Ensemble Designs 6040 Tracking Audio Delay - Manual (Page 5)

Tracking an All Digital Path
The application below shows how the 6040 can be used in a digital path. Here, the 6040 is
used in conjunction with a Model 5450 Digital Video Frame Synchronizer. Both the 5450
and the 6040 can be used for monitoring.
Delaying Compressed Audio (non-audio) Sources
Another application for the 6040 is delaying compressed audio streams such as AC-3 or
Dolby E. In the illustration shown below, the 6040 locks to the incoming data stream (48
kHz only), delays the data using only the bulk delay value (tracking delay is set to 0), and
mutes the analog outputs. If the non-audio data is not at a 48 kHz sample rate, all of the
outputs will be muted. Note that the 6040 will automatically enter into this mode when it
detects a non-audio source on the Digital input.
