Allen & Heath Qu-SB Digital Mixer

The Qu-SB is Allen & Heath's compact, rackmountable digital mixer engine, an 18-in/14-out core that starts at 16 mono and 1 stereo input and expands to 32 mono / 3 stereo with Allen & Heath remote expanders, driven from an iPad or laptop rather than a physical fader surface.

It outputs 4 mono mixes, 3 stereo mixes and LR (expanding to 4 mono / 7 stereo / LR), plus a 2-stereo matrix, and a 32x32 USB audio interface covers multitrack recording and playback. Every channel carries the same processing and FX as the rest of the Qu range.
