Allen & Heath SQ-RACK

Allen & Heath SQ-Rack – The power of the SQ series in a compact rackmount format

The Allen & Heath SQ-Rack packs all the technology and flexibility of the SQ series consoles into a 4U rack unit ready for live sound, broadcast, or fixed installations. Powered by Allen & Heath’s XCVI 96 kHz FPGA core, it delivers high-resolution audio with ultra-low latency under 0.7 ms, and provides up to 48 input channels and 36 mix buses in a compact, rugged chassis.

Designed for sound engineers, integrators, and rental companies, the SQ-Rack combines powerful processing, extensive connectivity, and flexible control. With its 7” capacitive touchscreen, 8 assignable SoftKeys, and 4 programmable Soft Rotaries, it offers an intuitive and efficient workflow for all professional applications.

Built on the same digital core as the SQ-5, SQ-6 and SQ-7 consoles, the SQ-Rack provides a complete mixing environment with RackExtra FX, DEEP processing, Automatic Mic Mixing (AMM), and full compatibility with SQ-MixPad, SQ-Control and SQ4You remote control apps.

Its advanced connectivity includes a SLink port for connecting Everything I/O expanders (DX168, AR2412, AB168, etc.), a 64x64 I/O port compatible with Dante, Waves or MADI network cards, and a 32x32 USB interface for direct recording or streaming. The SQ-Drive function also allows multitrack recording directly to a USB drive without a computer.

The SQ-Rack is the ultimate solution for anyone seeking the power and precision of the SQ engine in a mobile and modular format. Perfect for touring, fixed installations, conferences, or professional in-ear monitoring systems, it delivers performance, flexibility, and total control.
