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 through the speakers. If you must locate the SPS-4 wiring near electrical devices, route the speaker wires several feet away from the electrical wiring.

Using the SPS-4 with Tube-Type Amplifiers

Virtually all tube amplifiers must have a load connected at all times. If the amplifier to be connected to the SPS-4 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 SPS-4. See (Figure 1) on next page for hookup diagram.
