The SVL-2 includes impedance correction circuitry which
protects your receiver or amplifier from low impedance
loads. The circuitry assures that your receiver or amplifier will
see a safe operating load, even when two pairs of 4-ohm
speakers are playing at the same time.
Type of Speaker Wire
For most applications, we recommend you use 16 or 18
gauge stranded copper speaker wire for the SVL-2 connec-
tions. For wiring runs longer than 80 feet, 14 gauge wire is
recommended. Using speaker wire larger than 14 gauge for
the SVL-2 connections is not recommended—the wire may
not fit into the connectors. Never use solid-core, aluminum,
or "Romex" type wire with the SVL-2. When running speaker
wires inside walls, most states and municipalities in the U.S.
specify that you must use a special type of speaker wire.
Usually, the requirement is that the wire has a specific "CL"
fire rating, such as "CL-2" or "CL-3". Consult your Niles deal-
er, building contractor, or local building and inspection
department if unsure about which type of wire is best for
your application.
Avoiding Interference
Speaker wires can act as an antenna for electrical noise.
Locating speaker wires too close to a light dimmer or switch
may cause a "buzzing" or "popping" sound to be heard
thought the speakers. If you must locate the SVL-2 wiring

Wire size is
expressed by it's

number. The lower
the AWG number,
the larger the wire,
i.e., 12 AWG wire is
physically larger
than 14 AWG.
