HEOS Link

HEOS wireless pre-amplifier: turn any stereo system into a wireless zone.

With the HEOS Link, you can add HEOS multi-room audio to an existing music or home theater audio system, and you can play different songs in different rooms or the same song in every room. Control your Denon receiver, integrated amplifier or mini system right from the HEOS app.
