The Perfect Match - The Biotracer Tonearm and Tangential Tracking
The PS-X800 is designed for audiophiles and music lovers who will settle for nothing but the very best reproduction of music from their record collection. Careful attention was given to each detail of the PS-X800 to make it the new standard against which every other turntable will have to be measured.
Outstanding Features:
Tangential Biotracer tonearm for minimum distortion, excellent soni performance
Biotracer tonearm elicits the best performance from the widest variety of cartridges
Biotracer actively damps tonearm/cartridge resonance and achieves wide stereo separation
Biotracer controls tracking force, anti-skating and tonearm automatic functions
Tonearm
Advanced fully automatic operation is silent and responsive for total convenience
Automatic zero-balance for fast interchange of cartridges
Tonearm may be "indexed" left and right at high or low speed without lifting dust cover.
Feather-touch controls respond to the slightest finger contact for fast, effortless function selection
Automatic record-size selector permits precise and safe indexing
Audio muting circuit provides silence during start, return, and cueing phases
Luminous end-of-disc sensor frees the tonearm from mechanical linkages for improved reliability
Capable of operation in synchronization with selected Sony cassette decks using the optional Sony RM-65
Repeat mode for continuous music
Accepts universal headshells and cartridge/headshell combinations
Turntable
Quartz lock with Magnedisc servo control prevents even minute speed variations caused by external factors
The Sony Linear Torque BSL motor designed for uniform and smooth delivery
Of torque
Electromagnetic braking provides rapid and smooth half of platter rotation
Sony Bulk Molding Compound base is both rigid and acoustically inert to reduce feedback
Adjustable, gel-filled feet isolate turntable from external vibrations
The tangential Biotracer tonearm
The Sony PS-X800 is the first turntable to combine the advantages of tangetial tracking with the low-frequency performance of a stable tonearm foundation. Like other straight-line tracking turntables, the X800 uses a tonearm mounted on a moving platform. However, unlike any other tangetial arm in the world, the tonearm of the X800 incorporates Sony's innovative Biotracer design.
The Biotracer's automated Motional Feedback (MFB) system constantly senses and corrects for tonearm vibration. For this reason, the arm provides all the advantages of a solid foundation: full-bodied, detailed low frequencies. And you get the reduced distortion, and improved stereo separation associated with tangential tonearms.
the Biotracer tonearm of the PS-X800 is the first design to fulfill the promise of straight-line tracking. Quite clearly, the combination of the Biotracer tonearm and the tangential configuaration results in a joyful musical experiance.
Uni-Motion design for superior precision
He tangential Biotracer arm provides still more benefits. Other straight-line tracking arms require some slight tracking error to keep the arm moving forward. These tonearms are in a constant state of correcting tracking error. In contrast, the PS-X800 incorporates Uni-Motion design. Uni-Motion brings the tonearm slowly towards the center of the record, even when no tracking error is detected. As a result, the tangetntial Biotracer maintains superior groove tangency. Phase differences between the stereo channels are dramatically reduced. This results in a stable stereo image, with outstanding spatial characteristics.
As a final measure of precision, the vertical tonearm bearings, so important to tonearm function, are made to extremely close dimensional tolerances. Situated in Sony's long-span pivot, they provide the final assurance of exquisite performance.
The PS-X800, with its Biotracer tonearm and straight-line tracking displays exceptionally lower distortion, extraordinary stereo separation and greatly improved reproduction of the inner grooves of all records, most important, the Biotracer tonearm is unique in providing the solid, vibration-free tonearm base necessary for superior music reproduction.
