Panasonic SL-PS840

Commentary

A CD-player that uses virtual battery operation, advanced Mash and 1-bit DAC.

Virtual battery operation is used for the power supply.
This power supply circuit was developed by taking full advantage of the characteristics of MOS-FET, and achieves high sound quality by eliminating noise from power supply and digital circuit.

In order to reduce the adverse effect of external vibration on sound quality, newly developed THPB vibration isolation design is adopted.
In this structure, external vibration is cut by an effective combination of steel plate and viscoelastic body.

The D/A -bit DAC is used for the D/A converter. Mash
The 8 DAC differential circuit eliminates noise components and realizes high S/N, low distortion factor, and high linearity. The differential circuit employs an instrumentation circuit configuration that is used as a measuring instrument in order to pursue high-precision and high-fidelity reproduction.

Digital servo is adopted.
This circuit minimizes the current flow by adjusting the servo amount to an appropriate and stable amount according to the CD condition and reduces the ripple of the servo current.

The loading mechanism is equipped with SL1.
The disk tray is made of TNRC with excellent vibration damping characteristics, and the unique swing arm drive system realizes smooth operation.

Class AA circuit is used for the line-out circuit to realize faithful waveform transmission that is not affected by load.

A high-quality carbon film resistor with a non-magnetic cap is used for the resistor, and electrolytic capacitors and polypropylene capacitors for audio use are used to improve sound quality.

Digital optical output terminal is mounted.

The line output terminal is gold-plated.

Equipped with a display mode function that can turn off the display display, reducing FL display noise.

Wireless remote control is included.
