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 6-C - Overview
3 Overview
The Galil 6-C consists of a pair of high performance closed back speakers.
Mount your Galil 6-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 6-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 6-C can be installed in a boardroom setup:

Galil 6-C - Your Galil 6-C Closed-back Ceiling Speakers
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.

Speakers
This section explains how to install the Galil 6-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 5.4)
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 5.4)
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

4. Route the wiring from the amplifier to the speakers’ cutout holes, 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.
If you are mounting the speakers onto a ceiling tile, remove the ceiling tiles where you plan to install the speakers. Use the template to trace and then cutout the speaker hole over an empty box.
The closed-back ceiling speakers are supported by the ceiling mounting kit (two C-rings and two pairs of 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.
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.
When mounting onto a sheetrock ceiling, the C-ring alone is used to reinforce the ceiling material.
5.3 Mounting the Speakers
To mount the Galil 6-C, do the following:
1. Place the C-ring over the hole cut in the ceiling tile (on the “ceiling” side). Place it around the hole so that the tabs are located in parallel to the tile edges.

2. Place the tile rails on the tile and snap them into the two tabs on the C-ring. Align the rails so that the ends extend over the T-channel grid.
3. Insert a screw through each tab on the C-ring to secure the rails.
4. Connect the speaker wires to the appropriate connector terminals:
PIN 1 and PIN 2 are connected internally and are positive (+) PIN 3 and PIN 4 are connected internally and are negative (-)
Screw the hold-down screws on the connector until tight, using a small screwdriver. You can connect the speakers in the two following possible layouts:
Wiring in parallel: connect the wire pair of the subsequent speaker to
PIN 2 and PIN 3. When one input connector is removed, subsequent speakers will remain connected (see Figure 3)
Daisy-chaining: connect the wire pair of the subsequent speaker to
PIN 1 and PIN 4. When one input connector is removed, subsequent speakers will be disconnected (see Figure 3)
5. Plug the connector into the socket in the terminal cup of the speaker (see
Figure 5).
6. Run the wires through the wires’ opening in the input terminal cover plug and then into the terminal block connector of the speaker.

7. Push the speaker into the ceiling hole until the front baffle rim is leveled with the ceiling.
8. Tighten the mounting tabs by turning the screw counter clockwise (see
Figure 6).
Turning one quarter of a circle rotates the tab outwards; after that the screw is turned to tighten the tabs to the rear side of the ceiling surface
When tightening the mounting tabs, the tabs automatically turn outward, thus clamping the speaker to the wall from its rear side.
Do not over-tighten the screws. It may cause damage to both the speakers and the surface.

9. If required, you can further secure the speaker by connecting the speaker support ring to an independent secure anchor point.
10. Adjust each speaker to the appropriate tap setting before installing the grille (see Figure 7).

11. Install the grilles to the speakers:
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
To remove the grille, insert two bent paper clips into the holes in the grille and carefully pull it down. Repeat this around the perimeter of the grille until it is completely removed.
5.4 Setting up an Array Installation
When installing Galil 6-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 8) or hexagonal (see Figure 9), depending on the shape of the installation area. The speakers are positioned according to their coverage area.

You can set the power on each speaker to get the desired power level in different installation areas.

5.5 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
