Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.

SECTION 1
SERVICE NOTE
Clearing the Protector During Repairs
• OVER CURRENT : Detects overcurrent during output.
• OFF SET : Detects DC offset at the speaker terminal.
1. Clearing the OVER CURRENT protector
• When the position of the MODE switch (S801/power board)
is set to HI-CURRENT :
Cut the jumper wire JW230 of the amplifier board.
2. Clearing the OFF SET protector
• Cut the jumper wire JW307 of the amplifier board.
3. TESTTONE Function
1Press the TEST TONE button (S710/SUB2 board) with the
power ON. The amplifier is normal if sound is produced from
the speaker.
2If no sound
: Problem causer by incorrect connecttion of the power supply
system or sperker system.
: The signals input by the RCA cable before the amplifier system
are abnormal.

ELECTRICAL ADJUSTMENT
IDLING CURRENT ADJUSTMENT
• Perform adjustments in the HI-VOLTAGE mode.
1Adjustment point
Semi-fixed resistors VR101, VR201, VR301, VR401, VR501,
VR502 of amplifier board
2Precautions on adjustments
1. Set the RCA input terminal to open.
2. Apply a voltage of 14.4V between the +12V terminal, REMOTE
terminal, and GND terminal.
3. Rotate the above semi-fixed resistors completely in the counter-
clockwise direction while observing the component side.
4. Check that the voltage at the adjustment point becomes 0 mV in
step 2.
5. Fine adjustments may be required according to the characteris-
tics of the MOS-FET used.
• When adjusting the idling current
Rotating the semi-fixed resistor in the clockwise direction:
Increases the idling current
Rotating the semi-fixed resistor in the counterclockwise direction:
Decreases the idling current
*Take note that rotating excessively in the clockwise direction
will increase the idling current suddenly.
3Approximate adjustment values
Adjust as follows so that the following voltages become
1.2 to 0.3 mV around 0.7 mV .
FL channel :
Voltage betweenTP7 andTP6: UseVR101of theamplifier board
FR channel :
Voltage betweenTP7 andTP5: UseVR201of theamplifier board
RL channel :
Voltage betweenTP7 andTP4: UseVR301of theamplifier board
RR channel :
Voltage betweenTP7 andTP3: UseVR401of theamplifier board
SUBWOOFER Channels :
First, adjust so that the voltage between TP1 and TP2 becomes
1.2 to 0.3 mV around 0.7 mV using VR501 of the amplifier
board.
Next, adjust so that the voltage between TP1 and TP2 becomes
2.4 to 0.6 mV around 1.4 mV using VR502 of the amplifier
board.”

specified.
•C: panel designation.
•U: B+ Line.
• Powrvoltageis dc14.4V andfedwith regulateddc power
supply from +12V and REMOTE terminals.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark: POWER ON
*: Impossible to mersure
• Voltages aretaken withaVOM (Inputimpedance 10MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
