Allen & Heath SQ6+ Digital Mixer 48-Channel Live Sound Console with FX
SQ6+
48 Channel / 44 Bus / 25 Fader Digital Mixer with RackUltra FX
The SQ6+ expands the range with 25 motorised faders, 16 assignable SoftKeys and 4 SoftRotaries giving you more physical control when working with larger, more complex shows. Add 4 built-in RackUltra FX engines and you have a mixer that strikes the perfect balance between hands-on control and portability.
Mixing Has Never Been Easier
A Bigger, Bolder Interface
- SQ+ is centred around a responsive 9” touchscreen with an all-new dark GUI that is fast to navigate and easy to read in any mixing environment. Framed by high-grip illuminated encoders, it delivers an intuitive blend of visual feedback and hands-on control.
Drag-and-Drop Layout
- Channels and mixes can be dragged and dropped to any strip, with custom naming and colour coding on the displays, letting you 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 down to -72dB thanks to LEDs with variable brightness and colour.
Accelerate Your Workflow
- All SQ+ mixers feature assignable SoftKeys for quick access to the functions you use the most. The SQ6+ and SQ7+ also include assignable SoftRotaries for even more custom control.
World Class Processing & FX
Processing
All the Tools for the Perfect Mix
- Every input channel comes equipped with HPF, a super-fast gate with sidechain and filter, a freely assignable insert point, a musical 4-band parametric equaliser with RTA, and Peak/RMS compressor for control and shaping of levels and transients. Mixes include both a parametric and 28 band graphic EQ along with compressor as standard, all ready to switch in when required.
DEEP Processing
Latency Free Emulations
- SQ+ supports the latest generation of DEEP processing add-ons – models of classic analogue hardware embedded directly into your channel and mix strips, adding no latency, and available on every channel simultaneously.
Effects
Two FX Suites. Twelve FX Engines
- SQ+ is equipped with 8 RackExtra FX engines, each with its own dedicated stereo return, giving you access to the acclaimed RackExtra FX suite, featuring emulations of legendary reverbs, gated reverbs, delays, modulators and more.
- Four built-in RackUltra FX engines take SQ+ further, each with dedicated stereo sends and returns. First developed for the flagship dLive system, and proven on international tours, the RackUltra FX suite of add-ons brings premium reverbs, vocal tuning and pitch processors, distortion, saturation, and more to SQ+. The 4 engines can also run RackExtra FX for maximum flexibility.
Recording & Playback
Interface
Record. Stream. Mix
- SQ+’s built-in USB audio interface enables easy multitrack recording, backing-track playback, livestreaming, and virtual soundcheck at up to 32×32 channels at both 96kHz and 48kHz. Class compliant and compatible with Mac and Windows with ASIO and WDM drivers available. You can also map faders, rotaries, channel keys and SoftKeys to control your favourite DAW using the Allen & Heath MIDI Control app.
SQ-Drive
Capture. Playback. Virtual Soundcheck
- The integrated SQ-Drive makes it quick and easy to capture or playback 16 channels (96kHz), 32 channels (48kHz), or a simple stereo mix, direct to a USB drive. No need for a laptop or DAW – just press record.
Connectivity & Expansion
- SQ+ is designed to sit at the centre of whatever system you’re building, and to grow with it.
Everything I/O
- The 128×128 Intelligent SLink port opens up the entire Allen & Heath Everything I/O ecosystem, connecting seamlessly to a wide range of remote stage boxes, expanders, and other Allen & Heath consoles.
Audio Networking
- A dedicated I/O expansion slot supports optional cards for Dante, MADI, Waves and additional SLink connections, making SQ+ a natural fit for complex multi-format installs, FOH/monitor splits and broadcast setups.
Apps
SQ+ MixPad
- SQ+ MixPad gives you the freedom to mix from anywhere in the venue, even if that’s not physically close to the mixer’s location. The app is available for free on iOS, Android, Windows and macOS platforms.
AMM
Automatic Mic Mixing
- SQ+’s advanced Automatic Mic Mixers make it a natural choice for mixing conferences, panel discussions, and broadcast applications. Two independent 24 channel AMM’s can run simultaneously for two separate zones or combine into a single 48 channel AMM for larger events.
Built for the Real World
- The live environment is unforgiving, so SQ+ is built to take it.
- A robust all-metal chassis provides the strength and rigidity to handle the rigours of touring and installation alike, while the new carbon-on-graphite finish with black and white knobs and fader caps gives it a sharp, contemporary look that holds up under real-world use.
