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
