IMPORTANT - Read these instructions before starting:
Safety instructions
Before starting, read the Important Safety Instructions printed on the sheets supplied with the equipment. For your own safety and that of the operator, technical crew and performers, follow all instructions and heed all warnings printed on the sheet and on the equipment panels.
System operating firmware
The function of the Qu mixer is determined by the firmware (operating software) that runs it. Firmware is updated regularly as new features are added and improvements made. The firmware version current when this guide was released is noted in the Contents section.
The latest firmware can be downloaded from the Allen & Heath website, transferred to USB key and then loaded into the Qu mixer using the Firmware Update utility.
Check the Allen & Heath website for the latest version of Qu firmware.
Software licence agreement
By using this Allen & Heath product and the software within it you agree to be bound by the terms of the relevant End User Licence Agreement (EULA), a copy of which can be found on the Allen & Heath website ( www.allen-heath.com/legal ). You agree to be bound by the terms of the EULA by installing, copying, or using the software.
Further information
Please refer to the Allen & Heath website for further information, knowledgebase and technical support. You can join our Allen & Heath Digital Community to share knowledge and information with other Qu users.
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.

Scene, Library and Show memories - Qu-16, Qu-24 and Qu-32 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 24 out / 22 in, the Qu-24 is 32 out / 30 in, and the Qu-32 is 32 out / 32 in.
Firmware - Different firmware is needed for each model. Choose either the Qu-16, Qu-24 or Qu-32 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.

4.1 Local Input Connections
Mono Line Input – Balanced ¼” TRS (Tip, Ring, Sleeve) jack input for plugging in line level signals such as multitrack players and radio mic receivers. To work with unbalanced sources use a mono jack or link ring to sleeve within the TRS stereo jack.
Use DI boxes plugged into the Mic input for high impedance, low level sources such as acoustic instrument pickups.
Microphone Input – Balanced XLR input for plugging
in a low level source such as a microphone or DI box. 48V Pin2 = hot can be switched to the socket for condenser mics and active
DI boxes that require phantom power.
Note - To avoid loud thumps, mute the channel before plugging in cables or equipment while 48V is turned on.
Stereo Line Input – ST1 and ST2 balanced ¼” TRS (Tip, Ring, Sleeve) jack inputs for plugging in line level stereo sources such as CD players. The L input normals (switches) through the R input so that you can work with a mono source by plugging into just the L/M input.
To work with RCA phono connections use jack to RCA converter plugs.
Talkback Input – Dedicated balanced XLR input for plugging in a microphone to route to the mixes for the engineer to talk to the performers on stage. Phantom power can be switched to the socket for condenser microphones.

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 – Standard IEC socket for connecting the 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.
Power ON/OFF switch – Press to switch the mixer on. Press again to switch it off.
Switching the mixer on – Press the ON/OFF switch. The rear panel blue Power indicator lights. The mixer takes just a few seconds to boot up. It restores its previous settings. LR mix is selected and its processing shown on the screen.
Note – To avoid loud thumps, do not switch the mixer on or off while the PA speakers are powered. Always switch the amplifiers on last, and switch them off first.
Switching the mixer off – First select the Home
screen. Touch Shut Down to safely complete processes such as parameter storing and USB data transfer or recording. Once complete, press the ON/OFF switch to turn the mixer off.

