PX-870
A NEW DESIGN AND SOUND AUTHENTICITY ROLLED INTO ONE
The Sound Projection feature in the ultra-compact PX-870's powerful speaker system guarantees multi-dimensional natural sound emission and an unparalleled sound experience.
Colour variations
The nuanced simulation of damper and string resonances on the PX-870 produces a realistic grand piano experience, with numerous other tones to complete the package. The keyboard also includes impressive features such as lid position simulator, volume sync EQ, headphone mode EQ and audio recording function. The Concert Play function also allows the pianist to practise and play the piano part with an orchestral accompaniment.
