An acoustic piano with volume control, or a digital piano with strings?
Yamaha’s latest development stretches the imagination and opens up a whole new world of possibilities.
Yamaha Transacoustic U1TA2
48″ 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 TA2 type TransAcoustic™.
The TransAcoustic™ Piano introduces a new way for piano players to emotionally connect with their instrument. The touch of the keys, the embodiment of sound, the resonance of strings; TransAcoustic Technology enhances the playing experience by using all elements of the acoustic piano to augment and amplify non-acoustic sounds. This means that any sound can be delivered through this naturally resonant piano.
A broad sonic palette
TransAcoustic™ TA2 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™ TA2 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.
Play-along to music
Enjoy playing along with any of the 50 preset songs that come with TransAcoustic™ TA2 type, accompanying your playing with songs you have recorded yourself, or even with commercially available songs played back through the sound board. You can play a duet with yourself, or you can just sit back and listen to the playback.
Featuring SILENT Piano™ SH2
Yamaha’s SILENT Piano™ SH2 technology allows practice sessions to be conducted with headphones. Yamaha’s SILENT Piano™ SH2 technology also features a superb binaural sample from the Yamaha CFX concert grand piano recorded using special techniques to perfectly capture the sound from the player’s natural listening position. These two technologies combine to create the perfect environment to play without disturbing others.
Connect wirelessly for Bluetooth® audio
You can stream audio files through TransAcoustic™ TA2 type by using a Bluetooth-enabled smart device. You can enjoy playing along with any songs on your smart device. (May not be available depending on your area)
Smart Pianist APP
The smart device app “Smart Pianist” (available as a free download) enables you to use the functions such as selecting Voices, controlling the metronome intuitively with the visualized interface, or display the score on your smart device.
The UD-WL01 USB Wireless LAN Adaptor (sold separately) is required to use Smart Pianist over a wireless connection.
Sophosticated & simple design of the control panel
The control unit has been given a sophisticated design that unobtrusively blends with the piano itself. Moreover, the simple controllers allow you to operate the instrument easily.
Real acoustic piano
Most importantly, a TransAcoustic™ piano is a wonderfully crafted acoustic piano produced in-house through Yamaha’s vertically integrated manufacturing process. This guarantees high-level playability, long lasting durability and a beautiful sound. When the hammers strike the strings, vibrations travel through the solid-wood soundboard creating a vibrant tone that will stimulate the senses.
Play piano at any volume
There are times when the full sound of an acoustic piano may not be appreciated by your family or neighbors. For these situations, simply activate the TransAcoustic™ function 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.
Enjoy different sounds
The TransAcoustic™ piano offers 19 pre-installed sounds, allowing you to select a voice that perfectly matches your music. Select from the award-winning Yamaha CFX Concert Grand, or from a number of electric pianos, organs, strings and much more! Additionally, you can connect any external sound source to be played back through the entire instrument.
No external speakers needed
With Yamaha’s TransAcoustic™ technology there’s no need to connect external loudspeakers. At its most basic level, TransAcoustic technology turns the piano into a ‘loudspeaker’ and the soundboard is working as the membrane for that loudspeaker. There’s no need to purchase extra speakers and cables. The piano is ready for you to play as soon as it’s delivered into your home.
3D Sound Projection
Sounds played through speakers can often sound one directional as they are coming from a single source point. In contrast, the Yamaha TransAcoustic™ system uses all acoustic elements of the piano to generate a larger and more natural omni-present sound. This technology makes the entire instrument a resonator, producing a rich and complex tone.
Natural string resonance
The TransAcoustic™ technology transmits the digital sound directly to the piano soundboard and makes the piano itself behave like a loudspeaker. The sound you hear has the natural tonal characteristics of the soundboard. The vibration of the soundboard is also transmitted to the piano strings and creates the same natural string resonance as when you play an acoustic piano. With the soundboard producing a rich tone and the strings a natural resonance effect, instrument voices sound better than ever. Digital was never more natural.
Combine acoustic and digital sound
Perhaps the most scintillating sounds are generated when you combine the acoustic and digital properties of the instrument – gentle orchestral strings under a natural piano, for example. You can also combine the CFX concert grand piano sample with the piano’s own acoustic sound to give it more power and depth. Can you imagine the sound and presence of a 9′ Concert Grand emanating from the footprint of a 48″ upright?
Play-along to music
Another way to enjoy TransAcoustic™ technology is to play the piano accompanied by pre-recorded tracks played through the soundboard. Because the instrument is a real, fully strung and resonant piano, the natural sympathetic vibrations of the soundboard, case and more significantly strings add a completely new dimension to performance. The sampled sounds come to life with a brilliant realism no other instrument can match. You can use the USB port to play back .WAV files or use the AUX-IN jack to connect an external music player.
Silent Piano SH included
The TransAcoustic™ Piano features Yamaha’s renowned SILENT Piano™ SH technology, so practice sessions can also be conducted with headphones. The binaural sampled CFX concert grand piano sample uses a dummy head recording technique to capture the sound from the player’s natural listening position. This offers the perfect environment to play without being disturbed or disturbing others. For all SILENT Piano benefits check our SILENT Piano™ web page.
