CD SECTION
•Adjustment
Since this CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be combined freely.
Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.
Items adjusted automatically
(1)Offset adjustment (The offset voltage between the head amplifier output and the VREF reference voltage is compensated inside the IC.)
*Focus offset adjustment
*Tracking offset adjustment
(2)Tracking balance adjustment (waveform drawing 14-3 EFBL)
(3)Gain adjustment (The gain is compensated inside the IC so that the loop gain at the gain crossover frequency will be 0dB.)
*Focus gain adjustment
*Tracking gain adjustment

EXPLANATION OF DOLBY SURROUND PRO LOGIC AND EVALUATION METHOD
Outline
•Namely, two speakers are connected in parallel to one amplifier.
•In the Pro Logic BYPASS mode the amplifier for C-ch (center channel) and the amplifier for S-ch (surround channel) are in MUTE state. The SP output is cut.
•In the normal mode of Pro Logic ON mode the amplifiers for C-ch and S-ch are in operative state, so that the SP output appears.
•In the Phantom mode of Pro Logic ON mode the amplifier for C-ch is in MUTE state, so that the SP output is cut. The amplifier for S-ch (surround) is in operative state, so that the SP output appears
•State of element output and terminal output in specific mode

NOTES ON SCHEMATIC DIAGRAM
•Resistor:
To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type.
•Capacitor:
To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type
(P.P.): Polypropylene type
•Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.
•The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given.
1.In the tuner section, ( ) indicates AM
< > indicates FM stereo
2.In the main section, a tape is being played back.
3.In the deck section, a tape is being played back. ( ) indicates the record state.
4.In the power section, a tape is being played back.
5.In the CD section, the CD is stopped.
•Parts marked with “ ” ( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
