Safety instructions

Before starting, read the Important Safety Instructions printed on the sheet 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.

3.2 Qu Chrome Edition

Qu Chrome Edition introduced a fresh new look for the Qu range with high contrast chrome rotary and fader knobs that also improve visibility in dark conditions. Qu Chrome coincided with the release of new firmware V1.8, which introduced several new features and improvements. Qu hardware and memory files remain fully compatible between editions. Existing black knob Qu mixers can be updated to latest firmware and can also be upgraded to Chrome standard by ordering the following kit from Allen & Heath:

4. Connection Overview

The following connections are available on the rear panel of the Qu mixer. The Qu-16 is shown here.

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 can be switched to the socket for condenser mics and active DI boxes that require phantom power.

 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 (ST2 not provided on Qu-SB). 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. The Talkback Input is not provided on Qu-SB.

4.2 Local Output Connections

Group, Mix, Matrix outputs – Balanced XLR line

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 – Balanced XLR line level outputs for

the main Left and Right stereo mix. These typically plug into the FOH speaker processor, amplifier or powered speakers.

AES out – 2-channel digital output using a single XLR

connection and standard mic (2-core screened) audio cable. It follows the AES (Audio Engineering Society) digital audio standard and can connect to any equipment fitted with an AES input socket. The source to this output is patched using the Setup / Output Patch / Surface screen. Applications include the feed to a PA speaker processor, amplifier, stereo broadcast or recording device equipped with AES input.

Alt out – Stereo ‘alternative’ output on balanced TRS

jacks for connection to +4 or 0dBu equipment such as zone feeds, fill speakers, broadcast or local monitor. The source to this output is patched using the Setup / Output Patch /

Surface screen.

2TRK out – Stereo output on balanced TRS jacks for

connection to +4 or 0dBu equipment such as stereo recorders. It follows the post master fader main LR mix.

 The AES out, Alt out and 2TRK out are not provided on

Qu-SB.

4.3 Other Connections

Lamp – Plug in a 4-pin gooseneck lamp to illuminate the

mixer surface. You can use any industry standard 12V, 5W or lower power lamp. We recommend the Allen & Heath LEDLamp with built-in thumbwheel dimmer. The Lamp connector is not provided on Qu-SB.

USB B – Type B USB connection for multi-channel

bi-directional audio streaming between the mixer and a computer. Follows the high speed USB 2.0 standard.

Refer to the Allen & Heath web site for information on Windows® and Apple® Mac drivers available for Qu.

Network – Fast Ethernet (100 Mbit/s) port for Cat5 cable

connection to a computer for MIDI over TCP/IP control of mixer parameters, or to a wireless router (access point) for live mixing control using the Allen & Heath Qu-Pad app running on an iPad, and Qu-You personal monitoring app. The Lnk indicator flashes to indicate network activity.

Qu Mixer Reference Guide 15 AP9372 iss.10

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 and safety notes printed on 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.

 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.

 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.

Qu Mixer Reference Guide 16 AP9372 iss.10

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.

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-toone to the Qu input channels. They are not patchable.

 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.

 The AR2412 AudioRack cannot be used as an expander in a

Qu system.

 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.

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’).

Qu Mixer Reference Guide 17 AP9372 iss.10

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.

AR2412 24 Mic/Line in, 12 Line out - Rack mount

AR84 8 Mic/Line in, 4 Line out - Rack mount

Inputs – Use the Preamp screen Fn key Source page

to choose either the local (rear panel) socket or a remote (dSNAKE) socket for each channel source. Red buttons show local sources selected, yellow buttons show dSNAKE sources.

Any dSNAKE input socket can be patched to any channel using the Setup / I/O Patch / dSNAKE In screen. Sockets can be patched to more than one channel.

The Qu-16, 24, 32 reset default is one-to-one mapping of local sockets to the channels.

The Qu-Pac and Qu-SB reset default is one-to one mapping of local sockets to CH1-16, and dSNAKE 116 sockets to CH17-32.

 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 / I/O Patch / dSNAKE Out screen.

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.

EXPANDER – To connect to the Expander port of the AR2412, or connect directly to the Qu mixer via its dSNAKE port.

Qu Mixer Reference Guide 29 AP9372 iss.10

Preamp

An analogue preamplifier (‘head amp’) matches each connected microphone or line signal to the operating level of the console before it gets converted to digital to be processed and mixed with the other channels.

Source lets you choose one of four sources as the

input to the channel. Press the Fn key to open the

Source screen.

Local = Mic/Line socket on the Qu rear panel.

dSNAKE = Remote preamp from AudioRacks.

Qu-Drv = Playback from USB hard drive.

USB B = Audio streaming from a Mac computer.

Touch the CH buttons to highlight those you wish to change. Select the source from the list.

Input Patching – dSNAKE sockets can be

patched to any channel. A socket can be patched to more than one channel.

Touch the Source page Patch button. This is a shortcut to the I/O Patch / dSNAKE In page. Touch a CH or ST button and turn the screen rotary to select the dSNAKE socket number.

The button code indicates dSNAKE device:

N/C = No AudioRack is connected

Main = First AudioRack

Exp = Second (Expander) AudioRack

The reset default patch is one-to-one mapping of dSNAKE to channel.

 The default patch for Qu-Pac and Qu-SB is

CH1-16 = Local1-16, and CH17-32 = dSNAKE 1-

16.

Input patching can be changed and is stored in Scene memories.

Channel Preamp source

Local (red Gain) – Rear panel Mic/Line sockets

feeding the internal Qu mixer preamps. These are a pad-less design featuring wide gain range.

dSNAKE (yellow Gain) – Remote preamps located in an AudioRack on stage or other remote location and connected to the Qu dSNAKE port via a Cat5 cable. The AudioRack preamps include 20dB Pad switching.

Channel USB source

Qu-Drive source (blue Gain) – Stereo or multitrack

playback from a USB hard drive plugged into the top panel Qu-Drive port. Provides a +/-24dB Trim control.

USB B source (blue Gain) – Multi-channel streaming from a Mac computer via the rear panel USB B port. Provides a +/-24dB Trim control.

Local (red Gain) dSNAKE (yellow Gain)

Qu-Drive (dark blue Gain) USB B (Light blue Gain)

Choose either Qu-Drive or USB. This is a global control that affects all channels.

Qu Mixer Reference Guide 30 AP9372 iss.10

The panel USB Select key in the SuperStrip switches between the current Preamp source (Local or dSNAKE) and the current USB source (Qu-Drive or USB B). This key is not available on Qu-Pac.

Phantom Power

Turn on 48V if the connected device requires phantom power, for example a condenser microphone or active DI box. Touch and hold for 1 second to toggle on or off. This prevents accidental operation.

 To prevent audible thumps make sure the channel

is muted before plugging or unplugging sources while phantom power is on.

Gain

Turn up Gain so that the average loud signal reads into the yellow of the meter. Turn down if any red peak light flashes.

Polarity

Touch Ø to reverse the polarity of the input signal, for example that of the lower mic when working with two microphones on a snare drum.

Delay

Up to 85ms delay can be added to each input channel. In most cases delay is not needed, but can be useful in time aligning sound from the PA to the acoustic sound from an instrument on stage. Allow 1ms per foot distance as a starting point.

Touch and use the rotary to set delay time. Delay can be switched in or out.

Insert

You can choose whether to insert either an FX or a Ducker into the channel signal path. You cannot insert both. Touch to highlight the selection knob and turn the rotary to select FX or Ducker. The inserted device can be switched in or out.

Inserted FX

Go to the FX / Back panel screen to choose and assign one of the 4 internal FX as an Insert into a channel. The FX is inserted after the preamp and before the HPF.

Use the FX / Front panel screen to recall an FX Library and work with the parameters. Touch the D/W control and turn the screen rotary to balance between the ‘Dry’ (direct) and ‘Wet’ (affected) signal.

Inserted Ducker

The Ducker works by automatically reducing (ducking) the level of the channel when a trigger source is detected. For example, an announcement mic could trigger the ducker on a music channel so that the music level is reduced when an announcement is made.

The Ducker is inserted between the HPF and noise Gate.

Ducker

Touch Ducker Setup to open the settings page:

Single – Single channel ducking. The trigger and

settings apply to just this channel.

Gang – Multiple channel ducking. The same trigger and settings apply to all channels set to Gang mode.

 There is only one Gang.

Trigger Input – Touch to highlight and then turn the screen rotary to scroll through the available trigger sources.

Channel trigger sources follow the Global Direct Output setting. This would typically be set to Follow Fader, Follow Mute. The Direct Out source is set in the input channel Routing screen.

Threshold – Sets the level of the trigger source above which the channel will be ducked. The meter shows the trigger level together with threshold pointer and ducking activity (gain reduction).

Depth – Sets how much the channel signal will be ducked. From 0dB (no ducking) to 60dB (full ducking).

Three controls set the speed at which ducking occurs.

