Introduction Thank you for choosing a Multipurpose Ceiling Mount Loudspeaker from Niles. With proper installation and operation, you'll enjoy years of trouble-free use. The MP Multipurpose group of ceiling mount loudspeakers offers speakers designed for utility and flexibility. These are quality "general purpose" speakers.
Hole Saving Bracket Available as an optional accessory, CM5 Series, CM6 and CM8 Series New Construction Brackets can be installed as a “hole-saver” before the drywall goes up. The drywall contractor cuts the holes as the drywall is installed, reducing installation time and minimizing the chance for lost wires. Installer Selectable Acoustic Fine Tuning (CM8MP Only) Installers can select to de-emphasize the bass or treble by 2dB to accommodate reflective surfaces and corner loading.
Plan to wire the system so that each pair of speakers has its own volume control built into the wall (think of a volume control as a dimmer switch for sound). Niles makes a wide range of high performance indoor and outdoor volume controls. They are available in Standard or Decora® style cover plates (just like your light switches and dimmers).
The rule of thumb is to add one pair of speakers for every 100 to 200 square feet of listening area. Curiously, this is not so that you can play the music louder, but so that you can play it softer! When you have only one pair of speakers in a large room you will notice that when the sound is perfect in one part of the room, it is too loud near the speakers.
Running the Speaker Wire in New Construction If you have doubts about whether you are capable of installing a Niles ceiling mount loudspeakers, consult a Niles dealer or professional installer. They have special tools, techniques, and experience to make the impossible possible. The installer can provide you with an estimate before any work is done. Scheduling and Preparation Plan to schedule the speaker wiring after the electrical wiring is finished.
Volume Control Location Stereo Location Figure 8 allel to power cables at least three feet away. To find exactly where an electrical cable is routed, try inspecting the inside of the wall by turning off the breaker for a particular power outlet or switch, removing the cover plate and switch or receptacle, and shining a penlight into the wall. If you have access to an attic or basement space you can quickly see which part of the wall space is free of obstructions (See Figure 7).
Insulating the Wall Cavity If feasible, fill the wall cavity with insulation at this point. Mounting The New Construction Bracket The hole saving bracket enables a faster and cleaner final installation of the speaker. It forces the drywall installer to cut out the speaker hole for you and provides wire ties for the speaker wire, reducing the risks of accidental loss or movement of the wire.
1. If it is possible to lay a batt of insulation into the ceiling cavity do so. Remember to use equal amounts of insulation for each speaker. NOTE: The screws will be easier to turn if you “prime” them first. Before installing each speaker, turn the screws in and then turn them back out to their original positions. 7. Direct the Tweeter. The tweeter is directed by gently pushing on the edge of the tweeter grille. It will move 20° in 2.
Specifications Listening at Higher Volumes It requires more power to achieve a reasonable volume of sound in a large room than it does in a small room. It is possible (even if you are not a teenager) to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion.
