Audio Inputs
The number and configuration of the audio inputs depends on the specific model of ABT
you are using.
Reference Input (Looped Through)
An external reference signal is required to synchronize the SDTI outputs. An analog video
reference signal, word clock or AES-75 signal can be connected to one of the REFERENCE
SIGNAL connectors. If the loop-through is not used, a 75
termination on the other
REFERENCE SIGNAL connector must be used to properly terminate the line.
For an Audio Bridge Terminal with an AES breakout panel, AES INPUT 1 can also be used for
synchronization. This input signal must be error-free PCM audio sampled at 48 kHz. In the
case where both REFERENCE SIGNAL and AES INPUT 1 have valid references, the signal
connected to REFERENCE SIGNAL has priority.
