The EZ-VMD4 is a high-resolution computer video distribution amplifier with four 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 four outputs is indivually buffered for driving the computer monitor. The other three outputs are driven by separate
output amplifiers. All outputs provide flat, wideband response. All switched functions are easily accessible on the front panel.
The EZ-VMD4 is used in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms, stores
and commercial A/V systems.

SYNC INPUT SELECTOR
The SYNC switch selects between standard computer card TTL sync
and RGBHV 75 ohm video format sync. Set the switch to the NORM TTL
position (button OUT) for use with a normal computer video source; set to
the VIDEO 75 OHM position (button IN) for use with a 75 ohm sync source.
ID BIT
Set to NORM OFF position (button OUT) unless computer video
output fails to operate with the connected monitors; set switch
to ON position (button IN) if needed to activate computer video
monitor output (not typically required unless using certain laptops).
VIDEO INPUT
Connect the video source to the INPUT jack.
POWER INDICATOR

LOCAL MONITOR OUTPUT
Connect the LOCAL MONITOR
output to the input of the local
computer video monitor.
