Video Reference
AirCleaner
®
accepts either Bi-Level or Tri-Level analog
reference. SD video signals can only be locked to a
Bi-Level external reference signal (or to the video input
or free run). HD video signals can be locked to either
Tri-Level or Bi-Level reference, as long as the frame rate
of the video and the reference signal are matched.
The reference signal will lock both the PGM OUT and
TAP OUT together in time with the reference signal. The
reference input is internally terminated (no loop-thru).
Reference can also be set to lock to the PGM IN or AUX
IN video signal or set to free run.
The input video format must be at the same frame-rate
as the input reference signal.
To Set the Video Reference Type
All audio/video outputs from the system will be locked
