EZ-VMD2
VGA/XGA Distribution Amplifier
TYPICAL APPLICATION
The EZ-VMD2 is a high-resolution computer video distribution amplifier with two outputs. The input has an associated ID BIT
switch to assure compatibility with various computers. Sync is front-panel switch-selectable between standard TTL or 75 Ω
video. One of the two outputs is indivually buffered for driving the computer monitor. The second output is driven by separate
output amplifiers. Both outputs provide flat, wideband response. All switched functions are easily accessible on the front panel.
The EZ-VMD2 is used in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms, stores
and commercial A/V systems.
