The Allen & Heath Qu-Pac is a compact desk or rack mount digital mixing system with iPad control. All the full functions of the mixer can also be accessed from the front panel and touchscreen.

The Qu-Pac system combines the features of the Qu family of mixers in a compact format that enables the engineer to mix from anywhere in a venue with the iPad. The Qu-Pad app connects to the mixer over Wi-Fi and gives instant access to all live mixing parameters and settings.

Qu-Pac features 16 AnaLOGIQ recallable preamps and featuring zero crossing detection and an advanced padless 1dB step gain stage, expandable up to 38 inputs via dSNAKE. The analogue signal is captured by high class, low latency 24bit analogue to digital converters matched to high quality 24bit digital to analogue converters to deliver the required outputs.

Qu mixers can be used with analogue cables or via digital Cat5 digital through the Qu’s dSNAKE port, which provides connection to a combination of AR2412, AR84 or portable AB168 AudioRacks. The dSNAKE networking solution boasts a transport latency of only 105us over cable runs of up to 120m / 390′.

Qu-Pac’s 5-inch, 800 x 480, sixteen million colour Touchscreen and its dedicated data encoder form the heart of the Qu interface, providing super-fast, easy access to all settings. 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.

The Qu-Control key brings up a fully customisable screen providing access to channels and settings tailored to the user and application. Several ‘widgets’ can be assigned to the page, these include channel levels, mutes and assignment on/off switches and are arranged to suit the user requirement.

All Qu models boast 4 stereo iLive FX engines from the pro touring series, featuring emulations of legendary classic reverbs, gated reverbs, delays, modulators, flangers and more.

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 recognised straightaway by any DAW supporting ASIO or Core Audio, including Logic, Cubase, Reaper, and Pro Tools.

Forget soundcard drivers and software setup, Qu has an integrated multitrack USB recorder, providing 18 channels of 48kHz, 24bit recording and playback straight to / from your USB hard drive.

An independent set of controls is provided for quick stereo recording of the main LR or other mix outputs, and a 2-track USB return can be routed to ST3 for playback of stereo WAV files.

An advanced yet easy to use Ducker is available on every channel. It can be inserted on the fly on any number of Inputs and Stereo Groups, providing auto signal attenuation and then gently restoring the level to aid the operator in endless applications.

Qu mixers are equipped with 5 cores of high efficiency ARM core processing, with dedicated ARM cores running the touchscreen display and surface, USB streaming, Qu-Drive multi-channel USB recording / playback and Ethernet. Between them the ARM cores provide state-of-the-art processing, working in parallel to deliver extensive control, instant-on operation, and lightning-fast response.

The mixer’s DSP farm exploits next generation dual core DSPs. With plenty of DSP power under the hood the channel processing is only using a fraction of capacity, so Qu is future-proofed, with ample room for updates and extra functionality.

The DSP architecture employs varied bit depths, tailored to specific algorithms, with 48 bits on critical EQ functions and a 56 bit accumulator on the mix bus where it really counts, allowing every nuance of the audio to be captured in the final mix.

Qu mixers are fully compatible with the Allen & Heath ME Personal Mixing System. Any number of ME-1 personal mixers can be chained from the dSNAKE port (or from an AR2412 / AB168 AudioRack if you’ve got one connected to the dSNAKE port).
