CD player with optical transmission system.

A photo coupler is used for transmission between digital and analog by optical transmission method, and digital noise is prevented from flowing into the analog circuit by separating the digital and analog signals.
An output-in-phase transformer is added to the output stage to prevent digital noise from flowing into the amplifier.

The mechanism body uses an outsert compound molded product with a large damping effect, and an isolated floating suspension (I ・ F ・ S) structure that is separated from the chassis and suspended with spring and non-resilient rubber.

In order to sharply cut the high-frequency components centered on the sampling frequency of 44.1 kHz, a digital filter with double oversampling is adopted. The sampling frequency is doubled to 88.2 kHz, reducing the influence on the audio band.
In addition, it is equipped with a 16-bit ladder type D/A converter, which eliminates the analog crystal oscillator needed for the integration type, thus suppressing the generation of beats and improving the reliability of the circuit.

A 3-beam laser pickup has been adopted, and the tracing ability has been improved by light weight and compactness and anti-vibration measures.

It is equipped with functions such as 16-track random memory which displays addition / subtraction of memory time, UP/DOWN direct selection function, fast forward / rewind function, repeat function, etc.

The 8-digit display shows the track number, next track number / memory channel number, and minutes / seconds of wrap time / remaining time.

A 10-key remote control is included.
