For proper connection and therefore full enjoyment of your new Phase Technology® speakers, we encourage you to read this owners' manual thoroughly, even if you are very familiar with installing speakers. Speaker placement is very subjective. Placement follows the guidelines for the developers of in-ceiling speakers, yet is also guided by personal preferences. The proper spacing, location and adjustment of in-ceiling speakers are critical for complete enjoyment of your new speakers. This manual covers these topics thoroughly. Choose the appropriate mounting location for each speaker.
NOTE: When deciding upon a location, consider the following:
- Be certain your speaker wires can be run to or are accessible from these locations.
- Make certain the wall or ceiling material is sturdy enough to support the weight and vibration of the speakers.
- It is recommended that our pre-construction rough-in brackets (part number RB21 for CS-6R, CS-6R DVT & CS-6R Point, AC-CS-8R-PCB for CS-8R and RB25 for CS-6R IW) be used whenever possible in new construction.
- Be certain the area behind the speaker is free of obstacles such as wall studs, electrical wiring, pipes, etc.
• Each speaker should be positioned properly, relative to the listening area for good coverage. - Audio performance and room-to-room isolation will be improved if there is some fiberglass insulation placed loosely behind the speaker.
[SPEAKER INSTALLATION]
STEP 1: Using the supplied cutout template, carefully mark the area to be cut out. Using a drywall knife or saw, cut a hole in the drywall and prepare the speaker wires for connection to the speaker terminals. (Fig. 1.1 for CS-6R, CS-6R DVT, CS-6R Point & CS-8R - Fig.1.2 for CS-6R IW).
STEP 2: Remove the grille from the speaker assembly (Fig. 2). If it is necessary to paint the speaker grille to match the ceiling, we recommend that you do so with several light coats of matching spray paint.
STEP 3: Connect the speaker wires to the input terminals on the rear of the speaker, making sure no loose strands are exposed (Fig. 3).
STEP 4: NOTE: For the CS-6R DVT there are several hookup options. For stereo point-source operation, connect the speaker wires to the left AND right channel input terminals on the rear of the speaker (Fig. 4). Make sure no loose strands are exposed. Please make sure to check your hookup polarity for proper operation.
For Surround/Mono: The CS-6R DVT may also be used as a surround speaker for home theater applications. For the SURROUND or MONO mode of operation, connect your speaker wire to either the left OR right channel input as above (Fig. 5). Next, connect 2 jumper wires from this same input terminal to the corresponding input terminals on the opposite side of the speaker. Connect the red positive terminal to opposite red terminal and black negative terminal to opposite black terminal.
This speaker may be set to either the bipole OR dipole mode of operation using the selector switch on the rear panel.
Please note that the speaker is a 4 ohm speaker in this configuration.
STEP 5: Carefully position the speaker in the cutout hole. Using a Phillips screwdriver, rotate the four clamps to secure the speaker to the drywall (Fig. 6). CAUTION: DO NOT OVER-TIGHTEN.
Note: The CS6R Point has an angled baffle which allows the speaker to be pointed toward the listening position. Rotate the baffle in the cutout until it is pointing in the desired direction prior to tightening the clamping screws.
STEP 6: Carefully replace the grille by pressing it into the gap between the flange and the baffle. Enjoy!
[CARING FOR YOUR PHASE TECHNOLOGY SPEAKER]
All Phase Technology® speakers are finished with a high degree of craftsmanship in either hand polished paint or vinyl laminates. We recommend using a lint-free rag with a small amount of glass cleaner to maintain the long-lasting beauty of the finish. Avoid products containing silicones, oils, oil derivatives, or solvents. Use a damp cloth on enclosures finished in vinyl laminates.
[MAINTENANCE AND SERVICE]
Because of Phase Technology's uncompromising quality control programs, it's unlikely that your speakers will ever need service if connected and used as outlined in this Owners' Manual. In the unlikely event that a problem does occur, please contact your Phase Technology® dealer. Your dealer has the necessary factory-authorized parts and trained technicians to quickly restore your speaker to its original performance specifications.
