Galil 8-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 8-C - Overview

3 Overview

The Galil 8-C consists of a pair of high performance closed back speakers.

Mount your Galil 8-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 8-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 1shows an example of how the Galil 8-C 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 8-C Closed-back Ceiling

Speakers

This section explains how to install the Galil 8-C, 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
