Operating Principle of
MULTI MUSIC SCANNER
(Automatic program selection facility)
This is basically identical with the RC-343/646's MULTI
MUSIC SCANNER (MMS) facility. The only difference is
the use of the newly developed AN6260 IC which enables
skipping of more programs.
Features
1) It is possible to skip up to 8 programs.
2) Used together with the PAUSE button, it is possibleto
skip 9 to 16 programs.
3) If the number of programsto be skipped is not set,the
next program will be automatically selected.
AN6260
I) This IIL logic LSI incorporates a dynamic LED drive
matrix.
2) When the AN6260 is operating, the output signal is
muted becauseotherwise noise would be developed due
to dynamic drive of LEDs.

Asterisked parts show "NEW PARTS". Other parts
are all "CURRENT PARTS"; therefore, check your
inventory and order situation before placing new order
to avoid making extra stock.
The circuit board assemblies and whole assembly of
cassette mechanism in this model will not be available
as spare parts.
The partsmarked A arethe important partsfor safety
assurance.
Use the specified part, when replacing the safety assur-
ance part, never use an equivalent one.

The facility should operate with a reduced voltage of 6.5 V at
the end of tape during PLAY/REC, FF, and REW.
During REC, a load the sameas that of the amplifier is applied.
Lock PAUSE, PLAY , and FF (REW) buttons and apply 6.5 V
instantly to the solenoid after the tape is wound. PAUSE and
FF (REW) buttons should be released in this order. The motor
should be supplied with 6.5 V.
During PAUSE in PLAY or REC mode, PAUSE button
should be released when 6.5 V is applied to the solenoid. The
motor should be supplied with 6.5 V.

I) Stand the mechanism upright with the motor sidefacing
downward. Set it in the PLAY mode. Pull the projected
part of the pinch roller arm slowly with a tension gauge.
The gauge should read 350 — 500 grams when the pinch
roller just stops to rotate.
2) If the gauge reading is outside the given range, replace
the pinch roller spring or adjust by bending it.
• If the pressure is too great, the pinch roller bearing may
generate noise. Wow & flutter may be caused when the
pressure is too great or weak.

Torque Torque
Adjust in the following sequence.
(j) Head azimuth
Connect an oscilloscope to the LINE OUT jacks. Using
test tape VT T-658 (10 kHz, -15 dB), adjust so the phase
difference between the L and R outputs is 00 and
maximize the output level at the sarne tirne.
@ Tapespeed
Connect a frequency counter to the LINE OUT jacks.
Playing back test tape VTT656 (3,000 Hz), adjust the semi-
fixed resistor in the motor so that the frequency counter
reads 3D10 Hz.
@ Playbacklevel
Connect an electronic voltmeter to the LINE OUT jacks.
Playing back test tape VTT664 (l kHz. 16 rnM), adjust
VR302 and VR402 so that the L and R output levels
@ Recordingcurrent
Apply 1 kHz (-24 dBs) to the LINE IN jacks. Cut off
bias. Adjust VR303 and VR403 so that current of 30 gA
(0.3 mV/IO ohms) flows through the head. Then adjust
VR305 and VR405 so that the VU meter reads O dB.
@ Biasfrequency
Connect a frequency counter acrossTP301 and 302. Adjust
L501 so that the counter reads 66 kHz.
@ Biascurrent
METAL: Connect an electronic voltmeter across TP301 and
302 (TP401 and TP402). Adjust VR301 and VR401 so that
the voltmeter reads6 mV/IO ohms (600 g,A).
NORMAL: Adjust VR304 and VR404 so that the volt-
meter reads2.8 mV/IO ohms (280 gA).

1. Fast forward torque
Fit a torque gauge to the take-up reel disk and put the
mechanism in the fast forward state. The gauge reading
should be 100 — 160 g.cm.
1) If the torque is outside the given range because of
insufficient pressure Of the FF idler against the flywheel
or unstable operation of the FF idler freewheel
mechanism, bend part O of the fast forward button
lever in direction A or move the FF idler clutch spring
plate up and in the direction of @ .
2) If the torque is not correct even When the FF idler
freewheel mechanism operates properly, move the FF
idler clutch spring plate in the direction of @.
2. Rewind torque
Fit a torque gauge to the rewind reel disk and put the
mechanism into the rewind mode. The gaugereading should
be 100 — 160 g.cm.
1) If the torque is outside the given range because of in-
sufficient pressure of the FF idler against the flywheel
or unstable operation of the FF idler freewheel mecha-
nism, bend part (D of the rewind button lever in the
direction of B or rnove the FF idler clutch spring plate
up and in the direction Of(j)
2) If the torque is not correct even when the FF idler free-
wheel mechanism operates properly, move the FF idler
clutch spring plate in the direction of @ .
Note: The torque may be incorrect if the rubber parts (the
belt and idlers and the circumference of the fly-
wheel) are not clean. If they are dirty, clean them
with alcohol.

C. Separation Alignment
A. 19 kHz Alignment (regular Method)
I. Connect a frequency counter to the test point TP5.
2. Adjust the variableresistor R31 sothat the frequency
becomes 19 kHz ±250 Hz.
B. 19 kHz Alignment (Simplified Method)
1. Tune to a FM stereo broadcast.
2. Set •the variable resistor R31 to the center position of
the range in where the stereo indicator keeps lighting.

Turn the dial drum fully counterclockwise (to the lowest
frequency).
Use Kevlar cord (1,910 mm long and 0.5 mm in dia-
meter).
Install the string in the sequence of the numbers.
Align the needle holder (disk) with the white circle mark
on the MMS LED Circuit Board.
Needle holder
Hook the spring to a suitable
hole so that it is expanded by
about 3 cm.
