6.8 Getting to Know the TP-12xl Video/Audio Twisted-Pair Line Receiver

The KRAMER
TP-12xl
Video/Audio Line Receiver, which is based on the latest technology, works in conjunction with the
TP-11xl
Video/Audio Line Transmitter. The
TP-12xl
allows parallel connection of several units on the same line (one transmitter/multiple receivers) that can be tapped at any point without affecting image quality. When connecting several units, all the termination switches on the rear panel of the
TP-12xl
machines, except for the last on the line, should be toggled to the Hi-Z position. The frequency response of the
TP-12xl
matches that of the
TP-11xl
transmitter, and it provides polarity switching on the rear panel.

NOTE

For Installation, operation, maintenance and troubleshooting instructions please refer to sections 8-13.
