4. Installing Qu-SB

Rubber feet Gap for ventilation and cables

Free standing – For operating while on a stage
or other flat surface. Make sure the 4 rubber feet are fitted.
– Allow space around the unit for ventilation.
Run the cables to avoid a trip hazard.
The mixer should be transported in a purpose designed padded bag or flight case.
Rack Mounted – For operating while fitted into
a 4U space in a standard 19″ equipment rack or flight case. The front panel is angled upwards to allow easier access to plug in the cables. A gap underneath the unit lets you feed cables through from within the rack.
Rack mounting option kit QU-SB-RK19 is available from Allen & Heath.
– Ensure adequate air flow. Do not block the
rear ventilation slots or the gap underneath the front of the unit.
To save space a `shallow’ case with internal depth of 200mm (8″) or more is recommended.

Fit the rack ears (AA10262) to the mixer using the 2x M4x8 (AB0332) screws per side. Use a Torx T20 driver.

Secure Qu-SB into the rack using the 2x M6x16 screws (AB10301) and plastic cups (AB0345) per side.
The rubber feet do not need to be removed. If you do wish to remove them then unscrew using a Torx T20 driver.

1 Network Port Qu-SB is controlled using an iPad running the Allen
& Heath Qu-Pad app. Connect a wireless router (wireless access point) to this port to set up a Wi-Fi network for the iPad to connect to the mixer. This is described in more detail later in this guide.
2 Footswitch 3-Pole (TRS) jack socket to connect a single or dual
footswitch controller. Its function is assigned by the user, for example to mute effects between songs or set delay tap tempo.
3 dSNAKE Port Use this port to connect a Cat5 cable `digital snake’
to work with remote audio and expand the number of input and output sockets using one of the optional Qu AudioRacks, or connect directly to the Allen & Heath ME personal mixing system letting musicians control their own monitors. Maximum Cat5 cable length is 100m (330′).
4 Qu-Drive Type A USB socket to plug in a USB device such as a
key or hard drive to store and transfer mixer data files (scenes, shows, libraries), and to record or play back stereo or multitrack audio WAV files up to 18 tracks. This port is also used to update the mixer firmware via USB key.
5 USB B Type B USB socket to connect the mixer to a computer to
stream up to 32 channels of audio to and from a computer, for example to record and playback multi-channel audio using DAW software. 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.
6 Firmware Update This recessed switch lets you update the mixer
firmware without an iPad connected. The update procedure is described later in this guide.
7 Network / Factory Reset This recessed switch has two functions:
To reset the Network port IP address if it has been changed and the mixer does not connect to your router, or to completely reset all mixer parameters to factory default and clear all memories. Reset functions are described later in this guide.

8 Mic Input For plugging in low level sources such as microphones
or DI boxes. The preamp uses a balanced XLR socket and has a wide gain range from -5dB to +60dB. 48V can be switched to the XLR for condenser mics and active DI boxes that require phantom power.
Qu-SB provides 32 channels with 16 local input preamps. You can access the additional preamps for the full 32 channels using an optional AudioRack plugged into dSNAKE.
To avoid loud thumps, mute the channel before plugging in cables or
equipment while 48V is on.
9 Line Input For plugging in line level signals. The input uses a
balanced ¼” TRS (Tip, Ring, Sleeve) jack and has a fixed 10dB pad to handle from low to very high level line signals. For unbalanced sources use a mono jack or link ring to sleeve within the TRS stereo jack. Channels can be linked as odd/even pairs so you can use these inputs to directly plug in stereo sources such as keyboards, samplers and media players.
For high impedance, low level sources such as acoustic instrument pickups use DI boxes plugged into the Mic inputs
Plug into either Mic or Line. Do not plug into both on the same
channel.
10 ST1 Input For plugging in a line level stereo source such as a
media player for walk-in music. Uses a pair of balanced ¼” TRS jack inputs with the L input switching through the R socket so that you can also 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.
11 Mix Outputs Balanced XLR line level outputs for mono Mix1-4
and stereo Mix5-6 to 9-10. Connect to nominal +4dBu or 0dBu line level equipment. Maximum output is +22dBu.
12 LR Output A pair of balanced XLR line level outputs for the main
LR FOH mix.
13 MTX1-2 Output A pair of balanced ¼” TRS jack line level outputs
to access stereo Matrix 1-2. You can route any combination of mixes, groups and LR to the matrix, ideal for creating a useful utility mix for stereo recording, broadcast zone sends and more.
Qu-SB provides local outputs for Mix1-10, LR and MTX1-2. You can add more output sockets and access the stereo Group and second matrix outputs using an optional AudioRack plugged into dSNAKE.
14 Headphone Output Lets you monitor any channel or mix signal
within the mixer using the PAFL buttons in the Qu-Pad app. Use good quality low impedance stereo headphones. Adjust the level using the Phones control.
To prevent damage to your hearing start with the Phones level turned
down and avoid listening to loud volume for extended periods.
15 Qu-32 Core Qu-SB is the smallest model in the Qu range but uses
the same 32 channel DSP mix engine as the largest model, the Qu-32. Channels and outputs not available locally at the Qu-SB can be patched from/to sockets on a remote AudioRack via dSNAKE.

