ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The DA1902SX is essentially a 1-in 2-out RGBHV
distribution amplifier, which is unique due to the
fact that it offers 5 BNC connectors for the inputs
and two 15-pin HD (VGA - type) connectors for the
outputs. This makes it perfect for special
applications where a RGBHV signal on 5 BNC
connectors is connected to two VGA type monitors.
If desired, the 15-pin HD connectors can also be
adapted to 5 BNC connectors using adapter
cables.
Though primarily designed for RGBHV format
signals, the DA1902SX is capable of passing
RGBS and RGsB signals as well. With its compact
design and very low cost, the DA1902SX makes for
an ideal distribution amplifier in either a small or a
large system.
In addition to being used for applications with two
displays, the DA1902SX also acts as an input
module for the Altinex Serial Distribution System.
This is a system, which uses the concept of
creating a high-resolution video bus in large
distribution applications with many displays. This
system provides a lower cost and a higher
performance alternative to the concept of feeding
home runs (a run of cable) to a single large
distribution amplifier. In the Serial Distribution
System, the DA1902SX is the starting point of the
bus, which feeds up to thirty output modules
(DA1904SX), through its 15-pin HD connectors
with VGA type cables.
