7.3 Getting to Know the 707/708 Video/Audio Line Transmitter/Receiver
The KRAMER
707 Video/Audio Line Transmitter and the 708 Video/Audio Line Receiver, of the KRAMER
TOOLS family, are used as a pair for transmitting video and mono audio over long distances using twisted-pair
wire. A termination switch allows several
708 receivers to be looped-through on the same line (one transmitter -
multiple receivers). This pair of machines is best at distances of up to 200 meters. At shorter distances, they
provide close to broadcast level performance. They also provide user controlled Gain and HF compensation.
NOTE
For Installation, operation, maintenance and troubleshooting instructions please refer to sections 8-13.
