Capture Every Detail
Qu has been designed from the ground up to deliver professional sound quality, from input to output.
Qu-SB features sixteen AnalogiQ digitally controlled preamps with advanced zero-crossing detection and a padless 1dB-step gain stage.
The AnalogiQ preamp design has been refined to offer superb transparency, minimal distortion and an ultra-low noise floor, with a warm, musical sound that is missing from some digital consoles.
The analogue signal is captured by high-class, low latency 24bit analogue to digital converters, which are matched to 24bit digital to analogue converters to deliver the required high quality output.
World Class Processing & FX
Qu’s RackFX dynamics and FX algorithms are derived from those used in our pro touring series.
Some of the world’s most respected audio engineers have chosen to use RackFX on tour in preference to top-end plug-ins and external FX units.
Qu 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.
USB Interface
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 alternative sources 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, with drivers available for Windows systems. It is recognized immediately by any DAW supporting ASIO or Core Audio, including Logic, Cubase, Reaper, and Pro Tools.
Standard MIDI control is tunnelled over the USB and network connections and 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? Simply send a stereo mix over USB and your streaming software will handle the rest.
Qu-Drive
Record without a computer
Qu has an integrated multitrack USB recorder, providing 18 channels of 48kHz, 24bit recording and playback directly to and from your USB key or hard drive.
Capturing multitrack recordings of your shows has never been easier. 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.
In addition, Qu-Drive 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.
AMM
Automatic Mic Mixer
AMM is vital in applications such as conferences, meetings and panel discussions where multiple microphones are open at the same time.
By reducing background noise and minimising the risk of feedback, the Automatic Microphone Mixer helps engineers manage the levels of multiple mic inputs, ensuring that each speaker is heard clearly.
The D-Classic dynamic gain sharing algorithm is inspired by industry standard automixers. Up to 16 microphone sources can be mixed simultaneously, with each channel featuring a priority setting that determines its weight in the total system gain.
The Strong, Silent Type
Strong
Made from 18-gauge, cold-rolled Zintec steel, Qu’s distinctive frame is designed for strength and rigidity. The chassis has been rigorously tested in the lab and withstands extreme conditions, including heavy physical impact.
Silent
Silence is essential in live and studio environments. Qu’s sleek profile promotes optimal airflow through the mixer, eliminating the need for cooling fans and ensuring silent operation.
Remote Control Apps
Qu-SB integrates seamlessly with the fully featured Qu-Pad iPad app, providing fast and intuitive access to all settings. This includes channel processing, meters and RTA views, FX racks, scene management, USB audio control, setup menus, and more.
