8921ADT Instruction Manual 13
Installation
To use J11 and J12 as unbalanced audio outputs if a tracking input or output
is not required, jumper J5 to pins 1-2 (AES1) and J6 to pins 1-2 (AES2). Refer
to
Figure 1 on page 9 and Tracking Input/Output on page 13 .
Figure 4. 8921ADT Rear Input/Output Connectors
Tracking Input/Output
A Tracking Input is provided at BNC J11. Connect an RS-232 level auto
tracking signal from a video frame synchronizer (such as an 8900FSS or
8981FS) to this BNC and set jumper J5 (
Figure 1 on page 9 ) to TRK IN
(pins 2-3).
If you need to loop the tracking input signal to another destination, a buff-
ered looping output is available at BNC J12. To make this Tracking Output
available, jumper J6 (
Figure 1 on page 9 ) to pins 2-3 (TRK OUT).
If no input and/or output audio tracking is needed, these BNCs can be
jumpered to provide additional unbalanced AES 1 and AES 2 BNC outputs
as described in
Digital AES Audio Outputs on page 12 .
Reference Loop-through Input
Connect an NTSC/PAL analog color black reference, AES 48 kHz Word
Clock signal, or 48 KHz AES3-id DARS signal to one of the loop-through
reference connectors, J13 or J14. Terminate the unused connector into 75
Ω
if the signal is not looped to other equipment.
