Yamaha U1 TA3 TransAcoustic Upright Piano


A perennial favorite among discerning pianists, the Yamaha U1 offers outstanding musical performance, setting the standards by which many other upright pianos are measured. TransAcoustic™ functionality has been added to this U1. This is a TA3 type TransAcoustic™.


TransAcoustic™ technology


Newly developed TransAcoustic™ technology transmits digital sound directly to the piano soundboard, thus making the piano itself behave as a speaker. On a TransAcoustic™ piano, the sound that you hear is resonating directly from the soundboard. The tone generator sends an optimized audio signal to transducers that are connected by a coil to the soundboard. This sets the coils in motion, causing the soundboard to vibrate and generate sonic vibrations that travel through bridges attached to the soundboard, and are ultimately transmitted to the strings, making them resonate with sound.


Play piano at any volume


There are times when the full sound of an acoustic piano may not be appreciated by your family or neighbours. For these situations, simply activate the TransAcoustic™ mode and the hammers will no longer strike the strings. Non-contact sensors under each individual key detect your keystroke depth, velocity and timing and send this information to the tone generator. Just adjust the volume and hear the digital sound of your piano performance coming from the entire instrument. Naturally, there is no need for headphones or external amplification.


Two World-Renowned Piano Sounds


You can play TransAcoustic™ TA3 type with the voices of CFX, Yamaha’s finest concert grand piano, and Bösendorfer’s legendary Imperial. All 88 keys are sampled individually. As Yamaha’s flagship grand piano, the majestic CFX boasts a wide palette of tonal colours, from sparkling high notes to powerful bass tones. The legendary Bösendorfer, meanwhile, is renowned for its sonorous and rich Viennese sound.


A broad sonic palette


TransAcoustic™ TA3 type offers total 20 pre-installed sounds such as electric pianos, harpsichord, organs, strings, choir, and synth pad, allowing you to select the ideal voice to match your preferred musical genre.


Combine acoustic and digital sound


Thanks to their unique construction, TransAcoustic™ TA3 type allow you to layer the natural, resonant sound of the acoustic piano together with voices from the tone generator. Perhaps the most scintillating sounds are created by combining the acoustic and digital properties of the instrument—for example, gentle orchestral strings seemingly played from an acoustic piano—to achieve sonic textures with a natural quality not found on any other instrument.
