Mix Smarter. Work Faster. Sound Better.

CQ takes our renowned processing and effects, adds exciting new assistive mixing tools, and packages it all up into our smallest, and most affordable, digital mixer series yet.

Quick and Complete

Pick Your Mixing Style

Every 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.


Gain Assistant

Faster Setups

Setting 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 your one or multiple channels and continues to monitor levels during the performance to prevent any nasty peaks or surprises.


Feedback Assistant

Say Goodbye to Feedback

CQ’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.


Built-In FX

A New Breed of Effects

CQ 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.

User Friendly

You’re Always In Control

Although 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.


Integrated Wi-Fi

Leave Your Access Point at Home

The CQ-20B is designed to be controlled via the intuitive CQ MixPad app and features powerful integrated dual-band Wi-Fi so you don’t need to connect an access point or router to use apps for control of the mixer.

Just connect your devices to the CQ’s secure Wi-Fi network and you’re ready to go.


Get Yourself Connected

CQ-20B gives you all the connectivity you need to get going with 16 mic/line inputs plus two stereo line inputs.

When it comes to outputs, there’s a pair of main mix outputs plus 6 outputs for monitor mixes – enough for the whole band – and an assignable Alt Output is also provided.



Simplify Speech

The integrated Automatic Mic Mixer (AMM) means you can instantly reduce background noise and improve clarity for speech applications without lifting a finger.

AMM is available on all CQs input channels, making it the perfect portable mixer for conferences, podcasts, debates and small-scale theatre productions.
