Ultra realistic piano sound and feel meets portability.
The Yamaha P-155B Digital Piano offers professional quality sound with Yamaha's legendary piano touch. Whether you're practicing at home or away, performing solo or in a band you now have top-shelf Yamaha digital piano technologies at your fingertips. The P-155B digital piano has advanced sampling methods and the ultra-expressive Graded Hammer (GH) keyboard so you don't have to choose between portability and piano quality.
Hand-crafted Pianos, High-quality Voices
To ensure the finest grand piano sound for the P-155B, Yamaha went straight to the source: Yamaha's finest 9-foot concert grand, a hand-picked CFIIIS. Next, a master piano technician painstakingly tuned and regulated the CFIIIS to sonic perfection. Then they applied their Pure CF Sampling technology to accurately capture every aspect of the CFIIIS sound, keeping post-processing to an absolute minimum to maintain sonic integrity throughout. The result is a truly authentic grand piano sound with powerful, dynamic bass, warm mid-range, and crystal-clear highs.
Layer upon Layer
Using Yamaha's Dynamic Stereo Sampling (DSS) technology, the incredibly natural 4-level piano sample is a breakthrough achievement for digital pianos. It means that, depending on how hard you strike a note, you will hear one of four piano recordings on each and every key for an unprecedented level of dynamic range and tonal expression. Playing softly doesn't simply lower the volume; it produces the quiet recordings of piano notes. And likewise, playing more forcefully triggers separate samples at different levels.
Ascension to Detail
If you close your eyes while playing a grand piano, you'll find its sound is a bit more complicated than note-on, note-off. Yamaha has gone to great lengths to capture these sonic artifacts in the P-155B. Their meticulous efforts include recording a felt damper coming to rest on a vibrating string when a note is released (Key Off Samples), or reproducing the sound of the open strings that wash over your performance when using the damper pedal (Stereo Sustain Samples and Damper Resonance).
A Touch Above
When you look inside the lid of a grand piano you'll see different-sized strings which require different-sized hammers with require different weights. The keyboard of the P-155B utilizes Yamaha's GH (Graded Hammer) technology to reproduce the true feel of a grand piano keyboard action, with heavier touch in the lower keys, lighter touch in the higher keys, and subtle gradations of weight and response throughout. Thanks to the input of concert-level, professional pianists during its development, the GH keyboard features superb balance and remarkable consistency. Performing or practicing on a GH keyboard properly develops and maintains an artist's technique for making the transition between P-155B and an acoustic grand.
Perfection Made Practical
As a full-featured digital piano, the P-155B gives you all you need for practice, playing, and performance. It has an internal high-power, two-channel (12W + 12W) amplifier with high-performance speakers built in. This lets you and your audience hear the authentic sounds in their full glory.