Attack – Sets how fast the channel signal is ducked to the level set by the Depth control. Variable 20ms to 600ms.

Hold – Sets how long the channel signal is held at the Depth level after the trigger signal is removed. Variable 40ms to 10s.

Release – Sets how fast the channel signal rises back to its normal level at the end of the Hold period. Variable 250ms to 5s.

 Ducker settings are not part of the channel libraries

or the Copy/Paste/Reset function.

Stereo Linking

Odd/even pairs of mono input channels can be linked for stereo operation.

 Even/odd channel pairs cannot be linked.

The default is all parameters including the preamp, processing and routing linked. Pan becomes a width control when linked. Panning one channel in a linked pair to the left automatically pans the other to the right by the same amount.

Some parameters can be removed from the link using the buttons:

Preamp – Gain/Pad/48V, Polarity Dynamics (Compressor and Gate) - Side Chains Main mix – Fader/Mute, Pan

Touch Apply to accept your changes.

Qu Mixer Reference Guide 32 AP9372 iss.10

Gate

The Noise Gate can be switched in to dynamically turn off the audio when it drops below a certain level. For example, to reduce resonant decay of a kick drum or floor tom, or hiss of a noisy keyboard.

Use the In key or screen button to switch the Gate in or out. This is similar to inserting an outboard rack mounted device into the Insert socket on an analogue console channel.

Set Depth for how much signal reduction you want when the gate closes. 20dB is a typical setting. The GR indicator lights and red screen meter shows the amount of reduction when the gate is closed.

Hold sets how long the gate remains open after dropping below the threshold. Attack sets how fast the gate opens when the signal rises above the threshold. Release sets how fast it closes when dropping below the threshold. Experiment with these controls to achieve smooth operation without a pumping effect.

HPF (high pass filter)

The HPF is used to reduce unwanted low frequency sounds such as vocal popping, wind noise and stage rumble.

Switch the HPF in using the In key or screen button. Use the panel rotary or screen button and rotary to sweep the cut-off frequency until you have reduced the unwanted sound. The filter has an 18dB slope and can be swept from 20Hz to 2kHz. The violet screen curve shows the resulting frequency response.

PEQ (parametric equaliser)

The Parametric Equaliser allows tonal adjustment of the channel sound. It provides independent control of 4 frequency bands, each with three parameters that can be adjusted:

LF (low frequency) LM (low mid frequency) HM (high mid frequency) HF (high frequency)

Gain – Boost or cut frequencies by up to 15dB. Centre 0dB is flat response (no affect).

Frequency – Each band can sweep its centre point frequency across the full range from 20Hz to 20kHz. This means you can overlap bands and have more precise control over problem frequency areas.

Width – Each band has a bell-shaped response. The width of the bell can be varied from a very wide 1.5 octaves affecting many frequencies to a very narrow 1/9th octave affecting a small range of frequencies. Setting LF or HF to widest position using the screen rotary changes its response to shelving.

Experiment with the controls to hear their affect on different sounds. Switch the PEQ in or out using the In key or button to compare the sound. For live mixing it is better to cut rather than boost frequencies where possible.

Note – The lower part of the

Gate meter is a darker green

to show signal ‘noise’ level

below -40dB.

Gate active GR = Gain Reduction

You can turn the PEQ graph fill on or off using the Setup / Control / Preferences screen.

Qu Mixer Reference Guide 33 AP9372 iss.10

Compressor

The Compressor is a powerful tool for controlling the dynamics of the sound, for example to smooth out a bass guitar or to narrow the dynamic range of a vocal to make it more intelligible in a busy mix. At its extreme setting the compressor can be used as a limiter to prevent the signal exceeding a preset maximum level.

A compressor works by dynamically reducing the amount of gain when the signal increases above a certain threshold. This pulls back loud moments. Applying ‘make-up’ gain restores the average volume and also has the effect of bringing up quiet moments. The result is a reduced dynamic range.

While listening to the signal adjust Thres (threshold) to set the point at which compression starts. The GR indicator and red screen meter will start to show that compression is active. Set Ratio for how much compression you want from none (1:1) to full limiting (Inf). A ratio of 3:1 is a good starting point.

Use the In key or screen button to switch the compressor in and out and turn up Gain so that the average volume is similar.

Attack sets how fast the compressor starts to work when the threshold is reached. Release sets how fast it stops compressing when the signal drops below the threshold. For example, adjust these to achieve a

‘punchy’ dynamic sound, or smooth out the response to reduce an audible ‘pumping’ effect.

Two ‘knee’ settings are available. Hard Knee means

that compression is applied at the set ratio as soon as the threshold is reached. Soft Knee means that the compression ratio increases gradually from 1:1 to the set ratio as it approaches the threshold. The curve illustrates this.

4 Compressor types are available using the dropdown menu. Two ‘Manual’ types allow user control of attack and release. Two ‘Auto’ types provide automatic control of the compressor dynamics.

Experiment with the effect of the compressor settings on different sounds. Try to use compression only where it is needed, and avoid compression in stage monitor speakers.

Mix processing

The mix masters provide PEQ, GEQ, Compressor, FX Insert capability and output Delay.

The mixes include Groups, Mono and Stereo Mixes, and Matrix.

To access the Mix processing press the Qu mixer master fader strip green Sel key or Qu-Pac Channel screen select mix button.

Delay up to 170ms can be added to each mix output. This is typically used to time align the PA to the acoustic sound from the instruments on stage, or to align fill loudspeakers to the main PA. Allow 1ms per foot distance as a starting point.

Mix and Matrix

Qu Mixer Reference Guide 34 AP9372 iss.10

Insert switches an internal FX in or out if one has been

patched into the mix. The button is disabled when the insert is not patched. The FX is inserted at the start of the processing before the EQ.

Use the FX / Back panel screen to choose and assign one of the 4 internal FX as an Insert into a mix.

Groups allow FX or Ducker to be inserted. Using the Ducker on a Group provides a quick way to set up multiple channel ducking as well as providing master processing and control for those channels. The ducker works in the same way as that described for input channels above.

GEQ (graphic equaliser)

The Graphic EQ is a popular tool for tuning out resonant frequencies in PA systems, for example when ringing out monitor speakers.

The GEQ allows tonal adjustment of the overall mix sound. It splits the 20Hz to 20kHz audio frequency range into 28 standard 1/3 octave bands from 31.5Hz to 16kHz allowing +/-12dB cut or boost.

Touch the screen In button to switch the GEQ in or out. Touch a slider to highlight it and use the screen rotary to cut or boost its frequency. This affects a small range of frequencies 1/3 octave wide centred on the frequency marked below the slider. The position of the sliders shows the approximate shape of the resulting frequency response curve.

GEQ Fader Flip (Qu-16, 24 and 32)

Press the surface GEQ Fader Flip key to view and adjust the GEQ on the faders while a mono, stereo or the LR mix is selected. The screen highlights the active range of frequencies. Press the switch again to change range or return to normal mix mode.

The faders toggle between the lower and higher ranges of frequencies with a useful overlap. The frequencies are shown on screen and marked on the panel above the faders.

The fader strip Sel key turns on when the slider is at 0dB mid (flat) position while in fader flip mode. Press a Sel key to return a slider to 0dB.

The strip meters display the RTA of the current PAFL signal. The dominant frequency (peak band) lights the red meters. Select the mix PAFL key to view its RTA.

It is better to cut rather than boost frequencies when tuning speakers using the GEQ.

Group (not available on Qu-16)

• Comp

• Channel (Preamp, Gate, PEQ, Comp, Delay)

You can store up to 128 library items including all types.

Press the Fn key on the related Processing screen to open the Library page. The Channel library is available from its Gate, PEQ and Comp screens.

Channel Library – This is available for the mono and stereo input channels

Turn the ‘Recall Preamp’ option on if you want to recall the input preamp settings along with the processing. This includes the settings for all its preamp sources Local, dSNAKE and USB.

Factory Libraries – Built-in libraries are available as examples or to give you a starting point for live mixing. These cannot be deleted or edited.

User Libraries – You can name and save your often used settings for quick recall. User libraries can be overwritten, renamed and deleted using this screen.

Library lists – The left hand list displays related processing block libraries, for example the PEQ. The right hand list displays libraries for complete input Channel processing.

 There is no ‘standard’ setting for instruments in live

mixing as many factors affect the sound, for example the instrument itself, its pickup, the mic used, room acoustics and more. For this reason the Factory libraries simply provide a starting point or examples. You can also save your preferred settings as User libraries.

Channel Libraries are intended to provide a useful starting point for live mixing. Settings are mostly flat with parameters set to typical values for the associated source.

These libraries are available for the mono and stereo input channels. They recall all processing settings including Gate, PEQ and Compressor. Turn the ‘Recall Preamp’ option on if you want to also recall the Preamp settings such as Gain, 48V and Polarity.