6. Connect and Power Up

6.1 Set up the Wireless Network
Qu-SB is set up and controlled using an iPad. This connects to the mixer via a wireless router plugged into the Network port. This sets up a private Wi-Fi network for the mixer.

Qu-SB Network port

iPad running Qu-Pad app

Qu-You monitor app

Wireless router

LAN port

Engineer’s control Musician’s personal monitors

Cat5 cable
iPad Qu-Pad supports models from iPad2 up running iOS7.1 or higher.
Qu apps – You can download the Allen & Heath Qu-Pad mixing control app from the Apple App Store. You can also get the Qu-You app for musicians personal monitor control for iOS devices including iPad, iPhone and iPod Touch, and also for Android devices. These apps are free and can work with any Qu mixer.
The Qu mixer firmware and app versions must be compatible. For
example, V1.8 app will not run with V1.9 firmware. To avoid unexpected version mismatch we recommend you turn off `auto update’ on your iPad. Download the latest Qu mixer firmware from the Allen & Heath web site.
Number of connections Qu supports a maximum of 8x connections including up to 2x iPads running Qu-Pad. The others can be Qu-You.
Wireless router – For best performance use a dual band (2.4 and 5GHz) wireless router (wireless access point) with auto channel selection. Position 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.
We recommend that you change the router SSID (name) to identify your network and set a router password (key) for security.
Power up the router. Wait a few minutes for it to establish Wi-Fi broadcast. Go to your wireless device Settings screen, find and connect to the mixer Wi- Fi network.
The iPad remembers the network settings. To prevent a guest
engineer using their own iPad on your network without password in future, select your network in their Settings Wi-Fi menu and use the ‘Forget this network’ function.
Qu network address – The mixer must have a TCP/IP (network) address compatible with the router. The Qu default is DHCP enabled which means that the router will automatically allocate a compatible address to the mixer when connected. If the mixer address has been changed and the Qu-Pad app does not connect then you can reset it to this default:
While the mixer is on, use a thin pointed object to press and hold the front panel Network Reset key. The indicator will light and after a few seconds flash to confirm the address has been reset to DHCP.

6.2 Connect dSNAKE (option)
If you are using an optional remote AudioRack then connect it with a Cat5 digital snake. Use STP (shielded twisted pair) Cat5e or higher spec cable up to 100m (330′) long. Cable 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.

The maximum number of AudioRacks you can connect is two.
If you are using the Allen & Heath ME personal mixing system then connect it to the dSNAKE, EXPANDER or MONITOR (AR2412 only) port. ME-1 mixers can be daisy chained or you can connect individually via the Allen & Heath ME-U PoE hub. Refer to the ME-1 and ME-U user guides for more information. You can also use the Qu-You personal monitor app running on iOS or Android devices to let musicians control their own monitors.

6.3 Power up the mixer

Important – Before starting, read the Safety Instructions
Sheets packed with the mixer. These can also be downloaded from the Allen & Heath website.
To avoid loud thumps, do not apply or remove power while the
PA speakers are powered.
Always switch the amplifiers on last, and off first.

