The CQ is super portable and easy to use, but still a fully featured digital mixer, suitable for technical and nontechnical users. This fully featured mixer can fit in a backpack (or soft case) and delivers uncompromised audio quality, smart controls and smart processing tools so you don’t need to be an expert engineer to sound amazing. A ‘Preamp Gain Assistant and Feedback Assistant allow for a faster setup, while instrument-based quick inputs get you to a great mix faster than ever. A unique combinations of tactile encoders, custom keys and a remote control stagebox offer multiple mixing interface options. The CQ-20B can be used as an interface, to record live shows or rehearsals, for virtual soundchecks or mix right out of the box.
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.
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.
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.
You Won’t Believe Your Ears
CQ draws on technology from our 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.
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.
