ABOUT YOUR DISTRIBUTION AMPLIFIER 2

The DA1904SX is a special distribution amplifier that offers a 15-pin HD input, a RGBHV main output (on 5 BNC connectors), and a 15-pin HD loop output. This product provides a low cost solution and connector adapter needs. This configuration is very similar to that which is used

and loop output. Each monitor is fed from the RGBHV output. In this system, the DA1904SX units may receive their origin feed from an output module (DA1902SX).

for interfacing VGA type signals. These signals feed RGBHV to a main presentation display on BNC connectors, which in turn feed the local monitor from the loop output. The DA1904SX can be used in this method although it does not provide other interfacing features, such as Sync Processing, Horizontal Positioning, etc.

The DA1904SX is primarily designed for RGBHV format signals, but it is also capable of passing RGBS and RGsB. The DA1904SX is extremely compact and may be mounted to furniture or other surfaces using optional hardware.

In addition to being used for small distribution applications with two displays, the DA1904SX also

acts as an output 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, up to thirty DA1904SX units may be installed at each monitor location along the bus, which is created by using VGA-type cables connected to the 15-pin HD input
