Proven and reliable passive technology  
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.  
High core saturation voltage effectively eliminates hum bars and common-mode  
noise caused by ground loops  
Rugged, rack-mountable, metal enclosure with protective guard rails  
10-2000 kHz horizontal frequency range  
No external power required  
Multi-video format compatible  
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 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.  
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.
