Allen & Heath SQ6+ 48 Channel / 44 Bus / 25 Fader Digital Mixer with RackUltra FX

SQ6+ Overview

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

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

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

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.
