The JVC
R-S33 is an AM FM stereo receiver FTC rated for 8 Ω at 27 watts RMS (per
channel, 20-20,000 Hz at 0,03% T.H.D.) one of the primary features is JVC's SEA
Graphic Equalizer, which provides ±12 dB equalization at five center
frequencies: 40; 250; 1,000; 5,000; 15,000 Hz. The SEA can also be programmed
to equalize the signal to the tape recorders.
One of two tape inputs is a "selected input" it could just as
easily be called an auxiliary input. The switching arrangement for this tape,
however, permits automatic dubbing to the second recorder. LED indicators are
used for a stereo beacon, left and right output power indicators, FM center
channel tuning, and Am FM signal
strength (AM tuning). The output power indicators have eight steps calibrated
for 0,03 to 40 watts into 8 ohms. The output power required to illuminate any
step was within ±10% of the indicated value. The frequency response of the
indicators was visually flat from 20 to 20,000 Hz. The FM center channel
indicator is what has become a more or less standard three-position indicator;
a green LED flanked by red LEDs, with center of channel. Except for the tuning
knob, all controls are the linear 9slider) type. An output hold-off prevents
power supply turn-on transients from being fed to the speakers.
Only JVC
gives you both Super-A amplification and graphic equalization. You'll hear
Super -A as pure, natural sound. Violins, cimbals, voices and other complex,
delicate sounds are smooth and airy. That's because Super-A does away with most
of the measurable switching and crossover distortion a source of harshness in
some conventional Class-AB receivers.
At the same
time, you'll get plenty of power. The R-S33 shown here gives you 30 watts per
channel minimum RMS into 8 ohms, from 20-20,000 Hz , with no more than 0,007%
Total Harmonic Distortion. A regular Class-A amplifier with this kind of power
would be heavy and expensive. But because it doesn't require high idling
currents, the R-S33 costs and weighs about the same as a conventional receiver.
Even the
most sophisticated amplifier can't correct cartridge peaks, speaker roll-off or
room acoustic. Neither can it accommodate your changing tastes in sound as you
take off Beethoven and put on disco. That's where JVC's 5-band SEA graphic
equalizer comes in. With independent controls at 40 Hz , 250 Hz , 1 kHz, 5 kHz
and 15 kHz, it lets you extend the deep bass without creating boominess. Mellow
out a voice without cutting the highs. Add brightness to the extreme highs and
more.
With all
this, the R-S33 has plenty of other features to recommend it; direct-coupling,
a sensitive tuner section with linear-phase IF filters, two tape monitors with
equalizer and dubbing facilities, LED power meters, and JVC's triple power
protection system.
