Audio Connections
On X75HD/X75SD systems equipped with an HDTV audio option, up
to eight stereo channels can be processed from any of the following
inputs:
• 4 analog mono channels
• 2 or 5 x AES
• SDTV embedded (four groups, eight mono channels)
• HDTV embedded (four groups, sixteen mono channels)
DARS Inputs
The DARS input is available on the standard X75OPTCAB-8-C coax
cable, optional X75OPTCAB-8-X XLR cable, or optional
X75OPTCAB-8-CX combination BNC/XLR breakout cable.
The DARS Bal/UnBal Sel parameter selects between the unbalanced
(coax) and balanced (XLR) type of connection. Primarily, the DARS
(Digital Audio Reference Signal) is used for the audio synchronization.
AES/EBU Inputs
The AES1 and AES2 inputs are available on the standard
X75OPTCAB-8-C coax, optional X75OPTCAB-8-X XLR cable, or
optional X75OPTCAB-8-CX combination BNC/XLR breakout cable.
The AES3, AES4 and AES5 inputs are available only on the standard
X75OPTCAB-16-C coax, optional X75OPTCAB-16-X XLR cable, or
optional X75OPTCAB-16-CX combination BNC/XLR breakout cable.
The AES# Bal/UnBal Sel parameters select between the unbalanced
(coax) and balanced (XLR) type of connection. Only one input
connection type is supported.
AES/EBU Outputs
The AES1 and AES2 outputs are available on the standard
X75OPTCAB-8-C coax, optional X75OPTCAB-8-X XLR cable, or
optional X75OPTCAB-8-CX combination BNC/XLR breakout cable.
The AES3, AES4 and AES5 outputs are available only on the standard
X75OPTCAB-16-C coax, optional X75OPTCAB-16-X XLR cable, or
optional X75OPTCAB-16-CX combination BNC/XLR breakout cable.
Both the unbalanced (coax) and balanced (XLR) AES audio signals are
present at all time on both D-Sub connectors.
