Specialised Grand Piano Action
The AvantGrand N1 offers the player a specially-developed action that features the same configuration as that of a grand piano.. The hammers strike the “virtual strings” from underneath, allowing minute adjustments to the weight distribution of the hammers, and to the movement of the hammers themselves, for a smoother feel when playing. In addition to a hammer sensor, the AvantGrand employs a non-contact key sensor that has no effect on the movement of the keys, affording excellent recognition of the player’s pressure on the keyboard, timing, and the other delicate nuances that affect musical expression. This combination provides an impressive sensitivity for the entire range from pianissimo through to fortissimo, and the ability to translate even the swiftest trills of the pianist with transparency.
Spatial Acoustic Sampling, Spatial Acoustic Speaker System
With the introduction of AvantGrand, Yamaha took a revolutionary approach to sampling, recording and playback of the notes of an actual acoustic piano. Treating the soundboard not simply as a point source of sound but as a plane, we took samples at four positions, adding optimum centre and rear locations to the traditional left and right. As a sound source, we carefully selected the best single instrument from our CFIIIS full concert grand pianos for sampling. The end result of these efforts is that AvantGrand instruments recreate the original sound of a superb grand piano almost to perfection. Meanwhile, the AvantGrand speaker system has been designed to ensure that this sound is heard at its very best. A three-way system featuring woofer, mid-range and tweeter speakers reproduce the rich natural resonance of the soundboard accurately. Furthermore, each of the low, mid, and high-frequency ranges have been given their own amplifier to prevent interference between ranges. This innovative configuration allows the instrument’s outstanding sound system to reproduce the nuances of each individual note. For even greater sonic accuracy, speaker layouts have been optimised to the shape of the instrument.
