What we think of the Yamaha YUS1TA silent upright piano

The YUS1 is a beautiful upgrade to the already class leading Yamaha U1, benefiting from upgraded hammer felt, strings and superior voicing. Add the latest TA2 generation of Yamaha's groundbreaking TransAcoustic technology to the mix and you have a seriously versatile instrument!

Yamaha's incredible TransAcoustic2 system allows you to not only play silently through headphones but also to use the pianos naturally resonant soundboard as a speaker. A digital sample of the Yamaha CFX and Bosendorfer Imperial concert grands is transmitted via specially configured transducers attached to the soundboard, vibrating the soundboard and bridges to reproduce the digital sound, effectively turning the large wooden soundboard into a speaker. You can turn down the volume, layer other sounds (of which there are 20!) on top of the acoustic piano for added ambience or plug in some headphones to practice privately - the choice is yours!

The Yamaha CFX sample has Yamaha's acclaimed Binaural Sampling giving an incredibly 'acoustic' sound through headphones, like the piano is in front of you rather than right in your ears. Virtual Resonance Modelling technology borrowed from Yamaha's Clavinova range of digital pianos brings an unprecedented level of natural resonance making the digital sound virtually indistinguishable from the real thing.

With Bluetooth for audio streaming and compatibility with Yamaha Smart Pianist app along with many others, the new TransAcoustic TA2 system is a versatile tool which combines the best features of a digital piano with the inimitable resonance and feel of an acoustic instrument.