Switching the mixer on Qu-SB does not have a power
switch. Plug the provided IEC mains cord into the mixer AC MAINS IN socket. Turn power on at the mains inlet if it is not on already. The mixer takes just a few seconds to boot up. It restores its previous settings and audio.
The front panel BLUE Power indicator lights when the mixer is powered.
If you are using an AudioRack or the ME personal mixing system then the yellow dSNAKE Lnk indicator will flash steadily once connection is established.
Switching the mixer off Mute or turn the PA speakers off
first. Turn the Qu-SB power off at the mains socket or simply pull out the IEC mains cord at the AC MAINS IN socket.

6.4 Connect the iPad
The Qu-SB mixer is controlled using an iPad running the Allen & Heath Qu-Pad app. Choose and set up a wireless router as described previously. Settings are stored in the mixer. Audio will continue to run even if the iPad is disconnected.
Connect the Wi-Fi router Position and power up your router. Connect one of its LAN ports to the mixer Network port using a Cat5 cable. The yellow Network Lnk indicator will flash once the link is established.
Connect the iPad to the Qu network Go to the iPad Settings / Wi-Fi screen and choose your router in the NETWORK list. If it is not in the list give it a few minutes for its broadcast to establish. Check that the iPad shows good signal strength.

7. Qu-Start
This section provides a quick guide to get you started mixing with Qu-SB and Qu-Pad. For more information please refer to the Qu-Pad Help manual and to the Qu Mixer Reference Guide available for download from www.allen-heath.com/key- series/qu-series.
7.1 Set a known starting point
To completely reset the mixer you can perform a power up System Hard Reset. Only do this if absolutely necessary. This clears all Scenes, User Libraries, User Profiles and passwords and resets all settings to factory default. See section at end of this guide.
To zero the board as a start for setting up a new session or event you could use the Reset Mix Settings function on the Scenes page. This is a special Scene that resets all current mix parameters to factory default to give you a clear starting point to mix. It does not affect the memories and system settings and preferences.
This reset is not affected by the Global Scene Filter nor channel Safes. It also resets the Global Filter and clears the Safes. Touch and hold the Reset Mix Settings button for 2 seconds and then confirm.
To set your preferred starting point you could set up and store your own template Scene and keep this on USB device as a backup to load into this and other Qu mixers you may use.
7.2 Prepare the mixer for your session
Choose the channels sources You can choose one of 3 sources for each mono and stereo channel Local socket (rear panel, dSNAKE socket (remote IO), or USB (playback). The reset default is the Local input sources.
To change channel sources use the Processing screen Preamp tab Source button. If you are using dSNAKE you can patch any remote socket to any channel. If you are using USB select either Qu-Drive or USB B as the global source.
Name the channels and masters Working from your plot sheet, use the Preamp screen to enter names with up to 6 characters. Touch the name to open the keypad.
Link channels for stereo You can link odd/even pairs for stereo operation. This links the preamps, processing and levels.
Use Channel Libraries to get you started open the Library to select a Channel Library and recall a typical starting point for common instruments and vocals. Set `Recall with Preamp’ on to include gain and preamp settings.
Copy / Paste / Reset Double tap a channel or master strip to copy or reset its settings. Use the popup menu.
Check Mix routing and pre/post fade settings Mixes 1-10 can be set pre or post fader, channels can be assigned, and the send point within the channel signal path can be chosen.
Touch the right arrow in the Processing screen Mix tab to view routing options. Set up a starting point for each mix with all channels on or off, and all sends pre or post.
The reset default is all pre fade, all channels assigned and the sends post-EQ (affected by the EQ but not the compressor). This is ideal for using the mixes as monitor sends.

