The Allen & Heath Qu-SB is an ultra-compact digital mixer with unrivalled sound quality & world class processing & FX. It’s a smart, portable solution for performing bands and artists which frees you to mix from anywhere in the venue.

There are no faders or touchscreen on the Qu-SB. However, it integrates seamlessly with the fully-featured Qu-Pad iPad app, providing super-fast, easy access to all settings, including channel processing, meters and RTA views, FX racks, scene management, USB audio control, setup menus and much more.

With RackFX dynamics and FX algorithms derived from their pro touring series, the Qu-SB boasts 4 stereo RackFX engines, featuring lovingly crafted emulations of legendary classic reverbs, gated reverbs, delays, modulators, flangers and more. FX are returned to the mix on dedicated return channels, and each Stereo FX Return has a dedicated 4 band PEQ.

A built-in audio interface enables Qu-SB to stream multitrack audio to your Mac or PC via a flexible patching system: all Input channels and the Main LR can be recorded at the same time, or you may choose to record something different such as FX returns or a pair of mixes.

The returns from the computer can be assigned to the Input channels. The interface is class-compliant on Mac OS X – and drivers are available for Windows systems. Either way, it will be recognized straightaway by any DAW supporting ASIOTM or Core Audio, including Logic, Cubase, Reaper, and Pro Tools.

Standard MIDI control is sent over the USB and network connections.

Livestreaming is easy - just send a stereo mix over USB and your streaming software will do the rest.

Record without a computer using Qu-Drive, the integrated multitrack USB recorder providing 18 channels of 48kHz, 24bit recording and playback straight to / from your USB key or hard drive.

Capturing multitrack recordings of your shows has never been so easy. A selectable stereo pair can be recorded alongside the 16 Mono channels, and multitrack audio can be played back to the 16 Mono inputs plus ST1.

Qu-Drive also provides stereo recording patchable from any pair of Mix outputs, the Main LR (pre, post, or summed to mono) or even the PAFL bus, with 2- track stereo playback to ST3.

In applications such as conferences, meetings and panel discussions where several microphones are open at the same time, the Automatic Microphone Mixer reduces background noise and minimises the risk of feedback. This helps the engineer to manage the levels of multiple mic inputs, ensuring that each speaker’s contribution is heard clearly.

The D-Classic dynamic gain sharing algorithm is inspired by industry standard automixers. Up to 16 microphone sources can be mixed at once, with each channel having a priority setting which determines its ‘weight’ in the total system gain.

For future upgrades from multicore to a Cat5 digital snake, Qu-32 benefits from a built-in dSNAKE™ port, allowing connection to a remote AB168, AR2412 or AR84 Stagebox from the Everything I/O range of remote expanders.

Made from 18 gauge, cold-rolled Zintec steel, Qu’s distinctive frame is designed for strength and rigidity. Its sleek profile allows optimal airflow through the mixer, eliminating the need for any fans for silent operation.
