DESCRIPTION

The Extron GLI 2000 Series of heavy duty Ground Loop Inhibitors offer reliable, simple solutions for A/V system ground loop problems. The GLI 2000 Series' compact design and rugged construction make them ideal solutions for staging applications where mobility and ease of handling are required. Each model comes standard with protective rails which guard connectors from damage. This flexibility in design allows them to be mounted virtually anywhere including in a rack or road case, near the projector, or in/under furniture.

The GLI 2000 series is available in two models: a five-BNC version for all signal types from RGBHV down to composite, and a two-BNC version for S-video and composite video. GLI 2000 Series products are able to handle even the highest frequency signals and various cable lengths without signal degradation.

GLI 2000 Series products are designed for applications that experience ground loop and interference problems, such as those found in convention centers, hotels, or other large buildings. These problems occur when separate grounds, carrying different loads, are "looped" together by sources and displays within an A/V system, resulting in hum bars — 50- or 60-cycle noise. Hum bars can be described as thick, horizontal background bars rolling vertically through the displayed image. This problem is most common when a projector and its signal source(s) 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 GLI 2000 Series can save hours of troubleshooting and unnecessary rewiring by providing video hum suppression for systems where it is impractical to connect all equipment to the same ground — virtually eliminating hum bars, common-mode noise, and other visible effects caused by improper grounding in video systems.

The GLI 2000 family of products uses proven passive technology and high performance components that provide high core saturation voltage capabilities for even the worst ground loop problems. The GLI 2000 Series products do not require an external power supply as they are non-powered. This enables them to be added anywhere in a system. By using innovative technology, the GLI 2000 Series is effective in solving the majority of video grounding problems.
