Studio downsizing sale. Drawmer is a UK company that only makes high-end gear. This monitor controller sounds fantastic, but my new rig has a built in monitor controller, so I'm moving it along. Connect up to three sources and three pairs of monitor. Left & Right speaker cuts, Mute, Phase reverse, mono and dim switches. It has two, powerful headphone amps with talkback and a talkback level. The Volume knob is massive and smooth. What's more, each output has a trim calibration on the top of the unit so that, using a dB meter, you can guarantee the same volume when switching speakers. It's a desktop unit, but I'm including the rack kit for a 19" rack. This brings the 1/8" auxilliary input jack to the front for easy access. I can't say enough about how great this switcher is.
