm x 25.4 cm x 46.4 cm (H x D x W) and a weight of only 11.4 kg with a maximum output of 120 watts, the combo is extremely handy and comparatively light. When you see the little guy from the front or above for the first time, you are initially quite impressed by the visually appealing panel design, but you are still reminded of a more or less well-known electric guitar combo concept.

The big “Oha” effect is only revealed on the back of the combo, where a volume-adjustable XLR input labeled “Mic Input” quickly shows that this is not a new edition of a well-known principle. To make a long story short, the Hotwire VT12 claims to be able to amplify all of the points 1-5 mentioned above in good to very good quality.

At this point at the latest I am aware that the purist faction will shake their heads and treat the rest of the review with great reluctance, if not even disregard, since one can, if necessary, write immense treatises using a loudspeaker. How is something so opposite like a microphone and a distorted electric guitar supposed to share a signal path in intimate harmony without attacking each other tonally in the worst possible way?

The solution lies in the use of modern processor technology, which calculates the optimal parameter design for the respective application. For example, the built-in 30 watt tweeter is muted when using electric guitar presets, while it is activated when using an acoustic guitar.

Conceptually, the focus of the amplifier is on the electric guitar. Most of the factory sounds were designed for this area of application, whereby the Hotwire does not try to copy the protagonists of amplifier construction as faithfully as possible to the original, as VOX does with its Valvetronix series, but rather it takes key points of the respective amplifier sound design and adds them into a stylistically clear assignment.

The Hotwire has a total of 24 banks with four memory locations each, half of which can be overwritten with your own sounds. In order to ensure an appropriate preamplifier, 2 type 12AX7A tubes were integrated into the emulation area, which are intended to ensure sufficient warmth in the sound image, especially with distorted sounds.

The different presets are used to simulate different amps and cabinets, as well as to generate a rich selection of dynamic, modulation and spatial effects, all of which are visually supported by a very bright display.
The final volume is set using the Output Power step switch, which works in 3db steps, which corresponds to doubling or halving the volume. In addition, the combo has built-in little helpers for everyday use, such as an extensive metronome, a strobot tuner, a loop recorder and noise/buzz suppression.

In addition to the microphone input, there are a lot of other ins and outs on the back, such as the connection of the optional foot pedal, a USB port to reconfigure the sounds in the PC, the connection of an external speaker (4 ohm minimum), an adjustable headphone out, two symmetrical ones XLR L/R outs for direct connection to mixers etc., an adjustable line stereo input for connecting an MP3 player or similar and a balanced/unbalanced insert loop.

But oops, pretty much any sound source has actually been thought of here!


Practice:

Nice, nice, the connection options are really convincing, but what does the whole thing sound like, the first impatient people will ask, after all, that's exactly what causes the biggest frowns when it comes to the same construction.

I made it very easy for myself and actually just went through the electric guitar presets and I have to certify that the Hotwire is extremely practical. In the 48 different sounds you will find a round compilation of all common sounds including the associated FX components, all of which can of course be post-processed in every parameter. Once you start editing the various parameters, your head will start to spin after a short while, as the conceptual variety of sounds will almost overwhelm you.

The Cabinet Swich alone radically changes the basic tone of each preset and you haven't even touched the other controls yet! So if you want to go to the trouble of editing, you shouldn't do anything for a weekend, the time will fly by.

The use of the acoustic guitar and microphone also shows a very practical use, although it has slightly fewer processing options. Plug it in, adjust it briefly, get started, it's rarely been so easy to use the different instruments via an E-GUITAR COMBO! to reinforce.


Conclusion:

If anyone is wondering why the practical article written above is so short, the answer is self-explanatory. The Hotwire has such an extensive sound design that any rudimentary list does not do the device justice and a detailed list would go beyond any test scope.

The areas of application for the amp are almost endless. Any musician who, for example, plays in a cover band in which they have to pick up an acoustic guitar from time to time will love this amp, finally no more annoying use of the monitor system as a backline replacement. Keyboard player has no backline (again)? Give him the hotwire! The singer needs a simple amp for the rehearsal? Let him take the hotwire! He also wants to play guitar on a few songs? No problem. Would you like to play along to your own backing track at a party and maybe even sing, so loudly that the neighbors call the police? Nothing easier than that and so on and so forth...

Personally, I currently... There is no amplifier known that offers such immense versatility and masters the sometimes extremely difficult parameters so well in terms of sound. If you want to find a point of criticism at all, you can only attest that the Hotwire has a relatively low-pitched and muffled basic sound, which you can get under control with appropriate editing.

Yes, he has a flaw! The carrying handle of the combo smells really bad, the solvents probably still have to find their way out.

Otherwise, all respect, a conceptual masterpiece!
