U1 TA2 TransAcoustic Yamaha Studio Upright Piano

Yamaha U1 TA2

48" TransAcoustic™ Upright Piano

Newly developed TransAcoustic™ technology transmits digital sound directly to the piano's soundboard - transforming the piano itself into a speaker. Play the piano at any volume with TransAcoustic™ Mode. In this mode, the system sends a digital sound to the piano's soundboard instead of having the hammers strike the strings. Now, you can enjoy the rich, warm overtones of an acoustic piano at volumes no acoustic piano can reach - without headphones! Need a louder sound? Activate TransAcoustic™ Mode and the system will amplify your playing - using the piano itself as a loudspeaker. No PA needed!

Even better, you can connect your smart device and play along with your favorite bands, activate SILENT Piano™ Mode and play through headphones or connect to your piano with the Smart Pianist app and control everything wirelessly! Yamaha's TransAcoustic™ technology gives your piano nearly unlimited potential.

The new TransAcoustic™ U1 Yamaha piano incorporates all of the traditional acoustic features that made the U1 an industry icon, with state-of-the-art digital technologies that further enhance the instrument's range, projection and versatility. Ideal for practice rooms, classrooms, studios and homes, the TransAcoustic™ U1 Yamaha piano unlocks a musician's complete potential.

Riverton Piano Company is the only Yamaha dealership in the Phoenix metro area selected to host your TransAcoustic™ experience. Come in today and see how much more your piano can do!
