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 PR speakers to your receiver or
amplifier. For most applications, we rec-
ommend you use 16 or 18 gauge stranded
wire. For wiring runs longer than 80 feet
we recommend 14 gauge stranded wire.
The no-strip terminals 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
professional audio/video installer, your
building contractor, or the local building
and inspection department.
Incorporating a Remote Control
If you are planning to use a stereo system
with a hand held IR remote control, con-
sider the advantages of installing a Niles
IR Repeater system. You are able to con-
trol all of the functions of your system
from the room via the remote pair of
speakers. Niles makes a number of IR sen-
sors which install in the wall, in the ceiling,
in cabinetry, on tabletops, or even behind
the grille of your Niles MP speakers.
An IR sensor requires that a 2-conductor
shielded wire (West Penn D291 or equiva-
lent) be home run from each sensor loca-
tion to the main equipment location. This
wire is normally run beside the speaker
wire at the same time. Typically, the sen-
sor is placed in a location that faces your
listening position. Most remote controls
will have an effective line of sight range of
18 to 30 feet with any Niles sensor placed
in a wall, ceiling, on a cabinet or tabletop.
However, when you place a Niles MS-1
MicroSensor™ behind the perforated alu-
minum grille of a speaker the effective
range is reduced to 9 to 15 feet.
Insulating the Wall Cavity
For best performance from your speakers fill
the wall cavity behind the speaker with
fiberglass insulation (e.g. R-19 unbated insu-
lation). Try to keep the same amount of
insulation for each speaker, particularly in
the same room, for consistent bass response.

Installation Considerations
TECH TIP
Wire size is expressed by its AWG (American Wire
Gauge) number. The lower the number, the larger
the wire, i.e. twelve AWG is physically larger than
fourteen AWG.
