Yamaha U30A อัพไรท์เปียโนมือสอง

Yamaha  U30A is a improvement version of Yamaha’s U3 upright piano series. These instruments deliver the highest quality of touch and tone that one would expect from a top of the range Yamaha. This particular piano has a tremendously balanced tone and would be ideal for an advanced player looking for a piano of the finest quality, or a beginning student looking to invest in a piano that will carry them through to Grade 8 and beyond.The U30A upright pianos have long been a leading choice for educational institutions, professionals, musicians and discriminating home pianists. Now, thanks to comprehensive redesign, substantial refinements in materials, construction, production processes and overall design.

The updated Yamaha U series acoustic upright pianos, all offer a longer music rack, and improved back assembly. The U30A  piano has a new floating soundboard support system .

The floating soundboard support system is based on Yamaha grand piano design and allows the soundboard to vibrate more freely, thus improving the depth and characteristic of bass and mid-range tones. Like the preceding U series, the new uprights feature Spruce soundboards, full-length ribs, the exclusive Yamaha V-Pro plate, extruded aluminium alloy action rails and uniform key travel with spruce keys and balanced action.

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 best 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.

V-Pro Plate
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.

Metal 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.

Balanced Action
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.

Spruce Keys
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.
