Description
The Allen & Heath SQ-6 is a 48-channel digital mixer built on the 96 kHz XCVI engine for ultra-low-latency, high-resolution performance. It features 24+1 motorised faders, a 7″ touchscreen, and an efficient drag-and-drop workflow supported by 16 SoftKeys and 4 Soft Rotaries. The console provides 8 stereo FX engines, full channel processing with EQ and dynamics, and an onboard 32×32 USB interface for multitrack recording, streaming, and virtual soundchecks. SQ-Drive offers direct recording to USB, while Automatic Mic Mixing simplifies multi-mic environments. With SLink expansion, Dante or Waves options, and ME personal mixing support, the SQ-6 delivers a flexible and scalable solution for live, studio, and installation setups.


Pro-Level Audio Engine
Powered by a 96 kHz XCVI FPGA core, the SQ‑6 delivers ultra-low-latency, high-resolution audio for live, studio, and AV applications. DEEP Processing runs premium compressor and preamp models directly on channels without extra latency. Its advanced mix architecture maintains clarity and consistency even in complex productions.


Intuitive Touch Workflow
A responsive 7″ touchscreen pairs with high‑grip illuminated encoders for clear visual feedback and fast hands‑on control. Drag‑and‑drop channel layout and color‑coded strips make organizing mixes straightforward and customizable. Assignable SoftKeys and Soft Rotaries provide instant access to key functions, speeding navigation during demanding performances.


USB Recording & Streaming
The SQ‑6 features a built-in 32×32 USB audio interface for smooth multitrack recording, playback, livestreaming, and virtual soundchecks. SQ‑Drive enables direct USB recording without a laptop or drivers, while MIDI control allows seamless integration with DAWs and remote control apps, supporting hybrid live-and-studio workflows.


FX Engines & Mic Automation
Eight stereo FX engines with RackExtra models deliver studio‑grade reverbs, delays, and modulation with dedicated returns. Integrated Automatic Mic Mixing intelligently manages multiple microphones for conferences, panels, and broadcast environments. SLink expansion adds remote I/O and personal‑monitoring systems for scalable stage and installation setups.
