새 페이지 1 The Extron MDA 3V is a one input, three output composite video Mini Distribution Amplifier. It accepts composite video on one female BNC connector and outputs the amplified signal on three female BNC connectors up to 150 feet/45 meters.

Part of the VersaTools? line of economical, compact products, the MDA 3V 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 A/V systems including boardrooms, training facilities, home theater, command and control centers, and rental and staging environments
