The Allen & Heath Qu-3D is a 32-input, 96kHz digital mixer built for engineers and integrators who need professional full-featured mixing in a space-constrained environment. The compact 8+1 fader desktop form factor makes it well suited to fixed AV installs, broadcast control rooms, conference suites, and studio applications where rack space and surface area are at a premium. Unlike larger-format consoles, the Qu-3D is designed to sit on a desktop at a working angle, putting hands-on control within reach without occupying a full FOH position. The built-in 16x16 48/96kHz Dante port distinguishes the Qu-3D from the standard Qu-3, enabling direct interoperability with Dante-enabled stagebox expanders, amplifiers, processors, and recording systems over standard network infrastructure. The 128x128 SLink port adds further I/O expansion headroom for larger system configurations. Six onboard FX engines, automatic mic mixing for up to 32 channels, Gain Assistant, and Feedback Assistant reduce setup time in fast-turnaround environments. A 7-inch capacitive touchscreen, motorized faders, and six customizable channel strip layers give operators fast access to the full mix without mode-diving. For recording and redundancy, the Qu-3D supports 32x32 multichannel capture via USB-C audio interface and SD card recording up to 32x32 at 48kHz or 16x16 at 96kHz. Remote control through free Windows, macOS, iOS, and Android apps extends flexibility for single-operator or remote-monitoring scenarios. Optional DEEP processing and RackExtra FX add-ons allow the system to grow with project requirements, and 19-inch rack mounting is available via an optional kit.