Recall these libraries while setting up the mixer before sound check. When sound checking each instrument, start by checking its preamp Gain and then dial in EQ Gain and Gate/Compressor Threshold.

PEQ, GEQ, Gate, Comp Libraries recall just their associated parameters and are intended to provide examples to

demonstrate how the processing can be

used with different instruments and sources.

Libraries starting with ‘ : ‘ can give you a general purpose starting point.

PEQ libraries store and recall both the HPF and PEQ settings.

ProFactory Libraries are PEQ Libraries created by leading microphone manufacturers, and provide starting points for a number of popular, industry standard microphones. These Libraries start with ‘*’

More ProFactory Libraries can be downloaded from the Allen & Heath website.

9.7 Channel Routing

The Touch Screen presents tabs to access a CH or ST channel routing assignments and send levels when its fader strip Sel key is selected and the Touch Screen Routing screen is active. The SuperStrip Pan control provides quick access to the related mix pan setting for the channel. The Fn key is used to access the Mute and DCA Group masters while in any Routing screen.

9.8 Working with the Routing screens

• Press a fader strip Sel key.

• Press the Touch Screen Routing key.

• Touch the tabs at the top of the screen.

• Touch screen buttons and use the rotary.

• Press the Fn key to access the Mute and DCA Groups.

Pan

The rotary Pan control becomes active when an input channel Sel key is active. Its function depends on currently selected Master Strip mix:

LR = Channel main pan FX send = Disabled Group (not Qu-16) = Channel main pan Mono Mix1-4 = Disabled Stereo Mix5-10 = Channel send pan

Pan becomes a Width control when linked for two input channels – Panning one to the left automatically pans the other by the same amount to the right.

Channel Routing screens

Tabs available on the CH and ST routing screens:

Main tab – Global Direct Output settings. These affect all channels.

Mix Sends – Assignments, pre/post, levels and pan to the mono Mixes 1-4 and stereo Mixes 5-6, 7-8, 9-10.

FX Sends – Assignments, pre/post and levels to the FX mixes (Qu-16 has 2, the other models have 4).

Grp Sends – Assignments to the stereo Groups if they are in Group Mode, or assignments, levels and pan if they are in Mix Mode (not on Qu-16).

Mute/DCA Group Assign – Assignments to the Mute and DCA groups.

Channel Direct Output settings

Adjust the channel Direct Output Trim from off to +10dB gain. The default setting is 0dB.

Choose the channel source for the Direct Outputs using the drop-down menu. Choose whether the outputs are affected by the faders and/or mutes. These are global settings affecting all channels.

Qu Direct Outputs can be used for several different applications. Typical settings are shown below:

Single channel FX send – Patch the channel to the input of one of the 4 FX devices, for example to create a delay effect send for a single vocal.

FX = Post Delay, Follow fader On, Follow mute On

Ducker trigger input - Gets its source from the selected trigger channel Direct Output.

Duck = Post Delay, Follow fader On, Follow mute On

Monitor sends - The ME-1 personal monitor mixer gets assigned channel sources from their Direct Outputs.

Monitor = Post PEQ, Follow fader Off, Follow mute On

USB audio sends - These can be sourced from the channel Inserts (default) or from the Direct Outputs.

Live recording = Insert Sends

Qu Direct Output reset default is:

Post Delay, Follow fader On, Follow mute On

Channel Mix Sends screen

Use this screen to work with the sends and assignments from one channel to all the mixes.

Each send can be set Pre or Post fader. It is typical to set monitor sends pre-fade so that the channel fader does not affect the monitor mixes, and to set effects and fill speaker sends post-fade so that their levels do follow the faders.

The channel can be assigned (routed) On or Off to each mix. Touch the Level and Pan buttons and use the screen rotary to adjust their settings.

To work with the sends and assignments from all channels to one mix use the Qu-16, 24, 32 Master Strip

Mix keys and the fader strips, or the Qu-Pac Channel

screen and its Mix Select buttons..

Channel FX Sends screen

Use this screen to work with the sends and assignments from one channel to the FX mixes. These are for Mix>Return effects such as reverb and delay.

The sends can be set Pre or Post fader but it is usual to leave these set post-fade so that the effects follow the channel fader level. Each send can be assigned On or Off. Its Level can be adjusted here.

Qu-16 FX3 and FX4 do not have dedicated sends. However, you can assign any of the Mix1-10 buses to feed these. To do this use the FX / Back panel screen.

Qu Mixer Reference Guide 39 AP9372 iss.10

Channel Grp Sends screen

The Qu-24 includes two stereo Group mixes, and the Qu-32, Qu-SB and Qu-Pac have four. Groups are not available on the Qu-16.

Firmware V1.8 introduced Group Mix Mode. You can choose each Group to be either an audio group or a stereo mix.

Group mode is set for each Group using its master

Routing screen.

The channel Grp Sends screen lets you work with the sends from one channel to all the groups. To work with the sends from all channels to one group, use its Master Strip Mix key and the fader strips.

The Grp Sends screen presents the controls available according to currently selected mode:

Group - Stereo Audio Group with assignments. A Group can be used as a separate output or as a subgroup to LR and the Mixes.

Mix - Stereo Mix with send level, dedicated pan, assignments and pre/post selection. Can be used to expand the number of mixes available, for example to add more monitor sends.

Channel Mute/DCA Group screen

All Qu models provide 4 Mute Groups and 4 DCA groups for mute and level control.

This channel screen lets you assign one channel to any combination of the Mute and DCA groups. To work with the assignments of all channels to one group, press the Fn key to open the Mute/DCA master screens.

The Touch Screen presents tabs to access the Mix master routing assignments and send levels when its fader strip Sel key is selected and the Touch Screen Routing screen is active. The Fn key is used to access the Mute and DCA Group masters while in any Routing screen.

Select a mix master Sel key while the Routing screen is active to:

Adjust the Output Balance between Left and Right sockets of a stereo mix or LR.

Choose the global Channel Source for the selected mix. This is the point in the channel signal path that feeds the mix. This affects all sends to the mix.

• Choose Post-Preamp if you want the sources to

the mix not affected by any channel processing.

• Choose Pre-EQ for a monitor mix if you do not

want the channel EQ to affect the monitor.

• Choose Post-EQ if you want the EQ but not the

compressor to affect the monitor.

• Choose Post-All processing for FX sends.

Mix to Matrix Sends

The Qu-24, Qu-32, Qu-SB and Qu-Pac include two stereo Matrix mixes. These are not available on Qu-16.

The Groups, Mixes and LR can be sent to the Matrix.

The sends to the matrix can be set Pre or Post the send master fader. Each send can be assigned On or Off. Its Level and Pan to the matrix can be adjusted here.

Matrix All Sends View

To work with the sends and assignments from all mixes to one matrix use the Matrix master

Routing screen Fn key Matrix View.

9.10 Working with the Matrix (Qu-24, Qu-32, Qu-SB, Qu-Pac)

A Matrix is a ‘mixer within the mixer’. Channel inputs route to the Groups, Mixes and LR. These mixes can then be routed to the Matrix to provide additional outputs, for example:

• Stereo recording, video or broadcast

• Delay fill speakers

Access the Matrix masters using the Qu mixer top fader Layer, the Qu-Pac Channel screen, or assign them to the Custom Layer.

You can patch the Matrix to Alt Out, AES Out and USB audio.

Each Matrix provides:

• Stereo mixing

• Source send Levels, Pan and Assign

• Master Fader and Mute

• Output Balance

• PEQ

• GEQ

• Compressor

• Delay

• FX Insert

Assign all channels on or off to a mix, or set all sources pre or post-fader.

9.11 Audio Groups

The Qu-24 provides two stereo audio groups in addition to the 10 mixes. Qu-32, Qu-SB and Qu-Pac provide 4 stereo groups. Groups are not available on the Qu-16.

Firmware V1.8 introduced Group Mix Mode. Groups can be configured as conventional stereo audio sub-groups or as additional stereo mixes. By using groups in Mix mode the Qu-24 can provide up to 4 mono and 5 stereo mixes. The Qu-32, Qu-SB and Qu-Pac can provide up to 4 mono and 7 stereo mixes.

Select a group master Sel key while the Routing screen is active.

Adjust the Output Balance between Left and Right Group sockets.

Choose the Group Mode for Group or Mix operation. The reset default is Group mode.

 Current settings will be reset when changing

mode. Confirm ‘Yes’ in the popup that appears.

Group Mode - Touch the Group mode button to

set operating mode as a stereo Audio Group. This provides routing that follows the channel pan control. You can assign combinations of channels and FX returns to a group. Groups can be routed to LR or any Mix to create sub-groups. Groups can be mixed to the Matrix (not available on Qu-16).

Selecting Group mode resets all assignments off.

Group Settings lets you quickly assign all channels on or off to the group as a starting point.

The Grp Processing screen identifies mode below the name box.

The Master strip Grp Mix select buttons illuminate purple when active in Group mode. Select a Grp mix and assign sources to the group as shown below.

