Audio & Video 4 RCA , 4xRCA to 1xRJ45

4xRCA to 1xRJ45

The Lemar Dual Audio-Video Balun uses four pairs unshielded twisted cable to transmit two baseband video signals and two baseband audio signals. When used in pairs the Lemar Dual Audio-Video Balun offers the end-user a speedy and money saving way to connect AV equipment using twisted pair rather than coax cabling.

Use of the Lemar Dual Audio-Video Balun together with the Lemar CCTV-Audio/Video Hub allows signal distribution to multiple monitors.

It is ideal for end users in the video communications and distributions industries and applications such as professional video training and video conferencing for businesses and classrooms, public presentation support, public information kiosks and audio/video systems for home and office.
