Niles Audio IW2770LCR Installation Considerations Continued, Rubber gloves and protective eyewear

INSTALLATION CONSIDERATIONS (CONTINUED)

■Phillips screwdriver set

■Cable ties

■Pencil

■Level

■Rubber gloves and protective eyewear

Before starting the installation, please observe the following precautions:

■Turn off all system power before making any connections

■Always wear protective eyewear when using tools

■Make sure hands are clean before installation

■Wear gloves when working with fiberglass insulation

RECOMMENDED AMPLIFIER POWER

For satisfactory performance, we recommend using an amplifi er with a power rating of 15 to 125 watts. Most loudspeakers are not damaged by large amplifi ers, but rather by small amplifi ers. If your system is playing loud music, a small amplifi er will run out of power very quickly and can create damaging “clipping” distortions. A more powerful amplifi er will play at the same volume without distorting. See OPERATION on page 11 for more information about amplifi er clipping distortion.

LOUDSPEAKER WIRE

Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or amplifi er. For most applications, we recommend using 16-gauge wire. For wiring runs longer than 80 feet, we recommend 14-gauge wire. The spring- loaded terminals will accommodate up to 12-gauge wire directly. Larger sizes can be accommodated via pin connectors. When running wire inside walls or ceilings, use special jacketed cable (CL-2 or CL-3) to protect the wire and to meet local electrical and fi re codes. In some areas, conduit is also required. For a trouble-free installation, low-voltage wire such as loudspeaker 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 professional audio/video installer, building contractor, or the local building and inspection department.

TECH TIP

Wire size is expressed by its AWG (American Wire Gauge) number – the lower the number, the larger the wire. For example, 12 AWG is physically larger than 14 AWG.
