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.
