The compact disk player of G series which carries MASH and 1-bit DAC, and a digital servo. The nonlinear distortion of zero cross distortion etc. is not theoretically generated in a D-A-conversion part, but high MASH and 1-bit DAC of the play capacity of a minute signal are carried in it. High-quality sound-ization is attained especially by refining a circuitry further by SL-P900. First, the theoretical S/N ratio in an audio frequency band is improved by 20dB or more by making a clock frequency of operation twice over the past. Furthermore, since a PWM wave symmetrical with the upper and lower sides is outputted focusing on the PWM wave at the time of a zero output, there is no occurrence of a secondary higher harmonic theoretically also in the time of a large swing. Moreover, in SL-P900, it turns into one chip, this is carried, and 8DAC stream compositions which negate a higher harmonic by a differential circuit have realized a higher S/N ratio and low distortion, and the high linearity. The digital servo is adopted as a servo circuitry. In the digital servo, a Focus, tracking, and each amount of servoes of a traverse are controlled by software treatment for every disk to perform. While the servo property stabilized by this reduces the ripple of the fluctuation and the servo electric current in the time base of a digital signal and raises a tone quality, the play ability of a disk is raised. The measure against the extraneous vibration which affects play sound is strengthened, and the oscillation from a floor is sharply reduced by four insulators of the leg, and the optical deck insulator which consists of a spring and viscoelasticity material. Moreover, the influence of the aerial vibration by sound pressure is also suppressed by multilayer composite of the TNRC base with the outstanding periodic-damping property, and the metals chassis base. Furthermore, while arranging the disk tray made from TNRC in the good center of a weight balance, the silence operation is realized by employing a swing arm mechanism as a tray drive. The power transformer for exclusive use is carried in a digital signal/servo system, and an audio system at the power-source part, respectively, and the ill effect to the tone quality according RF components, such as a system-clock, to an included digital signal and a powerful servo electric current mostly is prevented. The optical digital output termination in which a soft mute and a level attenuation are also possible is carried. A fixture and two variable analog output are carried. Moreover, volume control by a remote control electric volume is possible for a variable output. Moreover, gilding is adopted as a lineout output or a headphone output. Class AA is adopted as a lineout circuitry and the faithful waveform transmission which cannot be easily influenced by a load variation is made possible. The high-quality sound part which repeated and selected the audition and the characteristic test carefully is used, and the carbon film resistor using a non-magnetic-material cap, and a high-quality sound electrolytic capacitor and the polypropylene capacitor for audios are adopted. The display mode functionality is carried and a display-device window can be switched off by remote control operation. If a key operation is performed at the time of putting out lights, the light will be switched on for 5 seconds.
