A&E Specifications
The mixer shall be a compact digital mixer capable of
standalone operation. It shall be capable of 64 input
channels, 42 mix busses and 400 soft patchable system
inputs and outputs, all independently assigned. There shall
be 12 stereo rack FX engines with dedicated stereo returns
and 16 DCAs. The mixer shall contain the mix engine. The
mix engine shall run at 96kHz sampling rate and employ
FPGA technology for digital signal processing. The system
latency from analogue input to output shall not exceed
0.7ms.
The surface shall include 24 motorised touch-sensitive
faders in two banks, each with 6 layers accessed by
dedicated keys. Fader illumination shall be integrated into
the armrest of the mixer and shall be adjustable via the
software user interface. All fader strips shall be configurable
as input channels, mixes, FX sends, FX returns, DCA
masters or MIDI strips. Each fader strip shall have dedicated
PAFL, Mix and Mute buttons with indicators and a rotary
controller. 6 buttons with indicators shall provide global mode
for the rotary controls being Gain, Pan, Sends and up to 3
custom functions. Send levels to mixes shall also be
adjustable via the faders.
Dedicated keys shall be provided for quick Copy/Paste/Reset
of mixes and processing parameters, pre/post and mix
assignments, scene safes, freeze-in-layers and GEQ fader
flip. Further physical controls shall be user assignable,
including two sets of 3 rotary encoders and 24 user-defined
keys.
Two 15.6” Full-HD (1080p) capacitive touchscreens shall be
provided for access to the channel bank view, channel name
blocks, channel processing, meters, FX, I/O, scene
management, setup, utilities and diagnostics. The channel
name blocks shall display each visible channel’s name,
colour, type, number, status, pan, gain, trim, metering,
processor gain reduction and other parameters. Touching a
channel name block shall select a channel, with the
capability to select one channel per touchscreen.
22-segment meters in the channel name block shall indicate
channel and mix levels. An additional onscreen 22-segment
meter shall be provided for monitoring the PAFL signal. A
default Mains to PAFL sub-mix shall be provided.
Comprehensive and customisable input, output, and FX
channel and RTA metering shall be provided on-screen in a
dedicated meters interface.
Local analogue inputs shall be provided on 12 balanced XLR
sockets and connect to fully recallable digitally controlled
preamplifiers of high quality. 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 12 balanced XLR sockets. These will have a
nominal line output of +4dBu and a maximum output of
+22dBu.
One stereo AES3 input with SRC (32-192kHz) shall be
provided on one XLR socket. Two stereo AES3 outputs with
SRC (96kHz, 48kHz, 44.1kHz) shall be provided on two XLR
sockets. There shall be an option to bypass the Sample Rate
Conversion on the digital inputs and outputs via the software
user interface.
Avantis Technical Datasheet 3 Allen & Heath Ltd
There shall be a local “SLink” Ethernet audio expansion port
with locking EtherCON connector, supporting multiple
protocols (gigaACE, DX, GX, dSnake, ME) 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.
Two 128-channel I/O ports for optional digital interface
modules shall also be provided. Optional interface modules
shall include; MADI, Dante, Waves, SoundGrid, gigaACE
and AES/EBU.
A BNC connector shall be provided on the unit for Wordclock
input or output, switchable in software.
All input channels shall contain the following processing:
Trim, Polarity, High Pass Filter, Low Pass Filter, two Insert
points, Gate, Parametric EQ, Compressor and Delay.
All output mix channels shall contain the following
processing: External input, Polarity, Trim, Insert, Parametric
EQ, and Graphic EQ with RTA and fader-flip mode,
Compressor and Delay.
The channel processing shall also include high quality
emulations of classic preamps, compressors and GEQs.
These emulations shall be insertable on the fly on any
channel without using the internal FX and without the need of
any external plug-ins. The use of any emulation shall not
result in added latency or affect processing abilities
elsewhere within the system.
All signal delays in the system shall be adjustable in
milliseconds, metres, feet and samples.
12 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. The mixing
system shall provide the options of FX racks processed
signals to be returned to other mixes via dedicated FX input
channels, with PEQ, assigned as sources to input channels,
daisy-chained to another FX rack by internal patching, or
routed to an output socket or interface channel.
There shall be 16 DCA groups, with DCA Spill functionality,
and 8 Mute groups.
The mixer shall provide Automatic Mic Mixing (AMM) of up to
64 microphone sources into 1, 2 or 4 zones. The AMM shall
be capable of running in classic gain sharing mode or
optionally as a NOM (Number of Open Microphones)
algorithm.
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 LPF, post Gate, post
Insert A return, post PEQ, post Compressor, post Insert B
return 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 input and output mix with visual
assignment status on-screen. The following types of signals
shall be available: Sine, White Noise, Pink Noise, and BandPass.
The mixer shall provide two gigabit Ethernet (1,000 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 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 500 scenes. The
scenes shall be name-able and a descriptive text entry per
scene provided. 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. A Cue List of scenes shall
be provided to facilitate a running order of scenes from the
master list. A crossfade of up to 20 seconds shall be
adjustable per scene. Scene recall may be embedded into a
scene with the option to delay the start of the embedded
scene recall by up to 4 minutes.
An option shall be provided for password protection for log-in
of several users with different levels of system access and
permissions. A specific 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, 150W
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 40 degrees Celsius.
The mixer shall be the Allen & Heath Avantis.
