FM/AM Stereo Receiver from JVC
Features
Extra-Long tunning dial (240 mm ) for easier tuning and frequency linear in FM for faster station selection.
Double FM Muting
Tape Monitor Indicator
Internal AM Bar Aerial - AM sound is free fo noise, fuzz and whine.
50 Watts per channel, min. RMS (both channels driven into 8 ohms, 20-20,000 Hz, 0,03% T.H.D.)
Low-Noise Phono Equalizer with amazing 90 dB Signal-to-Noise Ratio
PLL Multiplex Demodulator in IC for Wide FM separation
Exceptionally High FM Signal-to-Noise Ratio bye newly developed IC
JVC's triple Power Protection
Two "P's" to remember - Power and Performance - for purer sound
Power and performance make this JVC model outstanding for its price. The JVC R-S7 delivers more power output for your money than any other in its class. Indeed, it drives even the most inefficient speakers with ease at low distortion of 0,03% or less. Control capabilities, looks, durably and circuitry add still more value.
Phono equalization is accurate with an impressive 90 dB Signal-to-Noise Ratio
Microelectronics have their place, but there's no ICs in this phono equalizer formed of discrete parts. No IC, for instance, can ensure the highs/n of 90 dB - higher than you'll find in many more expensive receivers.
Extra rugged Power Transistors for more.
The power amp of the R-S7 is a sophiosticated, fully complementary OCL type, with as many as twelve transistors in each channel. The power transistors themselves are extra rugged to provide true performance over a wide range of output. This means more musical margin.
Full safety is assured with JVC's triple Power Protection
This safeguards your system by providing three important functions;
1.Power On/Off shock noise never reaches speakers;
2.Speakers are electronically disconnected in the event an abnormal DC voltage appears at the terminals; speaker damage is entirely avoided; and
3.Power transistors are protected in the event of shorts, low speaker impedance or other power-related mishaps.
Tuner performance in FM and AM is as clean as we can make it.
The IF amps and a quadrature detector in the R-S7 are in IC from. Distortion is only 0,15% or less (mono), the Signal-to-Noise Ratio is an outstanding 82 dB, and the frequency response is 30 to 15,000 Hz. Then, for pinpoint tuning, a new 4-element ceramic filter raises selectivity to a high 65 dB. Another IC is found in the PLL (Phase-Locked Loop) FM stereo demodulator to keep distortion to a low 0,3% or less over long years of use. The AM sound is pleasant and listenable thanks to still another IC for AM RF/IF.
