Commentary
This CD player uses a turntable system and inherits the quality of the quality of high-end machines.
In order to suppress unnecessary vibration of the disk and to rotate it stably, a turntable system is adopted in the mechanism part.
By installing the pickup and spindle motor at the top of the disk, the entire disk can be supported from below, reducing unnecessary vibration caused by external vibration and disk warpage.
This reduces the deterioration of servo characteristics due to disk vibration and the influence of jitter on sound quality.
The D/A converter is equipped with a high-speed pulse flow D/A converter with built-in digital filter.
The Noise Shaper operates at a high oversampling frequency of 384 fs to provide a smoother output and reduces the noise floor due to requantization. This allows the use of a lower second order noise shaper to reduce the effect of out-of-band noise on sound quality.
In addition, by operating the master clock at a low frequency of 16.93 MHz, the effect of jitter is reduced.
Direct construction is adopted for pure signal transmission.
For this reason, a semi-center tray design is adopted, the pick-up mechanism is positioned almost in the center of the chassis, and the main circuit is laid out along the signal flow, connecting the pick-up to the output terminal with the shortest distance.
This reduces the penetration of external noise.
It is equipped with functions such as computer program edit, time fade edit, auto program edit, peak search, highlight scan, memory hold, delete play and reserve.
Equipped with a display off switch.
Equipped with CD-DECK synchro terminal.
Volume and headphone output can be controlled by remote control.
