With Echo Link Amp and an Echo device, you can create voice-controlled music groups throughout your home and play streaming music wherever your system goes—the whole house, in one room, or outside. Or plug in a stereo component—like an amplified turntable, CD player, or MP3 player—and cast music to multiple Echo speakers at once. You can also stream high-fidelity music on your headphones.
Echo Link Amp easily connects to your speakers—bookshelf, tower, in-wall, in-ceiling, or outdoor. The inputs and outputs provide compatibility with your existing audio equipment, so you can play music from your favorite source on the system you already love—and it's designed to fit in an audio rack.
