Galil 4-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.kramerelectronics.com/support/product_downloads.asp

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 neighboring electrical appliances that may adversely

influence signal quality

Position your Kramer Speakers away from moisture, excessive sunlight and

dust

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.

Galil 4-C Overview

3 Overview

The Galil 4-C Closed-back Ceiling Speaker consists of a pair of high performance

closed back speakers. Mount your Galil 4-C speakers to the ceiling in one of two

ways: either directly onto the ceiling or, for added protection, secure the speakers

safely, using our ceiling mounting kit that is provided free (see Section 5.3).

The Galil 4-C speakers feature a multi-tap power transformer for selecting 8Ω

(bypassing the transformer) or 70V/100V power settings that are suitable for an

array installation.

Figure 1 shows an example of how the Galil 4-C Closed-back Ceiling Speaker can

be installed in a boardroom setup:

Each Closed-back Ceiling speaker is supported by a C-ring and two tile rails. The tile

rails prevent the speakers from falling if the tile itself comes out or falls apart, as

their ends catch onto the T-grid. When mounting onto the ceiling tiles, use both

supports. When mounting onto a sheetrock ceiling, the C-ring alone is used to

reinforce the ceiling material.

Be sure that the tiles can support the speaker. Smaller sized tiles or

fiberglass-type tiles cannot support the weight of the speakers.

When this is the case, the speakers will need additional support.

5 Installing the Galil 4-C

This section explains how to install the Galil 4-C closed-back ceiling speakers,

that is:

Choosing the best place to locate your speakers (see Section 5.1)

Cutting the ceiling tile (see Section 5.2)

Mounting the speakers (see Section 5.3)

Setting up an array installation (see Section 5.4)

Painting the speakers (see Section 5.5)

5.1 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

5.2 Cutting the Ceiling Tile

To cut the ceiling tile, do the following:

1. Remove the circle in the supplied template.

Keep this template for later use as a mask, as you may want to paint the speakers (see

Section 5.5)

2. Mark the opening in the correct location by tracing the hole in the template.

3. 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 speakers is clear