Mix Mode - Touch the Mix mode button to set

operating mode as a stereo Mix. This provides channel send levels, dedicated pan, assignments, pre/post and source selection to the mix. You can assign combinations of channels, FX returns and groups to a mix. Mixes can be mixed to the Matrix.

Group Settings lets you quickly assign all channels on or off, and pre or post fader to the mix as a starting point. Use the Channel Source drop-down menu to choose the point in the signal path to send to the mix.

9.12 Working with the Groups (Qu-24, Qu-32, Qu-SB, Qu-Pac)

Choose whether you want the Group to operate as an audio group or a stereo mix. Go to the Grp master

Routing screen.

Changing mode resets the associated parameters.

Audio Group (default)

CH (mono) and ST (stereo) input channels and FX returns can be routed to groups. Group routing follows the channel faders and pan. They do not have send levels.

You can use a Group to combine several channels for single fader level control to a separate stereo output, or sub mix to LR, Mixes and Matrix, or to apply processing to several channels, for example:

• Stereo drum sub mix

• Compressor over several backing singers

• Single EQ over several lavalier microphones

• Grouping signals for recording or ME monitoring

• Grouping channels for ducking

• Grouping channels for AMM master level control

For sub mixing – Assign channels to the Group instead of LR, then assign the Group to LR.

Access the Group masters using the Master Strip Grp

Mix keys. The keys illuminate purple when in Group

mode.

Stereo Mix

Groups can become stereo mixes with send levels and dedicated pan. They behave the same as Mix5-6, 7-8 and 9-10. Mixes can route to the Matrix. Mixes cannot be routed to LR or other mixes.

You can use this to expand the number of stereo mixes available, for example when you need more monitor mixes or are working with more than 3 stereo in-ear systems.

Access these Mix masters using the Master Strip Grp

Mix keys. The keys illuminate blue when in Mix mode.

Group mode provides:

• Stereo routing

• Source Assign to Group

• Master Fader and Mute

• Output Balance

• Routing to LR, Mix and Matrix

• PEQ

• GEQ

• Compressor

• Delay

• FX or Ducking insert

Mix mode provides:

• Stereo send Levels and Pan

• Source Assign to Mix

• Source Pre/Post fader select

• Channel source signal point

• Master Fader and Mute

• Output Balance

• Routing to Matrix

• PEQ

• GEQ

• Compressor

• Delay

• FX insert

Qu Mixer Reference Guide 43 AP9372 iss.10

9.13 Mute and DCA Groups

The Qu mixer provides 4 Mute Groups and 4 DCA Groups. These let you control the levels of groups of channels or mixes.

Mute Group – Provides a single master Mute key to mute or unmute all channels

assigned to the group. This is similar to pressing the Mute keys of all assigned channels at the same time. All channel pre-fade and post-fade sends are affected. This means that sends to FOH (LR mix), effects and monitors will all be turned off when the assigned Mute Group is muted using its master key.

Examples - Mute Groups provide a quick way to mute multiple channels during band changeovers, groups of instruments when they are not being played, or to turn off effects such as reverb when the performer is talking between songs.

DCA Groups – A DCA (Digitally Controlled Attenuator) provides remote control of the

levels of the channels assigned to it. Unlike a stereo Group, audio does not pass through a DCA Group. Instead, the audio levels are controlled at the channels by information sent from the DCA master.

The DCA master Fader adjusts the level of assigned channels at their channel fader point and before the Pan control. This means that post-fade levels to the LR mix and effects are adjusted. Pre-fade monitor sends are not affected. The fader adjusts from fully off to +10dB boost. A channel can have a maximum +10dB boost including its own fader and control from any assigned DCA group faders. When a DCA fader is at its ‘0’ position it has no effect on the channel levels. This is the typical starting point when working with DCA Groups.

The DCA master Mute key behaves the same as a Mute Group master. It affects all pre-fade and post-fade channel sends including LR, effects and monitors. DCA Mute keys can be used as additional Mute Groups simply by setting their master faders to ‘0’.

Examples – DCA Groups provide convenient single fader level control of multiple channels such as drums, backing vocals, stage and radio mics.

The following sources can be assigned to Mute Groups:

• Mono and stereo Input Channels

• FX Send masters

• FX Return channels

• Mixes 1-10 and LR

• Stereo Groups (not Qu-16)

Matrix masters cannot be assigned to Mute Groups.

Assigning one source to many Groups

Press the source fader strip Sel key and select the Touch Screen Routing screen.

Open the Mute/DCA Group Assign tab. Use this screen to assign the channel to any combination of the Mute and DCA Groups.

A green tick next to a Mute Group button indicates that its master is available on a SoftKey.

3. The Qu-Pac provides access in the Channel /

DCA, Mute screen.

4. You can assign any combination of DCA Masters to fader strips in the Custom Layer. Do this using the

Setup / Control / Custom Layer screen.

5. Assign and use one or more SoftKeys as DCA Group Mute keys. Any DCA Group mute can be assigned to any Soft Key.

6. Use the Qu-Pad iPad app DCA Group strips.

The Mute key will flash red if the channel is muted by a Mute or DCA Group.

A short flash shows it is muted by the group only. A long flash shows it is muted by its Mute key and a Mute or DCA group.

Start with the DCA Master level set to 0dB. At this setting it has no effect on the channel levels. Raise or lower the master level to adjust the post-fade levels of all sources assigned to the DCA Group.

DCA Groups can be used as additional Mute Groups when their masters are set to 0dB.

 If there is no signal when you raise a channel fader

check that it has not been turned down by any DCA master it is assigned to.

10.4 Home Screen – User

Three User Profiles are available to protect selected functions and restrict user access, for example for volunteer operators in houses of worship, or guest engineers visiting venues. The Admin user has access to all functions and can set permissions and allocate passwords if required for the other users.

You can log in as one of 3 Users with different permissions:

• Admin – Full access to all functions. This is the

factory default and normal setting when User Profiles are not needed. Admin can set the passwords and permissions for the other users.

• Standard – Operation only. The user is locked out

of setup. Admin configures the channel/mix access, layout, patching and scene range to be allowed for the day-to-day or guest operator.

• Basic – Faders and mutes only. This is for very

simple level control. Admin can set access to none or a range of scenes for recall only.

The Basic User is given access to fader and mute control of the LR mix only. They can recall scenes if a Scene Range has been set.

The Standard User does not have access to any Setup functions including AMM setup, and can be blocked from certain mixes and routing control. They have full access to scenes within the specified range.

Access to mixes

Allow or block access to the Mix key Pre/Post and routing assignment.

Block access to the

10.8 The FX

Qu features 4 internal stereo FX (effects) processors. Each can be loaded from a library of different effects types and presets. These are the same as found in the flagship Allen & Heath iLive digital mix system and are based on emulations of popular industry standard effects.

The FX screen

Press the FX key next to the Touch Screen to open the

FX screen. You work with the FX in the same way you

would with a traditional outboard rack. Start with an empty rack as shown here. Each of the 4 FX has a rack slot. Touch the tabs at the top to select each slot.

Library – Press the Fn key to open the Library page. Select Factory or User library and scroll through and select the FX type you wish to load into the rack. The effects are arranged in types on the left with available presets for each in the right hand window. Touch Recall to load the FX.

Listen to and experiment with the different presets and their parameters available.

FX types

Reverb – This is the most popular effect in live sound

mixing. The SMR Live (Spatial Modelling Reverberator) features 4 fully configurable spatial models - Classic, Hall, Room and EMT plate. Each of these use different reflection and decay algorithms to add natural sounding space to the dry signal whether subtle small room echo, vintage vocal plate or a massive arena. Reverb can make a vocal sound spacious and smooth in the mix or add body to an instrument such as acoustic guitar or flute. There are plenty of factory presets available. The 4 buttons at the top control the main parameters if you wish to make adjustments. HF and LF cut shape the response, and Expert opens up a host of parameters for fine control if you wish to experiment further. You also have the 4-band PEQ available in the FX Return channel processing.

Delay – Generates separate left and right tap delay outputs from the input. Delay time can be dialled in using the screen rotary, tapped on screen or tapped using a SoftKey. The left and right delay taps can be linked to produce a mono effect. Feedback adds regeneration for a repeating echo effect. Set a short delay time around 80 to 160ms for the classic slapback effect.

ADT - An Automatic Double Tracking module capable of creating short echo/chorusing, classic double tracking and ‘slapback’ tape delay loops. It includes a stereo width enhancer and auto panning within the stereo field. The ADT is perfect for creating classic doubling effects, thickening programme on stage or developing a stereo sound field as an alternative to chorusing.

Chorus - Chorus derives from the late 80’s where different stereo field creation techniques influenced the sound of each chorusing unit. Chorus recreates the classics using 3 stereo-field emulations. These emulations can be switched in any combination creating many different stereo fields.

