ABOUT YOUR DISTRIBUTION AMPLIFIER 2

The DA1222AT is a 1-in 2-out RGBHV high- resolution video distribution amplifier. It allows the connection of a single video source from a computer or interface to one or two monitors or projectors capable of handling the source resolution and scan frequency.

The DA1222AT offers a minimum bandwidth of

Though primarily designed to pass an RGBHV signal format, the DA1222AT can also pass RGBS, RGsB, Component Video (Y, R-Y, B-Y), S- Video (Y/C), and Composite Video by using the appropriate channels.

The DA1222AT uses an internal 110/220 V switchable power supply. It can be rack-mounted
