Allen & Heath CQ-18T Description

The Allen & Heath CQ-18T combines professional digital mixing functionality with an intuitive interface designed for musicians, sound engineers, and AV operators. Its 96 kHz FPGA processing engine provides detailed audio control across 16 mono input channels and three stereo input channels. The mixer features eight balanced XLR mic/line inputs, eight XLR/1/4-inch combo inputs, and a dedicated stereo line input. Two XLR main outputs and six balanced TRS auxiliary outputs support main PA systems, stage monitoring, and additional audio routing.

The 7-inch capacitive touchscreen provides direct access to channel processing, effects, routing, and system settings. Quick Channels offer application-specific processing with simplified controls, while Complete Channels provide access to detailed equalization, gating, compression, and other parameters. Gain Assistant automatically sets and monitors microphone preamp levels, while Feedback Assistant identifies and suppresses feedback frequencies. Automatic Mic Mixer functionality dynamically balances microphone levels for clearer speech during conferences, presentations, and other spoken-word applications.

Four onboard effects engines provide reverb, delay, and modulation processing, with FX Assist helping effects respond dynamically to incoming signals. The mixer also includes four DCAs and four mute groups for convenient control of multiple channels. Built-in dual-band Wi-Fi allows wireless operation using the CQ-MixPad app on compatible computers and mobile devices, while CQ4You enables performers to adjust their own monitor mixes. Three customizable Soft Rotaries, three SoftKeys, and a configurable footswitch connection provide additional hands-on control.

Recording and playback capabilities make the CQ-18T a flexible solution for both live performance and audio production. Its 24x22 USB-B interface supports multichannel recording and playback at 48 or 96 kHz, while the SD card slot provides standalone multitrack recording without a computer. USB-A supports stereo recording and playback, and built-in Bluetooth allows convenient stereo audio playback from compatible devices. Weighing just 6.6 lb (3 kg), the compact desktop enclosure is easy to transport and can be installed in a standard 19-inch rack using an optional rackmount kit.
