The GL2200 is a four-bus mixer available in 12, 16, 24 and 32 channel configurations. As a dual function console, the GL2200 is intended for front-of-house, monitoring, recording and combined applications for PA companies, bands, theatres, clubs and houses of worship.

The new model is based on the popular GL2000 design, with a number of extra features added as a result of requests by users in the field. Among the GL2200's enhancements are channel direct outputs for multitrack recording capability, mute switching on the groups, stereo returns and main outs, a 12V lamp connector and an updated power supply with built-in combiner for backup or remote DC supply. Allen & Heath has also added an "engineer's toolbox", comprising a built-in 1kHz sine oscillator for equipment lineup, a pink noise generator for speaker calibration and full talkback routing.

The GL2200's mic/line inputs have individually-selected phantom power, four-band, semi parametric EQ with hi-pass filter and in/out switching, six auxes on individual controls, four-segment LED metering and 100mm faders. Two fully featured stereo inputs and two stereo FX returns are included on each frame size, effectively adding eight extra inputs.

The console has a robust metal frame, steel nuts on all pots and individual, vertically-mounted circuit boards for ease of service and long life.
