Russound A-K4

Simple and elegant, the A-K4 Amplified Keypad provides easy control of your music. Turn it on or off, select from up to six sources, or adjust the volume with just a touch - or use a remote control if you prefer.
As inconspicuous as a light switch, the A-K4 complements your decor. Its built-in amplifier powers your room speakers directly, or you can use its line outputs to feed an external amplifier or powered subwoofer.
The A-K4 works with any A-BUS hub or controller, as well as with A-BUS-ready receivers and A-BUS subzones on multiroom controllers.
