Allen & Heath - CQ-20B

Ultra-Compact 20in / 8out Digital Mixer with Wi-Fi
Discover the superb functionality of the Allen & Heath CQ-20B, an ultra-compact digital mixer designed in a rackmount/stagebox format. With cutting-edge features like 96 kHz FPGA processing, Bluetooth connectivity, wireless control via integrated Wi-Fi, and versatile SD/USB audio recording and playback, this mixer is a must-have for bands, producers, and AV rental services. It seamlessly transitions between roles, functioning as a main mixer in smaller venues or as a sub mixer on grander stages.
What sets the CQ-20B apart is its unique design. Operating without a screen, it's meant to be used alongside a compatible tablet. This means you can keep it conveniently onstage and control it wirelessly from anywhere within the venue.
Navigating the mixer's powerful mix engine is made easy with the intuitive CQ-MixPad application, available for free. This app puts you in command, assisted by a range of features to enhance your mixes. From the gain assistant and feedback assistant to the FX assist engine and the advanced Automatic Mic Mixer (AMM), your audio will be finely tuned.
Each channel also comes equipped with a comprehensive selection of channel strip effects, including EQ, compression, and gating. The CQ-20B offers ample inputs, featuring 16 mic/line XLR/combo XLR-1/4" inputs and two pairs of balanced 1/4" TRS line inputs. For outputs, it provides two main XLR connectors, two 1/4" alternate connectors, and six XLR mix connectors. Additionally, there's a headphone output that can be assigned for various purposes. Worried about setup? No need - the mixer comes with a standard IEC power cord, ensuring a smooth start to your audio journey.

Mix Smarter. Work Faster. Sound Better.
CQ takes Allen & Heath's renowned processing and effects, adds exciting new assistive mixing tools, and packages it all up into their smallest, and most affordable, digital mixer series yet.

Pick Your Mixing StyleEvery input channel on CQ can be switched between two modes. Quick Channels offer instrument and application specific processing with the ability to dial in a full channel of processing via a single knob. Need more control? Switch to Complete Channels for advanced, in-depth tweaking of parameters.

Faster SetupsSetting the correct amount of gain for each channel isn’t the most exciting task, and it quickly eats into your setup time with multiple channels to take care of. CQ’s Gain Assistant quickly and accurately sets the optimal gain level for one or multiple input channels and continues to monitor levels during the performance to prevent any nasty peaks or surprises.

Say Goodbye to FeedbackCQ’s Feedback Assistant automatically detects and eliminates problem frequencies using up to 16 filters per output so you can mix with confidence – and forget about feedback.
A New Breed of Effects

Built-In FXCQ introduces a new suite of high-quality, user-friendly reverb, delay and modulation algorithms with instrument-specific presets for speedy setup. Selected units feature our new FX Assist tool, automatically shaping the effects and dynamically responding to your input signal to ensure your mix is enhanced by FX, not engulfed.
You’re Always In Control

User FriendlyAlthough the CQ-20B is designed for life on the stage, you’re free to mix from anywhere in the venue via the free CQ MixPad app and the integrated dual-band Wi-Fi. CQ MixPad gives you control over all parameters of the mixer so you can soundcheck, mix and record from your mobile device or computer.
