Product Information:

Overview

The Dual Audio-Video Balun(MB-DAVB) allows up to two composite video signals and up to two unbalanced audio signals to be transmitted via unshielded twisted pair (UTP) cable in a point-to-point connection.Used in pairs, the Dual Audio-Video Balun, allowing audio-video equipment to be connected via space-efficient and cost-effective Cat5e/6  twisted pair cable for commercial and residential hi-definition (HDTV) video applications and so on.

 

Applications

classroom video distribution, commercial and home audio/video systems, hospital video training, video conferencing, and video kiosks

 

Features & Benefits

Video up to 2,200 feet (670m) via Cat5e/6

Audio up to 3,250 ft (1,000m) via Cat5e/6

20 Hz to 20 kHz audio bandwidth

Cost-efficient cabling

Quicker moves, adds and changes

 

Quick Setup Guide:

Plug the RCA connectors of the transmit Balun into the Video and Audio outputs of the source component you wish to transmit. Plug the Video and Audio connectors from the receive Balun into your desired input component. Insert the CAT5 cable into both ends of the Baluns. You may use standard EIA 568A/B termination.
