Though closely modelled on Yamaha’s immensely popular U1, the YUS1 is refined in a number of ways, and which sets it apart in terms of tonal quality and overall appearance. Unlike the U1, for instance, the YUS1 uses premium hammer felt, being the same as that used in Yamaha’s flagship CFX Concert Grand.
The result of this is a sound which has a far wider dynamic range than the U1, with greater power, depth, and a wider range of tonal colours throughout the compass of the instrument. In addition to this, the bass strings are wound with copper by hand rather than machine (as with the U1), so the bass is far more resonant and rounded in character. The cabinet is also finished by hand, and so the casework boasts a higher level of elegance and refinement when compared to that of the U1.
TA2 TransAcoustic System
This model incorporates the up-to-date SH2 Silent System, meaning that you can practice without disturbing others, by using headphones. However, you may be tired of using headphones all the time, whenever you wish to practice, for instance late at night. With the TA2 TransAcoustic system you have full volume control over the piano without the need for headphones! How does it do that?
By utilizing two transducers which are strategically attached to the soundboard, it is possible to transmit the digital sound that would normally coming through the headphones through the natural wood of the soundboard itself, thus effectively using the soundboard as an amplifier. This means that you’re benefiting from the highly resonant qualities of the spruce wood whilst also being able to turn the volume up and down in the usual way. You can also play all the other voices (e.g. strings, organ, electric pianos), and similarly hear them all come from the piano itself.
In addition to this, even though the strings are not being struck in this mode, they are still resonating in sympathy with the vibrations of the soundboard (whenever the right pedal is being used), which further enriches the sound. You can even play audio files through the piano from your smart device via Bluetooth. Lastly the compatible Smart Pianist app gives you even more control over the instrument by allowing you, for example, to change the sound in terms of different venue reverberations, transpose, tuning and so on.
