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.
O POWER ON
When the machine is turned on, the built-in microcomputer is initiatized (Fig. 4-1) and is ready to re'

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.

4.4 DIRECT MUSIC SEARCH
For direct search,the tape is first rewound completely in RE\{ mode. \ryith one of the search keys depressed, the tape is then fast-forwarded to the beginning of the program desired (the intervals between programs are counted during FF mode).
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.

the following examples.
Ex. 1 When there are 2 effectiue digits (any digit apart from 0), such as 560 ohm
and 47h ohm (tolerance is shown by J = 1Vo,and K = 1OVo).

r Before commencingany electricaladjustments,make
surethe followingchecked/completed.
1. All mechanical adjustments must have been
completed.
2. The headsmust be clean and demagnetized.
3. Connect a 50kA (47kSl
52kO) dummy
resistanceto the OUTPUT terminal with OdB
:1V during level measurements.
4. Use the specified tapes for each adjustment.
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.

12. 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. For the latest
information,alwaysconsultthe current PIONEERService
