A complete mixer that fits in a backpack.
The Allen & Heath CQ-20B digital mixer is built on a 96 kHz platform with intelligent processing and a wide range of connectivity options: network, Bluetooth, wireless, SD, and USB. The CQ is super portable and easy to use, yet remains a complete digital mixer, ideal for both technical and non-technical users. This all-in-one mixer fits in a backpack (or soft case) and offers exceptional audio quality, intelligent controls, and smart processing tools, so you don’t need to be a seasoned engineer to achieve amazing sound. A preamp gain assistant and feedback assistant allow for faster setup, while quick instrument-based inputs let you achieve a great mix faster than ever. A unique combination of touch encoders, customizable keys, and a stage remote provides multiple mixing interface options. The CQ-20B can be used as an interface for recording live gigs or rehearsals, for virtual soundchecks, or for mixing right out of the box.
