1. Important Information
Safety
Before powering on the SQ, read the safety instructions sheet
(AP9240/CL1-1) supplied with the unit. For your own safety and that of the
operator, technical crew and performers, follow all instructions and heed all
warnings included in these documents and printed directly on the equipment.
Ventilation
Do not obstruct the sides of the SQ, or any of the air vents when in use.
Adequate ventilation is required for the cooling fans especially.
Support
For further support with SQ, please visit support.allen-heath.com, or contact
your local distributor.
Registration
To be kept informed of updates, the latest firmware and new releases for the
SQ range, register your SQ at www.allen-heath.com/registersq
Firmware updates and apps
Visit www.allen-heath.com to obtain the latest version of firmware, release
notes and reference guide.
Firmware releases contain important updates and performance
enhancements and are also required for access to the latest DEEP
Processing units.
The firmware on the SQ and all app versions must have the same major
release number. This is the first two digits of each release number.
i.e. 1.5.3 and 1.5.5 = compatible
1.5.3 and 1.4.3 = not compatible

Reference Guide V1.5.0
2. Introduction
Welcome to the SQ Reference Guide.
Designed for applications where high-quality audio mixing and processing is
required in a compact and reliable unit, and built on an Allen & Heath XCVI
core, the SQ series of digital mixers feature 96kHz variable bit-depth
processing and ultra-low latency.
All SQ models can be used standalone or expanded with a range of remote
audio units and option cards. They can also be customised with additional
processing options.
Having the same processing core means all models have the same mixing
capabilities, and so this guide is generalised. Where necessary, it will be noted
which model is being discussed. The differences are as follows:

4. Operational Overview
4.1 Physical Control of the SQ
Keys –All keys are labelled, and most illuminate to show when they are active. All
perform specific functions, aside from the ‘SoftKeys’which are user assignable.
Faders –There are 6 layers of assignable fader strips. For all inputs and FX returns
the fader controls the send level of this channel to the selected mix. FX Send, Mix
(Aux/Group) and Matrix faders control master levels. DCA faders control the level of
the DCA groups, and MIDI faders send MIDI level messages. All fader strips are also
used by the GEQ ‘Fader Flip’ function.
Rotary Encoders (Rotaries) –These illuminate when active and are used to adjust
various parameters. Most are dedicated to parameters for the currently selected
channel or mix, though one is for use with the touchscreen. The SQ-6 and SQ-7
feature additional ‘Soft Rotaries’ which are user assignable.
Touchscreen –The touchscreen allows simple user interaction through on-screen
buttons and menus. Parameters can also be selected on-screen and adjusted using
the touchscreen rotary. When a parameter is selected, it will turn yellow on the screen,
and the touchscreen rotary will illuminate to indicate it can be used.

Reference Guide V1.5.0
6. I/O Patching
There are two ways to patch input sockets to input processing channels, either in the
Preamp section of the channel processing screen, or in the I/O screen. For patching
multiple input channels, it is easiest to use the I/O patching screen, which is also used
for all output patching.
Press the ‘I/O’screen key to display the patching matrix.
6.1 Patching Sources and Destinations
•Touch one of the tabs on the far left then select one of the following:
‘Inputs’> ‘Input Channel’ = to input channels of the SQ for mixing.
‘Inputs’ > ‘Mix Ext In’= directly to mix (without processing or level control).
‘Outputs’ > ‘Direct Outs’= from the direct outputs of input channels.
‘Outputs’ > ‘Mix Outs’= from all mix outputs (LR, Aux, Group, Matrix).
‘Outputs’ > ‘Rack FX’= from FX return channels.
‘Outputs’ > ‘Listen Out’ = from PAFL, talkback and Listen outputs.
‘Tie Lines’ = to and from all possible sources and destinations.
•When patching inputs, the input sockets are displayed at the top of the matrix and
the destination channel (in the SQ) is displayed to the left.
•When patching outputs, the source (from the SQ) is displayed at the left of the
matrix, and the output sockets are displayed at the top.
•When patching Tie Lines, input sources are shown on the left and output
destinations are shown at the top.
•Touch and drag the grid on-screen to see more input and output channels.
•Touch the ‘SLink‘ or ‘I/O Port‘ tab multiple times to display channels 1-32, 33-64,
65-96 or 97-128. There are four marks on each tab to show which screen is
currently displayed.

19
Reference Guide V1.5.0
Patching a Source to a Destination –
•Touch the ‘Patch’ button on the screen at the top left of the patching matrix to
enable patching.
•Touch a patching block on the matrix to make or delete a patch.
•Available patching blocks are grey and are filled light grey when patched.
•Currently unavailable patching blocks are dark grey and striped light grey when
patched.
•Input or Output sockets that are currently in use are dark grey (including if they
are being used by insert points). Sockets that are not in use are light grey.
The Patch switch will be turned off automatically whenever leaving the I/O screen. It can
be disabled entirely in the Surface Prefs screen.
All patching to a currently disconnected device will become active once the device is
connected.
Sequential Patching –
For quick sequential patching (also known as ‘block’, ‘one-to-one’or ‘diagonal
patching’)
•Touch and hold the first available patching block you wish to patch to until the
touchscreen rotary illuminates.
•Turn the touchscreen rotary increase or decrease the number of channels you
wish to patch; these are displayed as blue patching blocks.
•Remove finger from screen to apply patching.
It is not possible to delete patches sequentially, so the starting patching block must be
currently unpatched.
patched but currently unavailable

20
Reference Guide V1.5.0
Input Channel Patch Libraries –
Pressing the ‘Library’ key on the surface when the ‘Input Channel’ tab under ‘Inputs’ is
active will display the IP Channel Patch Libraries.
These can be used to store and recall input channel patching for different setups and
provide a quick method of switching the entire input patch for virtual soundcheck.
For quick setup, factory presets for one-to-one patching from each input type are
provided.
Input libraries store and recall all input patching, not just the currently selected source.
6.2 Local Sockets
The local input and output options in the I/O screen match the analogue input and
output socket labels on the SQ.
6.3 SLink Sockets
The SLink port is compatible with dSnake, DX and gigaACE/GX. It switches between
these modes, so multiple protocols over a single connection are not supported.
The current mode is shown on the tab in blue text unless nothing is connected, in
which case ‘Not Connected’ is displayed.
Check www.allen-heath.com for the full list of supported configurations.
Touch the tab multiple times to display channels 1-32, 33-64, 65-96 or 97-128. There
are four marks on each tab to show which screen is currently displayed.
6.4 ME Systems
ME-U, ME-1 and ME-500 units use the dSnake protocol, so can either be connected
directly, or connected to the monitor or expander ports of an AR2412 or AB168.
The ME patching is applied to any SLink port that is running the dSnake protocol,
which could be the SLink port, an SLink option card, or both at the same time. The
‘SLink’ and/or ‘I/O Port’ text on the ‘ME’ tab are displayed in white when patching is
active on either port.
ME-U and ME-1 units can accept 40 total channels, ME-500 units accept 16 mono or
stereo channels.
Stereo channels are set on the SQ in Mixer Config settings and should be patched to
odd/even channel pairs when using ME-500 units.
ME-500 units automatically assign the first 16 stereo or mono sources they receive to the
16 available keys.
