Environmental factors play an important role in the sonic signature of a room, and with any type of audio. Yamaha’s own YPAO™ automatic calibration technique, refined over decades of use in Home Theater products, has been optimized for the R-N1000A to deliver the ideal listening environment, as if you were in a professional audio listening room - without requiring any laborious manual setting adjustments. YPAO™ features precision EQ, which performs exceptionally high-precision equalization with accuracy of up to 192 kHz / 64-bit audio resolution. YPAO™ R.S.C. (Reflected Sound Control) works in tandem to actively control the important early reflection sounds, automatically adjusting and optimizing how the sound is heard in your room, depending on the materials of the walls and the speaker placement. Which means you can enjoy the profound sound and immersive feeling unique to Hi-Fi audio - right in your own living room.
