AES AUDIO CONNECTIONS (MODEL 7707VAT)
AES AUDIO IN:
Balanced or unbalanced AES audio inputs for channel 1&2 (AES 1) and 3&4 (AES
2) of an audio group. Each input (+, -, GND) is on three of six pins on six pin
terminal header. AES inputs can be synchronous or asynchronous to each other
and/or input SDI video.
For Balanced AES signals connect the + and – signals to the respective input pins.
The AES TERM Jumpers J26 and J27 must be set to the
110
position for proper
termination of the balanced AES inputs. The AES LEVEL jumpers J24 and J25 are
normally set to the HI position for balanced AES signal levels of 2 to 7 volts. For
signal levels below 2 volts, move the AES LEVEL jumpers to the
LO
position. (See
Unbalanced AES signals should be connected to the AES+ input pins with the
ground connected to the AES- input pin. The AES TERM Jumpers J26 and J27
must be set to the
75
position for proper termination of the unbalanced AES inputs.
The AES LEVEL jumpers J24 and J25 do not have any effect when the TERM
jumpers are in the
75
position. (See section 7.4 and 7.5)

AES AUDIO CONNECTIONS (MODEL 7707VAT-U)
AES AUDIO IN:
Unbalanced AES audio inputs for channel 1&2 (AES 1) and 3&4 (AES 2) of an
audio group are available on two BNC connectors. AES inputs can be synchronous
or asynchronous to each other and/or input SDI video. The AES inputs on the card
should be configured at the factory for use with unbalanced oututs. (See section
7.4)
2.4.
ANALOG AUDIO CONNECTIONS (MODEL 7707VAT-A4)
ANALOG AUDIO IN:
Balanced analog audio inputs for 4 channels. Each input (+, -, GND) is on three of
twelve pins on twelve pin terminal header.

OPTICAL SIGNAL CONNECTIONS
OPTICAL OUTPUT:
Output SC/PC, SC/PC with cover (shown), ST/PC or FC/PC female connector. This
output contains the input SDI video signal combined with the AES audio present at
the AES1 and AES2 inputs. Any ancillary data (e.g. embedded audio, closed
captioning, etc) present in the input SDI video stream prior to multiplexing, is
transparently passed through to the output. This optical output is available in
1310nm, 1550nm, up to sixteen CWDM wavelengths (ITU-T G.694.2 compliant) and
up to 40 DWDM wavelengths in the 1530nm to 1560nm range.(ITU-T G.694.1
compliant). The output wavelength is marked on the rear panel of each module.
When connected directly to a companion module, the output is compatible with
multi-mode fiber optic cable. If not connected directly (i.e. connected through
CWDM, DWDM, WDM, or splitter/combiner) the output is compatible only with
single-mode fiber optic cable.
