Allen & Heath SQ6 48 Channel 96kHz Digital Mixer 24 Onboard PreAmps

SQ-6 is a next generation digital mixer, powered by Allen & Heath’s revolutionary XCVI 96kHz FPGA engine. Created to excel in demanding scenarios such as AV, corporate events, live productions and houses of worship, SQ-6 offers class-leading high-resolution audio fidelity and an ultra-low latency of <0.7ms. The console features 24 exceptional onboard mic preamps, plus 8 stereo FX engines with dedicated return channels and access to the renowned RackExtra FX library. SQ is a natural choice for in-ear monitor setups, providing 12 stereo mixes (configurable as groups or auxes), whilst Automatic Mic Mixing* makes it an excellent choice for conferences, panel talks and more.

Product Features

96kHz XCVI Core: SQ is a future-proofed, next-generation console, powered by Allen & Heath’s 96kHz XCVI FPGA engine. XCVI delivers class-leading high resolution audio quality, ultra-low latency of <0.7ms, variable bit depth for ultimate precision and noise performance, mix coherency down to the sample, and the sheer power to handle high channel / mix counts and ample FX / processing.
DEEP processing ready: SQ’s DEEP processing architecture allows owners to hand-pick boutique compressor and preamp emulations to suit their style and needs. DEEP plugins can be embedded directly within the mixer’s inputs and mix channels, all without adding system latency or setup hassles.
The Ultimate IEM Mixer: With no less than 12 stereo mixes, super-low latency, and both parametric and graphic EQ on every mix, SQ is the perfect companion for in-ear monitoring setups. SQ’s airline-friendly compactness and rugged build quality mean there’s no reason to gamble on house monitor consoles again.
Expandable up to 48 mics: SQ-6 has all the onboard I/O you need for standalone operation. Thanks to its SLink intelligent port, SQ can also be expanded up to a total of 48 mic inputs via a family of 96kHz and 48kHz rack and stage box expanders (e.g. AB168, AR2412, AR84 and DX168), making it a flexible, mix ‘n’ match solution for owners of other Allen & Heath digital systems. You can also link your SQ directly to another SQ or even a dLive system.
Dante, Waves and more: SQ is the centrepiece of a growing ecosystem of apps, expanders, audio networking, personal mixers and more, allowing you to connect, adapt and expand to your heart’s content. It’s compatible with leading audio networking standards too – add an audio networking card such as Dante or Waves to SQ’s I/O port and you’re ready to integrate with installed systems, provide a digital FoH / Monitor split and more.
Flexible multitrack recording: The integrated SQ-Drive makes it quick and easy to capture a 96kHz multitrack or stereo recording of the show direct to a USB key or drive. No software setup, no soundcard driver issues and no extra laptop to bring to the performance. SQ-Drive is also a smart way to manage walk-in music. Also provided is a built-in 32×32 96kHz audio interface for multitrack recording, backing tracks or virtual soundcheck applications. The interface is Core Audio and ASIO compliant and comes complete with MIDI and DAW control capabilities.
Advanced AMM*: SQ’s advanced automatic mic mixer (AMM) features make it a natural choice for mixing conferences, panel talks and TV shows. It’s 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.
Designed for the pro: We know that the live environment can be tough on gear – that’s why we devised our most punishing regime of testing and retesting yet for SQ. From its 3-tier, all metal chassis to its extruded aluminium light bar, SQ has tremendous strength and rigidity underlying its good looks.
The Mixing Experience: With each new design, the Allen & Heath team strives to get closer to the ultimate mixing experience. SQ’s dashboard is centred around a high-res 7” capacitive 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. Channels and mixes can be dragged and dropped to any strip, with custom naming and colour coding on the colour strip displays, allowing you to build a mixing environment that mirrors your own workflow. Each strip features our patented Chromatic channel metering system, giving you at-a-glance level indication thanks to LEDs with variable brightness and colour. SQ-6 also offers 16 Softkeys and 4 Soft Rotaries with displays that can be assigned to the functions you want at your fingertips, and a ‘channel to all’ mix button to instantly access all sends from the selected channel.
SQ MixPad App: The SQ MixPad app is available for free on iOS and Android platforms, providing wireless control of the main mixing functions. This enables the engineer to mix from different listening positions, set up monitor mixes from the stage, or just add extra local control. All you need is an iPad or Android device and a wireless router.
RackExtra 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 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 waste input channels.
ME Personal Mixing System: SQ is fully compatible with the ME Personal Mixing System, allowing the 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.
