48-channel 96 kHz digital mixer with 24 Mic/Line inputs, 12 stereo Mix buses, 8 RackExtra FX engines and 4 RackUltra FX engines.
Allen & Heath SQ6+ is a professional SQ+ series digital mixer designed for live sound, AV, recording and installation applications. It combines the 96 kHz XCVI processing core, high-resolution audio and ultra-low signal latency with extensive hands-on control, DEEP Processing and the latest-generation RackUltra FX processing.
Compared with the compact SQ5+, SQ6+ provides a larger control surface and more local I/O, with 25 motorised faders, 16 assignable SoftKeys, 4 SoftRotaries, 24 XLR Mic/Line inputs and 14 XLR outputs. This makes SQ6+ particularly well suited to larger and more complex productions where fast access to more channels and functions is essential.
SQ6+ provides 48 input channels, 12 stereo Aux/Group Mix buses + LR and 6 mono/linkable Matrix buses. Every input channel includes HPF, Gate with sidechain and filter, freely assignable Insert, 4-band parametric EQ with RTA and Peak/RMS compressor. Mix channels include parametric EQ, 28-band graphic EQ and compressor as standard.
DEEP Processing allows emulations of classic analogue processors to be embedded directly into channel and Mix strips without adding signal latency, with processing available across all channels simultaneously.
What's New in SQ6+?
SQ6+ retains the core strengths of the SQ platform while the new SQ+ generation introduces several significant upgrades:
- 4 × RackUltra FX engines with dedicated stereo Send/Return channels in addition to the 8 RackExtra FX engines
- 12 FX engines in total - 8 RackExtra FX + 4 RackUltra FX
- New 9" touchscreen with redesigned dark GUI
- New illuminated high-grip encoders for improved hands-on control and visual feedback
- Drag-and-drop channel and Mix assignment
- Enhanced channel naming and colour coding on the displays
- Enhanced Chromatic Channel Metering with level indication down to -72 dB
- 6 mono/linkable Matrix buses
- 128×128 Intelligent SLink connectivity for the Everything I/O ecosystem
- Support for the latest generation of DEEP Processing add-ons
- 2 × 24-channel AMMs, combinable as a single 48-channel Automatic Mic Mixer
- New SQ+ MixPad and SQ+4You remote-control apps
One of the most significant additions to the SQ+ generation is RackUltra FX. SQ6+ features 4 RackUltra FX engines with dedicated stereo Send/Return channels alongside the 8 RackExtra FX engines. Originally developed for Allen & Heath's flagship dLive system, RackUltra FX provides premium reverbs, vocal tuning and pitch processing, distortion, saturation and more. The RackUltra engines can also run RackExtra FX, providing flexible configuration across all 12 FX engines.
Control
SQ6+ features a 9" touchscreen with a redesigned dark GUI, 25 motorised 100 mm faders, 6 Channel Strip layers, 16 assignable SoftKeys and 4 assignable SoftRotaries.
Channels and mixes can be freely arranged across the control surface using drag-and-drop, with custom naming and colour coding available on the displays. SoftKeys and SoftRotaries provide direct access to frequently used functions and parameters, allowing the surface to be tailored to different workflows.
Chromatic Channel Metering provides clear at-a-glance level indication down to -72 dB using LEDs with variable brightness and colour.
Recording and Playback
The integrated 32×32 USB-B audio interface operates at both 96 kHz and 48 kHz and supports multitrack recording, backing-track playback, livestreaming and Virtual Soundcheck.
Using the Allen & Heath MIDI Control app, faders, rotaries, channel keys and SoftKeys can also be mapped to control your preferred DAW.
SQ-Drive enables direct recording and playback without a computer:
- 16 channels at 96 kHz
- 32 channels at 48 kHz
- Stereo recording and playback
Audio can be recorded directly to and played back from a USB drive.
Connectivity and Expansion
SQ6+ provides 24 XLR Mic/Line inputs, 14 XLR outputs, 3 stereo Line inputs, an XLR Talkback input, 2 TRS outputs and a stereo headphone output locally.
The 128×128 Intelligent SLink port provides direct access to the Allen & Heath Everything I/O ecosystem, including remote stage boxes, I/O expanders and other Allen & Heath consoles.
A dedicated I/O expansion slot supports optional SLink, Dante, Waves and MADI cards, allowing SQ6+ to integrate into complex FOH/monitor splits, broadcast systems and networked audio environments.
For conferences, panel discussions and broadcast applications, SQ6+ includes 2 independent 24-channel Automatic Mic Mixers (AMM). They can operate independently for 2 separate zones or be combined into a single 48-channel AMM.
The free SQ+ MixPad app provides remote control from Windows, macOS, iOS and Android devices. SQ+4You allows up to 8 performers to control their own monitor mixes directly from iOS or Android devices.
