Designed for life on the stage, CQ-20B is the highest channel-count mixer in the CQ range and is controlled via the free CQ MixPad app with integrated dual-band Wi-Fi — no router or access point required. CQ takes Allen & Heath's renowned processing and effects, adds exciting new assistive mixing tools, and packages it all into the smallest, most affordable digital mixer series yet. Mix smarter. Work faster. Sound better. 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 every parameter. Gain Assistant Faster Setups Setting the correct gain for each channel isn't the most exciting task, and it quickly eats into setup time with multiple channels to manage. CQ's Gain Assistant quickly and accurately sets the optimal gain level for one or multiple input channels simultaneously. It then 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 entirely. Sound Quality You Won't Believe Your Ears CQ draws on technology from Allen & Heath's latest generation of live sound consoles to deliver audio quality previously unimaginable at this level of mixer. Pristine 96kHz audio is partnered with studio-grade onboard processing and an optimised suite of FX to set a new standard for what's possible with ultra-compact digital mixers. Built-In FX World-Class Effects A new suite of high-quality reverb, delay and modulation algorithms with instrument-specific presets for speedy setup. The FX Assist tool automatically shapes effects and dynamically responds to your input signal — enhancing your mix, not engulfing it. Control DCA & Mute Groups 4 DCAs each control the level of any combination of inputs, outputs and FX for single-fader control of multiple channels. 4 Mute Groups let you mute and unmute multiple channels at once — perfect for muting a whole band between songs. User Friendly Intuitive Control The 7" touchscreen and rotary control make it simple to set up and get mixing. App-controlled via CQ MixPad (no physical faders) give instant access to commonly used functions at the push of a button. Connect a router or access point and the free CQ MixPad app gives full control of your mix from anywhere in the venue on iOS, Android, Windows or macOS. CQ MixPad Full remote control of the CQ-12T from a tablet or phone. Access all mixing functions, scenes and settings from anywhere in the venue on iOS, Android, Windows and macOS. CQ4You Personal monitor mixing app for musicians. Performers take control of their own in-ear or wedge mix independently from the front-of-house engineer. Integrated Wi-Fi No Router Required The CQ-20B features powerful built-in dual-band 2.4GHz/5GHz AC Wi-Fi with automatic channel selection. Simply connect your devices directly to the CQ's secure Wi-Fi network — no external access point or router needed.
