The ARIUS YDP-105 offers luxurious tone and expressiveness that remain true to the basics of an acoustic piano, with stereo-sampled Voices such as a Yamaha grand piano delivered through newly designed speakers. Its weighted 88-key GHS (Graded Hammer Standard) keyboard reproduces the touch of an acoustic piano, from a naturally heavy feel in the lower range to a lighter touch in the upper octaves, with half-damper pedal control. Damper Resonance reproduces the broad, deep sound field of an acoustic piano. Includes 10 Voices (grand piano, electric piano, organ, vibraphone, strings and more), 10 built-in classical songs and compatibility with the free Smart Pianist app. Includes PA-150 power adapter and BC-108B bench (per price list).
