With the Yamaha RX-D485, you can create a home cinema with wireless speakers. Use WiFi to connect the 5.1 AV receiver to the Yamaha MusicCast 20 or MusicCast 50 wireless speakers. By connecting the speakers to the receiver using WiFi, you won't be bothered by cables, so you can neatly hide the wireless speakers. The acoustics of your room will sound just like those in the movie theater, thanks to the Cinema DSP 3D technology. This technology simulates the sounds of well-known theaters and cinemas. Combined with the included YPAO measuring microphone, the receiver adjusts the sound to fit the acoustics of the room. This means the sound is optimized for your listening position.
