48 Channel / 36 Bus / 17 Fader Digital Mixer

Drag-and-Drop Layout
Channels and mixes can be dragged and dropped to any strip, with custom naming and colour coding on the displays, allowing you to build a mixing environment that works for you.
At-a-Glance Metering
Each strip features our patented Chromatic channel metering system, giving you at-a-glance level indication thanks to LEDs with variable brightness and colour.
Intuitive Control
SQ’s dashboard is centred around a high-res 7” touchscreen, framed by an array of high-grip, illuminating encoders to create an intuitive, integrated blend of clear visual feedback and immediate, hands-on control.
Speed Up Your Workflow
All SQ mixers feature SoftKeys which can be assigned to commonly used functions. The SQ-6 and SQ-7 also provide assignable Soft Rotaries for even more custom control.
Processing & FX
All the Tools for the Perfect Mix

Processing
Powerful Processing
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.

FX
World-Class FX
SQ is armed with 8 stereo FX engines and comes complete with the acclaimed RackExtra library, featuring emulations of legendary classic reverbs, gated reverbs, delays, modulators and more.
Every engine has its own dedicated stereo return too, so you don’t need to use up any of your 48 input channels.

Integrated USB Interface
Record. Stream. Mix.
SQ’s built-in 32×32 96kHz audio interface enables easy multitrack recording, backing-track playback, livestreaming and virtual soundcheck.
The interface is class-compliant on Mac OS X making it truly plug ‘n play, with ASIO and WDM compatible drivers available for Windows computers.
You can even map the SQ’s faders, rotaries, channel keys and softkeys to control your favourite DAW using the Allen & Heath MIDI Control app.
Add-Ons
Take Your Mix to the Next Level
Proven on countless world-tours with international artists, DEEP Processing and RackExtra FX from our award-winning dLive digital mixing system is now available within your SQ.

SQ-Drive
Record to USB
The integrated SQ-Drive makes it quick and easy to capture and playback 16 channels (96kHz), 32 channels (48kHz), or a stereo recording of the performance direct to a USB key or drive.
No software setup, no soundcard driver issues and no extra laptop to bring to the performance.

AMM
Automatic Mic Mixer
SQ’s advanced automatic mic mixers (AMM’s) make it a natural choice for mixing conferences, panel talks and TV shows. They’re fully integrated in the mixer too, with no extra latency, so you don’t need to route the audio to an internal DSP rack or an external plugin system.
Two fully independent 24 channel AMM’s can be utilised for two zones or combined into a single 48 channel AMM for larger events.

Built to Last
Designed for the Pro
We know that the live environment can be tough on gear – so for SQ we devised our most punishing regime of testing and retesting yet.
From its 3-tier, all metal chassis to its extruded aluminium light bar, SQ has tremendous strength and rigidity underlying its good looks.
Networking and I/O

All the Ins and Outs
Thanks to its SLink port, SQ can also be expanded up to a total of 48 mic inputs via the Everything I/O family of rack and stage box expanders making it a flexible, mix ‘n’ match solution for owners of other Allen & Heath digital systems.
