IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment covers
or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5 kohm, 10 watt resistor
paralleled by a 0.15 µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

ADJUSTMENT
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 preformed
automatically. Therefore, playback of each disc can be
preformed under optimum conditions.
1-BIT AMP. SECTION

DESCRIPTION OF CIRCUIT FOR 1-BIT UNIT
(SEE THE WIRING DIAGRAMS ON PAGES 26 AND 27.)
Input section
Signals from CNA101 are coupled by CA100 and CA101 and
then sent into the A/D converter IC (ICA100).
modulation 1-bit converter
Signals from the A/D converter IC (ICA100) are converted to
1-bit signals and sent differentially. Refer to the technical
manual of SM-SX100 for the details of conversion to 1-bit
signals.
Low pass filter circuit
1-bit signals switched by the output IC (ICA101 and ICA102)
are converted to analog signals through the lowpass filter
consisting of LA101 ~ LA107. The low pass filter functions
when a frequency exceeds 20 kHz, and reduces it by approx.
3 dB when it reaches approx. 40 kHz.

Dynamic feedback circuit
The 1-bit signals switched by the output IC (ICA101 and
ICA102) oscillate between positive and negative voltage.
After resistance-division, the signals are fed back to the A/D
converter IC (ICA100) through NF resistance 75 kohms (RA155
~ RA158). The peak-to-peak voltage reaches approx. 5 V.

TO CHECK AND CANCEL PROTECT CIRCUIT DETECTION LINE
1: In this model the microcomputer (IC701) detects the following
malfunctions once power is supplied, and cuts off power
from all the parts except for the circuit driving the
microcomputer.
1
Abnormal drop in the output voltage of each regulator
(below approx. 1.5 V)
Power is cut off instantly without display.
2
Output offset over voltage of the 1-bit amplifier
(above approx. DC 2 V)
3
Mains overvoltage of the 1-bit amplifier
(above approx. DC 5.5 A)
Power is cut off instantly without display.
4
Defects in the cooling fan or its drive circuit
(when stopped)
Power is cut off after “FAN LOCK” is displayed.
2: Criteria for abnormality, and checking and cancelling the
detection line
The criteria:
1
The voltage of pin 6 (PROTECT) on IC701.
2
The voltage of pin 32 (OFFSET) on IC701: Low (below
approx. 1 V) (abnormal) and High (above approx. 2.5
V) (normal) .
3
The motor stops when it is above approx. 1 V.
If the voltage of pin 10 (FAN LOCK) on IC701 is not
between approx. 0.21 V and 1.20 V whilst the motor
rotation is controlled, it is judged as abnormal.
11
1
Abnormal drop in the output voltage of each regulator
11
Connect a measuring device (such as an oscilloscope) to
the stabilizing output of the regulator, and turn on the unit.
If the detected voltage is extremely lower than the voltage
on the circuit diagram (below approx. 1.5 V), the regulator
itself or the circuit is defective.
22
2
Output offset overvoltage of the 1-bit amplifier
22
Adjust the voltage of the output offset. If a protective
operation is still activated, ICA401 on the 1-bit amplifier
could be defective (the detection circuit of the speaker
output DC voltage).
Checking and cancelling the detection line:
Caution: If the PROTECT/OFFSET detection line is
disconnected in case of 1, 2 or 3 above, a
protective operation does not function. The
disconnection by output short-circuit of each
regulator may cause the parts or PCBs to burn
out and therefore do not disconnect the detection
line when the cause is not identified.
(Power supply can be detected with an
oscilloscope or like during approx. 0.5 seconds
after an abnormality is found. Note that the
detection would be difficult with a tester as the
voltage rises and falls rapidly.)

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 pico-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.

2. In the CD section, the CD is stopped.
• Parts marked with “ 1 ” ( ) are important for
