M-DAVB
Introduction
The Dual Audio-Video Balun(M-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.
Features
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
