ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The
DA1222AT
is a 1-in 2-out RGBHV high-
resolution video distribution amplifier. It allows the
connection of a single video source from a
computer or interface to one or two monitors or
projectors capable of handling the source
resolution and scan frequency.
The
DA1222AT
offers a minimum bandwidth of
350 MHz and a typical bandwidth of 500 MHz,
allowing it to remain virtually transparent to high-
resolution signals.
Though primarily designed to pass an RGBHV
signal format, the
DA1222AT
can also pass
RGBS, RGsB, Component Video (Y, R-Y, B-Y), S-
Video (Y/C), and Composite Video by using the
appropriate channels.
The
DA1222AT
uses an internal 110/220 V
switchable power supply. It can be rack-mounted
using optional hardware.
The
DA1222AT
uses 5-BNC connectors for each
input and output representing red, green, blue,
horizontal sync, and vertical sync signals.
