Sony PS-X800

Direct Drive Turntable with Linear Tracking Tonearm

Description

Features of the Sony PS-X800 include:

Unique servo controlled linear tracking tonearm designed to duplicate the movement of the head which cuts the record master Compared with a pivoted arm, a linear tracking arm has a very small tracking error which means greatly reduced harmonic distortion, improved tracking ability and channel separation.

The horizontal and vertical movement of the tonearm are monitored by Sony's Biotracer sensors, and this information is transmitted to the tonearm by linear motors to suppress resonance at low frequencies and to obtain the maximum signal to noise ratio.

The tonearm balance and stylus force are electronically controlled by adjusting current to the linear motor for vertical movement.

The PS-X800 is a fully automatic system with feather-touch controls. Record size is automatically set by a photo sensor, a muting system is activated when the tonearm is lifted and speed and direction of tonearm movement are easily controlled with the arm direction and fast buttons.

The unit is powered by Sony's linear torque BSL motor with speed governed by a very stable quartz oscillator and magnetic speed monitoring system.

The PS-X800's cabinet is made from a special inorganic (non-plastic) moulded compound with low 'Q' and newly developed resilient feet, effectively minimizing outside vibrations and acoustic feedback.

Review

In some respects the PS-X800 was quite a good turntable, with the present arm probably the weakest link. In truth however the performance was little better than the less costly PS-X600 - £375 HiFi Choice 1983
