FCC Class A Notice  
This equipment has been tested and found to comply with the limits for a Class A digital device,  
pursuant to part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this  
device may not cause harmful interference, and (2) this device must accept any interference received,  
including interference that may cause undesired operation. The Class A limits are designed to  
provide reasonable protection against harmful interference when the equipment is operated in  
a commercial environment. This equipment generates, uses, and can radiate radio frequency  
energy and, if not installed and used in accordance with the instruction manual, may cause harmful  
interference to radio communications. Operation of this equipment in a residential area is likely to  
cause harmful interference, in which case the user will be required to correct the interference at his  
own expense.  
This unit was tested with shielded cables on the peripheral devices. Shielded cables must be used  
with the unit to ensure compliance with FCC emissions limits.

Introduction  
About the GLI 350xi and ADA 2/GLI 350xi  
GLI 350xi & 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.  
Features  
NTSC, PAL, and SECAM compatible — Both models are  
NTSC, PAL, and SECAM compatible with computers  
and other high resolution sources that output RGBHV,  
RGBS, RsGsBs, and RGsB video. The RGB channels are  
also compatible with low resolution video signals in  
component, S-video, and composite video formats.  
Chapter Two  
Bandwidth — 350 MHz (-3 dB) RGB video bandwidth, fully  
2
loaded  
Video input horizontal frequency range — 15 kHz - 135 kHz  
Mounting options — The GLIs are rack and furniture  
mountable.

Elevated operating ambient temperature — If the unit  
is installed in a closed or multi-unit rack assembly, the  
operating ambient temperature of the rack environment  
may be greater than room ambient temperature.  
Therefore, install the equipment in an environment  
compatible with the maximum ambient temperature  
(Tma = +104 °F, +40 °C) specified by Extron.

Reduced air flow — Install the equipment in a rack so that  
the amount of air flow required for safe operation of the  
equipment is not compromised.

Mechanical loading — Mount the equipment in the rack so  
that a hazardous condition is not achieved due to uneven  
mechanical loading.  
GLI 350xi application example  
Circuit overloading — Connect the equipment to  
the supply circuit and consider the effect that circuit  
overloading might have on overcurrent protection and  
supply wiring. Appropriate consideration of equipment  
nameplate ratings should be used when addressing this  
concern.  
5.  
Reliable earthing (grounding) — Maintain reliable  
grounding of rack-mounted equipment. Pay particular  
attention to supply connections other than direct  
connections to the branch circuit (e.g., use of power strips).

Rack mounting  
6" Deep Rack Shelf  
The ground loop isolators can be mounted in a rack shelf using  
the optional RSU 129 1U 9.5" deep universal rack shelf kit  
(Extron part #60-190-01) or the RSU 126 1U 6" deep universal  
rack shelf kit (Extron part #60-190-10), as follows.  
1.  
If feet were installed on the bottom of the GLI, remove  
them.  
2.  
Place the GLI on one half of the 1U (one unit high, 19"  
wide) rack shelf. Align the front of the GLI with the front  
of the shelf, and align the threaded holes on the bottom of  
the GLI with the holes in the rack shelf.

Under-furniture mounting  
GLI 350xi & ADA 2/GLI 350xi  
The GLI 350xi or ADA 2/GLI 350xi can be mounted under  
furniture, such as a desk or table, using the optional MBU 125  
mounting kit (Extron part #70-077-01), as follows.  
1.  
If rubber feet were previously installed on the bottom of  
the unit, remove them.  
2.  
Attach the mounting brackets to the GLI with the provided  
machine screws.

Drill four pilot holes, each 3/32" (2 mm) in diameter by  
1/4" deep (6.3 mm) in the mounting surface at the marked  
screw locations.  
Insert #8 wood screws into the four pilot holes. Tighten  
each screw into the mounting surface until just less than  
1/4" (6.3 mm) of the screw head protrudes.  
Align the mounting screws with the slots in the brackets  
and place the unit against the surface, with the screws  
through the bracket slots.  
Slide the unit slightly forward or back, then tighten all four  
screws to secure the unit in place.
