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.