Symphonic Chorus - A faithful emulation of the 80’s

classic chorus effect. Simple to use and frequently requested. The unit has just two controls, Frequency and Depth controlling the rate and delay range of the stereo modulator. The unit produces a rich, lively and wide chorus sound with a suggestion of very mild phasing / flanging. Live engineers commonly use this for thickening vocals and strings and creating a spatial sound from a mono source. This has led to two factory presets ‘SymphonicVox’ and ‘SymphonyStrings’.

Flanger – Qu provides three classic flanger effect emulations – ‘Ambient’, ‘Vintage’ and ‘Wild’. During research of classic pedal flangers we found numerous LFO modulators and stereo splitting techniques. We implemented them all. For classic deep flange set Stereo Split and Stereo Spread off, pick triangular modulation, Vintage type and adjust Depth and Regeneration.

Phaser - A classic 12 stage emulation producing rich textured phasing with plenty of control. You can control the number of stages, feed forward and feed back, and ‘zero’ depth manual mode to manually sweep the Phaser using the offset control.

Gated Verb- An accurate emulation of the popular 80’s Gated Reverb plus two other variants called ‘Panned’

and ‘Powerbox’. The user interface gives instant

access to Lo-cut Hi-cut decay spectrum filters and the gate envelope controls - predelay, attack, hold and release.

Patching the FX

Touch the top right tab to select the Back Panel view. Open the option list to select the type of FX patching. Touch Apply to confirm any changes:

• Mix>Return – Known as a ‘system effect’ this

uses a bus to Send a mix of the channels to the effect, and a dedicated stereo FX Return channel

to add the ‘wet’ effect to the ‘dry’ original sound.

This is used for effects such as reverb and delay. Choose which mix bus to use as its input. For the Qu-16, FX1 and FX2 have dedicated buses. If you want to use FX3 or FX4 as another system effect you could patch one of the Mix1-10 buses as its input.

• Ch>Return – This is similar to a Mix>Return

system effect but fed from one channel rather than a mix of channels. It uses the assigned input channel Direct Output as its source. Examples include a vocal channel delay, gated verb on a snare, or chorus added to guitar.

• Insert – Here the effect is patched in line with an

input channel or mix master. It is switched in or out using the channel Insert switch. Inserted FX provide a Dry/Wet control to balance the effect with the original signal.

FX processing view

Press an FX Send or Return strip Sel key while the

Processing screen is active to view and work with its

parameters. Touch the top of the screen to open the PEQ view and adjust its return channel equaliser.

10.9 Working with FX – Adding vocal reverb:

• Press the FX key to open the FX screen. Touch to select FX1.

Press the Fn key to open the Library page. Touch ‘Factory’. Recall a Reverb into the FX1 slot if one is not already loaded. Open the Back Panel view and check that FX1 is set for Mix>Return with FX1 as its input.

• Start by turning up a vocal channel fader while the master

strip LR mix is selected to hear the signal in the main PA mix.

• Select the top layer to view the FX Return channel strips. Set

these faders to their ‘0’ position and check they are unmuted to ensure the effect signals will be returned to the main mix.

• Press the FX1 Mix key. The master strip now presents the

FX1 Send master fader and controls. The channel faders move to show the sends to FX1.

• Press the master strip Sel key to view the FX1 parameters on

the screen. Press the Fn key to access the library.

• Set the master strip fader to its ‘0’ position and check that it is

unmuted to ensure the channel sends will be sent to the FX.

• Move the vocal channel fader to adjust its send level to the

selected FX. This is similar to turning an Aux send knob on an analogue mixer to feed an outboard effects unit.

• You should now hear the reverb added to the dry vocal

signal. Adjust the send fader for the amount of reverb you want. You can also send other channels to the reverb by turning up their send faders, for example backing vocals and instruments.

• When done, remember to return the faders to the main mix by

turning off the FX1 Mix key or selecting the LR key.

• You can assign the FX sends or returns to a Mute Group if

you want to be able to turn off all the effects with a single key, for example between songs.

• You can assign a SoftKey as a tap tempo key for a delay

effect. This lets you quickly tap in the beat for a vocal delay without the need to open the FX screen.

Use the FX Library to recall different effects types and presets, or to store your own parameter settings as User presets. Listen to their effect on different signals and experiment with their levels and settings so that you can use them as a creative tool while mixing.

Press the Setup key next to the Touch Screen to open the Setup screens.

Touch the top tabs to access the different categories of setup function. Touch the tabs below to open up the related options available.

Dimmer – Hold down the Setup key and turn the screen rotary to adjust the screen and surface LED brightness.

The Qu mixer always powers up with full brightness.

11.1 Audio Setup - PAFL

Choose how you want PAFL to work:

Additive mode – Select to listen to more than one channel at a time. Pressing a PAFL key adds to the previous selection. When off, the mode is Auto-cancel to listen to one channel at a time where pressing a PAFL key cancels the previous selection.

Input/Output PFL (pre-fade listen) – Monitor the signal before the fader, for example to check it and set its gain before you bring up the fader. This is the default.

Input/Output AFL (after-fade listen) – Monitor the signal in stereo after the fader and pan so that you can hear its contribution and position in the LR mix.

Sel follow PAFL – Link the Sel switch so that pressing PAFL automatically selects the processing for that channel.

PAFL follow Mix – With this option turned on, the Master strip PAFL will follow the active Mix selected using the Mix keys. This applies only if PAFL is first selected using the Master strip PAFL key. Default for this option is On.

LR to PAFL – Routes the main LR mix to the monitor when there is no PAFL selected.

PAFL Delay – Delay the monitor to time align it with the acoustic sound from the source when the mixer is a long distance away from the stage. Start with 1ms per foot.

PAFL Trim – Attenuate the PFL (pre-fade) signal by up to 24dB to match it with the average AFL (after-fade) signal which is often much lower than PFL. Default for this option is 0dB (no attenuation).

Momentary Latch option - Press the Fn key to open the Options screen to access the Talk option:

Option Off = Talk key is momentary action only. Press and hold to talk.

Option On = Talk key latches on or off when you press it quickly. It becomes momentary when you press and hold it for longer than 0.5 second.

Select this option when you are working with a switched talkback microphone and therefore want Talk to be permanently selected.

11.3 Audio Setup –Signal Generator

Set up and assign the Signal Generator to test loudspeakers and align levels between equipment.

Source – Touch to open the list of sources available:

• Sine – Pure tone with adjustable frequency. Set to

1kHz and use meters to match equipment levels.

• White Noise – Equal energy per Hz.

• Pink Noise – Filtered white noise for equal energy

per octave. This is a good source to use for testing loudspeaker drivers and phase. Its response matches the way we hear frequencies.

• Band-pass Noise – Pink noise filtered around a

frequency which can be swept from low to high.

Level – Start with the level set low to avoid unexpected loud sounds when you assign to the mixes.

Mute – Turns the signal off.

Assign – Touch to toggle the assignments to the LR

and Mixes 1-10 on or off. Assignment to the Groups and Matrix is not available on the Qu-16.

 To avoid noise in the system remember to turn the

assignments off when you have finished using the generator.

 The Signal Generator is disabled when Talk is

active (green T symbol in screen toolbar). If you want to use the generator make sure that Talk is not active.

Qu Mixer Reference Guide 63 AP9372 iss.10

11.4 Audio Setup - Automatic Mic Mixer (AMM)

An Automatic Mic Mixer provides automatic level control of multiple microphones for spoken word applications, for example conferences and discussion panels involving several participants each with their own mic around a table. This improves intelligibility and can reduce the risk of feedback by dynamically reducing the levels of mics which are not being spoken into. Once set, the AMM needs little or no change at all whilst still allowing the engineer to maintain absolute control of the mix.

The AMM is intended for speech applications not music.

Up to 16 channels (CH1-16 on all Qu models) can be applied to the AMM.

The AMM affects post-fade channel sends to LR, the mixes and FX. It does not affect pre-fade sends such as monitors. It does not affect Direct Outputs.

AMM settings are stored in Scenes.

The AMM is located in the Setup / Audio / AMM screen. It can also be accessed using the Qu-Pad app AMM item in its Custom Strips.

How it works

This diagram shows the signal flow for AMM detection and post fader gain control:

The AMM takes control by first setting each assigned channel fader to '0' (0dB unity gain), thus effectively passing the signal unaffected through the fader. It then uses its own post-fade gain element to make its automatic level adjustments before sending it to the mix. It is typical to leave the faders at '0', but they can be adjusted if the engineer wishes to make additional post AMM level changes manually to adjust the relative balance between mics in the mix and their contribution to the gain sharing (when follow fader is on).

The AMM determines when microphones are open (detecting a level or speech). It analyses the channel signals at their post-Gate point. The PEQ, Comp and fader do not affect AMM signal detection.

Signal detection uses a sidechain filter to filter out sounds outside of the speech frequency range. This can be set to prevent false triggering by ambient noises in the room.

