8916 AES/EBU Auto-Tracking
Delay DA
Introduction
The 8916 Auto-Tracking DA is a 1 x 7 distribution amplifier for AES/EBU
serial digital audio. It delays digital audio to correct lip-sync errors. The
8916 offers two forms of delay, which are summed:
■ A fixed delay up to 0.5 seconds
■ A variable delay based on the signal input from a Grass Valley video
frame synchronizer
The 8916 can correct a large, fixed lip-sync error while continuously
adjusting audio delay to match video delay created by a frame sync’s asyn-
chronous video input.
The 8916 offers the following features:
■ Up to 0.5 second delay in 2 ms increments
■ Auto-tracks Grass Valley video frame sync delays (models 8900FSS,
SMS 8121-FS, 8981FS, VFS211, and 8960DEC)
Note Early versions of the 8960DEC did not support the export of the auto-track
signal. Contact Grass Valley customer service for more information regarding
8960DEC frame sync.
