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.

Optonica RP-5200 turntable

Optonica RP-5200 Double Direct Drive Stereo Turntable


With its direct drive tonearm motor, the RP-5200 has greatly anhanced tonearm trakking accuracy, while the direct drive DC turntable motor assures extra-steady platter rotation. The direct drive tonearm system floats the tonearm over a record and then gently lets it down on the record at the touch of a control switch. For extra protection, the solenoid will immediately lift the tonearm from the record if any malfunction occurs. With soft-touch controls plus a microprocessor to offer computer accurate control of all turntable features, instant response to all commands is ensured. A statically-balanced straight tonearm provides just the right stylus pressure and trackability. A convenient repeat key allows you to listen to arecord again without having the tonearm return to the resting position.
