Get to know this product.

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 multi-room controllers.

  • Uncomplicated control of basic audio functions
  • Passes IR commands to connected source equipment
  • Variable line-level output allows connection to an external amplifier or powered subwoofer
  • Controllable by an A-BUS system remote
