computer to the USB B port to stream up to 32 channels of audio
in both directions and send MIDI messages.

Download the Allen & Heath Qu Windows ASIO/WDM driver to
stream Audio and MIDI to a PC.
MIDI is transmitted via the USB B port. Set the Qu MIDI channel
number using the Setup / Control / MIDI screen.
Qu-Drive recording direct to USB drive – You can record stereo
or 18-track multitrack direct to a USB storage device plugged into
the front panel Qu-Drive port.
For more information refer to the ‘Understanding Qu-Drive and
USB’ article in the Qu Knowledgebase at www.allen-
heath.com/support.
Use the USB storage device with the Qu mixer only. Do not use
it for other applications.
Format the USB device on the Qu mixer before recording
using the Setup / Utility / Qu-Drive screen. This clears the
drive and sets up the Qu directory structure.
Patch the sources to record using the I/O Patch / USB Audio
screen. Choose channel sources to be from Insert Sends or
Direct Out.
Record Stereo or Multitrack - Use the Home / Qu-Drive
screen. Recording creates WAV files in Qu directories on the
USB device. Stereo recording uses the same source as
multitrack CH17 and 18.
Play back Stereo or Multitrack – Patch USB as the source to
the channels using the Processing screen Preamp source
popup. Select ‘Qu-Drive’ as the Global USB Source.
Using Qu-Drive Strips for transport control – You can use
Qu-Drive transport control strips for stereo or multitrack
recording and playback, for example, to arm, start and stop
recordings while mixing. Use the Setup screen Strips page to
drag and drop strips to the three available custom strips.
7.6 A few more functions
Signal Generator – The Qu mixer has a built-in signal generator.
Pink noise is an excellent source for testing speakers. It generates
equal energy per octave across all frequencies and can be used to
check that all speaker drivers are working and to listen for phasing
and polarity issues.
Channel Ducker – You can insert a ducker into input channels or
groups. This lets you use any signal to automatically duck
(attenuate) other channels when active. For example, to use a
paging mic as a trigger to duck a background music channel when
in use.
