Connecting the AC power lead
Check the setting of the AC voltage selector located on the rear panel before plugging the unit into an AC socket. If nec- essary, adjust the selector to correspond to the AC power voltage used in your area. Selector adjustment: Turn the selector with a screwdriver until the appropriate voltage number appears in the window (110V, 127V, 220V or 230V - 240V AC). Notes:
Plug the AC power lead into an AC socket, after any con- nections. Unplug the AC power lead from the AC socket if the unit will not be in use for a prolonged period of time.
AC Plug Adaptor In areas (or countries) where an AC socket as shown in illustration is used, connect the unit using the AC plug adaptor supplied with the unit, as illustrated. The AC plug adaptor is not included in areas where the AC wall socket and AC power plug can be directly connected (see illustra- tion ).
AM/FM interval (span)
The International Telecommunication Union (ITU) has established that member countries should maintain either a 10 kHz or a 9 kHz interval between broadcasting frequen- cies of any AM station. The illustration shows the 9 kHz interval zones (regions 1 and 3), and the 10 kHz interval zone (region 2). Before using the unit, set the SPAN SELECTOR switch (on the rear panel) to AM tuning interval (span) of your area. To change the tuning zone:
1
Press the ON/STAND-BY button to enter the stand- by mode.
2
Set the SPAN SELECTOR switch to "50/9" for 9 kHz AM interval (50 kHz FM interval), and "100/10" for 10 kHz AM interval (100 kHz FM interval).

Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacingthepickup.Therefore,differentPWBsandpickups
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.

EXPLANATION OF DOLBY SURROUND PRO LOGIC AND EVALUATION METHOD
Test tone output
• Pro Logic ON Normal mode
Press the remote control TEST TONE button.
→Output of only L-ch →Output of only C-ch
↑ ↓
Output of only S-ch ←Output of only R-ch
The test tone (noise) is repeatedly output for output period
(2 sec).
In this case the following indication appears repeatedly.
→TEST →L-ch →C-ch
↑ ↓
S-ch ← R-ch
• Pro Logic ON Phantom mode
Press the remote control TEST TONE button.
→Output of only L-ch →Output of only R-ch
↑ ↓
←Output of only S-ch
The test tone (noise) is repeatedly output for output period
(2 sec).
In this case the following indication appears repeatedly.
→TEST → L-ch → R-ch
↑↓
←S-ch←
Outline
• Namely, two speakers are connected in parallel to one
amplifier.
• In the Pro Logic BYPASS mode the amplifier for C-ch
(centerchannel)andtheamplifierforS-ch(surroundchannel)
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.
•Inthe Phantommodeof ProLogicON modetheamplifier for
C-ch is in MUTE state, so that the SP output is cut. The
amplifierforS-ch(surround)isinoperativestate,sothatthe
SP output appears
•State of element output and terminal output in specific mode
Relation between VIDEO IN input and output in Pro Logic
ON state
(1) L-ch/R-ch same phase input into VIDEO IN input jack in
VIDEO Function mode
Output point Normal mode
Output point Phantom mode
(2) L-ch/R-ch reverse phase input into VIDEO IN input jack in
VIDEO Function mode
(Reverse phase: Phase difference between L and R is 180°)
Output point Normal mode
SP out L-ch Almost no output (only omitting component)
(SO901) R-ch Almost no output (only omitting component)
(SO901) SP out C-ch Almost no output (only omitting component)
(SO901) SP out S-ch Input signal is output.
Output point Phantom mode
SP out L-ch Almost no output (only omitting component)
(SO901) R-ch Almost no output (only omitting component)
(SO901) SP out C-ch SP cut, no output
(SO901) SP out S-ch Input signal is output.
• Accordingly, if you want to output signal waveform to C-ch
SP out, give the same phase input into L-ch/R-ch INPUT in
the Pro Logic Normal mode.
Ifoneofchannelsreceivesinput,C-chdoesnotoutput. Only
L-ch or R-ch outputs.
• IfyouwanttooutputsignalwaveformtoS-chSPout,youcan
use either Normal mode or Phantom mode. However, 180°
reverse phase input must be given to L-ch/R-ch INPUT.

•The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas-
sis 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.
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
electrolyticcapacitor,theexpression“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.
