Wireless controllable digital mixer from smartphone, tablet or computer

The CQ digital mixer series is based on 96kHz FPGA processing technology, with a variable bit rate up to 96bit, capable of operating at an extremely low latency, less than one millisecond: <0.7ms. The CQ-20B mixer has been designed for use wherever high-quality audio processing and summing are required. It can be used by bands, sound engineers, service providers, in rehearsal rooms, as a main mixer in a small club, theatre, bar or as an on-stage mixer. The CQ mixer series features next-generation tools and effects for better, simpler and faster mixing. There are 4 effect processors (send/return) called FX Assist integrated into the CQ-20B that provide various reverb, delay, chorus, ADT, flanger, phaser and various modulation algorithms, with specific presets for instruments and sound sources. These automatically and dynamically adapt to the processed signal. On the input channels, we can count on two distinct processing modes: the new and simplified “Quick” mode, which provides a one-knob style processor for each type of instrument capable of managing a macro of parameters, and the “Complete” mode with all the individual parameters and processors that we are used to finding on a digital mixer channel. Each channel can be configured independently, and you can switch from "Quick" to "Complete" mode at any time. The Gain Assistant function saves us time by automatically and accurately applying the correct gain value to the preamplifiers, monitoring the situation as needed to compensate - if necessary - for the input level. It should also be noted that the value of the preamplifier gain parameter, being digitally controlled, will be stored in the scene, and can therefore be recalled when the scene is reopened. The Feedback Assistant is available on each output to identify, filter and therefore correct any feedback and unwanted re-entries. It can be used in simple "single button" mode, or configured in detail via more in-depth controls (up to 16 filters). The AMM - Automatic Mic Mixer is present on all input channels to help immediately improve voice intelligibility while also reducing background noise.

This mixer offers 20 analog inputs: 16 mono mic/line and 2 stereo line (2x L and R ¼” TRS jacks). The 16 mic/line inputs are divided into 8 on Combo connectors (Jack/XLR) and 8 on XLR. A total of 20 channels (16 mono and 4 stereo) considering the two digital stereo inputs Bluetooth and USB A (for audio playback from pen drives). In addition to the stereo Main Out on (L/R) XLR connectors, the Allen & Heath CQ-20B provides 6 Aux Monitor outputs on XLR connectors, an Alt Out (L/R) on ¼” TRS jack and a headphone output. For network connection, there is both an RJ45 socket and integrated Dual Band Wireless for direct app control.

With the Allen & Heath CQ-20B you have the freedom to record and playback in multitrack up to 24 In and 24 Out on an SD Card inserted in the dedicated slot on the panel, or on PC and MAC computers using the integrated USB audio interface (type B port). The maximum recording limit on SD Card is regulated by the supported formatting standard which is FAT32, which for a multitrack recording at 48kHz is about 8 hours; 4 hours are supported for multitrack recordings at 96kHz. This corresponds to about 72GB of occupied space. NB: Class 10, UHS speed class 1 SD Cards, not less than 10MB/s, are recommended.

Control the mixer from your computer, smartphone or tablet thanks to the two free applications for Windows, Mac, Android and iOS operating systems. CQ-MixPad gives you complete control over your Allen & Heath CQ mixer, while with CQ4You each musician, singer or performer can adjust their own mix.

You can rackmount your CQ-20B mixer using the dedicated CQ20B RK19 kit (Algam EKO code: GAL61931908). The semi-rigid case with handle and shoulder strap CQ 20B-CAS (Algam EKO code GAL61931907) is also available for convenient transport.
