Qu-SB 32×32 USB Audio Interface

The Qu-SB is an ultra-compact, 18in / 14out digital mixer which frees you to mix from anywhere in the venue and provides a smart, portable solution for performing bands and artists.

It's designed to integrate 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.

Record without a Computer
Qu has an 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.

Automatic Mic Mixer
AMM is vital in applications such as conferences, meetings and panel discussions where a number of microphones are open at the same time.

Reducing background noise and minimising the risk of feedback, the Automatic Microphone Mixer 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.

Everything I/O
The Qu-SB is a self-contained mixer, so if you’ve already got the analog cables, you’re good to go.

But if you’re thinking of trading in the multicore for a Cat5 digital snake, the built-in dSNAKE™ port has you future-proofed, allowing connection to a remote AB168, AR2412 or AR84 Stagebox from our Everything I/O range of remote expanders (sold separately).

Record. Stream. Mix.
Qu’s built-in interface streams 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 tunnelled over the USB and network connections, this can be mapped to the faders of your favourite DAW using the A&H MIDI Control app which provides easy setup and emulation of HUI or Mackie Control protocols on Mac OS X and Windows systems.

Want to livestream? Easy. Just send a stereo mix over USB and your streaming software will do the rest.

Processing & FX
Qu’s dynamics and FX algorithms are derived from those used in Allen & Heath's pro touring series.

It 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, so you’re not tying up your mono and stereo input channels, and each Stereo FX Return has a dedicated 4 band PEQ.
