The DA1905GL is a multi-purpose RGBHV line driver, ground loop isolator, and sync processor. As a Line Driver, the DA1905GL offers a single ouput (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. Used to compensate for loss over long runs of coaxial cable, the DA1905GL may be installed alone or with an interface, or iwth additional DA1905GL units, depending on system requirements. Typically, the DA1905GL might be used at the end of a cable run with an interface at the head-end of the run.
The DA1905GL is engineered for custom signal alignment, enabling it to be modified to handle cable runs of 300ft (91m) or more. The DA1905GL is compact and streamlined, making it easy to fit virtually anywhere in a system.
In an audiovisual system, when different pieces of equipment operating from different power sources are connected, a ground loop can potentially occur, usually causing a hum bar to roll from top to bottom over a display image. Severe ground loops can cause damage to equipment. The DA1905GL is designed for installation between these pieces of equipment to eliminate a ground loop problem. The common mode range of the DA1905GL is +/-2V with a video signal of 1Vp-p. The DA1905GL may also be used as a ground loop isolator for up to three different composite video signals, using red, green, and blue channels.
Ultimately, the DA1905GL acts as a sync processor, allowing you to combine horizontal and vertical sync into composite sync or splits composite sync into separate horizontal and vertical sync.
