Yamaha TransAcoustic U-Series U1 TA3 Upright Acoustic Piano - 48" Satin American Walnut

The soundboard is your amplifier
When a hammer strikes a string, all elements of the acoustic piano resonate together to amplify the unique sound of the instrument. TransAcoustic Technology uses these acoustic elements to bring digital sounds to life, allowing you to adjust the volume and experience the piano in a whole new way.

Let there be light transducers
Transacoustic's state-of-the-art, ultra-light transducer turns digital sounds into vibrations and applies them directly to the soundboard. All without sacrificing the remarkable acoustic tone you’ve come to expect from a Yamaha piano.

Every nuance, every note
An advanced non-contact Articulation Sensor System continuously measures the movement, timing, depth and force of every key attack and release to faithfully capture and reproduce the subtle nuances of your performance.

Pure, natural sound
Three proprietary technologies work together to emulate the natural feeling and sound of an acoustic piano in your headphones. Virtual Resonance Modeling (VRM) recreates the resonance of the strings, soundboard and case. An advanced binaural sampling method simulates the sound you hear when sitting at the piano. Smooth Release Technology models the subtle interactions of the piano strings with the damper.

Find your voice
The world-renowned Yamaha CFX and Bösendorfer Imperial concert grands are two of many digital voices available in your headphones including electric pianos, harpsichords, organs, strings, choir and synth pad.

Plays well with others
It’s easy to connect TransAcoustic with your audio and MIDI devices for recording, live sound or broadcast and it works seamlessly with computers, mixing boards and Bluetooth®-enabled devices.

The finest woods

The U Series soundboards and ribs are crafted from solid spruce that has been hand selected at the 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 a 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 exacting specifications at the 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 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.

The world's first aluminum action rail

Often copied but never equaled, the patented Yamaha aluminum action rail helps assure these piano keyboards are resistant to tiny fluctuations in humidity and temperature over time.

Soft-Close Fallboard

Inspired by Yamaha grand pianos, a damping mechanism prevents the fallboard from dropping abruptly, guarding against accidental injury or damage.
