Audio Delay – Provides bulk (all four groups/master) and individual
card audio bus channel delay offset controls and delay parametric
displays.
Audio Delay Controls
• Bulk (Master) Audio/Video Delay Control Bulk Delay control adds bulk (all four groups) audio delay from any video
delay (net audio delay offset setting adds delay in addition to any delay
included by other actions). This control is useful for correcting lip sync
problems when video and audio paths in the chain experience differing
overall delays. (-33 to +3000 msec range in 0.01-msec steps; null =
0 msec).
Large rapid changes in bulk delay (> 500 msec) can result in
momentary full-scale noise burst on output processed audio.
This burst can damage monitors or other equipment if not
considered. Gain on output should be temporarily reduced if
performing large adjustments to delay.

• Per-Channel Audio/Video Delay Offset Controls
Offset control adds or reduces (offsets) channel audio delay from the matching video delay (audio delay offset setting adds
or removes delay in addition to any delay included by other actions). This control is useful for correcting lip sync problems
when video and audio paths in the chain experience differing overall delays.
(-800.0 to +800.0 msec range in 0.02 msec steps; null = 0.0 msec)
Delay Status shows current absolute delay from video for the corresponding audio channel.
Note: • Maximum advance/delay offset is dependent on video format.
• Where a Dolby pair is present, adjustment of either channel control results automatically in a matching delay setting
for the other channel in the pair.
