Sony PS-4750


The Sony PS-4750 uses the new material SBMC (Sony Bulk Mould Compound) in the construction of it's turntable platter and cabinet.

Together with the use of servo-controlled direct drive DC motor, this new material with its unique acoustic and vibration absorption properties provides an excellent signal to noise ratio.

An innovative frequency sensing device is utilized in the stereo control system in the form of a magnetic coating inside the platter.

This unusual frequency generator (FG) component of the servo system, contributes substantially to the exceptionally low degree of wow and flutter.

Newly engineered rubber insulation mats isolate externally caused mechanical vibrations that would have an adverse effect on the quality of reproduction.

The high compliance, low friction tonearm is provided with a precisely engineered anti-skating compensator for proper tracking and superb reproduction throughout the audio spectrum.

Other features of the PS-4750 include a high-visibility stroboscope, a built-in stylus overhang checker, a cueing lever to prevent record and stylus damage, and convenient pitch controls for accurate tone reproduction.
