Authentic acoustic piano playability
With an 88-key piano action and synthetic ivory and ebony keys, the Graded Hammer 3 (GH3) keyboard reproduces the touch of an acoustic piano, from the heavy feel in the lower register to a lighter touch in the upper octaves. The GH3 features a three-sensor configuration that, accurately senses and interprets the behavior of the keyboard to provide a grand piano-style response and feel, allowing rapid note repetition and authentic expressive control.
This feature reproduces the slight change in sound at the instant you remove your fingers from the keys. What’s more, different key-off sounds are produced for staccato and legato playing.
When the hammer of a grand piano strikes its string, the other strings will also resonate. The YDP-S54 can reproduce this effect using its String Resonance feature.
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 case exhibit a phenomenon in which, if nothing is done, the volume of the sound will increase due to the resonant frequency of the material. However, installing Acoustic Optimizers with the same resonant frequency within the body of the piano suppresses this resonance. 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.
Intelligent Acoustic Control (IAC) – for comfortable practice at home
At low volumes, bass and treble used to be difficult to hear; however, YDP-S54 is equipped with Intelligent Acoustic Control (IAC) which adjusts the sound automatically, allowing players to enjoy balanced piano tones at any volume level.
