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.

Pioneer PA-5000 (1978)

Static-balanced S-shaped universal tonearm with extra light aluminum alloy pipe and magnesium alloy headshell. Special alloy avoids partial resonance caused by bends in the arm pipe which often cause distortion in less well designed S-shaped arms. Gimbaled support system provides high sensitivity and arm height adjustment lever calls upon special Helicoid system for fine height change of +/- 3mm. Newly developed antiskating system applies lateral pressure directly without affecting sensitivity.

The PA-5000 features a unique counterweight incorporating several precision engineered parts, which damps both stylus and tone arm resonance. When moved by stylus vibrations, due to warped or uncentered records a 50 g "dynamic absorber" weight inside the counterweight applies a "brake". The weight is supported inside by means of a spring and several concentric rubber washers, called a Bellows damper. It is coupled to the tone arm vis stainless steel stranded wires.
