The DA1920SX is a high-resolution 1-in, 2-out Computer Video Amplifier-Transmitter. It is designed to allow the connection of a single VGA/SVGA/XGA/UXGA source to a local monitor through an HD VGA 15-pin female connector. The DA1920SX is also connected to the DA1921SX Distribution Amplifier-Receiver through an RJ-45 plug and a category 5 cable with lengths up to 400 feet. The DA1920SX converts single ended video source signals into differential signals.

The DA1921SX converts differential signals to single ended video signals, which distributes this source to two displays. Offering a minimum video bandwidth of 300 MHz and using equalization circuit, the DA1920SX allows very high-resolution video signals to pass without degradation to the image quality. The Local Monitor Output of the DA1920SX is pre-compensated for up to 12 feet of high-resolution coaxial-type VGA cable. With its compact and user friendly design, the DA1920SX is perfect for audiovisual installations, where a single computer sends signals using inexpensive, thin and light category 5 cable.
