Overview:
Experience the power of digital mixing in a compact 4 RU enclosure with the Allen & Heath SQ-Rack, a 48-channel, 36-bus digital mixing console well suited for live sound, corporate A/V, recording studios, and houses of worship. The SQ-Rack features 16 professional-quality microphone preamps, eight stereo FX engines with dedicated return channels, and access to the RackExtra FX library with dozens of emulation of legendary classic reverbs, delays, modulators, and more. The mixer's 12 stereo outputs (configurable as groups or auxes) are well suited for in-ear-monitor setups, while the Auto Mic Mixing function offers quick and easy operation over multiple microphones for conferences, panel talks, and more.
At the heart of the SQ-Rack lies the 96 kHz XCVI Core FPGA engine, which delivers professional, high-resolution audio quality, ultralow latency (less than 0.7 ms), variable bit depth for precision and noise performance, mix coherency down to the sample, and the power to handle high channel / mix counts and ample FX processing. The SQ's DEEP processing architecture allows you to hand-pick boutique compressor and preamp emulations and embed them directly within the mixer's inputs and mix channels, all without adding system latency or setup hassles.

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.
Processing and FX
Every input has HPF, a super-fast gate with sidechain and filter, a musical 4-band parametric equalizer 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.
Great for Live Sound and Installation Environments
Whether you’re equipping a venue, a touring band taking it to the next level, or building a professional in-ear monitoring system, the SQ-Rack is built for any challenge. From installations in bars to cruise ships, or integration with larger systems to bands on the move and IEM/pro touring, SQ-Rack is the ultimate solution to provide crystal-clear sound, every time.
Stand-alone or integrated
- From intimate bars to cruise ships and large venues, SQ-Rack excels in fixed installations or as part of bigger systems. With its compact design and powerful capabilities, it’s the natural fit for premium sound.
Ready for the road
- Touring bands and engineers can take their sound to the next level with SQ-Rack. Mix front-of-house (FoH) and monitors with ease, all while enjoying portability and reliability in every gig.
The ultimate IEM mixer
- With 12 stereo mixes, ultralow latency under 0.7ms, and powerful parametric and graphic EQs on every mix, SQ-Rack is the perfect centerpiece for in-ear monitoring setups. Its shallow 4 RU size fits easily into IEM racks, making it ideal for touring.
- Built for the rigors 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 x 32 96 kHz 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.
