The decoded sound tracks from the blu-ray disk and the elements of audio that are downloaded or streamed through internet or either internally generated by the blu-ray player are decoded in the form of Pulse code modulation digital signals.

In order to lighten the circuitry, the compression ratio was limited to one-third (1/3), and a differential pulse code modulation (DPCM)(*2) scheme featuring simple structures was adopted.

Other features include its Dynamic Acoustics technology, which allows the piano to replicate the direct sounds of hammers striking string, delivering the reflective and resonating sounds of an acoustic piano performance, and its Pulse Code Modulation, which includes settings for grand, upright and electric piano and also features the tones of a harpsichord, pipe organ and strings.
