The Stereophonic Optimizer—a new kind of headphone experience
When using headphones, the Stereophonic Optimizer lets players enjoy the dispersed sound heard when sitting in front of an acoustic piano. With the Stereophonic Optimizer, Voices sampled from acoustic pianos appear to come from the body of the instrument. This provides a comfortable, natural experience that removes the drawbacks of performing with headphones.
The speakers attached to the body exhibit a phenomenon in which, if nothing is done, the volume of the sound will increase due to the resonant frequency of the body. Conversely, installing pipes with the same resonant frequency within the body suppresses this resonance. Acoustic optimizers utilize this phenomenon.This improvement of the sound is something that has only been possible thanks to Yamaha‘s thorough knowledge of the internal acoustic characteristics of musical instruments.
For comfortable practice at home Intelligent Acoustic Control (IAC)
At low volumes, bass and treble used to be difficult to hear; however, YDP-S34 is equipped with Intelligent Acoustic Control (IAC), which adjusts the sound automatically, allowing players to enjoy balanced sound at any volume level.
