K-707/8 Twisted Pair CV/Audio Tx/Rx

 
 

K-707 and K-708 Twisted Pair Transmission System consists of the K-707 high performance Composite Video/Mono Audio to Twisted Pair Transmitter and the K-708 companion Receiving Unit, which converts the Twisted Pair format back to Composite Video and Mono Audio. Transmission via twisted pair cable carries video signals farther than conventional coax cable, and is lighter and significantly less expensive. A simple system consists of a K-707 located at the source, and a K-708 located at the remote display device. For systems with multiple monitors, the K-708 Receiver has a Loop/Termination switch allowing several K-708 Receivers to be placed on the same Twisted Pair cable driven by a single K-707 . Even at a cable length of 400 meters, the frequency response is well over 6 MHz, and at shorter distances they provide close to broadcast level performance. Recessed gain and equalization controls are provided to optimize signal levels. A 12V power supply is provided with each unit. The K-707 and K-708 are part of the Kramer Tools family of compact, high quality, and cost effective solutions for a variety of applications