The AMM uses the Qu ‘D-Classic’ constant gain sharing algorithm to dynamically adjust the gain for each mic proportional to its input level and priority setting. Louder signals will receive more gain in the mix while quieter mics receive less and the overall gain remains the same. Mics set for higher priority will get a larger proportion of the gain.

When no one is talking the gain sharing ensures that background ambience is maintained.

AMM Setup - Set High Pass and Low Pass filters for

the input open mic detection to cut off frequencies below and above the normal speech range that may cause false triggering of the mics. Choose whether you want the signal used by the mix calculation to be affected by fader position.

Press the Fn key to open the Setup screen and access the sidechain filter and follow fader options. The reset default settings are 250Hz and 5kHz, with follow fader off.

Scenes and the AMM

AMM settings are stored in Qu Scenes. These can be blocked from Scene recall using the Scene Filters.

Go to the Scenes / Global Filter screen to block or allow AMM settings from all scene recall. Use the per scene Filters to block the AMM from individual scenes.

User Permissions and the AMM

As the AMM is accessed in the Setup / Audio screen it is always blocked from the Standard and Basic users. It would be unusual to allow users other than Admin to set up an automatic mic mixer. However these users can still view but not change the AMM settings in the Setup screen.

Priority Level – For each channel you can set a priority 'level' which will offset the amount of gain going into the mix calculation and therefore give a higher or lower artificial gain to that channel. This is a variable slider with a range from -15dB (low priority) through 0dB (no offset) in the middle to +15dB (high priority) at the top. For example, priority can be used to give the chairman or main speakers a greater share of the gain when several people are talking, or to allow override of audience question mics. Start with all Priority controls set to 0dB (mid position).

AMM In/Out – You can switch the AMM in or out to hear its effect on the mix. Start with it switched In and all channels turned OFF.

Gain activity meter block – These level meters give you a real time overview of the AMM gain distribution for all 16 channels. They light for channels switched ON. Touch the left or right of the block to bring CH1-8 or CH9-16 into the main view below.

ON/OFF – Touch to turn on the channels you want to be affected by the AMM. The

AMM sets the channel fader to ‘0’, takes over

gain control and lights the gain meter.

 We recommend you first turn down the

mix master fader to avoid unexpected loud sound in the PA if the gain structure has not yet been set for the room.

Gain Meter – Dynamically shows the gain applied by the AMM to each channel. You can see how the gain is shared when different combinations of mics are active.

Gain range shown is -25dB to +5dB.

The top of the light grey section shows the 0dB point where the AMM has no effect on the gain. All meters would read 0 when the AMM is switched out. One meter would read 0 it was the only channel turned on in the AMM.

Qu Mixer Reference Guide 65 AP9372 iss.10

11.5 Working with the AMM

Set up and position the microphones - It is best to use the same type

of microphone and position them so that the speaking participants are not too close or too far from each mic. To avoid false triggering and phasing set the distance from each voice to mic to be closer than the distance between the mics. The distances from each mic to voice should be similar for consistent operation.

 Start with the mix master fader turned down – The AMM takes

over level control and opens the channel faders to ‘0’ position. If the

master fader is up and the system gain structure not correctly set you could get a sudden loud microphone level in the PA resulting in possible feedback or audience distraction. Keep the master fader down until you have set the channel mic gains as described below.

We recommend you use a DCA Group or an Audio Group (not available on Qu-16) for master level control of the AMM channels if you have other sound sources also routed to the PA. This would give you independent master control over all the speech mics relative to the other sources. An Audio Group could also allow quick EQ or compression of all speech mics. If you use an Audio Group remember to unassign the AMM channels from the LR mix.

Use PAFL to set the mic preamp gains and processing – You could start by recalling the Channel Library V:Speech preset. Use the meters and headphones to check audio level and quality. Set gain for the loudest speech expected. Gain may need to be set quite high for quiet speakers who are not close to the microphones. It is important that average speech level reads high enough on the channel meter to correctly trigger the AMM.

Adjust the channel HPF and PEQ to tailor the sound for speech – Listen using headphones and filter out low frequency noise. Set the EQ for speech intelligibility. A good starting point is HPF around 180Hz.

Assign the AMM - Switch the AMM In and assign the speech mic channels ON. The associated channel faders will jump to their ‘0’ unity gain position (fully open). Slowly turn up the group or mix master fader. You should start to hear the microphones in the PA.

Test the AMM operation – View the AMM gain meters and listen to check each mic in turn takes gain priority when spoken into. If the AMM is being triggered by background noise make sure the participant is speaking close enough to the mic, or try adjusting the AMM sidechain filter. Use individual channel or group EQ to adjust the frequency response for best speech clarity and to reduce the risk of feedback.

A few tips for working with the AMM

• It is most important that the mic preamps are correctly set for

similar gains and healthy meter readings at expected speaking distance.

• Ring out the mics in the PA to ensure you have good gain before

feedback.

• Try to leave the channels faders at ‘0’. If you need to adjust them

first check that the mic preamp gain is correctly set.

• If any mics are not being used then make sure they are muted or

turned OFF in the AMM.

• Experiment with the Priority control to give more gain to a more

important speaker. Try to keep most set to their centre 0dB position.

• If you are controlling the AMM using the Qu-Pad app you could set

up a Custom Layer with just the assigned mic channels and the AMM strip. This means you can quickly access the AMM settings and mic channel gains and processing.

Qu Mixer Reference Guide 66 AP9372 iss.10

11.6 Control Setup – Custom Layer

The Qu-16, Qu-24 and Qu-32 mixers provide a custom fader layer. The Qu-Pac does not have faders and provides a custom Select key layer (see below).

The Custom Layer can have any combination of channel, FX, master and MIDI strips assigned to its faders. Faders can be left unassigned.

This lets you arrange the faders you are using for your show into one convenient layer, or use the Custom Layer to control your Digital Audio Workstation (DAW).

The screen presents an assignment button for each fader. Touch a button and then turn the screen Rotary to scroll through the available strips.

Use the Fn key ‘+1’ function to quickly assign strips in sequence.

DAW control – When working with a DAW (Digital Audio Workstation) it is typical to assign all faders as MIDI strips so that the Custom Layer can be used to control the audio tracks within the DAW.

Touch button 1, turn the rotary until it displays ‘MIDI’, then press Fn key ‘+1’ to quickly assign the other strips for DAW control.

Turn on the ‘Custom layer only’ option if you want to lock out the two standard layers and let the operator work with just the Custom layer.

Use the space provided to label the custom strips.

Qu-Pac Custom Select Layer

The 16 Qu-Pac front panel Sel keys can be user assigned to any combination in a similar way to the custom fader layer of the other Qu models. This is a powerful feature for quick mixing from the front panel.

The reset default is CH1-16 assigned to the 16 keys.

 Custom Layer assignment is stored in scenes. They are blocked

from Scene recall by default. If you want these settings overwritten

when scenes are recalled then unblock the ‘Custom Layer’ item in the

Global Filter. Use the Scenes / Global Filter screen.

The following strip types are available:

X Unassigned

CH Mono input channels

ST Stereo input channels

FX Ret FX returns

FX Send FX sends

Mix Mix masters 1-10

LR Main LR master

Grp Stereo Groups (not Qu-16)

MTX Stereo Matrix (not Qu-16)

DCA DCA Group master

MIDI MIDI DAW control

To select the Custom Layer

Press both Layer keys together.

Qu Mixer Reference Guide 67 AP9372 iss.10

11.7 Control Setup - SoftKeys

Qu-16 provides 4 SoftKeys. The Qu-24 and Qu-32 provide 10. Qu-Pac provides 15. These are called

‘Soft’ because they can be assigned to different

functions by the user.

Function – Touch the box to open and choose from the list of available functions. Touch Apply to confirm the changes.

 SoftKey settings are stored in scenes. They are

blocked from Scene recall by default. If you want these settings overwritten when scenes are recalled then unblock the ‘SoftKeys’ item in the Global Filter. Use the Scenes / Global Filter screen.

Unassigned – The SoftKey does nothing.

Channel Mute – Assign any channel, FX or

mix Mute to a SoftKey.

Mute Group – Becomes the Mute master for the assigned Mute Group. This is the factory default setting for SoftKeys 1-4.

DCA Mute – Becomes the Mute key for the assigned DCA Group. You could use these as extra Mute Groups if you set the DCA master level to 0dB.

Tap Tempo – Use the SoftKey to tap in the time setting for Delay FX. Choose L, R or L+R (both to follow the same tap).

Recall Scene – Instantly recalls the scene number assigned to the SoftKey.

Scene Store Current – Instantly stores the current mixer settings to the last recalled scene. This is shown in the ‘Curr:’ bar.

Scene Recall Go – Instantly recalls the Scene shown in the ‘Next:’ bar.

Scene Next – Advances to the next scene in the list.

Scene Previous – Steps back to the previous scene.

