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.

Nikko NP-390 turntable

NP-390 Auto-Return Turntable features:

Belt-drive platter drive mechanism for silent operation

4-pole synchronous motor for smooth, uniform torque

Large 30 cm (12-inch) die-cast aluminum platter

Statically-balanced tonearm

Operation convenience

 

The NP-390 provides excellent value for your investment, and in its price range, feature-for-feature, it has little or no competition. Unit features automatic return, meaning as you move the tonearm to the adge of the platter, the platter begins to rotate; turntable then handles the rest, including the return of the arm at the end of play automatically. Silent operation is provided by the belt-drive platter drive mechanism.

Superlative performance is assured by a 4-pole synchronous motor, large die-cast aluminum platter, statically-balanced tonearm with direct readout tracking force control and anti-skate control. The result are audible: wow and flutter and signal-to-noise ratio.
