GLI 350 and ADA 2/GLI 350 HV
Installation
The GLI 350 and the ADA 2/GLI 350 HV are ground loop
isolators that eliminate the hum bars and mode noise associated
with improper equipment grounding in video systems. The
GLI 350 is a one-input, one-output dedicated ground loop
isolator. The ADA 2/GLI 350 HV is a one-input, two-output
distribution amplifier with ground loop isolation.
Use the following steps to install the GLI 350 or the
ADA 2/GLI 350 HV ground loop isolator.
Installation Procedure
1 Install the GLI 350 or ADA 2/GLI 350 HV ground loop
isolator near the display device(s), rather than near the
signal source device. See the example diagrams.
2 Connect the RGBS or RGBHV source cables to the ground
loop isolator’s BNC inputs.
3 Connect the ground loop isolator’s BNC outputs to the
display device(s).
4 Plug the ground loop isolator to the same power source as
the display device(s).
5 The GLI 350 has 3 gain controls located on the bottom of
the case to adjust the red, green, and blue output signals
individually. To access the gain controls on the
ADA 2/GLI 350 HV, the case must first be opened.
