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.

Kenwood KR-6200 Receiver

FM/AM Stereo Receiver - a new masterpiece of stereo efficiency to carry on the Kenwood tradition of quality.

Kenwood unveils a deluxe new stereo receiver; the KR-6200 with sophisticated new circuitry for wide band response, low distortion, new NPN and PnP transistors for low-noise performance; new dual-protection circuit to prevent damage from power overload, excellent FM reception with exceptional sensitivity, selectivity and capture ratio, and a host of convenience features, including 2-system tape monitor, special midrange tone control, and linear FM dial scale

KR-6200 Features:
Frequency Linear Variable Capacitor - The dial scale has linear graduations (arranged at the same intervals) to make tuning easier
Front-end with 2 FET Circuits - The front-end contains FET circuits together with one dual gate element. These circuits assure high sensitivity, worthy of the name Kenwood.
1 IC and 3 Element mechanical Filter - The 3 element mechanical filter is employed in the IF stage. It improves the characteristics of capture ratio and selectivity
Independent AM and FM circuits for the IF Stage - The FM circuit for the IF stage is separated from the AM circuit. Such a scheme is effective in the reduction of mutual interference

Newly Developed DSD Circuit and MPX Circuit
The double switching system and the carrier leak block filter have been adopted. They are a great aid in improving the de-emphasis frequency characteristic and especially improvement of stereo separation.
Large Meters with Built-in Lighting mechanisms - The KR-6200 has two large-scale meters for tuning convenience
Protected Semi-Complementary Direct-Coupled Power Amplifier - The power amplifier is a protected semi-complementary direct coupled type which assures stabilized high performance
Equalizer Circuit with PNP can Type Transistor - This circuit  employs a PNP can type transistor for the improvement of s/n ratio and circuit reliability.
