Polk Audio Omni A1 Wireless Amplifier: This amp will extend the useful life of your old speakers by allowing you to stream your music wirelessly and amplify it to your existing speaker setup. You can also use it as part of the Polk Omni Collection to control your music throughout each room of your home.
We bought a house with ceiling speakers in several rooms and purchased this to play internet music from the smart phone to those speakers. Works great with a speaker switchbox that we also purchased. We can play what we want to hear and control the volume, playback etc from the smart phone into any of the 4 rooms that had speakers wired in. We can add more wireless speakers at any time if we wish. Works great! This was a better choice than just buying a receiver and connecting it to the speakers.
