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 TA2 type TransAcoustic™.

Yamaha’s TransAcoustic™ range is a new breed of piano which at its most basic level turns the soundboard into a loudspeaker, meaning any sound can be delivered through this naturally resonant piano component.  The Yamaha TransAcoustic U1TA2 Upright Piano is a fantastic acoustic piano in its own right, as well as boasting near perfect digital piano replication with Yamaha’s SILENT Piano™ system. This combination of both the acoustic and digital, in addition to the usual Yamaha build quality makes the U1TA2 attractive as a long term, practical investment for a lifetime.

Featuring Yamaha CFX and Bösendorfer Imperial concert grand samples, VRM Virtual Resonance Modelling and Smart Pianist App compatibility for intuitive control via your smart device.

This U1 upright piano is 100% Made in Japan, and is certified pre-delivery by an authorised YASA tuner.

What is TransAcoustic™ technology?

Yamaha have focused on the acoustic piano’s essential mechanism of resonating sounds. When you press the piano keys, its hammer strikes the corresponding strings, and the strings vibrate. The initial sound is small, but the soundboard amplifies it with the entire body of the piano serving as a resonator. The result: the distinctly rich sound of an acoustic piano. TransAcoustic™ technology deftly employs this mechanism of resonance keyed by the soundboard.

Creating acoustic sound from digital audio sources

TransAcoustic™ technology does not rely on speaker units to produce sound; instead, transducers are used. Transducers convert audio source signals into vibrations, and then relay them to the soundboard. The soundboard amplifies the vibrations, and the entire piano vibrates sympathetically. Even digital audio sources go through the same mechanism of resonance, so that the sound that reaches your ears is as rich as that of an acoustic piano.

Specially designed transducers for acoustic pianos

Commonly used transducers are too heavy to install on soundboards since the transducer weight compromises the soundboard’s essential functions. In response, Yamaha developed transducers specifically for acoustic pianos, designing them such that only the lightweight vibrating parts are installed on the soundboard. This allows faithful reproduction of the sound of an acoustic piano.
