Now you can combine your favorite Decora light switch with screwless volume control. All speakers have an impedance rating, typically 8 ohms for a pair of home speakers. To operate in the safest mode, most standard amplifiers and basic two-channel receivers are rated for an 8-ohm input load. To operate safely and consistently, the amplifier needs to see an 8-ohm load, and that's where speaker selectors and impedance-matching volume controls come into play.

• Screwless Decora-style impedance-matching volume control for whole-home audio systems and dedicated audio zones
• Rated at 300 watts per channel with minimal bass roll-off
• The impedance matching feature stabilizes the ohm load so that parallel connections of multiple volume controls can be installed without damaging the amplifier.
• Front-mounted adjustable jumpers allow easy adjustment when connecting multiple pairs of speakers to a single receiver or amplifier.
• Accepts wiring up to 14 gauge and fits in a standard electrical box with a depth of 2.9"
• Precision electronics provide low distortion and a rule-flat frequency response
• 12-step linear rotary-style knob for a wide range of listening volumes
