Allen & Heath SQ-Rack
15-01-25
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.
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.
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.
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.
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.
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.
