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 an outcome 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 wall plates and fliptop boxes are not included because the audio and

video cable lengths are always equal.

KEY:  = 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.
