3. Introduction 3.1 Overview and Features Building on the heritage of the GLD and flagship iLive digital consoles, the Qu presents exceptional performance together with an intuitive analogue style user interface with a motorised fader per channel, knobs and touch screen, total recall of all settings, full input, output and FX processing, USB streaming and hard drive multitrack recording, digital snake capability and remote wireless control using an iPad.
3.2 System Architecture and Processing The following diagrams show the Qu-16, Qu-24 and Qu-32 I/O (inputs and outputs), audio architecture and processing available. The differences between the models and the routing capability of each processing section is illustrated. Refer also to the more detailed System Block Diagrams at the rear of this guide.
3.3 Differences between the Qu models All three models operate in the same way and have a similar touch screen menu structure. The larger models add Groups and Matrix.
16 Mic/Line in 24 out, 22 in USB audio streaming 24 Mic/Line in 32 out, 30 in USB audio streaming 4 Group out Matrix out 32 Mic/Line in Matrix out 8 Group out 32 out, 32 in USB audio streaming 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.
4. Connection Overview The following connections are available on the rear panel of the Qu mixer. The Qu-16 is shown here. AES digital out Lamp Alt out 2Trk out LR main out Analogue Mix outputs Mic and Line inputs Talkback Mic in ST1 and ST2 stereo line in Kensington Lock Cable clamp dSNAKE remote audio Power On/Off Network USB B streaming Mains fuse Mains power input 4.
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. Pin2 = hot Professional equipment provides ‘balanced’ connections for maximum interference rejection over long cable runs.
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.
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.

6. Operational Overview This section provides an overview of the Qu layout and operation to help you get started quickly. The Qu16 mixer is shown here. Touch Screen SuperStrip TouchChannel Screen select Qu-Drive Fader Flip Engineer’s monitor Copy/Paste/reset Function key ( Fn ) Mix assign SoftKeys Layer select Master Strip Fader Strips Mix select Mix keys Channel select Sel key 6.1 Fader Strips The Qu mixer has a group of fader strips, one per channel.
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.
6.2 Channel Naming Qu channels, FX, mixes and groups can be named using the screen keypad. The following can be named: Mono input channels Stereo input channels FX Returns FX Sends Mix LR Groups Matrix Mute Groups DCA Groups Channel names The name is displayed at the top left of the Processing and Routing screens. The name can be edited from the Processing screen. The pencil icon appears when the name is blank. All names are cleared when the Qu mixer is reset or the ‘Reset Mix Settings’ scene is recalled.
6.3 Channel Processing The SuperStrip provides familiar, analogue feel, one function per knob control of channel and mix master processing such as equalisers and dynamics. The Touch Screen displays the parameter values and provides additional related controls while in the Processing screen. This processing is accessed using the fader strip Sel keys.
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: Local – Mic/Line sockets on the Qu rear panel. dSNK – Remote preamps via dSNAKE. Qu-Drv – Playback from USB hard drive. USB B – Audio streaming from a Mac computer. Press the Fn key to open the Source screen.
Peak 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. Other functions in the Preamp section Insert switches an internal FX in or out if one has been patched into the channel. The button is disabled when the insert is not patched. The FX is inserted between the preamp and EQ.
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. 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 a 12dB slope and can be swept from 20Hz to 2kHz. The violet screen curve shows the resulting frequency response.
Use the In key 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.
Press the GEQ Fader Flip key to view and adjust the GEQ on the faders while a mono 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.
6.7 Channel Routing The Touch Screen presents tabs to access the channel assignments and send levels when its fader strip Sel key is selected and the Touch Screen Routing screen is active. The Channel Block Pan control provides quick access to the related mix pan setting for the channel. The Fn key is used to access the Mute Group masters while in any Routing screen. 6.8 Working with the Routing screens Press a fader strip Sel key. Press the Touch Screen Routing key.
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.
Mix Routing Select a mix master Sel key while the Routing screen is active to: Adjust the Output Balance between Left and Right 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. Post-Preamp Gain/Trim Insert Pre-EQ HPF GATE Post-EQ PEQ COMP Post-All DELAY 0 Choose Post-Preamp if you want the sources to the mix to not be affected by any of the channel processing.
6.11 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.
To assign Mute Groups - Select the Mute Group Assign tab, then touch the tab for the Mute Group you wish to assign. To assign DCA Groups - Select the DCA Group Assign tab, then touch the tab for the DCA Group you wish to assign. All sources to that group are shown. The larger Qu mixers present two pages of assignments. Touch the arrow button to navigate between the two pages. Touch buttons to assign sources in or out of the group. Touch the All button to turn all the assignments in or out.
6.13 Using DCA Groups There are 5 ways to access the DCA Groups: 1. All Qu mixers provide DCA master controls in the Routing screen Mute/DCA view Masters tab. Press the Fn key to open this view. Touch a Mute button to mute or unmute a DCA group. Touch a DCA Level box and use the screen rotary to adjust its level. Its value is shown in the box. Fn key 2. The Qu-32 provides dedicated DCA fader control strips on its Master layer. These provide direct access to the 4 DCA groups. 3.
6.14 The Master Strip Qu provides a dedicated fader strip for the Mix Masters. It presents the fader and controls for the mix currently selected using the Mix keys alongside. The sends to the selected mix are presented on the channel faders. They move to show the current settings. This provides a very quick way to access each mix without the need to switch to the Masters layer. Mute key – Press to turn off the mix master audio signal. The Mute key lights red when the audio is muted.
6.15 Working with the sends on faders: Select a Mix - Press a Mix key. The master strip presents the mix fader and controls. The channel faders move to present the sends to that mix. Adjust Send levels – For Mix and FX sends. Move the channel faders. These become the sends to the selected mix. Adjust Send pans - While a stereo Mix is selected, press a channel Sel key and use the Pan control to pan its send in the mix.
7. Touch Screen Mixing Functions The Qu features an 800x480 pixel, colour touch screen for quick and intuitive setup and control of the mix. The Qu-16 and Qu-24 have 5” screens.

The Admin user has access to all functions and can set permissions and allocate passwords if required for the other users. This screen lets you log in as one of 3 Users with different permissions: Admin – Full access to all functions.
7.5 Home Screen – Meters This screen provides a convenient view of all channel, mix and FX signal activity. For optimum performance the loudest signals should read into the yellow. If any red Peak meter flashes then reduce the level of that signal to avoid possible distortion. Increase levels if the meter readings are consistently low. The Qu-24 meters screen is shown here. Qu-32 provides two pages of meters. The Qu-16 does not include Group and Matrix meters. 7.
Patch the source to be recorded using the Setup / Output Patch / USB Audio screen. Touch the track 17 box and turn the rotary to select the left source. Press the ‘+1’ Fn key to increment the right source to track 18, or use the rotary to select an unrelated source. Mono or stereo Channels and Groups can be globally sourced from their Insert Sends (pre-processing) or from Direct Out using this button.
Qu-Drive Multitrack page – This screen presents the controls for multitrack recording to and playback from a USB storage device plugged into the top panel Qu-Drive port. The blue Stop button lights if the USB device is recognised by the mixer. The controls are disabled if not plugged in or recognised.
7.8 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.
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.
7.9 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.
7.10 Scene Memories Qu provides 100 Scene memories. These store and recall a snapshot of all live mixing parameters. Scenes have many applications.