5. Connecting dSNAKE Remote Audio
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.
dSNAKE carries:
Up to 38 remote input signals
Up to 16 remote output signals
40 personal mixing sends
Preamp control – Gain, Pad, 48V
The Qu mixer provides a locking Neutrik EtherCon socket to protect the connections and ensure suitability for touring. Use a touring grade cable fitted with locking EtherCon plugs.
Maximum cable length = 120m (396’) depending on cable type. Recommended maximum length = 100m (330’).
The ‘digital snake’ – dSNAKE provides a convenient, single Cat5 cable alternative to the typical heavy analogue copper multicore to connect many inputs and outputs on stage. One cable carries multiple 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-to- one 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.
Connecting Qu to the AudioRack – Plug one end of
your Cat5 ‘digital snake’ into the Qu mixer dSNAKE port. Plug the other end into the dSNAKE port of the AudioRack.
Connecting a second AudioRack – The AR2412 and
AB168 AudioRacks include an EXPANDER port. You can use this to connect to an AR84 or AB168 AudioRack.
Note – The AR2412 AudioRack cannot be used as an expander in a Qu system.
Note – You can connect up to two AudioRacks in a Qu system. This includes the main rack and one expander rack.
Once connected and powered up, the Qu touch screen should display the ‘dS’ icon in its toolbar to show that one or more dSNAKE devices are recognised by the system.
Qu Mixer User Guide |
14 |
AP9372 iss.5 |
Available AudioRacks:
AB168 16 Mic/Line in, 8 Line out - Floor, shelf or rack mount
The AB168 AudioRack can be used as a stage box on the floor or a surface, or mounted in a 19” rack using the optional rack ears.
EXPANDER – To connect to a second AB168 to add more input and output sockets. Also compatible with the Allen & Heath ME personal mixing system.
dSNAKE – To connect to the Qu mixer using a Cat5 digital snake.
AR2412 24 Mic/Line in, 12 Line out - Rack mount
EXPANDER – To connect to an AR84 or AB168 to add more
input and output sockets.
MONITOR – To connect to the Allen & Heath ME personal
mixing system.
dSNAKE – To connect to the Qu mixer using a Cat5 digital snake.
AR84 8 Mic/Line in, 4 Line out - Rack mount
EXPANDER – To connect to the Expander port of the AR2412, or connect directly to the Qu mixer via its dSNAKE port.
Inputs – Use the Preamp screen Fn key Source page to choose either ‘Local’ or ‘dSNK’ (remote) for each channel source. AudioRack Input sockets are not patchable. They are mapped one-to-one to each Qu channel.
Note – Adding an AudioRack does not expand the number of Qu channels available.
Outputs – The Qu mixer outputs will appear simultaneously at its rear panel sockets and also at the sockets on the remote rack. AudioRack output sockets are patchable. Qu outputs can be patched to the rack sockets using the Setup / Output Patch / dSNAKE screen.

5.2 Qu Systems
The Qu mixer has sockets for all its inputs and outputs on its rear panel and can therefore be used without any additional rack. However, if you wish to use a digital snake to connect remote stage audio to the mixer using a single Cat5 cable then there are several rack options available. The following diagrams show suggested combinations:
Qu-16 – All inputs and outputs are available locally. Use on stage or with an analogue snake.
Qu-16
Qu-16+AR84 – 8 remote inputs. Provides 4 outputs, ideal for feeding a stereo PA and two
monitors.
Qu-16
Qu-16+AR2412 – Access all inputs and outputs near the stage. ST1-3 provide stereo mic
inputs.
Qu-16
Qu-16+AB168 – Provides a rugged digital snake and stage box for all 16 mic inputs and up to 8 returns.

5.3 The ME Personal Mixing System
The Allen & Heath ME Personal Mixing System can be used with the Qu mixer. This provides customisable personal monitor control for individual musicians and performers on stage.
ME-1 personal mixer – A compact personal mixer able to work with up to 40 channels. Features built-in headphones and monitor output. Intuitive and easy to operate, its 16 select keys can be configured to provide as much or as little control as the musician needs.
The 40 ME channels are mapped from the Qu input channel direct outputs, FX and mixes to dSNAKE. Qu sends audio and stereo status information. Channels can be chosen and grouped to ME-1 keys using the setup function available on the ME-1 mixer.
Multiple ME-1 mixers can be connected in series (daisy chained) by linking the output of one to the input of the next. Alternatively, they can be connected in parallel and powered over their Cat5 cables using a standard PoE Ethernet switch or the Allen & Heath ME-U hub. The ME connects directly to a dSNAKE compatible port using a Cat5 cable.
Connecting ME to the AR2412 AudioRack - ME-1 mixers, a standard Ethernet switch or the ME-U hub can be plugged into either or both the AR2412 MONITOR and EXPANDER ports.

