CIRCUIT DESCRIPTIONS 4.1 CONTROL PART This model carries out all of its controls by the use of a microcomputer (IC 501). Modes and progtams are selected by the key input supplied into the key matrix circuit (Fig. 4-4), while the microcomputer controls various sections such as mechanism drive, circuit switch'over, and mute control circuits by feeding command outputs into those circuits' The display circuit is provided to indicate the music program being selectedand REC, DOLBY NR, etc' being turned on or off.

Fig.4-l I 4.2 KEY MATRIX CIRCUIT The key matrix circuit, composed as in Fig. 4-4, sends scan pulse to control the mode input for decks A and B as well as program selection input. The scan pulse decodes outputs from pins L4,75, and 16 on the microcomputer, sending 10 m sec pulse from pins 1 through 5 of IC 502as shown in Fig.4-2. This pulse, in turn, is fed into one of the pins 17 through 22 of.IC 501 as the key matrix input corresponding to the key input, thus allowing the microcomputer to send output signals matched with key inputs to each section.

When the beginning of the wanted program is reached, the tape is set in the STANDBY mode. Depressing the PLAY key allows the program to start. In this way, the desired progxam is automatically located for playback by depressingthe program No. key. The direct music search mode allows desired programs to be played back in a desired sequence regardless of the order in which the proglams lvere originally recorded (for the first program to be played back, tape is rewound until the beginning of the tape is reached; from the second progmm onward, direct search takes place). Moreover, the sarne prograrn can be played back as many times as the prognm No. key is repeatedly depressed(up to 16 times). When used for copying, this mode enables the desired number of progxams on the original tape to be dubbed in any desired sequence. During copying, the non-recordedsectionsbetween the programs being dubbed are automatically adjusted for a uniform interval (automatic random editing). 4.5 MODE CHANGE IN THE MECHANICAL SECTION The mode selection for the mechanical section is controlled by the output (pins 37 through 40) from the microcomputer (IC 501) corresponding to the key input. The output from the microcomputer turns on and off SOL 1 and SOL 2 of the mechanical section, which trigger mode changes with the po\Mer assist mechanism using the rotar5l power of the capstan motor. The mechanical section changes its mode as shown in the Fig. 4-13, and this always via the stop mode. The timing chart in Fig. 4-15 shows the control signals for different modes sent from the microcomputer. .

Although test tapes have both A and B sides, only use side A where the label is attached. STD-331B: Playbackadjustment STD-608A: NORMAL blank tape STD-603: CrOz blank tape STD-610: METAL blank tape 5. Prepare the following measuring equipment. AC millivoltmeter, audio generator,attenuator, oscilloscope. 6. Adjust both left and right channels unless otherwise specified. 7. And unless indicated otherwise, leave the DOLBY NR switch in the OFF position. 8. Let the set warm up for at least a few minutes before commencing adjustments. And before commencing the record/playback frequency response adjustment, let the set "age" for three to five minutes. 9. Always adjust the set in the given adjustments order. If the order is changed, proper adjustment will not be possible, and this may result in loss of performance. Adjustment Procedure DeckA 1. Head azimuth adjustment 2. Playback equalizer adjustment 3.

SAFETY INFORMATION 1. SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.l by connectinga leakagecurrenr tester such as Simpson Model 22*2 or equivalentbetween the earth ground and all exposedmetal parts of the appliance (input/output terminals,screwheads. metal overlays, control shaft,ètc.l. Plugthe AC line cord of the appliance directly into a 120V AC 6()Hz outlet and turn the AC power switch on. Any current measuredmust not exceed 0.SmA. Reading should not be above 0.5mA 2-wire cord Also test with plug reversed (Usin9 AC adapter plug as required) AC Leakaç Test ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A PG TENTIAL SHOCK HAZARD AND MUST BE COR. RECTED BEFORE RETURilING THE APPLIATTCE TO THE CUSTOMER. 2. PRODUCTSAFETY NOTICE Many electricaland mechanicalparts in the appliance have specialsafety related characteristics.Theseare often not evident from visual inspectionnor the protection afforded by them necesarily can be obtained by using replacementcomponents rated for voltage, wattage, etc. Replacementparts wtrich have thesespecialsafely characteristicsare identifiedin this ServiceManual. Electricalcomponentshavingsuchfeaturesare identified by marking with a À on the schematicsand on the parts list in this ServiceManual. The use of a substitute replacementcomponent wttich dose not have the same safetv characteristicsas the PIONEER recommendedreplacementone, shonrnin the parts list in this ServiceManual,may createshock, fire, or other hazards. Product Safety is continuously under review and new instructionsare issuedfrom time to time.
