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.

Low-Mass Straight Tonearm with Dual Radial Bearings
A special alluminum alloy is used to give the arm its formidable strength and exceptionally low mass. Both qualities are needed to take full advantage of todays, supercompliant cartridges. The straight-line geometry assures the most accurate tracing angles as well as contributing to the arm's low mass. A pair of precision radial bearings give the arm a lateral sensitivity of only 10 milligrams. Even the normally-over-looked signal connectors are of the constant wipe type, insuring contact maintenance at all times.

Headshell
Thanks to the use of carbon fibres, the headshell is as light and rigid as the arm itself. It joins the arm with a semi-integrated plug-in system that utiliizes thick gold-plated wiping-type contacts. Oxygen-free copper leads are used to exclude electromagnetic influences (eddy-current losses) resulting in exceptional transmission characteristics. (Improved S/N ratio).

Skating Force Cancellation
Anti-skating is provided by a precision-calibrted adjustment to exactly match vertical tracking force.

Oil Damped Cueing
Feather-light contact between stylus and record groove is provided by the oil-damped cueing system. It is silent, smooth and, at the end of a record, completely automatic.
