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 SVL-1 wiring near electrical devices, route the speaker wires several feet away from the electrical wiring.
