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.
