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.

JVC 4VC-5244 turntable

This is the news that music lovers have been waiting for, now, they can play discrete 4-channel records on their home entertainment units. JVC, the developer of the world's first discrete 4-channel records, has found a home for them - two revolutionary discrete 4-channel record playback components. Whoever thought these beautiful sounds could be so easy, so economical, so convenient. JVC did. After all, JVC, developed the discrete 4-channel record in the first place. So it was just a matter of time before they came up with components capable of reproducing these magic record sounds.

Here are two revolutionary components that will be heard from for a long time - the 4VC-5244, a precision turntable with a built-in 4-channel demodulator, and the 4DD-5, a compact demodulator designed to be added to any existing 2-channel turntable and 4-channel reproducing system.


 Operation of the 4VC-5244 is in every way the same as a regular stereo record changer. The difference is the four signal cords which come from the rear panel. These signal cords carry the separate signals of the four discrete channels to a 4-channel amplifier.

The high quality record changer uses a 4-pole outer rotor induction motor driving a high inertia 11" die-cast platter at accurate speeds.

The cartridge was specially developed for the 4VC-5244 and uses the CD-4 Shibata stylus 4DT-35X giving a frequency response from 20 to 50,000 Hz.
