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.

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

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.
