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 Ω 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 ft). 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.

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 BITS (separate switch provided for each input)
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 1
Connect the primary video source to INPUT 1.
VIDEO INPUT 2
Connect the secondary video
source to INPUT 2.
INPUT SELECTOR
Select INPUT 1 (button IN) or
INPUT 2 (button OUT) to feed
the rear-panel OUTPUT jacks.
POWER INDICATOR

LOCAL MONITOR OUTPUT
Connect the LOCAL MONITOR
output to the input of the local
computer video monitor.
EQUALIZATION ADJUSTMENT
If a long video cable is connected to the output, turn the EQ
control clockwise until the picture sharpness appears normal.
If a short output cable is connected, or if the picture clarity is
normal, set the EQ control fully counter-clockwise.
FOR BEST PICTURE QUALITY, REMOTE VIDEO MONITOR “OPTIMIZATION” FUNCTION SHOULD BE RUN, IF PROVIDED.
