Installation Considerations

Incorporating a Local Volume Control In a multiroom system there is one indis- pensible device for true convenience—a local volume control. It enables you to adjust the volume of the speakers without leaving the room.

Plan to wire the system so that each pair of speakers has its own volume control built into the wall (think of a volume con- trol as a dimmer switch for sound).

Niles makes a wide range of high perfor- mance indoor and outdoor volume con- trols. They are available in Standard or Decora® style cover plates (just like your light switches and dimmers). Volume con- trols are connected in line with the speak- er, so you must connect the wire from the amplifier to the volume control and then from the volume control to the speaker.

Speaker Wire

Use 2-conductor speaker wire when con- necting CM5PR and CM6PR speakers to your receiver or amplifier. For most appli- cations, we recommend you use 16 or 18 gauge stranded wire. For wiring runs longer than 80 feet we recommend 14 gauge stranded wire. The no-strip termi- nals of the PR speakers will accommodate 12 to 18 gauge wire.

When you run wire inside walls, special jacketing (CL-2 or CL-3) is required to both protect the wire and for fire preven- tion. In some areas conduit is required. For a trouble-free installation, low voltage wire such as speaker wire must be run in accordance with the National Electrical Code and any applicable provisions of the local building code. If you are unsure of the correct installation techniques, wire jacket or type of conduit to use, consult a

TECH TIP

Wire size is expressed by its AWG (American Wire Gauge) number. The lower the number, the larger the wire, i.e. 12 AWG is physi- cally larger than 14 AWG.

professional audio/video installer, your building contractor, or the local building and inspection department.

Incorporating Remote Control

If your stereo system operates with a wire- less Infrared (IR) remote control, consider the advantages of installing a Niles Infrared Extender System. Niles manufactures a number of concealable IR sensors and wall mounted keypads which send a copy of your hand-held remote command via a wire to your main equipment location, where it is repeated to your stereo system. The wire is typically installed with the speaker wire, since the speaker signal and the IR signal will not interfere with each other. This makes almost no difference to the installation time, and the cost of the recommended IR control cable (West Penn D291 or equivalent) is reasonable.

The correct routing for IR control cable is to home run an IR control cable from the main equipment location beside the speaker wire to the planned volume con- trol location; and then on to the proposed sensor location. The combination of IR control cable and speaker wire enables a programmable Niles IntelliPad® to be installed at a later date (the IntelliPad has a convenient speaker mute feature in addi- tion to automating and controlling your stereo system). An IR sensor is best placed where it is convenient for you to point the hand-held remote. Both an IntelliPad and an IR sensor can be connected in one room with one home run IR control cable.

Insulation Behind The Speaker

For best performance from your speakers lay a batten of fiberglass insulation (example: R-19 un-batted insulation) on top of the speaker. Try to keep the same amount of insulation for each speaker, particularly in the same room, for consis- tent bass response.

CM6PR, CM5PR specifications

Niles Audio, a renowned name in the audio industry, introduces the CM5PR and CM6PR, both part of their premium in-ceiling speaker range designed to deliver exceptional sound quality in any environment. These models are engineered for customers who prioritize both aesthetic appeal and superior acoustics in their home audio systems.

The CM5PR features a 5.25-inch polypropylene woofer, delivering a well-balanced sound profile that is rich in detail across the entire audio spectrum. Coupled with a 1-inch aluminum dome tweeter, it provides crisp highs and smooth midrange tones, making it an ideal choice for music enthusiasts and movie lovers alike. The CM6PR, on the other hand, ups the ante with a larger 6.5-inch polypropylene woofer, enabling it to deliver even deeper bass response. The tweeter remains consistent, ensuring both speakers provide uniform sound quality throughout different rooms.

One of the standout technologies behind the CM5PR and CM6PR is the patented IN-CEILING speaker design, which minimizes sound distortion while providing a broad dispersion pattern. This enables a more immersive listening experience, as the speakers can fill the room with clear sound regardless of the listener's position. The speakers are also equipped with a unique speaker grille that can be painted to match the room decor, making them blend seamlessly into any environment.

Furthermore, both models come with adjustable tweeter and woofer controls that allow users to customize the sound to their liking. This is particularly beneficial for rooms with challenging acoustics, where fine-tuning can lead to significantly improved audio performance.

Installation is simplified by their direct-connect system that allows for quick integration into existing audio systems. The CM5PR and CM6PR speakers are compatible with a wide range of amplifiers and receivers, making them versatile choices for various setups.

In terms of durability, Niles Audio has designed these speakers with a moisture-resistant construction, making them suitable for installation in humid areas such as kitchens and bathrooms without compromising sound quality.

In summary, the Niles Audio CM5PR and CM6PR speakers are exceptional choices for anyone looking to enhance their home audio experience while ensuring aesthetic harmony with their living spaces. With their advanced technologies and thoughtful design features, they set a standard in in-ceiling audio solutions.
