8x Pair High Power Single Source Speaker Selector with Impedance Protection and Easy Input/Output Connectors - ISS8

<p>The ISS4, ISS6 and ISS8 are low-profile speaker distribution systems with individual on/off selectors for each listening zone which distribute one stereo speaker-level signal to eight, six or four stereo listening zones. The ISS Series also provides manual power protection that is activated from the rear panel.<p>The manual power protection switch engages 10 ohm /15 watt resistors wired in parallel, three per channel in the ISS8 or two per channel in the ISS6/ISS4 providing higher power handling capability than the competition (able to handle up to 50% more power!) in order to protect your amplifier. All ISS’s are capable of handling 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.

300W Impedance Matching Screwless Slide Volume Control, Decora Style Wall Plate Snap On, White (Bone, Almond, Black, and Brown available) - SLS-300

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.
