Allen & Heath CQ-20B Digital Mixer With Wi-Fi and Bluetooth

The Allen & Heath CQ-20B is an ultra-compact, stagebox-style digital mixer designed for modern live sound, rehearsal spaces, houses of worship, and mobile recording setups. Built on a high-resolution 96kHz audio platform, the CQ-20B delivers pristine sound quality while offering smart, assistive tools that make setup and mixing fast and intuitive for engineers of any experience level.

Unlike traditional mixers, the CQ-20B is fully controlled via a Wi-Fi–enabled tablet (sold separately), giving you the freedom to walk the room, adjust monitors on stage, or fine-tune front-of-house sound from anywhere in the venue. Compact, lightweight, and rackmountable, it fits easily into a backpack or small rack while providing the power and flexibility of a full digital console.

Wireless Control and Stagebox Design

The CQ-20B is designed to live on stage or in a rack, with all mixing performed wirelessly from your tablet. Built-in dual-band Wi-Fi (2.4GHz and 5GHz) ensures reliable control across a range of environments, whether you need extended range or maximum stability. This design eliminates the need for a bulky front-of-house console, making it ideal for bands, engineers, and venues that value portability and clean stage layouts.

Smart Mixing Tools for Faster Setup

Allen & Heath’s intelligent processing tools make the CQ-20B fast to deploy and easy to manage. The Preamp Gain Assistant automatically sets optimal gain levels for microphones and line inputs, while the Feedback Assistant actively detects and suppresses problem frequencies to prevent feedback during live performances. Instrument-based Quick Inputs allow fast setup with minimal adjustment, while Complete Inputs unlock full parameter control for advanced users who want deep customization.

Powerful I/O and Recording Options

Despite its compact size, the CQ-20B offers generous connectivity. It features 16 mic or line inputs, including eight XLR and eight XLR/¼" combo inputs, with two Hi-Z inputs for guitars and basses. Two stereo TRS line inputs handle keyboards or playback sources. For recording and playback, the CQ-20B provides a 24x24 USB audio interface and 24x24 SD card recording, making it easy to capture live shows, rehearsals, or multitrack sessions without external gear. Bluetooth stereo input allows quick playback of reference tracks or intermission music.

Flexible Outputs for Any Live Setup

On the output side, the CQ-20B includes six TRS mix outputs, a pair of XLR main outputs, two assignable ¼" outputs, and a dedicated headphone output for monitoring. A footswitch input supports hands-free control, while Ethernet connectivity enables wired network control if needed. The fold-down Wi-Fi antenna protects the hardware during transport and setup.

A Compact Mixer for Live, Studio, and Hybrid Use

The Allen & Heath CQ-20B is an ideal solution for gigging musicians, live sound engineers, AV professionals, and content creators who need powerful mixing capabilities in a small, portable format. Whether used for front-of-house mixing, monitor control, virtual soundchecks, recording, or streaming, the CQ-20B delivers professional sound quality, flexible routing, and intuitive control wherever you work.
