The Quick Silent System
The MP51 is a high-quality traditional acoustic piano with a special feature, the Quick Silent system, which allows you to play silently, any time, without disturbing the neighbors or other people in your household. The center pedal engages a hammer shank stopper, which prevents the hammers from hitting the strings, and effectively silences the piano. Sophisticated digital electronics then take over, reproducing the same rich tones electronically through stereo headphones.
4-point optical fiber key sensors
The 4-point optical fiber key sensors "read" your playing, and accurately transmit it to a built-in electronic piano tone module.
Real concert grand in stereo
Digital sounds are produced by stereo sampling of the top-of-the-line Yamaha CFIIIS concert grand piano. The digital tones are rich and expressive, with full dynamic and expressive range, and up to 32-note stereo polyphony. Reverberation effects are available to give you the feeling of playing in a variety of different spaces, resulting in a "live" room inside your headphones. You can connect the piano to audio equipment using the AUX terminals on the back of the control box.
Produced by one of the world's leading piano manufacturers
This piano is of the highest quality-designed for high sound quality with reliability and attention to detail built in at every stage. YAMAHA has the rare combination of advanced optical fiber sensor technology, extensive experience with digital pianos and keyboard, and a long tradition of acoustic excellence in piano design.
Seasoned for Destination
Yamaha specifically seasons this piano for the U.S. market. The tuning stability, finish and overall musical integrity are enhanced over the long life expected of a fine piano.
Permanent Crown Solid Soundboard
Yamaha utilizes a process that creates a permanent crown in the soundboard and at the same time minimizes soundboard cracking. The customer can feel confident that not only will the piano last for years, but the beautiful sound of a Yamaha piano will last a lifetime.
Solid Spruce Soundboard
At the Yamaha lumber mill and wood processing facility, the finest spruce is quarter sawn; and less than 10% of the total is selected and reserved for Yamaha piano soundboards. Solid spruce, rather than laminated spruce or poplar, is the choice in all fine pianos for the amplification of sound, best tone and sustain.
Full Length Ribs
Yamaha reinforces the crown in its soundboards by using ribs that continue to the edge of the soundboard, and are glued into the notched liner (or inner rim on the grand piano). Reinforcing the crown ensures that the tone quality will remain for years and years and improves tuning stability.
Yamaha uses V-PRo (Vacuum Shield Mold Process) in casting the iron frame (plate). V-Pro plates are stronger and visually more appealing. Critical dimensions are produced more accurately than before.
Extruded Aluminum Action Rails
Yamaha engineering developed a unique Extruded Aluminum Alloy Action Rail (bearing a Yamaha patent) that is one of the best innovations for improving a piano action in the last 100 years. The usual fluctuations in wood rails that effect touch, caused by periodic weather changes, are eliminated allowing stable, long-lasting action regulation.
Each key of a Yamaha piano is individually tested and measured for the corrections needed to obtain uniform "down weight" pressure. Yamaha actions play correctly and uniformly. This balancing helps ensure a lifetime of superior touch and control across the keyboard.
Uniform Key Travel
Yamaha designs all grand and vertical pianos to have the same key travel. Regardless of size, type or model of Yamaha piano, the keyboards will always feel the same.
Yamaha uses SPRUCE for the keys on all models of pianos. Spruce is very light and possesses a very high ratio of strength to weight. It is ideal for key construction, even though its cost is greater than either sugar pine or bass wood. Yamaha keyboards respond quickly, providing fast repetition for the most intricate piece of music. Yamaha keyboards withstand heavy use over years of fortissimo passages.
Yamaha Servicebond™ Assurance Program
This program is a service that is provided to the customer, without additional charge, 3-8 months after delivery of their piano. This service is a thorough check up and adjustment procedure to "rejuvenate" a piano after initial play-in and acclimation of the piano to its new environment. It takes the form of a "service policy" that assures the piano wil start its life in the home correctly, and after six months or so of settling and becoming acclimatized, will receive the benefit of a service visit to return it to the conditions specified by the manufacturer.
