U Series
Yamaha U Series Upright Piano Spec Sheet
U Series Features
Precise, ultra-responsive touch, clear, full-bodied tone and a reputation for reliability have made U Series pianos the choice of professional musicians, conservatories, teachers, students and music lovers, the world over. Add to that, Yamaha’s legendary attention to every detail of every piano, and it’s no surprise that the U Series has been the world’s most popular upright for over half a century.
THE FINEST WOODS
The U Series soundboards and ribs are crafted from solid spruce that has been hand selected at our Kitami Mill in Hokkaido, Japan giving these pianos a richer, more resonant voice and evenly balanced timbre across the entire keyboard.
BACK POSTS, FORWARD THINKING
Years of cutting-edge research, including our proprietary wood-drying process, result in back posts that maintain their shape, strength and resonance for years to come
ADVANCED V-PRO FRAME
Yamaha was the first company to use an advanced Vacuum Shield Mold casting technology called V-Pro to create a stronger, lighter, more durable frame. Every U Series piano features a full-perimeter frame built to Yamaha’s exacting specifications at their Iwata Forge in Japan.
SPECIALLY DESIGNED HAMMERS
U Series hammers are crafted of the finest materials and painstakingly designed for each model to provide optimum tone, response and a lifetime of musical enjoyment.
SPECIALLY CRAFTED BASS STRINGS
Yamaha artisans in our factory in Kakegawa, Japan oversee the winding of pure copper and adjust the balance and tension of each bass string to the exacting standards and sound profile of every U Series piano.
WORLD’S FIRST ALUMINUM ACTION RAIL
Often copied but never equaled, the patented Yamaha aluminum action rail helps assure our piano keyboards are resistant to tiny fluctuations in humidity and temperature over time.
SOFT-CLOSE FALLBOARD
Inspired by our grand pianos, our damping mechanism prevents the fallboard from dropping abruptly, guarding against accidental injury or damage.
YUS Series Features
YUS Series pianos share many features from our Flagship CF Series pianos. From hand-wound German strings and concert quality hammer felt to meticulous voicing and regulation that brings out a range of colors more reminiscent of a grand piano than a traditional upright. It’s quite simply the grandest sounding upright available.
THE FINEST WOODS
The top ten percent of solid spruce from around the world is hand selected from our Kitami Mill in Hokkaido, Japan for the YUS piano soundboards. The crown is reinforced with full-length, solid spruce ribs for a refined, dynamic tone expected in a grand piano.
SUPERIOR VOICING AND REGULATION
YUS pianos are voiced and regulated by master technicians in Kakegawa, Japan to ensure that everything, from the strike of the hammers to the weight of the keys and depth of the key travel, are reminiscent of the finest grand piano.
HAND-WOUND BASS STRINGS
Yamaha artisans wind each bass string by hand to the exacting standards and sound profile of every YUS piano at our factory in Kakegawa, Japan.
CONCERT QUALITY HAMMER FELT
We took everything we learned from crafting the hammers of our flagship CFX concert grand and redesigned the hammers of the YUS to bring out powerful, nuanced tones on an upright piano
ROOM-FILLING SOUND
Each YUS piano features a proprietary Yamaha tone escapement system that helps provide the clarity of tone and power that is rarely found in an upright.
BACK POSTS, FORWARD THINKING
