Essential Info

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 ID BIT switch to assure compatibility with various computers. The sync for input 1 is front-panel switch-selectable between standard TTL or 75 Ohm video. One of the two outputs is indivually 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 100 m (300 feet). 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. The EZ-VM22E is used in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms, stores and commercial A/V systems.