PAFL Clear – Set a SoftKey to clear any active PAFL

keys. The SoftKey lights to show when a PAFL is currently selected.

Qu-Drive – Set SoftKeys as transport controls for stereo and multitrack recording and playback. Touch and scroll using the rotary to select the transport control required.

MMC – Set SoftKeys as transport controls for MIDI.

DAW Bank Control – Set SoftKeys as DAW Bank

up/down controls.

Talkback – Assign a SoftKey as the Talk switch. This is useful when using the Talkback function on Qu-Pac which does not have a dedicated Talk key.

Qu-24 shown

Set Auto Increment if you want to step through your scenes using a single key. This recalls a scene, then advances to the next available scene ready to recall it when the key is pressed again. For example, step through your cues in a theatre show. Auto-increment skips blank scenes.

Qu Mixer Reference Guide 68 AP9372 iss.10

11.8 Control Setup - Network

Use this screen set the TCP/IP address for the Network port and the name used to identify the Qu mixer on the network.

It is important that the network address is compatible with the addresses of equipment connected to the port, for example a laptop providing MIDI control of mixer parameters, or a wireless router providing remote control using the Qu-Pad iPad app.

DHCP – Enable this if the connected device has DHCP capability and is therefore able to automatically allocate a compatible IP address to the mixer. This is the factory default and is the typical setting for connecting to a wireless router used to interface with an iPad.

For manual setting of the network address, enter compatible IP Address, Subnet Mask and Gateway settings.

Unit Name – Enter a name with up to 15 characters to identify the Qu mixer on the network. The default name is the model number, for example, ‘Qu-16’ or ‘Qu-24’.

11.9 Control Setup - MIDI

The Qu mixer can send and receive MIDI messages for remote control of many of its functions. It also provides MMC transport control from this page, or assigned to SoftKeys. The Qu uses two MIDI channels, one for Qu mixing functions, the other for DAW control using the Custom Layer.

MIDI over USB – The rear panel USB B port allows direct connection to Apple® Mac computers running OSX 10.6 or later. This carries MIDI and audio streaming. USB B is the recommended connection for DAW and other computer based MIDI control.

 USB MIDI is supported natively by the Mac so no

driver is needed. A driver for Windows® computers can be downloaded from the Allen & Heath web site.

MIDI over TCP Network – The rear panel Network port is used for connection to a Wi-Fi router to work with an iPad running the Qu-Pad app. The app uses these MIDI messages to remotely control the Qu mixer. Alternatively, the Network port can be used with a touch panel or other remote controller that allows configurable MIDI over a TCP/IP port.

 Qu currently allows only one TCP connection at a

time over its Network port.

MIDI channel number – The Qu uses two MIDI channels, one for mixing functions and the other for DAW control. Choose and Apply the mixing function MIDI channel. DAW control will use the next MIDI channel above that.

MIDI control available:

• Mutes

• Faders and Pan

• Audio Group Assign (not Qu-16)

• Mix and FX Sends, Pan, Assign, Pre

The Qu-16 provides 24 patchable USB outputs. The Qu-24, Qu-32, Qu-SB and Qu-Pac provide 32 USB outputs.

Qu-Drive and USB B streaming share the same block of patchable tracks:

• Qu-Drive Stereo = Track 17-18

• Qu-Drive Multitrack = Track 1-18

• USB B Streaming = Track 1-32 (Qu-16 has 24)

There are two screens:

• Track 1-18 = Tracks associated with Qu-Drive

• Track 19-32 = The rest of the tracks for USB B

Touch the lower left ’19-32’ or ‘1-18’ buttons to navigate between the screens

Touch a button and then turn the screen Rotary to scroll through the available output sources.

Use the Fn key ‘+1’ function to quickly assign strips in sequence.

Once you have chosen the outputs press Apply to accept or Cancel to discard the changes.

CH/ST/Grp source button

Set this to Insert Sends if you do not want the input channel and group USB sends to be affected by the mixer processing (EQ, Comp, Gate, Delay). This sends the raw Preamp and unprocessed Group signals to the USB stream and is the typical setting for live recording.

Set this to Direct Outs if you want the input channel USB sends to follow the channel global Direct Output option. It also sets the Group sends to be postprocessing and post-fader. This is the typical setting for studio recording (working with a DAW).

 The global Direct Output option affects all inputs

and is set in the channel Routing screen.

Output sources are post processing, post fader.

The USB Audio factory reset default patching varies according to Qu model. All ensure that tracks 17-18 = LR post-fader for Qu-Drive stereo recording. The patching can be changed here to suit your requirements.

11.20 Utility – Qu-Drive

This screen lets you check and format a USB device (key or hard drive) for use with Qu-Drive. Once formatted you do not need to format it again.

 Formatting the USB device will erase all current

data on it. If you want to keep this then make sure you archive the data elsewhere first.

For reliable performance you must first format your USB device using the Qu mixer Format utility. Once formatted, use this with Qu only. Do not use the device for other applications.

Plug in the USB device. Wait for the mixer to read the drive. The status window displays information about the USB device:

File system: OK (no need to format) File system: Unsupported (you need to format it)

Touch Format to start formatting. When complete, wait a few seconds for the mixer to read the key. If successful the status window will display ‘OK’.

 Do not remove the USB device or turn off power

until formatting is complete.

 Qu-Drive audio recording and multitrack

playback require the USB storage device to support high sustained transfer rates. Not all USB devices will guarantee flawless performance.

To find out more please refer to the ‘Understanding

Qu-Drive and USB’ document in the Qu Knowledgebase on the Allen & Heath web site.

Once formatted on the Qu mixer, use the USB device with the mixer only. Do not use it for other storage and applications.

12. USB Audio Interface and DAW Control

The Qu mixer can stream audio and send MIDI messages to and from an Apple® Mac or Windows® PC computer via the rear panel USB B port. This lets you work with a DAW (Digital Audio Workstation) running on your computer. The Custom Layer can provide MIDI control faders and keys. You can work with the standard Qu MIDI messages or download the Allen & Heath DAW Control driver to convert these into one of the popular HUI or Mackie Control protocols.

12.1 Audio streaming

Apple® Mac USB audio streaming with Qu MIDI message control is supported

natively by the Mac so it does not require any driver.

Windows® PC USB audio streaming with Qu MIDI message control needs a driver.

Download and install the Allen & Heath Qu Windows Driver. Power up the Qu mixer, connect its rear panel USB B port to the PC, run the installer and follow the instructions on the screen. The driver is ASIO 2.2 compliant and supports standard WDM/DirectX Windows interfaces including MME and DirectSound.

Connect the Qu mixer to the computer – Plug a

suitable cable into the rear panel USB B port.

Stream audio to the computer – Audio is sent via the rear panel USB B port. Go to the Setup / Output

Patch / USB Audio screen to choose which Qu

outputs to patch to the USB stream.

CH/ST/Grp source button

 The global Direct Output option affects all inputs

and is set in the channel Routing screen.

 Most DAWs allow flexible patching and routing of

tracks to/from any interface I/O. However if you are using iTunes, QuickTime or similar for playback to the mixer, the stereo output will default to the Qu Input CH 1 and 2. You can change this manually on the Mac, and use the latest version of the Qu Windows Driver on the PC.

12.2 DAW Control

Set the Qu mixer MIDI channel number – Use the

Setup / Control / MIDI screen to set the Qu MIDI

channels. Qu DAW control uses its own MIDI channel. This is the next number up from that set for the other Qu MIDI messages. Qu defaults to Channel 1 for standard messages and Channel 2 for DAW control.

Set the Custom Layer for fader control – Use the

Setup / Control / Custom Layer to assign the faders

as MIDI strips. MIDI Strip controls transmit and receive CC and Note on/off messages. Refer to the Qu MIDI Protocol Document on the Allen & Heath web site for further information.

The MIDI messages can be manually assigned or ‘learned’ by most DAWs. However if you wish to convert the standard Qu MIDI messages into the HUI or Mackie Control protocol, download and install the Allen & Heath DAW Control driver. Follow the setup instructions in its Help Manual.

 DAW Control for Windows will be released shortly after V1.9 firmware release.

Set the MIDI channel to be the same as the Qu mixer DAW channel. For USB connection select MIDI Ports. Select the MIDI Input and Output ports to be used.

14. iOS Apps for Wireless Control

Two Qu apps are available from the Apple Store: Qu-Pad - Engineer’s live mixing control

Qu-You - Musician’s personal monitor control Qu-Control – Customisable app for install

You can connect up to two iPads running Qu-Pad and up to 8 iPhones, iPads, iPod Touch or Android devices running Qu-You or Qu-Control. The maximum total number of connected devices is 8.

 Refer to the Qu-Pad, Qu-You and Qu-Control Help Manuals for details on their

operation and setup.