Set up the Groups These can be configured as audio subgroups or additional stereo mixes, for example when working with many sets of in-ear monitors. Touch the right arrow in the Processing screen Grp tab to choose Mix or Group mode. If you are using subgroups to LR, remember to turn off assignments of those channels to the LR mix.
Set up the Matrix sends – Use the Processing screen Matrix Sends to work with send levels and routing.
Set up the FX Select an FX send or return and use the Processing screen to set up the 4 built-in FX units. The reset default sets up two reverbs, a delay and an ADT effect. To change these use the Library button to recall the FX type and preset. Touch the right arrow to change patching. Effects such as reverb and delay use Mix->Return patching. You can also insert FX into a channel or mix.
Set up Mute and DCA Groups Use the Processing screen Mute Grp and DCA tabs to name and assign the groups. It can be useful to assign a mute or DCA group to the FX returns providing a quick way to silence or reduce effects between songs.
Choose the Direct Output application – channel direct outputs can be used for USB recording, ME-1 personal monitoring, channel Ducker trigger or single channel FX. Set source preferences in the Processing screen Preamp page of any input channel. This setting is global and affects all direct outputs.
Patch to optional ME-1 personal monitor systems – Go to the I/O Patch Monitor screen to patch Qu outputs to the 40 ME-1 sends. It is typical to send the input channel direct outputs. The recommended direct out setting is post delay, pre fader, post mute.
Patch the USB outputs Use the I/O Patch USB Audio screen to patch any of the Qu outputs to the Qu-Drive multitrack and rear panel USB B streaming port. These share the same patch. USB B streaming uses all 32 outputs. Qu-Drive recording is fed from the first 18 outputs, and Qu-Drive stereo recording is fed from outputs 17-18.
Live show multitrack recording typically uses the channel Insert Sends so that live mixing does not affect the recording. You may wish to change this to Direct Outputs for studio recording and other applications.
Assign the SoftKeys The SoftKeys can be user-assigned for various functions such as mute, tap tempo, scenes, Qu-Drive transport and more. Assign these using the Processing screen SoftKeys strips. Confirm using the Apply button.
Footswitch You can assign control to a single or dual footswitch. Use the Setup / Control / Footswitch screen to choose the function and calibrate the operating mode of the switch.
Assign the Custom Layers Use the Setup screen Strips page to drag and drop strips to the three available custom strips.

7.3 Save the settings

Scene memories Once you have set up the mixer ready for the session, go to the Scenes screen to name and store the current mix settings as a scene. You can store up to 100 scenes within the mixer.
For example, you could name and store scenes for each band after you sound check them, as theatre show cues, recording sessions, templates for future shows and so on.
Global Scene Filter This function protects selected parameters of all channels or mix from being overwritten when any scene is recalled. For example, the SoftKey or Custom Layer assignments that you may make after sound check, or the LR mix processing including GEQ which you may change as the audience fills the room. The reset default is Custom Layer and SoftKeys blocked.
Scene Safes This function protects all parameters of a selected channel or mix from being overwritten when a scene is recalled. For example, walk-in music, DJ or presenter. The reset default is no safes set.
Per Scene Filter This is similar to the global filter but protects selected parameters for just one scene recall. Each scene has its own filter. This can be a powerful tool, for example when recalling cues in a theatre show, or effects changes during songs. The reset default is Custom Layer and SoftKeys blocked.
Show memories A Show stores everything including the current mix settings, all 100 scenes, libraries and setup. Shows are not stored within the mixer. They are created directly to a USB drive in the Qu-Drive socket.
Archiving and transferring data via USB Use a USB device such as a key or drive to archive Qu settings or transfer them between Qu mixers. The memories are compatible with all Qu models. Start by formatting the USB device on the Qu mixer. Use the Setup / Utility / Qu-Drive screen Format function.
Formatting will erase any existing data and create a Qu
directory on the device. You only need to format the USB device once on the Qu mixer. Do not attempt to edit the Qu data or file names using a computer. Keep the USB device for use with the Qu mixer only.

7.4 User permissions

You can protect the system from unauthorised access, and restrict how much control is given to certain operators. User the Home / User page. There are three User Profiles available:
Admin Has access to everything and can configure the mixer, set permissions and passwords.
Standard Can control the live mix but is locked out of system setup functions.
Basic Can control faders and mutes only.
Passwords can be set for each of the three users. These are required at each login and change of user. The Qu-Pad app requires the Admin password if set. Admin can set a separate password for Qu-You and Qu-Control apps. A scene range and login scene can be set for the Standard and Basic users.

