The Extron MDA 3AV RCA, MDA 5AV RCA, and MDA 5SVA RCA Mini

Distribution Amplifiers (MDAs) are compact distribution amplifiers for the distribution of a single source input to multiple outputs and are ideal for a wide range of A/V applications including boardrooms, training facilities, home theater, command and control centers, and rental and staging. The MDA 3AV RCA offers one input, three output composite video and unbalanced stereo audio on RCA connectors. The MDA 5AV RCA offers one input, five output composite video on BNC connectors and unbalanced stereo audio on RCA connectors. The MDA 5SVA RCA offers 1x5 S-video on 4-pin mini-DIN and unbalanced stereo audio on RCA connectors. The input on all three models feature a separate, passive loop-through channel that can be used to chain together several MDAs to provide additional outputs. MDAs are housed in half rack width, 1U metal enclosures and include an internal power supply that will accept 100-240VAC.
