A&E Specifications
The expander shall be rack-mountable and shall include plastic
feet for shelf or floor operation. It shall provide 4 slots to fit any
combination of analogue or digital 8-channel I/O modules.
A pair of Ethercon ports shall be provided for redundant
connection to a dLive S Class control surface or mix engine
over Fast Ethernet. Connection to dLive C Class, Avantis, SQ
and AHM-64 systems shall be via a single cable connection.
This connection shall carry up to 32x32 channels of
uncompressed audio at 96kHz and control data. It shall also
provide automatic firmware update to the expander at power up
of the system when a firmware mismatch is detected.
Available I/O modules shall include:
• 8 recallable preamps with XLR connectors for
balanced or unbalanced microphone and line level
signals. Gain, Pad and 48V shall be digitally controlled
within the preamp. A phantom power indicator shall be
provided. Standard and premium (PRIME) versions of
this module shall be available.
• 8 line level, balanced XLR outputs. The outputs shall
be relay protected to prevent power on or off thumps.
Standard and premium (PRIME) versions of this
module shall be available.
• 4x stereo AES3 inputs on XLR with SRC (32kHz –
192kHz sampling rate). It shall be possible to bypass
Sample Rate Conversion for each socket.
• 4x stereo AES3 outputs on XLR (44.1kHz, 48kHz or
96kHz switchable).
The unit shall have a modular power supply accepting AC
mains voltages of 100~240V, 50/60 Hz, 300W max via an
earthed 3-pin IEC male connector. A rocker switch shall be
provided near the mains inlet to isolate the mixer from the
incoming mains supply. The unit shall also provide the option
for a second, hot-swappable, redundant power supply. This
shall be of the same type and interchangeable with the power
supply fitted as standard.
The expander shall be the Allen&Heath dLive DX32.
