Bought this a few weeks ago and on plugging into my studio the PSU had a terrible buzzing sound. Spoke with Thomann and they sent out replacement PSU which arrived today. Great service from Thomann!
I bought this mixer because of the 3 master outs and what is essentially 11 channels (5 mixable). The mixer will be used for various bits of audio equipment (Kontrol S8, CD, DAT, Tape, Reel to Reel etc.), Initial setup to get things working and I'm very happy with the purchase, does exactly what I need and the 3 master outs is more than enough for my setup.
Decent build quality, not pushed it yet, but I doubt it will have any problems. Good price, cheap, but doesn't feel like it.
Would recommend buying to anyone in the market for this kind of mixer.
