SQ-Rack
48 Channel / 36 Bus Rackmount Digital Mixer

A New Standard in Compact Digital Mixing

48 channel, 96kHz rackmount digital mixer for live sound, AV and installation.

SQ-Rack is the ultimate tool for audio professionals, delivering Allen & Heath’s renowned 96kHz SQ core in a compact, rack-mountable design. Perfectly crafted to meet the demands of live sound and installation environments, SQ-Rack combines power, flexibility, and intuitive control in one versatile solution.

Core. Connectivity. Control.

SQ-Rack packs SQ’s 96kHz XCVI core into a shallow 4U rack-mount form factor with built-in I/O, powerful SLink connectivity, option cards, and multichannel USB. Enjoy hands-on controls and customisable screens, along with remote access via SQ apps for ultimate control of your audio.

Core
96kHz XCVI Processing

SQ-Rack is built on Allen & Heath’s renowned 96kHz XCVI FPGA engine, delivering exceptional high-resolution audio quality, ultra-low latency of <0.7ms and variable bit depths for optimised dynamic range. XCVI allows SQ to handle 48 input channels at 96kHz, with massive mix headroom thanks to a 96bit accumulator, and the sheer power to embed our acclaimed DEEP plugins into all 48 input channels and all mixes.

Connectivity
Comprehensive I/O Expansion

SQ-Rack features 16 high-quality onboard mic preamps and 3 stereo line inputs, and thanks to the integrated SLink port, adding more inputs and outputs is easy. Up to 48 mic inputs can be added via Allen & Heath’s extensive “Everything I/O” range of audio expanders.

You can just slot in one of our 64×64 audio networking cards for seamless integration into Dante and Waves networks, digital FoH/Monitor splits with SQ, Avantis and dLive mixers via SLink, or for MADI connectivity with third-party equipment.

Control
No Faders? No Problem!

Despite SQ-Rack’s faderless design, there are no compromises when it comes to control.

The SQ-Rack’s faders screen provides instant access to level controls, plus 8 SoftKeys and 4 Soft Rotaries – all assignable with LCD displays – so you get to choose which functions you have at your fingertips.

The SQ MixPad app for Android, iOS, Windows, and macOS provides access to the SQ-Rack’s mixing functions from anywhere in the venue, with an offline mode allowing preparation of scenes or shows away from the venue.

For less technical users, the SQ-Control app provides simplified access in-app in addition to a dedicated screen on the SQ-Rack itself. SQ-Control can be configured by an admin user to deliver just the right amount of control for each application or dry hire, whether that’s single fader control of background music from behind the bar or controlling live stream levels in a House of Worship.

Processing & FX

All the Tools for the Perfect Mix

Processing
All The Power You Need

Every input has HPF, a super-fast gate with sidechain and filter, a musical 4-band parametric equaliser with RTA, and Peak/RMS compressor for control and shaping of levels and transients.

Mixes have both a parametric and 28 band graphic EQ along with compressor as standard, all ready to switch in when required.

Add-Ons
Take Your Mix to the Next Level

With SQ-Rack’s DEEP processing architecture, add studio quality compressor and preamp emulations to your inputs and mixes—no extra setup, zero latency, and all integrated seamlessly into your mixer

FX
World-Class FX

Allen & Heath has a well-earned reputation for crafting FX emulations that rival the very best plug-ins, but with none of the associated hassle. SQ-Rack is armed with 8 stereo FX engines and features the acclaimed RackExtra library of emulations of legendary classic reverbs, gated reverbs, delays, modulators and more. All FX have dedicated stereo returns, so you don’t need to consume input channels.

AMM
Advanced Automatic Mic Mixer

Ideal for conferences and multi-mic environments, the advanced AMM feature offers two independent 24-channel mixers or a combined 48-channel setup—enabling clear, consistent sound in complex, multi-speaker settings with zero added latency.
Crafted for Live Sound and Installation Environments

Whether you’re equipping a venue, a touring band taking it to the next level, or building a professional in-ear monitoring system, the SQ-Rack is built for any challenge. From installations in bars to cruise ships, or integration with larger systems to bands on the move and IEM/pro touring, SQ-Rack is the ultimate solution to provide crystal clear sound, every time.

Installation
Stand-Alone or Integrated

From intimate bars to cruise ships and large venues, SQ-Rack excels in fixed installations or as part of bigger systems. With its compact design and powerful capabilities, it’s the natural fit for premium sound.

Live Sound
Ready for the Road

Touring bands and engineers can take their sound to the next level with SQ-Rack. Mix front-of-house (FOH) and monitors with ease, all while enjoying portability and reliability in every gig.

Monitor World
The Ultimate IEM Mixer

With 12 stereo mixes, ultra-low latency under 0.7ms, and powerful parametric and graphic EQs on every mix, SQ-Rack is the perfect centrepiece for in-ear monitoring setups. Its shallow 4U size fits easily into IEM racks, making it ideal for touring.

Built for the rigours of the road, SQ-Rack lets you take control of your monitor mixes for a consistent sound at every show without relying on house equipment. Need more output options? Add a DX012 output expander for even greater connectivity. Digital split to FOH? Slot in one of our audio networking cards.

USB
Flexible Multitrack Recording

Capture every performance effortlessly. With the integrated SQ-Drive, recording multitrack or stereo mixes to a USB device storage is a seamless, hassle-free experience—no need for additional software or external devices.

SQ-Rack also features a 32×32 96kHz USB interface that is ASIO and Core Audio compliant, ensuring smooth compatibility with your preferred DAW, perfect for virtual soundchecks, playback, and multitrack recording needs.

Built to Last. Engineered to Adapt.
Designed for the Pro

With its robust all-metal chassis, SQ-Rack offers exceptional strength and rigidity. Its innovative mechanical design allows for front or rear mounting in multiple configurations—including flush, recessed, or freestanding—for flexibility and convenience.

ME Personal Mixing System
Give Artists Control

SQ-Rack is fully compatible with the ME Personal Mixing System, allowing performers to take control of their own monitor mixes. Any number of ME-1 and ME-500 personal mixers can be daisy-chained from the mixer’s SLink port, or from a connected remote expander.