Qu-Pad is an engineer's mixing tool giving you the freedom to

walk the room or stage and control the sound right where it is needed. Since V1.9, Qu-Pad gives you control of the live mix and full system setup. Qu-Pad and the Qu console can work together to provide simultaneous control of independent functions, for example one engineer using the console to mix front-of-house sound, and another using the iPad to mix monitors on stage.

Qu-Pad runs on all models of iPad running iOS7.1 or higher. The current version tested at the time of this release is iOS9.



Qu-You provides personal monitor mix control for

musicians and performers on stage. The engineer can still keep an eye on and control each mix at the Qu mixer at any time.

Qu-You runs on Apple iOS devices including iPhone4 or later, iPad, iPad Mini or iPod Touch running iOS7 or later. A version is also available for Android devices.

Qu-Control is a customisable app with up to five

screen tabs and up to 15 control ‘widgets’ per tab. These can be anything from background music source selection to a master zone level or microphone paging. A password for Qu-Control users can be set at the mixer.

Qu-Control runs on Apple iOS devices including iPhone4 or later, iPad, iPad Mini or iPod Touch running iOS8 or later.

Using the Qu-Pad, Qu-Control or Qu-You app

Qu Mixer Requirements - The Qu mixer firmware and app feature release version

number must be the same, for example V1.7 firmware will not run with a V1.8 app. However, the maintenance version numbers do not need to be identical, for example QuPad V1.90 would run with Qu mixer V1.91. Refer to the Allen & Heath web site for more information and to download the latest Qu mixer firmware.

Set up the wireless network – Connect and configure a suitable wireless router as described below. Connect the device to this network.

Start the app and log in to the Qu mixer – The app opens in its Login page. You should see your Qu mixer in the list if it is recognised on the wireless network. Select this and touch Connect. Enter the password if one has been set for Qu-You users at the mixer.

Qu Mixer Reference Guide 82 AP9372 iss.10

Setting up the Qu wireless network

The app sends and receives control data over a wireless (Wi-Fi) network. This requires a wireless router (wireless access point) connected to the Qu mixer Network port.

Choosing a wireless router - For best performance we recommend you use a dual band (2.4 and 5GHz) wireless router (wireless access point) with auto channel selection. A wireless router with auto channel selection automatically sets itself to an available or least congested channel when you power it up.

Setting up the Qu mixer Network - The default setting is DHCP enabled. This is recommended as it means that the mixer gets it network IP address automatically from a DHCP enabled router. Go to the mixer Setup / Network screen to check that DHCP is enabled.

If you choose to use manual network settings then you need to make sure that both the mixer and the router have compatible TCP/IP addresses.

Setting up the wireless router – The default settings of many routers are immediately compatible with the Qu mixer so you should be able to connect quickly. However, if you do experience difficulty or wish to change security settings then you will need to access the router setup utility. To do this, connect the router to a PC or Mac using a wired LAN (network) connection to access its setup menus. Follow the instructions provided by the wireless router manufacturer.

Wireless router DHCP settings - Make sure the router is set for DHCP so that it automatically allocates a

compatible IP address to your control device. This is the default setting for most routers.

Wireless security -To prevent other people accessing your Wi-Fi we recommend you enable WPA/WPA2

encryption. A wireless key (password) will need to be assigned. Make a note of this as it will be needed to log on to the network. MAC address filtering is another method that can be used for security.

SSID - This is the name broadcast by the wireless router to help identify it in the network list you will see in

the device Settings Wi-Fi page.

Positioning your wireless router – It is important that your control device operates within the specified range and in line of sight of the wireless router. Place it high up to avoid obstacles such as people and equipment. Avoid locating it behind pillars or walls, near metal beams or on top of loudspeakers.

Connecting to the wireless router - Make sure the device Wi-Fi is turned ON in its Settings screen. Choose your wireless router from those shown in the Network list. Enter the password to connect to the router. After a few moments a tick should appear to show the device has successfully connected to the wireless network. Check that the icon in the device top toolbar shows good Wi-Fi signal strength.

 To prevent unauthorised control of your Qu mixer we strongly recommend that you password protect

your wireless network.

 The iPad remembers the network settings. To prevent an device connecting again in future without the

password, for example if you have given a guest engineer access your Qu with their own device, select your network in their device Settings Wi-Fi menu and use the 'Forget this network' function.

If you experience connection problems or drop outs – You may suffer interference from other wireless networks or equipment in the area. Try rebooting the router to pick up a different channel, or change its band (2.4 or 5GH).

15.Resetting the Mixer

There are two ways to reset the Qu settings:

15.1 Reset Mix Settings – A starting point for mixing

This button in the Scenes screen resets the mixer to a known starting point for mixing. It provides a quick way to reset the processing, mixes and patching before a show or after another user has finished with it.

All parameters that can be stored in Scene memories are reset to a factory default. Parameters that are not stored in scenes are not affected. This reset does not affect existing scenes stored in the mixer.

If you want to keep your current settings then save these as a Scene before resetting the mixer.

 This reset is not affected by the Global filter and

Safes settings.

Touch and hold the Reset Mix Settings button for 1 second until the confirmation screen appears. Touch Yes to reset the mixer or No to exit without resetting. This ‘resets the board’ ready for mixing:

• All preamps are patched and have nominal mic

gain set and phantom power switched off, a good start for vocal microphones,

• All EQ is switched in and set flat ready to start

adjusting tone,

• Gates and compressors are switched out but have

their parameters set ready for being switched in for applications such as drum gating and vocal compression,

• Channels are assigned to the mixes and FX with

their faders and send levels turned down ready to start dialling into the mix,

• The mixes are set pre-fade and sourced post-EQ,

pre-compressor ready to be used as monitor sends, a common application for the mixes.

• The FX master and return faders are turned up

and default reverbs and delay patched ready for you to hear the effects as soon as you raise a channel send.

• The Mix master faders are turned up ready to hear

sound when you raise a channel send. The main LR master is turned down to avoid unexpected loud level in the PA.

• The Groups are unassigned and their master

faders turned down (not Qu-16).

• The Matrix sends are assigned and their master

faders turned down (not Qu-16).

Creating your own start settings – You

can start by resetting the mixer and then editing the patching, levels and parameters to suit your starting preferences. Name and store this as a Scene, for example Scene 1 “Reset Board”.

15.2 System Hard Reset

A power up reset is available if you need to fully reset the Qu mixer settings and memories. This could be done to clear the system out before sending the mixer to a client, or if you suspect a system problem.

To reset mix parameters before starting a show or sound check, use a Scene or the Reset Mix Settings function described earlier in this guide.

 A hard reset clears all current settings, all Scenes,

User Libraries and User Permissions.

First turn off the system including amplifiers and powered speakers.

To hard reset the Qu mixer - Press and hold the touch screen Reset and Setup keys together and then power up the mixer. Keep the keys pressed for at least 5 seconds while the mixer boots. Release the keys.

The hard reset:

• Resets the current settings the same as using the

Scenes screen ‘Reset Mix Settings’ button.

• Resets non-scene parameters and user

preferences to a factory default.

• Clears scene recall Safes and Filters.

• Clears all memories including Scenes, User

Libraries and User Permissions.

• Resets the Network IP address and the touch

screen calibration.

System hard reset:

• ‘Reset Mix Settings’ default as above

• Input PAFL = PFL, mix = AFL

• PAFL additive mode off

• Sel follow PAFL on, LR to PAFL on

• PAFL trim 0dB, delay 0ms

• Talkback mic gain 27dB

• Sig Gen Pink Noise, unassigned

• Clears all scene Safes

• Clears all Scene memories

• Clears all Scene Filters

• Clears all User Libraries

• Resets all User Permissions

• Resets Network address to DHCP

• Resets touch screen calibration

Hold for 5 seconds while powering up the mixer

16.Specifications

16.1 Installing Qu-16, Qu-24, Qu-32

The following provides information for mixer installation. The Qu mixer can be operated on a flat surface or fitted into a flightcase. The Qu-16 can be mounted in a 19” equipment rack or plinth.

Ventilation - Make sure that air flow around the

ventilation slots at the rear and underside of the mixer is not obstructed. Keep these areas clear when flight casing, installing or operating the mixer.

 Blocking or obstructing the ventilation slots may

cause damage to the mixer through overheating.

Qu-16 Rack Mount Option

A kit of parts is available from Allen & Heath to mount the Qu-16 in a standard 19” equipment case.

Rack kit part number QU-16-RK19

Minimum rack space required is 11U.

 Allow space for the connectors

and cables at the rear.

The rack ears can be fitted without the need to remove the plastic side trims. Simply secure them to the base of the mixer with the 6x M4x8 screws supplied (part number AB0332) using a T20 Torx screwdriver.

Secure the mixer in the 19” rack with

8x M6 screws with plastic cup washers to protect the mixer surface.

Qu-16 = 440 Qu-24 = 632 Qu-32 = 850mm

Qu Mixer Reference Guide 86 AP9372 iss.10

16.2 Installing Qu-Pac
