The EZ-VMD4 is a high-resolution computer video distribution amplifier with four outputs. The input has an associated BIT ID switch to assure compatibility with various computers. Sync is front-panel switch-selectable between standard TTL or video. One of the four outputs is individually buffered for driving the computer monitor. The other three outputs are driven by separate output amplifiers that provide flat, wideband response. All switched functions are easily accessible on the front panel.  MADE IN USA.
