Installation in small church
Johnf52, 21.03.2014
Installed along with a pair of Evid 4.2's and A&H ZED14 desk.
Nice unit. Has very rugged feel for its cost. Effective array of input and output options, though I used the conventional xlr in and speakon out format.

For this price, nice to see it comes with built in limiters etc, though in this particular application should not be necessary. Nice clean sound at low and high levels with no perceptible coloration. Also nice are the protection relays, seldom found in units at this price.

Among the features on this unit is the "standby switch off when no, or v.low level input. For this install, had to switch this feature off, which is easy to do with slide switch above mains in. Perhaps would be nice if the features switches did not use letters or initials but plain English or somewhere (plenty of room on the back panel) there was an interpretation of the code to save looking it up in the hand book!

On the whole Thomann great amp, but PLEASE supply UK with UK mains plugs as "technically" it is now against UK regulations to chop off a German fitting and replace with a 13A plug unless you are a qualified "sparky"

Very awesome product!
Dan.D, 06.10.2017
This is my first Thomann product, and I have to say it's a really great product. I use it for small parties in a medium sided room with a lounge area outside, and it fills up both areas effortlessly. Never disappointed.

The physical build quality is very good - it's very sturdy and it's made of good material. The sound quality is also impressive, especially when considering it's low price tag. It produces quite crisp sound while delivering plenty of bass.

The only issue I had is that it does not fully support mono mode. I would have used this to power one speaker (to hear both left and right channels from one speaker), however when connecting the speaker in bridged mode it only outputs sound from the source's left input channel. However that's a lack from my side as this is something that I should have researched about before, so it's not something that I can complain about. If you don't need this feature than I recommend it.

Very happy with the sound quality it delivers!

Good choice for this price range
Azazello, 27.05.2018
I'm using this to drive hifi speakers at home.
CONS: this unit was clearly conceived to be used in PA applications. It fits in 2 rack units, has separate volume controls for the two channels and no other controls on the front panel. It has a vent which is relatively quiet for its intended purpose, but extremely noisy for home or studio applications.
PROS: while lacking in controls, the unit has many configurable options on its back panel, including input sensitivity, a ground/lift switch, an automatic standby option and very good connectivity. The vent can also be easily disconnected with almost no risk, for low power usage (ie driving small hifi or studio speakers.

I'm using this to drive two Mission LX-2 monitors. I wouldn't recommend it for serious studio applications, but it does serve its purpose extremely well for its price and while I'd rather use a more high-end amp I can definitely see myself mixing on this configurations no less than I do on monitors in a mush higher price range (Yamaha HS series, Adam F series and so on).

Plus, the unity looks rather well built to me.

Good Amp, Shame it has such a bad earth :(
17.11.2015
Was using this amp originally to drive tweeters in bi-amped hi-mid cabs, but this amp picks up even the slightest thomann earth interface! And makes a huge pop when turning the unit on or off with the dials up or midway, to a point that it blew all four tweeters! Also the heating in the venue we use it in has a thermostat with a relay and the amp thomann pops every time the heating turns on and off! It might be a fault with the amp I brought maybe? Plus I have the older version of the amp. But if using on some cheap 10 inch full range cabs its alright and has a nice but of thomann power behind it, even though its 120w a side, it sounds a lot more! Shame it has these small faults. It now justs sits in the rack as an emergency amp if all fails!
