The Extron
GLI 350xi is an active one-input, one-output ground loop isolator that eliminates
video hum bars and common mode noise caused by improper equipment grounding in video
systems. It provides ground loop isolation for a variety of signals, including RGBHV, RGBS,
RsGsBs, RGsB, component video, S-video, and composite video. The GLI 350xi is designed for
applications in rental and staging, convention centers, hotels or other large buildings, and other
environments where ground loops and video signal interference may occur.
Ground loops arise when there is an electrical potential difference between two inter-connected
electronic devices, such as when a projector and its signal source(s) are powered from two
different power-ground systems that are separated by a significant distance. This causes a
loop current to flow between the two pieces of equipment, resulting in hum bars — 50- or
60-cycle noise that is best described as a series of thick background bars that roll vertically
through the displayed image.
The GLI 350xi provides electrical isolation for systems where it is impractical to connect all
equipment to the same ground. Offering RGB video bandwidth of 350 MHz, the GLI 350xi
is housed in a compact, one-quarter rack width metal enclosure with an attached, external
international power supply.
