Compatibility Charts
Under certain circumstances, the audio and video may be acceptably peaked
even though the audio and video path lengths are different. Because the audio
signal is digital, and more forgiving than the video signal, it may be possible to
peak the video and have functioning audio. It is difficult to predict outcomes
because it is dependent on the difference in cable lengths, the video rates, and
acceptable video quality.
The following Auto Compensation and Audio Breakaway compatibility charts
are arranged with transmitters listed on the left and receivers listed across the
top. The QM cable exits the transmitter and the QM cable enters the receiver.
NOTE: The cable exiting the QM-AE is a loop-through and is not listed as a
transmitter.
NOTE: QM wallplates and fliptop boxes are not included because the audio and
video cable lengths are always equal.
KEY: 9 = Good operation.
1. = Operation depends on video rates and if the audio and video cable lengths are closely matched.
2. = In these cases, if the audio and video (although from different sources), switch together consistently,
the system will operate normally. If the audio and video switch inconsistently, operation then
depends on the video rates and how closely the audio and video cable lengths match.
* = Device with self-peaking.
