DESCRIPTION

The Extron ADA 2/GLI 350 HV is a one input, two output RGB and sync analog distribution amplifier with a built-in GLI 350 ground loop isolator. The ADA 2/GLI 350 HV is compatible with any computer source that runs RGsB, RsGsBs, RGBS, and RGBHV. The ADA 2/GLI 350 HV has a 350 MHz (-3 dB) RGB video bandwidth and two buffered outputs for connecting a personal computer or a high resolution BNC output workstation to two compatible data or graphic projectors or monitors with BNC inputs. The ADA 2/GLI 350 HV can also connect to system switchers for preview monitoring.

The ADA 2/GLI 350 HV is designed for applications that experience ground loop and interference problems, such as those found in convention centers, hotels, or other large buildings. These occur when separate grounds, carrying different loads, are "looped" together by sources and displays within an A/V system, generating 50- or 60-cycle noise and resulting in "hum" bars. "Hum" bars can be described as thick background bars rolling vertically through the displayed image. This problem is most common when a projector and its signal source or sources are powered from two different power-ground systems that are separated by significant distance.

One solution is to have all system components powered from the same ground, but this is not always a possible or cost-effective solution. The ADA 2/GLI 350 HV can save hours of troubleshooting and unnecessary rewiring by providing electrical isolation for systems where it is impractical to connect all equipment to the same ground — stopping the loop and virtually eliminating "hum" bars and common mode noise caused by improper grounding in video systems.
