3. Introduction to Qu-SB Qu-SB is part of the Allen & Heath Qu Series of digital mixers. It is similar to the faderless Qu-Pac but without front panel controls. Qu-SB provides a compact solution for wireless mixing using an iPad. An external WiFi router (wireless access point) is required.
The following diagram shows the available Qu-SB signal flow and processing. A more detailed diagram and further information is available within the Qu Mixer Reference Guide which can be downloaded from the Allen & Heath website.
4. Installing Qu-SB 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. Rubber feet 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.
5. Connector Panel This is the front panel of the mixer. It provides all control and audio connections, USB sockets, headphones and reset functions. The only connection provided on the rear panel is the mains power input. 4 5 8 9 10 6 7 1 2 3 15 11 12 13 14 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.
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.
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.
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.
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.
6.6 Get to know the Qu-Pad app 1 2 3 7 5 6 8 4 1 Logout button – To disconnect and close the app, simply double click the iPad Home button and swipe the app off the screen.

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.
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.
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.
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.
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.
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.
