Galil 2-C - Getting Started
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerav.com/downloads/Galil 2-C to check for up-to-date
user manuals, application programs, and to check if firmware upgrades are
available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighbouring electrical appliances that may adversely
influence signal quality
Position your Kramer Speakers away from moisture, excessive sunlight and
dust
Note that you need to use external equalization to comply with the EN 54-24
standard.
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
Do not open the housing of the speaker; doing so may reduce the
quality of the sound.

2.2 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims
to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country go

Galil 2-C - Overview
3 Overview
The Galil 2-C is a 2.5” full-range high-performance fireproof closed-back speaker
with ceramic terminals and a plastic self-extinguishing back-can. The Galil 2-C is
specially designed to meet the requirements for fire alarm systems in public
spaces.
The Galil 2-C speaker features:
A multi-tap power transformer for selecting 8Ω (bypassing the transformer) or
70V/100V power settings that are suitable for an array installation
10W RMS power
Intelligible and supreme clarity for both sound and music
A thermal fuse that prevents it from burning and damaging the amplifier so
that if one of the speakers in an array installation malfunctions, the other
speakers can continue working undisturbed
Heat-resistant wires that can endure high temperatures
Ceramic Terminal Block which is heat resistant at high temperatures
Two 20.5mm knockout holes and two 11mm knockout holes on the back-can
for passing the cables through via grommet/cable gland
Two spring clamps for quick and easy ceiling installation
An ABS enclosure which makes it a light-weight speaker

4 Installing the Galil 2-C Closed-back Ceiling
Speakers
This section explains how to install the Galil 2-C, that is:
Choosing the best place to locate your speaker (see Section 4.1)
Cutting the ceiling tile (see Section 4.2)
Mounting a Speaker (see Section 4.3)
Setting up an array installation (see Section 4.4)
Painting the speakers (see Section 4.5)
4.1 Choosing the Best Location
Ideally, locate the speakers above the main listening area. Before doing so, be sure
that:
The desired location is free of obstructions, such as electrical piping, AC
ducts or water lines, and so on
There is enough space behind the mounting surface for the speakers
The rear side of the speaker is not blocked by wall studs or other objects
4.2 Cutting the Ceiling Tile
To cut the ceiling tile, do the following:
1. Print the cutout template from our Web site and make sure that the template
size is correct (12.6cm in diameter).
2. Cut the template.
Keep the cutout template for later use as a mask, as you may want to paint the speakers
(see Section 4.5)
3. Mark the opening in the correct location by tracing the hole in the template.
4. Cut out the hole according to the template or with a circular cutter set to the
appropriate cutout size.
Initially, you can cut a smaller area inside the marked hole just to be sure that the space
above the speaker is clear

5. Route the wiring from the amplifier to the speaker’s cutout hole, taking care
not to place them next to electrical wires or at least at a distance of about
two feet from an AC line.
Do not nail or staple the speaker wires.
4.3 Mounting the Speaker
To mount the speaker
1. Remove the grille using a grille remover device, and adjust the speaker to
the appropriate tap setting (see Figure 2).
Figure 2: Adjust Tap Selector
2. Reattach the grille:
Push the grille fastener into the hole in front of the baffle
Press the grille into place until the front of the grille is flush with the rim
of the baffle
Check that the grille is securely seated
3. Remove the back-can by gently pushing the two snaps in the snap holes
with a screwdriver.
4. Punch out a knockout hole (a small or a large one) that fits the size of the
grommet/cable gland you are about to use.
The speaker cable should fit the grommet/cable gland with minimum space
left (see Figure 3).
Make sure you use a UL94 V-0 compliant grommet/cable gland.

Figure 3: Grommet/Cable Gland Installation
5. Mount the grommet/cable gland and pass the cables through.
6. Connect the cables to the speaker (see Figure 5 and Figure 4). Connect the
positive (+) red cable to the + terminal and connect the negative (-) black
cable to the –terminal.
Figure 4: Ceramic Terminal Pinout
You can connect the speakers in either of the two following possible layouts:
Wiring in parallel: when one input connector is removed, subsequent
speakers will remain connected (see Figure 5)
Daisy-chaining: when one input connector is removed, subsequent
speakers will be disconnected (see Figure 5)
For Array installation, we recommend that you connect to the speaker by
passing the audio cable through a second knockout hole.

Figure 5: Galil 2-C Schematic Diagram
7. Snap the back-can in place.
8. Push the spring clamps up as close to the back-can as possible and insert
the speaker through the cutout hole.
Once inside, the springs are released and clasp the ceiling (from the inside).

4.4 Setting up an Array Installation
When installing Galil 2-C in an array installation layout, you have to define the
distance between speakers as well as the layout pattern (square or hexagonal).
The distance between speakers is set according to the speakers’ dispersion angle,
the uniformity of the coverage desired and the budget.
The coverage angle of the speaker determines the coverage area and the number
of speakers required in the array installation. Two patterns are usually used for
array installations, square (see Figure 7) or hexagonal (see Figure 8), depending
on the shape of the installation area. The speakers are positioned according to their
coverage area.
Figure 7: Square Layout
Figure 8: Hexagonal Layout
You can set the power on each speaker to get the desired power level in different
installation areas.

4.5 Painting the Speaker
You can paint the speakers before or after they are installed.
When painting before installation:
Clean the rim and grille with mineral spirits or other light solvent that is
unlikely to damage the surface
Spray with color by holding the spray can at an angle of 45
When spraying the grille, take care not to clog the holes in the grille
as this will greatly reduce the sound quality of the speakers.
When painting after installation:
Use the circle that you cut out of the template as a paint mask
After you finish painting, remove the paint mask
