Indoor Volume Controls

Impedance vs. non-Impedance Volume Control

In a carefully planned impedance matching scheme, you can turn the protection switch off thereby ensuring you get the most from your amp. Our impedance matching volume control is for a non-impedance application. Just leave the jumper to the default setting which is 1/2X. The resister based volume control produces a better bass response. Use these volume controls with multi-channel amp and impedance matching speaker selectors.

60W Impedance Matching Rotary Style Volume Control Kit with (White, Bone and Ivory) Decora® Plates - SVC-60

Rated at 60 Watts peak, this unit is built with close attention to performance, reliability and durability. Some folks prefer the knob control over the slider type which is why we offer both. As you can see by the many reviews, the result is a blend of transparency and functionality, with low distortion and ruler flat frequency response. Like all our SVC Kits the SVC60 comes with White, Bone or Ivory Decora® inserts, outer plates, control knobs.

100W Impedance Matching Screwless Slide Volume Control, Decora Style Wall Plate Snap On in White (Bone, Almond, Black, and Brown available) - SLS-100

All speakers have an impedance rating, typically 8 ohm 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 incoming load. To operate safely and consistently, the amp needs to see an 8 ohm load, and that’s where speaker selectors and impedance-matching volume controls come into play.

300W In-Wall Impedance Matching Volume Control Rotary Knob with On/ Off Switch - SVC205

The SVC205 is a Self-Impedance Matching Volume Controller with an on/off switch. Volume controls do not add gain (volume) to your speakers; they simply attenuate the volume up or down. During setup, you'll set the source volume to its optimum level, then the volume control turns the sound down to almost inaudible levels. The SVC205 let's you turn sound off completely.
