Qu-7 takes the ever-popular Qu-32 form factor and adds Allen & Heath’s powerful XCVI processing, new FX engines and Everything I/O connectivity. There’s also a larger capacitive touchscreen, channel strip displays, customisable layers and extra SoftKeys.

Both the Qu-7 and Qu-7D are 32 input channel, 96kHz digital audio mixers, combining high performance audio processing and professional features with ease of use and hands-on control.

The Qu-7 and Qu-7D are multi-purpose mixers suitable for live music/band use, AV and install, studio and broadcast. Workflow and UI have been designed to make operation easy for inexperienced users or volunteers, provide familiarity to those transitioning from analogue mixing and give quick access to more advanced features for the experienced engineer.
