Datasheet

Qu-Pac Technical Datasheet.docx 3 Allen & Heath Ltd
The mixer shall be a compact, rack-mountable digital mixing solution
without physical fader strips, but shall include 16 mono and 3 stereo
line input channels mixing to 12 mix outputs and 4 stereo rack FX
engines, 4 DCA groups and 4 Mute groups. All output mix channels
shall contain Insert, Parametric EQ, Graphic EQ, Compressor, and
Delay. Signal delays in the system shall be adjustable in
Milliseconds.
Pre/Post fader routing and assignments, processing of signals, level
sends, FX sends, DCA and Mute Groups shall be accessed and
adjusted via a 5-inch colour touchscreen provided on front panel of
the mixer or from Apple iOS touchscreen devices.
There shall be a Channel page on the touch screen replacing
physical fader strips with different tabs providing access to Input
Channels, FX, Groups, Mixes, DCA and Mute Groups and control of
level, mute, pan and PAFL for the selected channel and a fully-
customizable page giving access to channels and settings tailored to
the user and the specified application. Several ‘widgets’ shall be
assigned to this page, these shall include channel levels, mutes and
assignment on/off switches and shall be arranged to suit the user
requirement.
The front panel of the mixer shall include 16 custom select keys and
indicators, giving access to any combination of user defined input
channels, output channel mixes, FX sends, FX returns or Main mix
and also 15 assignable SoftKeys giving access to DCA mute
masters and MIDI control as well as Tap Tempo, Instant Scene
Recall/Navigation or PAFL Clear.
There shall also be dedicated keys for quick Copy/Paste/Reset of
mixes and processing parameters.
The name and number of the selected channel or mix shall always
be identified on screen when in the processing or routing pages.
The mixing system shall include application software for Apple iOS
touchscreen devices connecting via a wireless network router to an
Ethernet LAN port.
The application shall allow control of functions including the preamp
gain, phantom power, mix channel levels and shall have a graphical
representation of physical controls and indicators including signal
processing parameters and shall provide control of 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 and the application software shall
provide signal metering and processing threshold indication when
online including the Real Time Analyser.
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
monitoring 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 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 Talkback facility with the ability to send to any output mix with on
screen status indication and an option to enable talkback latching
and HPF shall be provided.
A default Mains to PAFL sub-mix and a stereo 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/ 24 bit WAV.
The mixer shall also play back stereo WAV files at 44.1 or 48 kHz
and 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.
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 wireless router (access point) for MIDI over
TCP/IP control of mixer parameters via Apple iOS touchscreen
devices for live mixing control.
There shall be a local “dSNAKE” Cat5 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 mixer shall have a built in power supply accepting AC mains
voltages of 100~240V, 50/60 Hz, 55W 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 Qu-Pac Digital Mixer.
