Stereophonic Optimiser: a new kind of headphone experience
Unique to Yamaha, the Stereophonic Optimiser adjusts the spacing of the sound and the separation from the piano when listening via headphones, resulting in a spacious sound image that will inspire you to play for hours at a time.
Intelligent Acoustic Control (IAC)
At low volumes, bass and treble used to be difficult to hear, however, YDP-S52 is equipped with Intelligent Acoustic Control (IAC), which adjusts the sound automatically, allowing players to enjoy balanced sound at any volume level.
The body of the YDP-S52 contains Acoustic Optimisers that regulate the flow of sound and control tone. A new technology developed from Yamaha’s intimate knowledge of the acoustic properties of musical instruments, Acoustic Optimisers deliver a natural, smooth sound across the entire keyboard.
