Kramer Electronics TP-1xl Getting to Know the 705/704 Video Line Transmitter/Receiver, HF trimmer

7.2Getting to Know the 705/704 Video Line Transmitter/Receiver

The KRAMER 705 Video Line Transmitter and the 704 Video Line Receiver, part of the KRAMER TOOLS family, are used as a pair for transmitting video over long distances using a twisted-pair wire. A termination switch allows several 704 receivers to be looped-through on the same line (one transmitter-multiple receivers.) The frequency response of the pair is well over 6.7MHz, even at 400m. At shorter distances, they provide close to broadcast level performance. The machines offer user controlled Gain and HF compensation.

NOTE

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