Compact CAT5 Audio/Video Splitter

3. Operation
The video signal is fully terminated and buffered for the local video
output connector. This means that terminating or plugging a local
monitor is not necessary and this connector can be left open.
The stereo audio input is passed through to the local audio output
connector and the audio integrity is fully preserved. The transmitted
audio in the CAT5 cable to the remote receiver is monaural. The audio
outputs are “line-level” and powered speakers are required.
Assuming that there are no major grounding or large EMI noise
problems present, the video quality at the remote station depends on the
length of the CAT5 cable, actual video resolution and refresh rate.
The Model AC155A receiver employs proprietary user settable video
compensation to enhance the image quality when long cables are used.
In general at low and mid resolutions excellent image reproduction is
provided at up to 500 feet. At high resolution and refresh rates perfect
image reproduction can be achieved at shorter distances (see table 3.1
below). Using longer cables or higher resolution rates will still produce
an image, but the reproduction quality will be reduced.
