I use this in a portable rig together with a QSC K12. The sweepable mids have become an essential tool for me for cleaning up any mud. However, the knobs can be quite fragile and come off.
The built quality is impressive. Great functionality for such a small mixer. Mixers are never perfect, but this one is getting close. I love, that I can listen into each track before mixing it in. Not many small PA mixers have this feature. The FX I use, sound really good, too. Low noise floor, also.
