The home studio is becoming my daughter’s bedroom. I’ve accumulated a lot of nice things & they have to go. I’ve taken great care of everything piece.
This Allen & Heath digital mixer was used in band practice with an IEM system, and it never left the studio. Works like new… though I did not keep the box, I am throwing in the separate rack-mount ears ($99) I purchased for the mixer–no charge.
Here’s a bit of info from Sweetwater:
Its Preamp Gain Assistant takes all the guesswork out of setting your levels. Its Feedback Assistant makes locating and neutralizing acoustic feedback frequencies a piece of cake. You also get instrument-based Quick inputs that help you get a great sound — fast. The CQ-20B includes four Smart-FX engines, which enable you to select from easy-to-use reverb, delay, and modulation units for instrument-centric, signal-conscious effects.
