What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Extraordinary Performance with the Biotracer Tonearm

All of the performance and convenience features of the automatic-lift PS-X500 complement the Biotracer tonearm incorporated in both of these remarkable components.

 


The conception of the Biotracer tonearm represents a sharp departure from conventional wisdom. The common approach to tonearm dsign involves eleborate, separate mechanisms that deal individually with stylus force, skating force and tonearm/cartridge resonance. In contrast, the Biotracer tonearm in the PS-X500 deals with all of these functions in an integrated, unified fashion. There is no manually adjustable anti-skating control, no mechanical linkages for cueing, automatic indexing or automatic shut-off.

PS-X500 features manual operation with automatic tonearm lift and motor-shut-off at end of play
