OSD Audio’s comprehensive line of Speaker Selectors allows you to gain complete control over your multi-zone audio system. With features like independent speaker and volume adjustability, dual input a/b source control, and impedance protection circuitry, you can easily custom tailor the sound in your particular application. A new and unique development in OSD’s Speaker Selector lineup is the ATM-7 remote controlled speaker selector. The ATM-7 allows you to remotely manipulate your speaker selector without having to be at the source. In addition to our tabletop speaker selectors, we also have in-wall distribution panels & a/b switches to choose from.
