About the GLI 350xi and ADA 2/GLI 350xi
This manual contains information about the Extron 
GLI 350xi ground loop isolator and the Extron ADA 2/GLI 
350xi distribution amplifier with built-in ground loop isolator. 
Extron ground loop isolators eliminate "hum" bars and common 
mode noise caused by improper equipment grounding in video 
systems. 
Both models are rack and furniture mountable. The GLI 350xi 
is a one-input, one-output model; the ADA 2/GLI 350xi is a 
one-input, two-output unit. The terms "GLI" and "ground loop 
isolator" are used interchangeably in this manual to refer to 
either model.
