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 JR-S600


 Power Section
The JR-S600's output stage has an initial differential amplifier, followed by a second differential amplifier and a current-mirror Class-A predriver. The final stage is a Darlington-connected parallel pus-pull pure complementary OCL circuit. Included to safeguard the power transistors and your speakers from accidental damage is the self-restoring, patented JVC Triple Power Protection circuit.

Power Supply
Power regulation during high-amplitude musical passages is more efficient and powerful than in conventional supply systems with the use of a toroidal coil transformer to reduce distortion and crosstalk in the subsonics. Two huge 22,000µF capacitors deliver rated output without strain. What's more, mutual interference in the operation of the phono equalizer, S.E.A. and tuner circuits is avoided with the use of a constant-voltage ± dual power supply.

Phono Equalizer
Electronic FET switching for Phono 1 and 2 eliminates switching noise, while allowing direct connection of the phono equalizer circuit with the input terminals fro reduced hum noise. RIAA equalization ±0,5dB is excellent

FM and AM Highlights
A 4-gang frequency-linear tuning capacitor and a low-noise FET increase sensitivity and tuning precision. The high-inertia dual-flywheel design, a unique lateral-tune control and stretch-free "Radial Cord" cables in the tuning mechanism mean quick dependable operation.
A single-unit 4-resonator ceramic filter in combination with a 4-pole phase-linear LC filter permits flat group-delay characteristics to help achieve unprecedented selectivity in FM of 80dB without degrading other specifications.

Other FM/AM Features
High fidelity listening on FM, improved through Dolby processed noise reduction, can be enjoyed with the JR-S600 from JVC thanks to its built-in FM noise reduction system, requiring no adjustment. In the AM section, a high-integration IC with self-contained RF amp works in concert with a ceramic filter and low-pass filter to assure clear, pleasant AM sound.

Tape Dubbing
Record any source into either or both connected stereo tape decks with the convenience of monitor/playback controls foreach. With the Dubbing switch in you can copy a tape from either deck to the other.
