Installation Considerations - Niles PHD30 Installation Manual

INSTALLATION CONSIDERATIONS

WALL MOUNTING
The Niles PHD60/42/30 loudspeaker is equipped with an included wall-mount bracket for quick
and easy installation on a wall. Ideally, a PHD60/42/30 should be placed so that its bracket can
be installed on underlying wall studs. If stud mounting is impractical, dry-wall anchors (rated for
at least 40 pounds) can be used to mount the loudspeaker between studs (see INSTALLING THE
WALL-MOUNT BRACKETS on page 7).
RECOMMENDED AMPLIFIER POWER
For satisfactory performance, we recommend using a home theater receiver (or amplifier) with
a power rating of 10 to 250 watts for the PHD60,10 to 200 watts for the PHD42, and 10 to 150
watts for the PHD30. Most loudspeakers are not damaged by large amplifiers, but rather by small
amplifiers. If your system is playing loud music, a small amplifier will run out of power very quickly
and can create damaging "clipping" distortions. A more powerful amplifier will play at the same
volume without distorting. See OPERATION on page 13 for more information about amplifier
clipping distortion.
LOUDSPEAKER WIRE
Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or amplifier.
For most applications, we recommend using 16- or 18-gauge wire. For wiring runs longer than
80 feet, we recommend 14-gauge wire. The spring-loaded terminals of the PHD60/42/30 will
accommodate up to 12-gauge wire directly. Larger sizes can be accommodated via
pin connectors.
When running wire inside walls or ceilings, always use (CL-2 or CL-3) rated cable. 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.
