This mixer excels in 2 areas, it has a superior pro mixer sound via the high end Burr Brown mic pre's and it's also amazingly compact for the features. You can use it as an 8 channel DI, A passive summing mixer, or a field mixer in an 8 x 2 format.

Not quite perfect mixer

By Do-Don

from Nashville TN

I have used this mixer for more than a year on the road. I use it as a line mixer for a midi guitar to mix a Roland VG99 with Roland synth XV 2020 and other synths. I also have a Fishman Aura plugged into one of the 8 mic inputs. The sound is very good and the features are usable. However, it is disappointing that the main outs are TRS and not XLR. The out put is down 20db making it hard to get enough level to the house and monitor console. Lately the power supply, (which has a very flimsy connecter) has taken to buzzing very loud in the rack its in. If I hold the supply the buzzing stops. It is now getting into the PA and I will have to stop using it. I like the mixer and the way it sounds but these little things are getting bigger.
