3 Overview The Kramer Tavor 8-T Active Ceiling Speaker is an active high-performance complete K-overage™ ESD ceiling speaker that can be mounted in the ceiling and appears as a suspended ceiling tile. The Tavor 8-T accepts 3 line level stereo inputs and amplifies them using a built-in amplifier. Each audio input level can be adjusted independently and the overall volume can be adjusted via the master volume trimmer.

4 Installing the Tavor 8-T This section explains how to install the Tavor 8-T, that is: 4.1 Choosing the best place to locate your speaker (see Section 4.1) Determining the location of the speaker (see Section 4.2) Preparing the speaker for operation (see Section 4.3) Installing the tile size speaker (see Section 4.4) Choosing the Best Location Ideally, locate the speakers above the main listening area.
4.2 Determining the Location of the Tavor 8-T When installed in a room with a standard ceiling height of 2.7m (8.8 feet), the optimal distance between 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 Tavor 8-T installed in a 10m x 5m room. This example also shows how the Tavor 8-T can actually replace several standard speakers in a room. Figure 4: Tavor 8-T vs.
4.3 Preparing the Tavor 8-T 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 through the ceiling. 3. Remove the ceiling tile at the place where you plan to install the speaker. 4.
5. Set the audio level independently per input and, if required, set the overall audio level via the MASTER VOLUME trimmer. 6. Place the speaker temporarily in place, and test the audio quality. 7. If you are not satisfied, change the position of the tweeters, set the audio levels and check the audio quality again until you are happy with the results. 8. Fit the speaker grille over the speaker underside and tighten with screws. To install the tile size speaker, see Section 4.4. 4.
2. Secure the speaker by connecting the speaker support ring to an independent secure ceiling anchor point (see Figure 7) as appropriate. The anchor prevents the speaker from falling if the tile itself comes out or falls apart. Figure 7: Securing the Speaker to a Ceiling Anchor Point i 12 Do not over-tighten the screws. It may cause damage to both the speakers and the surface.
