Connecting the AES Reference Signal
The AES Reference input BNC connectors are located on the right hand side of the Utah-400
midplane (facing the backplane).
These BNC signal connections are looped-thru and must be terminated with a 75 Ohm, 1%
BNC Terminator, if not daisy chained to another reference input.
The Reference signal is required so the Utah-400 Digital Audio Router can switch on the
frame boundary . Using the Sync signal avoids the possibility of clicks in the digital audio while
switching.
The following signal is acceptable to used as the Utah-400 AES Reference:
•
AES Sync must be AES-3.