6.1 Fader Strips
The Qu mixer has a group of fader strips, one per channel. These provide access to the input and master channel levels and processing.
The main channel levels, master levels and all sends to the FX and mixes can be easily viewed and adjusted using the faders. The faders can also be used to adjust the Graphic EQ while in Fader Flip mode.
The faders are motorised and instantly move to show the current settings when the layer or function is changed.
Layers – There are three Layers. These provide access to inputs and masters as identified by the labels alongside the layer select keys. Indicators next to the keys show which layer is active.
Press the lower key to access the mono channels.
Press the upper key to access the 3 stereo channels, FX returns, FX sends and Mix masters. Press both keys together to access the user assignable Custom layer.
Note – There is an option in the Setup / Control / Custom Layer screen to enable ‘Custom Layer only’. This lets you choose which channels the user should have access to.

Mute key – Press to turn off the channel audio signal. This affects the send to all mixes including LR, groups, effects and stage monitors. The key lights red when muted. It flashes when muted by a Mute or DCA Group master.
Sel key (select) – Press to access the Channel Processing. Parameters can be adjusted using the SuperStrip controls. The touch screen will display the settings and provide additional controls if either the Processing or Routing screen is active. The Sel key is also used for:
Assign mix routing – Hold down the ‘Assign’ key and press Sel keys to assign channels to the mix currently selected in the Master Strip. The Sel keys light green to show channels assigned to the selected mix.
Assign Pre/Post fade sends – Hold down the ‘Pre Fade’ key and press Sel keys to toggle channel sends pre or post fader for the mix currently selected in the Master Strip. The Sel keys light green to show channels set pre-fade.
Copy channel processing – Hold down the Copy key and press a channel Sel key to copy its processing settings. Then hold down the Paste key and press one or more Sel keys to instantly paste those settings to other channels.
Reset channel processing – Hold down the Reset key and press a channel Sel key to instantly reset all its processing to factory default.
Reset Graphic EQ band – Press Sel to reset the associated GEQ frequency band to 0dB while in GEQ Flip mode.
PAFL key – Press to listen to a channel using headphones and check its level on the main meters. The meter PAFL indicator lights. Press PAFL again to turn it off. A SoftKey can be assigned to clear all active PAFL selections. Options are available in the Setup / Audio / PAFL screen to choose how you want PAFL to work:
Additive mode – Pressing a PAFL key automatically cancels any previous selection. Turn Additive on to PAFL more than one channel at a time.
Sel follow PAFL – Link the Sel switch so that pressing PAFL automatically selects the processing for that channel.
LR to PAFL – Routes the main LR mix to the monitor when there is no PAFL selected.
Output AFL – This option sets the mix strip PAFL keys to monitor AFL (afterfade listen). With this option turned off these keys monitor PFL (pre-fade listen). The default is AFL so that you can check mixes after the master fader.
Input AFL – This option sets the input strip PAFL keys to monitor AFL (afterfade listen). With this option turned off these keys monitor PFL (pre-fade listen). PFL is the usual setting for inputs so that you can check and set their gain before you bring up the faders.
Channel meter – The strip meters let you keep an eye on signal levels while you are mixing. These display channel level before the fader and mute control:
Pk – Lights red to warn that the signal is too hot and gain or trim should be reduced. It turns on 3dB before clipping to warn you before audible distortion. Pk senses the signal at several points within the channel.
0 – Lights when the signal reaches nominal 0dBu allowing a healthy 18dB headroom. This is the normal level for mixing.
Sig – Lights to show signal presence. It turns on at -26dBu.
Fader – Controls the level of the input channel, FX or mix master assigned to it. This can be the main channel fader or a send to an effect or mix depending on which Mix Select key is active in the Master Strip.
The faders can also control the Graphic EQ frequency bands while in GEQ Flip mode. The range of frequencies accessed by the faders is highlighted in the touch screen and labelled at the top of the faders. The centre 0dB flat position is marked on the fader scale.
