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.

INSTALLATION CONSIDERATIONS (CONTINUED)
TYPE OF SPEAKER WIRE (CONTINUED)
aluminum, or Romex wire with an IM volume control. For speaker-wire runs within walls, most U.S. states and municipalities
require a special type of speaker wire with a specific CL fire rating, such as CL-2 or CL-3. Consult your Niles dealer, building
contractor, or local building-inspection department if you aren’t sure what kind of wire is best for your application.
MOUNTING LOCATIONS
Some states or municipalities allow installation of devices such as Niles speaker volume controls in the same junction box
as 110V devices, with a low-voltage partition between the devices. We do not recommend this, because speaker wires can
act as an antenna for electrical noise. Locating speaker wires too close to a light switch or dimmer may cause the speakers
to emit a popping or buzzing sound. If you must locate the volume control near electrical devices, install it in a separate
metal junction box, ground the box to the electrical-system ground, and route the speaker wires several feet away from the
electrical wiring.
