ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The DA1912SX Distribution Amplifier is designed
to allow the connection of one high resolution
RGsB or RGBS source to up two scan rate
compatible monitors or projectors.
Although designed to pass an RGBS signal format,
the DA1912SX can also pass RGsB, Component
Video (Y, R-Y, B-Y), S-Video (Y/C), and Composite
Video by using the appropriate channels. Video
sources must be passed through Red, Green,
and/or Blue channels. The sync channel is not
designed to pass video.
The DA1912SX 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 DA1912SX accepts one input and offers up to
two outputs. Compensation for cable loss is
automatically made for distances up to 100 feet
when set normally, though the DA1912SX can
drive signals through longer runs depending on
source signal resolution and cable quality.
The DA1912SX is supplied with a 9V 500mA
External Power Adapter.
