ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The
DA1203RM
Distribution Amplifier is designed
to allow the connection of a single computer or
other video source to as many as three scan-rate
compatible display devices.
Though primarily designed to pass RGBS format
signals, the
DA1203RM
can also pass RGsB,
Component Video (Y, R-Y, B-Y), S-Video (Y/C),
and Composite Video by using the appropriate
analog channels (Red, Green, Blue).
The analog channels (Red, Green, Blue) are
designed to pass video levels up to 1.5V p-p
offering a 0.15% differential gain and 0.16 degree
differential phase to assure the highest quality
video signal.
The
DA1203RM
offers switches for Gain, Sync
Level, and Sync Polarity. The Gain Switch boosts
the output of the amplifier by 35% for use, with long
cable runs. The
DA1203RM
uses AGC (automatic
gain control) circuitry, which converts all incoming
sync levels to either 4V p-p or 2V p-p. This AGC
circuitry is selectable with the Sync Level switch.
This enables it to be compatible, with current and
older display equipment. The Sync Polarity switch
reverses the polarity of the incoming sync for
compatibility with various displays.
The
DA1203RM
Distribution Amplifier is a state-of-
the-art product with a video bandwidth of 350 MHz,
enabling it to remain transparent to the video signal
passing through it. Each output is individually
buffered and is not affected by other output
loading.
The
DA1203RM
offers an internal 90-140/200-
240V power supply and can be rack mounted using
optional accessories hardware (
DA1299RM
– rack
ears for single unit and
DA1298RM
– rack shelf for
two units side-by-side).
