Audio Control
There are two forms of the lip sync delay commands, the ‘LSZ’ command which sets lip sync delay on
a zone by zone basis, and the ‘LSI’ command which sets delays on a input by input basis. Which one to
use depends on what is causing the video delay, and where it’s connected in the video path.
If the input of a video processor (or monitor) that adds a video delay is connected to a zone, then the
‘LSZ’ command should be used to delay the audio by the same amount of time the video is being
delayed. Only audio that is being sent to the video processor, attached to the zone, will be delayed.
If on the other hand, if the output of a video processor that adds a video delay, is connected to an input,
then the ‘LSI’ command should be used. This allows all zones that connect to the video processor, to
have their delays automatically adjusted to compensate for the processor’s video delays.
Both inputs and zones can have delays set, however the overall delay cannot exceed 8191 counts (or
170.65mS). If an input and zone combination exceeds 8191 counts, no error will be generated and the
delay will be set to 8191.
For examples, see the examples of the ‘LSZ’ command on page 26.
