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.

Sony PS-3300 turntable

Sony unveils the PS-3300, a $200 direct-drive turntable that's semi-automatic. So the contest between our PS-3300 and their vaunted PL-510 is really no contest. Because in the crassest terms, we give you more ;an automatic arm return and a reject button. And that's a substantial difference, for no difference in price. What's more, we didn't shave anything to make it possible.

 

The PS-3300 has a finely crafted direct drive system with a brushless and slotless DC servo-controlled motor.

The PS-3300 innovates with a speed monitoring system that state troopers would love to get their hands on; an electronic process using an 8-pole megnetic pick-up head and a pulse coated platter rim. Plus there's independent fine speed adjustments, a tonearm that's so sensitive it's almost neurotic, and so on.

And to see the attention to detail that Sony stands for, note what the PS-3300 stands on. Bell-shaped rubber feet that are specially constructed to prevent both acoustic and mechanical feedback (When it comes to feedback, we put our feet down)

They absorb vibrations - whether from footsteps bouncing on the floor or sound waves bouncing off the wall. Otherwise, these vibrations would be transferred to the stylus, amplified, and be transffered back to the stylus - creating a vicious cycle.

If you're wondering how we managed to do this - how our semi-automatic shot down their high-flying manual - our response is a brief one.

Sony relied on its engineers.
