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, combining power, flexibility and intuitive control in one versatile solution.
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 96-bit accumulator, and the sheer power to embed 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. Thanks to the integrated SLink port, up to 48 mic inputs can be added via Allen & Heath's Everything I/O range of audio expanders.
Slot in one of the 64×64 audio networking cards for seamless integration into Dante and Waves networks, digital splits with SQ, Avantis and dLive mixers via SLink, or MADI connectivity with third-party systems.
Control
No Faders? No Problem.
Despite its faderless design, SQ-Rack makes no compromises on control. The faders screen provides instant access to level controls, plus 8 SoftKeys and 4 Soft Rotaries — all assignable with LCD displays.
The SQ MixPad app for Android, iOS, Windows and macOS provides full access to mixing functions from anywhere in the venue, with offline mode for preparing scenes away from the console.
Processing
All The Power You Need
Every input has HPF, a super-fast gate with sidechain and filter, a musical 4-band parametric EQ with RTA, and a Peak/RMS compressor. Mixes have both parametric and 28-band graphic EQ along with compressor as standard — all ready to switch in when required.
Add-Ons
DEEP Processing
With SQ-Rack's DEEP processing architecture, add studio quality compressor and preamp emulations to your inputs and mixes — no extra setup, zero latency, fully integrated into your mixer.
FX
World Class FX
Armed with 8 stereo FX engines and the acclaimed RackExtra library — emulations of legendary reverbs, gated reverbs, delays, modulators and more — all with dedicated stereo returns so no input channels are consumed.
Installation
From intimate bars to cruise ships and large venues, SQ-Rack excels in fixed installations or as part of bigger systems. Compact design, powerful capabilities.
Live Sound
Mix front-of-house and monitors with ease while enjoying portability and reliability in every gig. Touring bands and engineers can take their sound to the next level.
Monitor World
12 stereo mixes, <0.7ms latency, and powerful EQs on every mix make SQ-Rack the perfect centrepiece for IEM setups. Its shallow 4U size fits easily into monitor racks.
USB
Capture Every Performance
With the integrated SQ-Drive, recording multitrack or stereo mixes to USB storage is a seamless, hassle-free experience — no additional software or external devices required.
SQ-Rack also features a 32×32 96kHz USB interface that is ASIO and Core Audio compliant, ensuring smooth DAW compatibility for virtual soundchecks, playback and multitrack recording.
Build Quality
Built to Last. Engineered to Adapt.
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 maximum flexibility.
