may not fit into the connectors. Never use solid-core, alu-
minum, or "Romex" type wire with the SVL-4AB. When run-
ning 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
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-4AB wiring
near electrical devices, route the speaker wires several feet
away from the electrical wiring.
Using the SVL-4AB with Tube-Type Amplifiers
Virtually all tube amplifiers must have a load connected at all
times. If one of the amplifiers to be connected to the SVL-4AB
is a tube amplifier, be sure to always have at least one pair of
speakers switched on at all times. An alternative is to perma-
nently connect a 150 ohm, 5 watt resistor across the tube
amplifier's output in parallel with the SVL-4AB. See
