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 T-K100 tuner

 FM/AM Stereo Tuner
Though it lacks digital synthesizer tuning, the T-K100 is one of easiest to use tuners, and incorporates many new JVC tuner technologies; a low-noise J-FET transitor in the FM front end for high sensitivity and selectivity, and ICs wherever possible for better reliability. An extra-wide tuning dial, calibrated in linear units and softly illuminated units and softly illuminated, makes tuning easier.
Balanced AM mixer to reduce harmonic and intermodulation distortion.
