not fit into the connectors. Never use solid-core, aluminum,
or "Romex" type wire with the SVL-6. 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 that has a specific
"CL" fire rating, such as "CL-2" or "CL-3". Consult your Niles
dealer, 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
though the speakers. If you must locate the SVL-6 wiring near
electrical devices, route the speaker wires several feet away
from the electrical wiring.

Using the SVL-6 with Tube-Type Amplifiers

Virtually all tube amplifiers must have a load connected at all
times. If the amplifier to be connected to the SVL-6 is a tube
amplifier, be sure to always have at least one pair of speakers
switched on at all times. An alternative is to permanently
connect a 150 ohm, 5 watt resistor across the tube amplifier's
output in parallel with the SVL-6. See (Figure 1) on next
page for hookup diagram.

"TECH TIP"

Wire size is

expressed by it's

AWG (American 

Wire Gauge) 

number. The lower

the AWG number,

the larger the wire,

i.e., 12 AWG wire is

physically larger

than 14 AWG.
