The 4-channel monster
Archyx 18.08.2019
tl;dr : The speaker output wiring is a bit quirky. Lots of gain, possibly not good for sensitive speakers in a smaller room.

I bought this amplifier to have a single amplifier unit to drive a bi-amped passive 2-way speaker setup. The amplifier was driven by a dbx DriveRack PA² (EQ, crossover, driver alignment delay). The only drawback in this application was excessive amplifier gain for the little Black Pearls, since this particular audio setup was not to be played loud. However, another pair of speakers (Radiotehnika S-400 4-way monsters) were perfect to be driven by this amp with both amplifier pairs in bridge mode.

The blowers are audible in a quiet room, but then again, this amp is most likely intended to make the speakers loud before the fans really spin up. Another nice thing is that the automagic stand-by function can be switched off.

It's heavy, too. The case design is such that the amp can be set down on an even hard surface on any of its sides without damage to controls or connectors. Gain controls feel good with a little dampening and have detents.

ATTENTION! Since the observation below is not documented in the manuals, please check the output wiring of your amp before connecting any speakers with any methods not described in the manual! There may be changes between board revisions as products are improved!

So far the only inconsistency between the user manual and the actual device I got is the speaker output connectors. The pairs in them are not connected in parallel as the manual loosely suggests, but are connected so that the second pair (2+, 2-) on ch 1 output matches the first pair (1+, 1-) of ch 2 output. The second pair of ch 2 is left open. (This is actually what I was initially expecting this kind of amp to have!)

This means that you don't need a silly Y-cable for connecting a speaker to a bridged amp as specified in the manual, but connecting the 1+ and 2+ contacts of an odd-numbered speaker output to the speaker's + and - does the trick. Also bi-amping a speaker with dual inputs is easy with just one NL4 SpeakON plug carrying both pairs out of the amplifier.

The same applies to the 3-4 channel pair with the exception that on the ch 3 output connector 2- is connected to 2+ instead of the ground with the other 1- and 2- contacts. This means that both grounds (or "negatives") for bi-amping on ch 3 need to be connected together to 1- instead.

The performance for such a low price tag is great, but you can expect some little quirks like this to come with it.

Perfect
Sabalys 21.05.2020
Perfect amp for small bar sound system! Fair price and quality ratio! Sounds great for background music with t.box CL 108 speakers in 60sq.meters area! Great feature is auto turn off so when bar closes you don't need to worry about your sound system, because it turns off automatically and saves electricity power. Also great feature is 4 channels in only 2 Units rack space. Recommend for similar instalations!

The fans are louder than I had anticipated – but I guess I should have known that, so that is probably on me.
However, the amp I received added distortion to all channels (as was apparent by feeding it with a simple 440 sinusoid, and comparing it with other amplifiers, same monitors). I assume this was a flaw in my specific amplifier; in any case I have just returned it and decided to move towards the MK II models (with no fans).
Thomann was perfect, as usual, with customer care and return policy.

Have installed 2 of these to replace Lab Gruppens and fund the performance to be similar. Very reliable
