The EZ-VMD4E 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 two outputs is indivually buffered for driving the computer monitor. The other three outputs are driven by separate output amplifiers that include rear-panel gain and equalization trimmers that provide adjustable compensation for quality monitor cable lengths exceeding 100 m (300 ft). All switched functions are easily accessible on the front panel.
