The Extron MDA 4V SDI Mini Distribution Amplifier is part of the VersaTools® 
line of economical, compact products that feature a quarter rack width 
enclosure. The MDA 4V SDI is a four output distribution amplifier that accepts 
SMPTE-259M Serial Digital Video on a female BNC connector and amplifies the 
buffered and re-clocked output. It will automatically recognize PAL, NTSC, 
component 4:2:2, and widescreen 4:2:2 digital video standards. Automatic cable 
equalization typically equalizes greater than 1,000 feet (300 meters) at 270 
Mbps through Extron RG6 or equivalent high quality cable.
The MDA 4V SDI is rack or under-desk mountable and comes with an external 
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.
