Monoprice 139067 SS-Pro 12 Speaker Selector - Dual Source, 300W

The Monoprice SS-Pro 12 Speaker Selector is designed for audio enthusiasts and installers who need to distribute sound from up to two sources across as many as 12 separate speaker zones. Whether you're wiring a multi-room residential setup or outfitting a commercial space with distributed background music, the SS-Pro 12 provides a centralized control point with individual zone switching via front panel push-buttons. The dual-source A/B switch on the front panel makes it easy to toggle between two connected amplifiers or receivers without re-cabling.

At the heart of the SS-Pro 12 are its audiophile-grade impedance-matching transformers, which ensure safe power distribution across all connected speaker pairs. This is critical because running multiple speakers in parallel can drop impedance to dangerous levels for amplifiers — the SS-Pro 12's rear-panel rotary switches let you dial in the correct impedance setting for each zone. Rated at 300 watts peak per channel and equipped with removable snap-in connectors for clean wiring, this selector is built for reliability in permanent installations where consistent audio distribution matters.
