Adjust the VOLUME to MIN.2.
Turn on the power. Then turn the SPAKERS knob to A. 3.
Adjustment is started immediately after a speaker relay
turns on.
First L CH is adjusted. 4.
The variable resistor R639 on P101 is turned with
adjustment driver, and the Digital Voltage Meter is
adjusted to "0 mV ± 3 mV".
Then, R CH is adjusted. 5.
The variable resistor R640 on P101 is turned with
adjustment driver, and the Digital Voltage Meter is
adjusted to "0 mV ± 3 mV".
NOTE : DC offset voltage drops when turn the semi-fixed
resistor (R639 and R640) clockwise. DC offset
voltage rises when turn the semi-fixed resistor unclockwise. Please turn it slowly, because value of
Digital Voltage Meter changes slowly.
Although after-adjustment DC offset voltage has some 6.
change, Please check that the range of DC offset voltage
between L ch (R ch) "+" and L ch (R ch) "-" terminal of
SPEAKERS SYSTEM A is "0 mV ± 20 mV". CHART OF

Explanation of microprocessor (QU01) [PROT-1 (pin6) and
PROT-2 (pin7)].
[A] The PROT-1 (pin6) is the port to detect the following
abnormalities of the Power AMP
Detection of an abnormality in the DC offset voltage from 1.
the Speaker Output terminal.
If the voltage from the Speaker Output terminal exceeds
approximately 1.2V (DC), Q955 or Q956 will turn on and
the signal from the PROT-1 terminal will change to L from
H.
Detection of an abnormal current from the power 2.
transistors (Q713 ~ Q716).
If an electric current of over 7A flows in Q713 or Q715,
Q951, Q953 and Q957 turn on, and the signal from the
PORT-1 terminal will change to L from H.
If an electric current of over 7A flows in Q714 or Q716,
Q952, Q954 and Q957 turn on, and the signal from the
PORT-1 terminal will change to L from H.
Detection of an abnormal temperature of the Heat Sink.3.
If the temperature of the Heat Sink exceeds
approximately +110 degrees C, the posistor (R969) will
turn on Q958 and the signal from the PROT-1 terminal
will change to L from H.

If any of the above three abnormalities is detected, the
signal from the PROT-1 terminal will change to L from H,
and the protection circuit will be activated, the signal from
the SPK_OUT (pin10) changing to H from L and the speaker
relays L751, L752 and L753 immediately turned off.
What this protection operation results in after this depends
on how long the signal from the PROT-1 has to remain L.
s )F THE 02/4 PIN RECOVERS TO ( WITHIN AS SHORT A
period of time as one second or less.
The MUTE indicator starts flickering, thereby indicates
that the protection circuit has come into operation and
automatically turns down the volume. The protection
circuit is deactivated after approximately 15 seconds,
so that readjusting the volume will allow normal use
of the unit again. This protection operation is intended
for the situation wherein the user has misused the unit
temporarily and automatically resets the unit while the
amp circuit is functioning properly.
s )F THE 02/4 PIN REMAINS , FOR MORE THAN ONE SECOND
The amp will be powered off by the P_ON (pin15)
changing to H from L and Power relay L852 turned off
Then, the STANDBY indicator flickers, thereby indicating
that an error has occurred. This protection operation is
intended for a failure in the amp circuit and immediately
turns the power off to avoid the risk of any damage.
Depending on how the user is handling the unit, this
operation may be performed no matter if the amp is
functioning properly.

To check if the amp is in order, switch off the unit and switch
it on again one minute later. This action will deactivate
the protection operation. If the PROT-1 (pin6) remains
"L", which constitutes an abnormality, the unit shuts down
approximately 3 seconds later and the STANDBY indicator
starts flickering.
If the protection operation will not be deactivated after the
power is turned on again, the amp circuit may be broken.
[B] The PROT-2 (pin7) is the port to detect abnormalities
of the power supply circuit.
Detection of an abnormality in the power amp power 1.
supply circuit.
This port monitors the midpoint voltage of the power amp
power supply between +48V and -48V. If the voltage at
the connection point of R801 and R802 exceeds DC
±1.2V, Q903 or Q904 will turn on to change the signal
from the PROT-2 (pin7) to L from H.
Detection of an abnormality in the preamp power supply 2.
circuit.
Q901 and Q902 monitor the midpoint voltage between
+28V and -28V. If the voltage at the connection point of
R905 and R906 exceeds DC ±1.2V, Q901 or Q902 will
turn on to change the signal from the PROT-2 (pin7) to L
from H
Detection of an abnormality in the function relay power 3.
supply circuit.
If the +24VL of the relay power supply receives an
electric current of over 80 mA, Q815 and Q901 will turn
on to change the signal from the PORT-2 (pin7) to L from
H.
If any of the above three abnormalities is detected, the signal
from the P_ON (pin15) terminal will be changed to L from
H, the power relay L852 will be turned off and the unit will
be shut down. Then, the STANDBY indicator flickers and
indicates that an abnormality has occurred.
This protection operation is intended for a breakdown of the
AMP circuit or the power supply circuit and immediately shut
s off the power in order to avoid the risk of damage.
To check if the amp circuit or the power supply circuit is
broken, switch off the power and then switch it on again
one minute later. This action will deactivate the protection
operation.
If the RPOT-2 (pin7) remains L after the power is switched on
again, the unit will be shut down again three seconds later
with the STANDBY indicator flickering.
If the unit is powered on again and yet cannot get the
protection operation deactivated, the amp circuit or the
power supply circuit may be broken.
