The mixer shall be a compact digital mixer built
around a 96kHz XCVI FPGA core with 48 input
channels mixing to LR and 12 stereo mix outputs.
The surface shall include 33 moving faders with 6
layers, each layer having dedicated keys, giving easy
access to input channels, mixes, FX sends, FX returns,
DCA masters and MIDI control.
Each fader strip shall have dedicated PAFL, Select,
and Mute buttons with indicators, a variable LED
meter, a peak indicator LED and variable colour
backlit LCD display.
There shall be dedicated physical controls which allow
for adjustment of key processing parameters, and
which follow the select button for the input and output
channels.
The fader and rotary controls shall be of a high
contrast colour to the mixer surface for excellent
visibility during operation in low light conditions. The
rotary controls shall also be illuminated to indicate
function and availability for use.
Send levels to mixes shall be displayed and adjusted
using the faders.
Surface illumination shall be integrated into the
bodywork of the mixer.
Local analogue inputs shall use balanced XLR sockets
and connect to fully recallable digitally controlled
preamplifiers. These shall be able to provide up to
+60dB of gain, industry standard 48V phantom
power, and include a switchable -20dB Pad to allow a
maximum input level of +30dBu.
Local analogue outputs shall be provided on 16 XLR
sockets and 2 balanced TRS ¼ inch Jack sockets.
These will have a nominal line output of +4dBu and a
maximum output of +22dBu.
There shall be a local “SLink” Ethernet audio
expansion port with locking EtherCON connector,
supporting multiple AoIP protocols and providing
access to a maximum 128x128 digital channels,
connected over a single cable ‘digital snake’ and
allowing remote preamp control of Allen & Heath
Remote Audio Units, as well as connection to Allen &
Heath ME Personal Mixing Systems.
A digital I/O Port shall be provided to accept optional
cards, supporting a maximum 128x128 channels and
the ability to interface with 3rd party AoIP protocols
such as Dante and Waves.
All input and output processing, routing options and
system configuration shall be accessed and adjusted
via a 7-inch colour touchscreen and associated
dedicated rotary control.
16 user-assignable SoftKeys with variable colour LED
illumination shall be provided for quick access to
Input/Mix/DCA/Group Mutes, Tap Tempo, Scene
Controls, MMC and SQ-Drive Controls, as well as 8
assignable rotary encoders with LCD display showing
their current function.
A footswitch connection shall be provided to allow
assignable control from an optional single or dual
footswitch.
There shall be dedicated keys for quick
Copy/Paste/Reset of processing parameters and
mixes.
SQ-7 Technical Datasheet 2 Allen & Heath Ltd
The ability to assign channel on/off status and to
switch between Pre/Post fade to the currently selected
mix shall also be provided with dedicated keys.
All input channels shall contain the following
processing: Polarity, Trim, Insert, Gate, High Pass
Filter, Parametric EQ, Compressor, Delay, Pan.
All FX Return channels shall contain the following:
Parametric EQ, Pan.
All output mix channels shall contain the following
processing: External input, Polarity, Trim, Insert,
Parametric EQ, and Graphic EQ with RTA and faderflip mode, Compressor, Delay, Balance.
All signal delays in the system shall be adjustable in
Milliseconds.
The mixer will allow the insertion of Allen & Heath
DEEP processing models to channels, without
affecting latency or processing abilities.
8 user-assignable effect racks shall be provided with a
library of factory preset FX emulations. The FX racks
shall be individually configurable as send/return from
a channel or FX/Mix, or inserted into input or output
channels.
There shall be 8 DCA groups and 8 Mute groups.
An Automatic Mic Mixer shall be provided for
automatic and dynamic adjustment of gain in spoken
word applications.
A global source option for the direct out of each input
channel shall be provided in the routing screen. The
tap-off point shall be adjusted to the following
positions in the processing path: post Preamp, post
HPF, post Gate, post Insert return, post PEQ, post
Compressor, and post Delay. There shall be further
global options to follow Fader, DCA and Mute.
Direct outputs shall be assignable via the mixer soft
patch bay.
A Talkback facility shall be provided with the ability to
send to any output mix with on screen status
indication. An option to enable talkback latching and
HPF shall be provided.
A signal generator shall be provided with the ability to
send a variable level signal to any output mix with
visual assignment status on-screen. The following
types of signals shall be available: Sine, White Noise,
Pink Noise, and Band-Pass.
Comprehensive input, output, and FX channel and
RTA metering shall be provided on-screen.
12-LED bar meters on the surface shall indicate the
Main mix bus level and the PAFL signal shall override
the LR meters accompanied by a PAFL-active
indicator.
A default Mains to PAFL sub-mix shall be provided.
There shall be a USB Type-A connector on the surface
for stereo/multitrack recording/playback, data-transfer,
archiving, and firmware updates direct to USB drives.
On the rear panel there shall be a USB-B connection
following the USB 2.0 standard for multi-channel, bidirectional audio streaming and MIDI DAW control
between the mixer and a computer.
A DAW transport control using popular DAW control
protocols for computer shall be available via the
touch-screen.
Stereo digital output shall be provided on XLR
following the AES/EBU standard and with switchable
sample rates.
The mixer shall provide a Fast Ethernet (100 Mbit/s)
port for Cat5 cable connection to a computer for MIDI
over TCP/IP control of mixer parameters via a wireless
router (access point) for live mixing control, and the
mixing system shall include application software for
tablet and phone devices connected via a wireless
network router to the LAN port.
Input and output channel processing and parameters
in the mixer shall be saved on demand as a user
library item for recall in other channels. All library items
shall be archived with the show-file. Library items shall
be transferrable to USB drive as portable data to be
used in other systems.
The mixer shall provide the facility to save 300 scenes
of the settings of the mixing system and these scenes
shall be nameable.
A comprehensive table of ‘Scene Safes’ shall be
provided to prevent selected items from being
changed from their state when the safe was enabled.
A comprehensive scene filter shall be provided per
scene to Allow / Block each parameter saved in a
scene from being changed as that scene is recalled.
An option shall be provided for password protection
for log-in of several users with different levels of
system access and permissions. A particular scene
may be chosen to be recalled per change of userlogin if desired.
The mixing system shall periodically record all current
settings and return the mixer to that state after reboot
following a power-cycle.
The mixing control surface shall have a built in power
supply accepting AC mains voltages of 100~240V,
50/60 Hz, 110W max via an earthed 3-pin IEC male
connector mounted on the rear chassis. A Two Pole
Push-Button switch shall be provided near the mains
input.
Recommended operating temperature for the mixer
shall be 5 to 35 degrees Celsius.
The mixer shall be the Allen & Heath SQ-7.
