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.
