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.
