SLK-100 Control (PZA)
Decora Style Screwless Rotary Knob with 100W Impedance In-Wall Volume Control
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.
In a basic multi-room system, only one speaker selector is used to connect the speakers to the amplifier/receiver. The speaker selector not only allows you to connect multiple speakers to the amplifier, but also adds internal impedance protection enabled by a manual protection switch. Our ISS and DSM series speaker selectors feature internal resistors that protect the amplifier. The disadvantage is that the normally 140 watt rated power is reduced by half when the protection switch is enabled, so it has a rated power of 70 watts with protection.
Characteristics
- Screwless Decora-style impedance-matching volume control for whole-home audio systems and dedicated audio zones
- Rated at 100 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
