MDA 3AV	1x3 Composite with Stereo Audio	60-439-20	Retired

This product has been retired.

The Extron MDA 3AV is a compact, one input, three output composite video with stereo audio distribution amplifier. It accepts composite video on one female BNC connector and balanced/unbalanced audio on captive screw connectors, and outputs the amplified signal on three female BNC connectors and captive screw connectors up to 150 feet (45 meters).

The MDA 3AV is rack or under-desk mountable and comes with an external international power supply. Its small size makes it the ideal solution for easy integration into both new and existing AV systems including boardrooms, training facilities, home theater, command and control centers, and rental and staging environments.
