VGA/XGA switcher/equalized amplifier
The EZ-VM22E is a high-resolution computer video source selector and distribution amplifier with two inputs and two outputs. A front-panel switch selects between the inputs. Each input has an associated BIT ID switch to assure compatibility with various computers. The sync for input one is front-panel switch-selectable between standard TTL or video. One of the two outputs is individually buffered for driving the computer monitor. The second output is driven by separate output amplifiers that include rear-panel gain and equalization trimmers that provide adjustable compensation for quality monitor cable lengths exceeding 300′. All switched functions are easily accessible on the front panel. Input switching is fully solid state for long-term reliable immunity from switch noise and the bandwidth limitations of mechanical switches.
