  • SQ-7 is the 33-fader flagship console in the SQ series, powered by Allen & Heath’s revolutionary 96kHz XCVI FPGA engine. Created to excel in demanding scenarios such as AV, corporate events, live productions and houses of worship, SQ-7 offers pristine high-resolution audio quality and an ultra-low latency of <0.7ms. The console features 32 exceptional onboard mic preamps, plus 8 stereo FX engines with dedicated stereo 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.

    96kHz XCVI Core
    SQ is driven by Allen & Heath’s 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 is the next-generation foundation that allows SQ to handle high channel counts 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.

    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 and super-low latency, and both parametric and graphic EQ on every mix, SQ-7 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.

    Packed with I/O
    As the largest model in the SQ series, SQ-7 also packs the highest number of onboard preamps and built-in output sockets, and being SQ, everything is freely and individually patchable. There are 32 pristine XLR mic or line inputs, along with a talkback input that can serve as an extra input when needed. There are also 3 stereo line inputs that can be used as mono inputs, two using ¼” TRS jacks, and one on a 3.5mm mini jack for convenience. Any combination of direct outs, FX or Mix outputs can then be routed at will to the SQ-7’s 16 XLR, 2 TRS jack and stereo AES digital outputs.

    Expandable up to 48 mics
    Thanks to its SLink intelligent port, SQ-7 can 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 solution for owners of other Allen & Heath digital systems. You can even connect to another SQ, Qu or dLive system for two way audio patching.

    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-7’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 separate zones or combined into a single 48 channel AMM for larger events.

    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
    We think that you should decide how the mixer operates, not the other way around. That’s why we’ve packed SQ with options that let you design your own workflows. Channels and mixes can be individually dragged and dropped to any strip, with custom naming and colour coding on the displays, so you’re in full control of the layout. SQ-7 features assignable 16 SoftKeys and 8 Soft Rotaries with LCD displays, so you get to choose which functions you always want at your fingertips. Each strip features our patented Chromatic Channel Metering system, giving at-a-glance level indication using variable brightness and colour. A ‘channel to all’ mix button instantly accesses all send levels and assignments for the selected channel.

    SQ Apps
    There are two essential apps for SQ – SQ MixPad for engineers and SQ4You for performers.

    SQ MixPad app is available 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.

    SQ4You is a personal mixing app to accompany SQ series mixers, allowing up to 8 performers to control their own monitor mixes from their Android or iOS devices and freeing the audio engineer to focus on the front-of-house sound.

    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.
