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.

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.
