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.

Sansui SR-3030 BC

 A completely professional two-speed turntable incorporating many of the exclusive features of Sansui SR-4040BC, including the direct belt-drive system and unique anti-howling insulators. Compare its performance figures with those of the SR-4040BC. You'll see that they are minor, and more than offset by the savings this precision component offers. One of the larger differences between the two is the SR-3030BC's unique  Inside Force Canceller, a weight device that opposes the tonearm's natural tendency to cut inward.
This mechanism cheks this tendency for more accurate tracking. The SR-3030BC is an ideal component for use in any medium to large stereo system.
