A&E Specifications
Qu-32 Architects and Engineers Specification
The mixer shall be a desktop digital mixer with 32 mono and
3 stereo input channels mixing to 24 mix outputs.
There shall be 4 stereo rack FX engines, 4 DCA groups and
4 Mute groups.
The surface shall include 33 moving faders with 3 layers,
each layer having dedicated keys and indicators, giving
access to input channels, output channel mixes, FX sends,
FX returns, Main mix, DCA masters, and a customisable
layer giving access to MIDI control as well as user-defined
overview of channels.
Each fader strip shall have a dedicated PAFL, Mix, Select,
and Mute button with indicators, a 3-LED multi-point meter,
and coloured LED indicating fader assignment.
Ability to assign channel on/off status to the current mix
using the channel ‘Mix’ keys shall be provided.
All processing, Pre/Post fade routing and assignments of
signals to mix send, FX send and Audio, DCA and Mute
Groups shall be accessed and adjusted via a 7-inch colour
touchscreen provided on the mixing surface.
The name and number of the current selected channel or mix
shall be identified on screen when in the processing or
routing pages.
Qu-32 Technical Datasheet 3 Allen & Heath Ltd
Send levels to mixes shall be displayed and adjusted using
the faders.
All output mix channels shall contain the following
processing: External input, Trim, Polarity, Insert, Parametric
EQ, and Graphic EQ with RTA and fader-flip mode,
Compressor, Delay.
All signal delays in the system shall be adjustable in
Milliseconds.
10 user-assignable soft keys shall be provided for quick
access to Mute Groups, DCA Mutes, Tap Tempo and Scene
Recall. There shall also be dedicated keys for quick
Copy/Paste/Reset of mixes and processing parameters.
A Channel Ducker shall be provided to reduce the level of
selected channels when a designated channel is in use. This
channel priority shall be available across all mono and stereo
input channels and also channel groups.
4 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.
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 for Follow Fader, and
Follow Mute.
Direct outputs shall be assignable via the mixer soft patch
bay to any physical output socket interface channel or ME
channel.
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.
A default Mains to PAFL sub-mix shall be provided.
12-LED bar meters on the surface shall indicate the 3 Main
mix buss levels, the PAFL signal shall override the LR
meters accompanied by a PAFL-active indicator.
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 quarter-inch jack socket for PAFL headphones output shall
be provided, with an analogue output level control.
The mixer shall include stereo and 18-track
recording/playback to optional USB hard drives. The format
shall be 48 kHz/ 16 bit WAV.
The mixer shall play back stereo WAV files at 44.1 or 48 kHz
and shall have a USB Type-A connector on the surface for
recording, playback, data-transfer, archiving, and firmware
updates to USB drive.
On the rear panel there shall be a Type-B USB connection
following the high-speed USB 2.0 standard for multi-channel,
bi-directional audio streaming of 32 out / 32 in 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.
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.
The mixing system shall include application software for
Apple iOS touchscreen devices connected via a wireless
network router to the LAN port and allow control of functions
including the preamp gain, pad, and phantom power.
The application shall have a graphical representation of
physical controls and indicators present on the surface
including signal processing parameters and shall provide
control of output channel processing including Parametric
EQ, Graphic Eq, Compressor and Delay. Routing
assignments and level adjustments of input signals to all
mixes and bus shall be provided. The application software
shall provide signal metering and processing threshold
indication when online including the Real Time Analyser.
There shall be a local “dSNAKE” Ethernet audio expansion
port with locking Ethercon connector, providing up to 38 input
signals and 20 output signals, plus 40 personal mixing sends
to be connected over a single cable ‘digital snake’ and
allowing Remote Preamp control to an Allen & Heath
AudioRack, or Allen & Heath ME Personal Mixing Systems.
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. Individual processing sections shall
be save-able on demand as user library items for that type.
All library items shall be stored on board and 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 100 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 user-login 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, 95W
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.
The mixer shall have an optimised fan-less airflow design for
silent operation.
Recommended operating temperature for the mixer shall be 5
to 35 degrees Celsius.
The mixer shall be the Allen&Heath Qu-32 Digital Mixer.
