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. The DA1904SX provides a low cost solution for these particular distribution and connector adaptation needs. This configuration is very similar to that which is used for interfacing VGA type signals: feeding RGBHV to a main presentation display on BNC connectors and feeding the local monitor from the loop output. In fact, the DA1904SX can be used in this manner (but it does not provide other interfacing features such as Sync Processing, or Horizontal Positioning).

The DA1904SX is primarily designed for RGBHV format signals, but is also capable of passing RGBS and RGsB.

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 — a system that uses the concept of creating a high-resolution video bus in large distribution applications with many displays. This system provides a lower cost, higher performance alternative to the concept of feeding "home runs" to a single large distribution amplifier.

The DA1904SX is extremely compact and may be mounted to furniture or to other surfaces using optional hardware.
