Equipped with a pitch control function.

The D/A converter is equipped with an 8fs18-bit D/A conversion system using a unique noise shaping technology.

The servo circuit is equipped with S Servo III.
In the S Servo III, the high-frequency noise component of the servo current is removed with a low-pass filter to supply a smooth servo current, which stabilizes the power supply from the power supply and prevents adverse effects on sound quality.

A digital CLV servo is installed in the drive system servo circuit that controls disk rotation.
The digital CLV servo detects the rotation of the spindle motor and controls it with 10-bit resolution to maintain an accurate linear velocity regardless of the disk's inner or outer circumference. It also detects the difference in inertial mass between the 12 cm CD and 8 cm CD disks to drive more appropriately.

Low noise and high stability are achieved by incorporating an RF amplifier in the pickup section.

The digital signal processing LSI uses the fourth generation LSI for the Sony CD player. Previously external RAM has been upgraded to a capacity of 32 kbit and built into the digital signal processing LSI. The precision of the signal processing capability is further enhanced by adopting the strict 6-fold error correction method.
