A&E Specifications

The control surface shall have 20 moving faders, each with 6 layers accessed by
dedicated keys. All fader strips shall be configurable as input channels, mixes, FX
sends, FX returns, DCA masters, or MIDI strips. Each fader strip shall have a
dedicated PAFL, Mix, Select, and Mute button with indicators, 10-segment multi­point meter, 4-segment gain reduction meter, rotary encoder, and coloured LCD
display with name, mode, status, and level indicating. 7 buttons with indicators
shall provide global mode for the rotary controls being Gain, Pan, Sends and up to
4 custom functions. Send levels to mixes shall be adjustable using the faders.

A 12” capacitive touchscreen shall be provided for access to channel processing,

meters, FX, I/O, scene management, setup, utilities and diagnostics. Physical,
dedicated controls shall be provided for the 4-band PEQ. Further physical controls
shall be user assignable, including 6 rotary encoders arranged over 3 layers, and
19 user-defined keys. Dedicated keys shall be provided for quick
Copy/Paste/Reset of mixes and processing parameters, pre/post and mix
assignments, scene safes, GEQ fader flip, PAFL clear, scene automation,
talkback, and access to libraries.

22-segment meters shall indicate the 3 Main mix levels, the PAFL signal shall
override the LR meters accompanied by a PAFL-active indicator. ¼” and 3.5mm
jacks for the surface PAFL headphones output shall be provided, plus an
analogue output level control. The mixer shall include a 2-track record and
playback system for optional USB drives. The surface shall have 2 USB ports on
the front, one of which dedicated to record / playback.

The surface shall provide 6 XLR inputs of high quality and capable of handling
microphone or line signals, with remote controlled analogue gain adjustable in
1dB steps, a 20 dB PAD, and phantom power. It shall also provide 6 XLR line
outputs, 1 AES-3 stereo XLR inputs with SRC, and 1 AES-3 stereo XLR outputs

with SRC. There shall be an option to bypass the Sample Rate Conversion on the
digital inputs or outputs.

A 128-channel I/O port for an optional digital interface module shall also be
provided. Optional interface modules shall include: MADI, EtherSound, Dante,
Waves SoundGrid, and ACE.

An Ethercon port shall be provided for connection to the rack engine via the Allen
& Heath gigaACE protocol. This connection shall carry over 300x300 channels of
uncompressed audio at 96kHz, control data and tunnelling of third party Ethernet
traffic. An Ethercon port shall be provided for I/O expansion via an audio
connection carrying up to 32x32 channels of uncompressed audio at 96kHz. A
range of optional expansion racks shall be provided and shall include a modular
rack with 8-channel card options including analogue or digital I/O.

A BNC connector shall be provided on the unit for Wordclock input and output. A
pair of RJ45 sockets shall also be provided for gigabit Ethernet network
connections to laptops or other control systems.

The unit shall have a fixed power supply accepting AC mains voltages of
100~240V, 50/60 Hz, 110W max via an earthed 3-pin IEC male connector. A
rocker switch shall be provided near the mains inlet to isolate the unit from the
incoming mains supply.

An option shall be provided for password protection for log-in of several users with
different levels of system access and permissions.

The control surface shall be the Allen & Heath dLive C2500.
