Passive Audio, or line level Outdoor Volume controls are in actuality volume decreasers. One will set their stereo receiver or amplifier at the highest desired level, and the speaker volume control is as an in-line device used to decrease the audio output. When one has multiple units installed in various locations, it makes for a high performance but convenient audio speaker system.
So you are on the deck or by the pool and the phone rings. Do you want to go in the house to turn down the music? No way. Ahh, install an Outdoor Volume control and you can lower the volume from outside. Outdoor volume controls are virtually the same as indoor in wall models, but they either have a weatherproof /waterproof enclosure, or special gaskets to ensure water tightness, and hence high performance operation.
Wiring and installing these outdoor line level (and passive) controls is a simple 4 wire in (left + - & right + -) and 4 wire out . You would go from the speakers out on your amp or receiver to the input of the unit, and from the output to the speakers. With impedance matching models, you can connect from 2 to 16 pairs of speakers from one channel left/right output from the stereo. The impedance matching feature adjusts the impedance or resistance, measured in ohms, hence the stereo senses as if there is only one pair of speakers in use. You simply adjust a jumper switch for anywhere from 1 to 16 pairs of speakers.
Our line of these handy units is extensive, again, comprised of rotary knobs or slide switch. They are great for nearly every room in the house and are an inexpensive way to help operate your whole house audio system.
