Yamaha U1TA2 PE Polished Black Upright Piano

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.

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™ 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.

You can play TransAcoustic™ TA2 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 colors, from sparkling high notes to powerful bass tones. The legendary Bösendorfer, meanwhile, is renowned for its sonorous and rich Viennese sound.

Yamaha’s advanced binaural sampling technology uses samples from the CFX, Yamaha’s acclaimed concert grand piano, recorded with specialized microphones that capture locational information and other nuances discerned by the human ear. The resulting sound is so natural, so enveloping, that you’ll soon forget you’re even wearing headphones at all.

In a grand piano, sound resonates throughout the body of the instrument, producing a rich reverberation that envelops the listener in sound. This phenomena is reproduced perfectly through enhanced Virtual Resonance Modeling (VRM). The original VRM calculates the various states of the strings for each of the 88 notes on the keyboard, from one instant to the next, and timing and depth of damper pedals pressed. The enhanced VRM now also calculates aliquot resonance in the upper octaves, and the full resonance of the soundboard, rim, and frame. This technology allows for vivid, bright, richly-varied expression that reflects the limitless number of factors inherent in piano performance.

Featuring Yamaha's Smooth Release technology, TransAcoustic™ TA2 type offers the crisp tone heard when playing staccato as well as the lingering sound produced by releasing the keys more. This provides finely-nuanced response to the pianist’s playing.

Under each of the 88 keys is a Yamaha-unique continuous-detection grey-scale shutter key sensor. These sensors detect the movement of the keys continually, allowing natural musical expression even when the piano is in TransAcoustic™ mode or SILENT Piano™ mode. Since they do not come into contact with the keys, these sensors do not affect the feel of the keyboard in any way.

Grand piano with TransAcoustic™ TA2 type are fitted with hammer sensors that allow even slow keystrokes or rapid trills. To ensure that they do not affect the feel of the keyboard in any way, Yamaha uses non-contact sensors.

Grand piano with TransAcoustic™ TA2 type features a quick escape system that allows the sound muting mechanism to be fitted to a grand piano without sacrificing any of the playability or musical expression demanded of such instruments in an acoustic performance. This system allows optimal separation to be obtained between the hammers and strings by adjusting the distance between the hammers and strings, ensuring that the feel of the keyboard stays in the best possible condition whether playing acoustically or with the sound muted.

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)

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.

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.

The headphones that come with TransAcoustic™ TA2 type are designed in a way that minimizes the strain on users after long hours of playing. This newly employed headphones contribute to the improvement of sound quality as well as to the reduction of fatigue during performance.
