QU ECOSYSTEM

Qu provides much more than just a mixer. Qu is an entire ecosystem with Remote AudioRacks allowing I/O to be placed where it’s needed, ME Personal Mixers expanding monitor mixes and enabling simple, time-saving local control, Qu Apps for complete remote setup and wireless mixing on stage or anywhere else in the venue, ProFactory Mic presets to speed up preparation time and ensure the best sound, plus USB recording and DAW integration for powerful workflow optimisation from one centrepiece device.

ANALOGIQTM PREAMPS

Qu-24 features twenty-four AnalogiQTM digitally controlled preamps with advanced zero-crossing detection and a padless 1dB-step gain stage, which have been closely allied to the DSP for optimal gain accuracy and audio transparency. The analogue signal is captured by high-class, low latency 24bit analogue to digital converters, and are matched to 24bit digital to analogue converters to deliver the required high quality output. The AnalogiQTM 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 MIXING EXPERIENCE

Having massive processing power and advanced functionality counts for nothing if you can’t access the controls you need in a heartbeat. The 800×480, True Colour Touchscreen and its dedicated rotary encoder form the heart of Qu-24’s interface, providing super-fast access to all settings and parameters. Dedicated keys and screen tabs quickly guide you to meter and RTA views, FX racks, channel processing, USB audio control, scenes, setup menus and much more. Complementing the touchscreen is the SuperStrip – a set of single function physical controls for instant access to gain, HPF, 4 band PEQ, gate, compressor, GEQ and pan. The screen overview also follows the control being turned.

ONE CHANNEL / ONE FADER

Qu-24 has a fader per mono input channel and fewer fader layers for simpler, quicker workflow. Some digital mixers don’t offer a fader per physical input, meaning you have to access an additional fader layer to control these channels. This can be confusing and time consuming. Because every mic input is presented on its own fader for fast, easy control, this makes Qu-24 the perfect mixer for first-time converts from analogue to digital and those not comfortable working with several layers of faders.

TOTAL RECALL

True digital mixing is about being able to save and recall Scenes (snapshots) at the press of a button. Qu can store up to 100 full Scenes for recall and Channels or Mixes can be made Safe from being overwritten. Qu-24 features 25 motorized ALPS faders, 24 allow instant access to all input channels and masters over 2 layers, and a dedicated master fader dynamically follows the Mix selection. A third User-defined Custom layer is available for ad-hoc strip layout, where any combination of Inputs, FX Sends, FX Returns, DCA’s and Mix masters can be assigned.

PROFACTORY MIC PRESETS

Allen & Heath has teamed up with leading microphone manufacturers and top engineers at Audio-Technica, Sennheiser, and Shure to provide EQ Library presets for a large number of popular and industry standard microphones. Presets for vocals, electric guitar, acoustic guitar, drums, brass and woodwind have been painstakingly crafted to offer you the best possible starting point for the source and your microphone of choice. Whether you’re a keen amateur or a seasoned professional, you can get to work quickly and easily, saving valuable time so you can concentrate on EQ’ing the source and room acoustics.

QU-DRIVE

Qu-24 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. On top of this, 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)

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.

MAC OS AND WINDOWS DAW INTEGRATION

Qu-24’s built-in audio interface streams up to 32 selectable tracks to your Mac or PC and returns from the computer can be easily assigned to the Input channels. The interface is class-compliant on Mac OS X making it truly plug ‘n play and will be recognized straight away by any DAW supporting Core Audio, including Logic, Cubase, Reaper, and Pro Tools. An ASIO and WDM compatible driver is available for Windows computers. Standard MIDI control is tunnelled over the USB connection so you can map the faders to the tracks of your favourite DAW. A DAW Control driver is available for easy setup and emulation of HUI or Mackie Control protocols on Mac OS X and Windows* systems.
