General precautions
••••
To prevent damage to the controls and cosmetics, avoid placing heavy objects on the
control surface, obstructing movement of the motorised faders, scratching the surface or
touch screen with sharp objects, or rough handling and vibration.
••••
Protect the equipment from damage through liquid or dust contamination. Avoid dust or
small objects getting into the fader slots. Cover the mixer when it is not being used for a
long period.
••••
Computer and touch screen technology can be affected by extreme cold. If the
equipment has been stored in sub-zero temperatures allow time for it to reach normal
operating temperature before use at the venue. Recommended operating temperature
for Qu is 5 to 35 degrees Celsius.
••••
Avoid using the equipment in extreme heat and direct sunlight. Make sure the mixer
ventilation slots are not obstructed and that there is adequate air movement around the
equipment.
••••
Transport the Qu using a touring grade, purpose designed flightcase with adequate
foam lining and internal support for protection.
••••
Clean the control surface with a soft brush and dry lint-free cloth. Do not use chemicals,
abrasives or solvents.
••••
It is recommended that servicing is carried out only by an authorised Allen & Heath
agent. Contact details for your local distributor can be found on the Allen & Heath
website. Allen & Heath do not accept liability for damage caused by maintenance, repair
or modification by unauthorised personnel.

Qu-Pac is the mix engine of the Qu-32 in a compact rack mountable format. It has the same local
connections as the Qu-16 and can be expanded to use the additional Qu-32 channels and outputs
by adding dSNAKE AudioRacks. It does not have faders and is intended for iPad wireless control.
However, all channels and functions can also be controlled directly from the front panel using its
touch screen.

Scene, Library and Show memories - All Qu mixer memories are compatible. Files created on
one model can be transferred via USB key and loaded on the other. The extra features of the
bigger models will be ignored when their file is loaded on a Qu-16. The extra features of the bigger
models will be reset to factory default when a Qu-16 file is loaded.
Note - To be compatible, ensure all your Qu mixers are loaded with the same version of firmware
later. Check the Allen & Heath web site for the latest firmware available.
USB Audio - A USB hard drive formatted on one model can be used on the other. Stereo and
multitrack Qu-Drive recordings are compatible. USB B audio streaming is compatible, but note that
the Qu-16 is 24out/22in, the Qu-24 is 32out/30in, and the Qu-32 and Qu-Pac are 32out/32in.
Firmware - Different firmware is needed for each model. Choose either the Qu-16, Qu-24, Qu-32
or Qu-Pac file when downloading firmware from the Allen & Heath web site. The firmware version
number will be the same for each update that is made available. The procedure for updating
firmware is the same for all models.
Qu-Pad and Qu-You apps - These iOS apps are compatible with all Qu mixers. They identify the
model and load the appropriate controls when you log in.
Note - Make sure the app version and mixer firmware versions are compatible.

Group, Mix, Matrix outputs
level outputs for the mono and stereo mixes, for example to
feed monitor amplifiers, external processing devices, delay
fill speaker systems and recording devices. These use low
impedance, high quality differential driver circuits for
connection to +4 or 0dBu equipment. Maximum output is
+22dBu.
Professional equipment provides ‘balanced’ connections for
maximum interference rejection over long cable runs. If you
are connecting to ‘unbalanced’ equipment then make sure
the XLR pin 3 (signal cold) is linked to pin 1 (signal ground).
Main LR output
the main Left and Right stereo mix. These typically plug into
the FOH speaker processor, amplifier or powered speakers.

4.4 Powering up the mixer
The Qu mixer has an internal universal voltage power supply
unit. This means you can use your mixer in most parts of the
world without the need to modify the unit as long the local
mains supply is within the range:
Mains Voltage = 100 to 240 V.AC
Mains Frequency = 47 to 63Hz
Important - Before starting, read the Safety Instructions
Sheet packed with the mixer. These can also be
downloaded from the Allen & Heath website.
Also read the safety notes printed on the rear of the mixer.
AC MAINS IN
mixer to the local mains supply. Plug in a mains lead with
moulded plug suitable for your territory. A suitable mains
lead is shipped with the mixer.
Note – Do not replace the mains plug or modify the lead in
any way. For your own safety and that of the operator and
performers do not remove or defeat the ground connection.
A cable clamp is provided. You can slot the cable into this
or lock it in place. To lock the cable use a star head Torx
T20 screwdriver to refit the clamp around the cable.
Fuse
– Mains input fuse to protect the mixer circuits in the
unlikely event of a failure or excessive power surge. If you
need to replace the fuse always use one of the same type
and rating as printed on the rear panel. If the replacement
fuse blows then refer to your authorised Allen & Heath
service agent for advice.

The Qu mixer provides local sockets on its rear panel for all audio inputs and outputs. It can also work
with remote audio by connecting over a single cable ‘digital snake’ to an Allen & Heath AudioRack, or to
the Allen & Heath ME Personal Mixing System.
5.1 Connecting to a remote AudioRack
The Qu can connect to an Allen & Heath AudioRack so that the audio can be plugged into a rack on
stage and routed to the mixer over a single Cat5 cable ‘digital snake’ plugged into its dSNAKE port.

channels of audio in both directions together with
remote control of the preamps.
Cat5 cable – Use STP (shielded twisted pair) Cat5e or
higher cables. Those with both foil and braided
screens provide shielding from interference and are
generally more rugged. Stranded core cables are less
prone to damage when kinked or repeatedly coiled.
Remote Inputs - dSNAKE inputs are mapped one-toone to the Qu input channels. They are not patchable.
Note - dSNAKE does not add channels to the mixer.
Choose either Local (rear panel) or dSNK (remote)
input for each channel.
Remote Outputs - Qu outputs can be patched to the
output sockets on the remote racks. These duplicate
the outputs on the Qu rear panel.
