The Allen & Heath CQ-20B is a 20-channel rackmount/stagebox digital mixer optimized for live performance, recording, and portable audio applications. As the highest channel-count model in the CQ series, it leverages a 96 kHz FPGA processing engine for pristine audio quality, combined with smart assistive tools, built-in effects, and seamless wireless control via the free CQ MixPad app. Designed for bands, producers, small venues, conferences, and AV rentals, the CQ-20B serves as a main mixer for compact setups or a sub-mixer in larger systems, offering 24x24 USB/SD multitrack recording, Bluetooth playback, and integrated dual-band Wi-Fi for app-based mixing from anywhere in the venue—no external router required.
