Mix and record with the Allen & Heath CQ-20B, an ultracompact digital mixer in a rackmount/stagebox configuration featuring 96 kHz FPGA processing, Bluetooth, wireless control via built-in Wi-Fi, and SD/USB audio recording and playback. The mixer is well suited for bands, producers, and AV rental houses, and can be used as a main mixer in a small venue or a sub mixer on a larger stage. This unique format has no screen and is designed to be used with a compatible tablet. Keep it onstage and mix wirelessly from anywhere in the room.

The free CQ-MixPad application is easy to navigate and control the robust mix engine that comes complete with several assistants to help your mixes sound their best including a gain assistant, feedback assistant, FX assist engine, and Automatic Mic Mixer (AMM). Take control of the full complement of channel strip effects like EQ, compression, and gating that's available on every channel and set up several sub mixes for monitoring and effects. The CQ-20B features 16 mic/line XLR/combo XLR-1/4" inputs and two pairs of balanced 1/4" TRS line inputs. For outputs, the mixer offers two main XLR connectors, two 1/4" alternate connectors, and six XLR mix connectors. There is also an assignable headphone output. The mixer ships with a standard IEC power cord.
