3 Overview The ESD™ (Equal Sound Dispersion) Ceiling Speaker is a high- performance complete K-overage ESD ceiling speaker that can be mounted on the ceiling and appears as a suspended ceiling tile. The ESD ceiling speaker is constructed with a central driver and four pivoting tweeters and is housed in an enclosed shallow enclosure. The Kramer complete K-overage ESD provides unmatched sound response in a suspended ceiling device for the professional (PRO) and educational (EDU) markets.

4 Installing the ESD Ceiling Speaker This section explains how to install the ESD Ceiling Speaker, that is: 4.1 • Choosing the best place to locate your speaker (see Section 4.1) • Connecting the wires (see Section 4.2) • Determining the number of speakers (see Section 4.3) • Preparing the speaker for operation (see Section 4.4) • Installing the tile size speaker (see Section 4.5) • Installing the half-tile size speaker (see Section 4.
4.3 Determining the Number of Speakers Needed and their Location When installed in a room with a standard ceiling height of 2.7m (8.8 feet), the optimal distance between the speakers is about 10 meters. The speaker should be installed lengthwise relative to the shape of the room. The example in Figure 4 shows the ESD Ceiling Speaker installed in a 10m x 5m room. A 10m x 5m room size requires only one ESD speaker for full room coverage rather than four standard ceiling speakers.
• If the size of the room requires more than one speaker, use two mono speaker models.
4.4 Preparing the ESD Ceiling Speaker for Operation Once the location of the speaker is fixed, prepare the speaker for operation as follows: 1. Move each of the pivoting tweeters outward in an angle that is suited to the room shape and size. 2. Run the wires from the amplifier through the ceiling. 3. Remove the ceiling tile at the place where you plan to install the speaker. 4. Connect the speaker wires to the speaker terminals (see Figure 3) from the adjacent ceiling tile opening. 5.
Figure 7: Fitting the Tile Size Speaker 2. Secure the speaker by connecting the speaker support ring to an independent secure ceiling anchor point (see Figure 8) as appropriate. The anchor prevents the speaker from falling if the tile itself comes out or falls apart.
3. If required, daisy-chain the next speaker (see Section 4.3). Note: Do not over-tighten the screws. It may cause damage to both the speakers and the surface. 4.6 Installing the Half-Tile Size Speaker When installing the half-tile size model: 1. Remove the ceiling tile. 2. Cut the ceiling tile in half (to 30x60cm). 3. Place the ceiling mounting bracket (supplied with the half-tile unit only) between the ceiling rails, as illustrated in Figure 9. Figure 9: Placing the Ceiling Mounting Bracket 4.
Figure 10: Fitting the Half-Tile Size Speaker 5. Replace half of the ceiling tile (see Figure 11). Figure 11: Replacing the Ceiling Tile 6. Secure the speaker by connecting the speaker support ring to an independent secure ceiling anchor point (see Figure 8). The anchor prevents the speaker from falling if the tile itself comes out or falls apart.
