Mix Smarter. Work Faster. Sound Better!

The CQ-20B was designed for life on stage and is the mixer with the highest channel count in the product range. It is controlled via the free CQ MixPad app. CQ takes proven processing and effects devices, adds exciting new supportive mixing tools, and packages it all into Allen & Heath's smallest and most affordable digital mixer series to date.

Fast and Complete - Choose Your Mixing Style

Fast and Complete - Choose Your Mixing Style

Each input channel of the CQ can be switched between two modes.

Quick Channels offer instrument- and application-specific processing with the ability to adjust a full channel’s processing via a single control.

Need more control? Switch to Complete Channels for advanced, in-depth parameter changes.

Gain Assistant - Faster Setup

Setting the right gain level for each channel isn’t the most exciting task, and when you have multiple channels to manage, it quickly eats up your setup time.

The CQ Gain Assistant quickly and accurately sets the optimal gain level for one or more input channels and monitors levels during the performance to avoid unpleasant peaks or surprises.

Gain Assistant - Faster Setup
Feedback Assistant - Say Goodbye to Feedback

Feedback Assistant - Say Goodbye to Feedback

The CQ Feedback Assistant automatically detects and eliminates problematic frequencies with up to 16 filters per output, so you can mix with confidence—and forget about feedback.

Pure Sound - You Won't Believe Your Ears

CQ uses the technology of the latest generation of live sound consoles to deliver audio quality previously unimaginable in this price range. Pure 96 kHz audio is combined with integrated studio-quality processing and an optimized effects suite to set a new standard for what ultra-compact digital mixers can do.

Built-In Effects - A New Breed of Effects

CQ introduces a new range of high-quality, user-friendly reverb, delay, and modulation algorithms with instrument-specific presets for quick setup.

Selected devices feature the new FX Assist tool, which automatically shapes effects and dynamically responds to your input signal to ensure your mix is enhanced, not overwhelmed, by effects.

User-Friendly - You Always Have Control

Although the CQ-20B is designed for life on stage, you can mix from anywhere in the venue via the free CQ MixPad app and built-in dual-band Wi-Fi.

With CQ MixPad, you have control over all mixer parameters, allowing you to soundcheck, mix, and record from your mobile device or computer.

We replaced our old Dynacord power mixer - it was simply too big, too heavy and impractical for live use. We were looking for a digital mixer that was powerful, affordable and easy to transport. We also wanted to be able to record our rehearsals and performances in good quality. The CQ-18T fulfills all these requirements without any problems.

The operation is well thought out and intuitive - anyone who works with a DAW will find their way around immediately. The price-performance ratio is convincing, we don't miss any essential functions. The only downside is that it is not possible to loop in external effects directly, but only via detours.

Conclusion: For our four-piece band (drums, bass, guitar, two vocals and backing tracks), the mixer is absolutely sufficient and practical.
Excellent sounding console.

Admittedly: The operation is somewhat cumbersome when it comes to navigating through the various "layers" of the menus. However, the free definition of the 3 "hotkeys" and the 3 rotary encoders makes life on stage much easier. But the biggest plus point, and for me the decisive one: This console sounds absolutely outstanding! And for that reason alone it will remain in my inventory. I can't say anything about the "Easy" functions, because I never use "presets" but make my Chanel settings by hand. This could be a plus point for inexperienced technicians / musicians.
