OPERATING THE M80
DSP Options
When audio and video signals are input to the M80 they each
get processed in dierent sections of the M80 by dierent
processors. The amount of time it takes to process the audio
and video signals isn’t always the same. Additionally, the video
signal typically goes through some additional processing at
the Video Display. This can cause the audio and video to be out
of sync.
Lip Sync Delay
The Lip Sync setting compensates for the dierence
between the time the video image is displayed and the
audio outputs from the speakers. Since the video typically
trails the audio, Lip Sync allows up to a 120ms (0.12 sec-
onds) delay on the audio output to the speakers. Lip Sync
delays all speakers an equal amount so the delay (dis-
tance) settings congured in SmartEQ are not changed.
