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.

NOTE: All nominal levels are at 10%. Specifications are subject to change without notice.  
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.