7.5 USB recording and playback
USB B Streaming Connect an Apple® Mac or Windows® PC computer to the USB B port to stream up to 32 channels of audio in both directions and send MIDI messages.
Download the Allen & Heath DAW Control driver to convert the Qu MIDI Strip messages into HUI or Mackie Control protocol.
Download the Allen & Heath Qu Windows ASIO/WDM driver to stream Audio and MIDI to a PC.
MIDI is transmitted via the USB B port. Set the Qu MIDI channel number using the Setup / Control / MIDI screen.
Qu-Drive recording direct to USB drive You can record stereo or 18-track multitrack direct to a USB storage device plugged into the front panel Qu- Drive port.
For more information refer to the Understanding Qu-Drive and USB’ article in the Qu Knowledgebase at www.allenheath.com/support. Use the USB storage device with the Qu mixer only. Do not use it for other applications. Format the USB device on the Qu mixer before recording using the Setup / Utility / Qu-Drive screen. This clears the drive and sets up the Qu directory structure. Patch the sources to record using the I/O Patch / USB Audio screen. Choose channel sources to be from Insert Sends or Direct Out. Record Stereo or Multitrack – Use the Home / Qu-Drive screen. Recording creates WAV files in Qu directories on the USB device. Stereo recording uses the same source as multitrack CH17 and 18. Play back Stereo or Multitrack Patch USB as the source to the channels using the Processing screen Preamp source popup. SelectQu-Drive’ as the Global USB Source.
Using Qu-Drive Strips for transport control You can use Qu-Drive transport control strips for stereo or multitrack recording and playback, for example, to arm, start and stop recordings while mixing. Use the Setup screen Strips page to drag and drop strips to the three available custom strips.
7.6 A few more functions
Signal Generator The Qu mixer has a built-in signal generator. Pink noise is an excellent source for testing speakers. It generates equal energy per octave across all frequencies and can be used to check that all speaker drivers are working and to listen for phasing and polarity issues.
Channel Ducker You can insert a ducker into input channels or groups. This lets you use any signal to automatically duck (attenuate) other channels when active. For example, to use a paging mic as a trigger to duck a background music channel when in use.

Automatic Mic Mixing (AMM) This is very useful for speech applications such as conferences and seminars involving several microphones around a table. The Qu AMM can automatically take over the level of these mics to improve clarity and reduce the risk of feedback caused by many open microphones.
RTA The built-in real-time analyser provides a useful display of the frequency response of the currently selected PAFL signal. This can help in finding problem frequencies in a room or while ringing out monitors.

7.7 Network Reset

There are two reset functions available using the Qu-SB recessed panel switch above the Network socket.
While the mixer is on, use a thin pointed object to press and hold the front panel Network Reset key.
The Reset indicator will light solid GREEN and after a few seconds flash RED steadily to warn the reset is in progress. The indicator will flash GREEN rapidly to confirm the address has been reset to DHCP.

7.8 System Hard Reset Clear everything
A power-up reset is available if you need to fully reset the Qu mixer settings and its 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 (zero the board), use a Scene or the Reset Mix Settings function.
A hard reset sets all current settings to factory default and clears all
Scenes, User Libraries, User Permissions, and passwords.
First, check that all amplifiers and powered speakers are turned off.
To hard reset the Qu mixer – While the mixer is off, use a thin pointed object to press and hold the front panel Network / Factory Reset key. Plug in the Mains lead. The front panel BLUE Power indicator lights when the mixer is powered. The Reset indicator will light solid RED and after a few seconds will slowly flash RED to warn the reset is in progress.
The indicator will flash GREEN rapidly to confirm the System Hard Reset is complete.

7.9 Firmware Update Procedure
It may be necessary to update the mixer firmware using a USB device plugged into the Qu-Drive port, without an iPad connected. Use a USB device of 2GB or larger. The USB device must be formatted FAT32 file system with an Allocation unit size of 32kB. Note Formatting will delete all data on the USB device.
