The FM broadcast signal waveform from the antenna is fed to the two dual- gate MOS field-effect transistors in the front end for radio frequency amplification. This signal is converted into an intermediate frequency by the dual- gate MOS FET mixer stage in combination with the signal from the local oscil- lator. 2. The intermediate frequency signal , con- verted within the front end , is fed to four ceramic filters and three ICs , where it is tuned , amplified , and detected , becoming a audio frequency (composite) signal. The composite signal following detection is fed to the 4 CH MPX terminal jack and the multiplex decoder stage. 3. The multiplex decoder stage uses one IC for three functions: to demodulate the composite signal into the left and right stereo signals , channel to operate the automatic mode switching between stereo/mono , and to switch the stereo indicator lamp appropriately. The decoding system uses a phase locked loop (PLL) circuit , which assures continuous stable operation and excellent stereo sepa- ration with low susceptibility noise (such as car ignition to external noise) and ambient temperature changes. After decoding, the signal is fed to four transistors and one LC filter , where the residual carrier component (38kHz , 19kHz and SCA) is rejected , and then to the audio amplifier section. 4. The FM muting circuit consists effectively of two circuits , designed to reduce the pulse noise which can so easily arise when a muting circuit is operative. The one circuit is an electronic switch incorporated into the IC , so that the de- modulated circuit is switched off and on in the IC , and the other short- circuits the audio signal by means of a reed relay. 5. The AM tuner section employs one mono- lithic IC which functions as radio frequency amplifier , frequency converter , local oscillator , intermediate frequency amplifier , and detector. The output is a pure audio signal. 6. The signals which are applied to the MIC and PHONO terminal jacks are selected by the FUNCTION switch before being fed to the first stage of the three- stage differential direct- coupled equalizer amplifier by which the signals are amplified. In order to reduce the switch noise , the circuit configuration employed enables the potential at the input and output terminals to be set at near zero volts. 7. The output from the equalizer amplifier together with that from the AUX terminal jacks , the audio signal from the AM tuner and the audio signal from the FM tuner , are all selected by the FUNCTION switch , and pass through the switch circuits for TAPE DUPLICATE , TAPE MONITOR , 4 CH ADAPTOR DOLBY NR ADAPTOR , and the circuits for BALANCE and VOLUME controls , before being fed to the control amplifier. 8. The control amplifier has an extremely high input impedance , sistors in a using PNP and NPN trandirect-coupled two- stage circuit. This greatly reduces the influence of the performance inherent in equipment connected externally. The output from this two- stage direct- coupled circuit is divided into two circuit systems. One goes to the TONE switch via the twin tone control circuit , and the other goes directly and unmodified in any way .to the TONE switch. The TONE switch selects between them. 9. The amplifier section of the twin control has closed loop NFB amplifiers for both the main and sub circuits , each of which has its own transistor , eliminating mutual interference. 10. The control amplifier output is fed to the power amplifier after passing through the LOW FILTER , HIGH FILTER and AUDIO MUTING circuits. The first stage of the power amplifier is a differential amplifier element with constant current load , and the second stage , too , uses a differential amplifier element , so that DC potential drift is prevented. On the other hand , the final output stage uses two power transistors in parallel in both the upper and lower circuits , so that large collector dissipation is possible. Again , in order to reduce the distortion which occurs at low signal levels , the idle current has been set at a standard level of 100mA. 11. The power amplifier output is fed to the three push buttons which form the SPEAKER switch. This selects A , B , and C speaker system terminal connection. If all three speaker systems were to the effective connected simultaneously, speaker impedance might be less than 4il. To guard against this possibility, when all three buttons are depressed together , all three systems are disconnected from the amplifier. 12. The power amplifier circuit board includes a power limiter circuit which is independent circuit. If the power transistor of the signal current exceeds the maximum rated value the power limiter circuit shorts the input signal to protect the power transistors. The ' sensing ' for this protective circuit is performed by detecting the voltage drop across the emitter resistors of the power transistors. There are also protective circuit which guard against DC potentials at the power amplifier output junctions , against speaker complex load impedances less than , and shorts across the speaker terminals. Their operation is such that , under the corresponding abnormal condition , a relay acts to separate the output junction and the Further , these protective output circuit. circuits also help to mute DIAL CORD STRINGING 1. Turn the tuning capacitor so that its plates protrude as much as possible. 2. Tie one end of the string to the spring on the TUNING pulley (attached to the tuning capacitor ). 3. Lead the string around pulley A , then wind it three turns around the TUNING shaft. 4. Lead the string around pulleys B , C and D then wind it 1- 1/2 turns around the TUNING pulley. 5. Now tie the other end of the string to the spring on the TUNING pulley. Turn the TUNING shaft and check for proper function. Then trim the ends of the string. 6. Turn the TUNING shaft until the plates of the variable are all the way in. Move the pointer to the left-end starting point on the dial and fasten the unwanted signal which immediately follows switching the POWER switch ON , and to immediately disconnect the output after switched OFF. it to the string in that position.
