Russound P75

Russound's factory refurbished P75 amplifier can save you a little dough when you're outfitting a custom-installed home audio system. This amp is backed by the manufacturer's full one-year warranty. And it's got some specialized features designed to make your multi-room, multi-source audio system easy to use.

Your primary source gets priority — meaning, anytime the amp senses a signal coming from that primary source, it'll switch to it automatically. The amplifier switches back to your secondary source automatically after there's no longer any signal coming from the primary source. This clever automatic switching setup means you won't need to manually switch inputs. Say you have a Sonos Connect hooked up as your primary source.
