The DA1905GL is a multi-purpose RGBHV line driver, ground loop isolator, and sync processor. It offers a single input (5 BNC connectors for RGBHV) and a single output (6 BNC connectors for RGBSHV). It will also accept RGBS, RGsB, component video (Y, R-Y, B-Y), S-video, and composite video signals using the appropriate channels. With a single built-in equalization control, the DA1905GL can easily compensate for cable runs of 350 feet or more. All three R, G, and B channels are adjusted with the single control dial.
The DA1905GL also provides ground loop isolation to prevent hum bars and other artifacts caused by ground loops in a system. The common mode range of the DA1905GL is +/-.7V with a video signal of 1V p-p. (Most ground loops range between +/– 0.05 to 0.5 volts, which is well within the capabilities of the DA1905GL)
The DA1905GL also acts as a sync processor, allowing you to combine horizontal and vertical sync into composite sync or separating composite sync into horizontal and vertical sync. It can pass through a sync-on-Green signal, but does not, however, strip sync from a sync-on-Green signal.
