SHOCK, FIRE HAZARD SERVICE TEST :
CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC
cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product
and controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied,
and verified before it is return to the user/customer.

Explanation of microprocessor (QU01) [PROT-1 (pin54) and
PROT-2 (pin53)].
[A] The PROT-1(pin54) 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), Q905 or Q906 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 (Q628, Q629, Q728, Q729).
If an electric current of over 10A flows in Q628 or Q629,
Q630, Q631 and Q908 turn on, and the signal from the
PORT-1 terminal will change to L from H.
If an electric current of over 10A flows in Q728 or Q729,
Q730, Q731 and Q908 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 (R659 and
R759) will turn on Q907 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 (pin40) changing to L from H and the speaker relays
L901 ~ L905 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 h(v WITHIN AS SHORT A
period of time as one second or less.
4HE MESSAGE h02/4%#4v FLASHES ON THE DISPLAY
thereby indicates that the protection circuit has come
into operation and automatically turns down the volume.
The protection circuit is deactivated after approximately
8 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 POW-1 (pin25) and
POW-2 (pin24) changing to L from H and Power relay
L852 and L853 turned off
Then, the OPERATION 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 (pin54) remains
“L”, which constitutes an abnormality, the unit shuts down
approximately 3 seconds later and the OPERATION
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 (pin53) 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 +58V and -58V. If the voltage at
the connection point of R809 and R810 exceeds DC
±1.2V, Q803 or Q804 will turn on to change the signal
from the PROT-2 (pin53) to L from H.
Detection of an abnormality in the preamp power supply 2.
circuit.
This port monitors the midpoint voltage between +30V
and -30V. If the voltage at the connection point of R813
and R814 exceeds DC ±1.2V, Q805 or Q806 will turn on
to change the signal from the PROT-2 (pin53) to L from H
Detection of an abnormality in the function relay power 3.
supply circuit.
If the +24VLB of the relay power supply receives an
electric current of over 120mA, Q809 and Q805 will turn
on to change the signal from the PORT-2 (pin53) to L
from H.
The Fuse (F851) inside the SOFT START PWB (P851) 4.
blows, the signal from the PROT-2 (pin53) terminal will be
changed to L from H.
If any of the above four abnormalities is detected, the signal
from the POW-1 (pin25) and POW-2 (pin24) changing to L
from H, the power relay L852 and L853 will be turned off
and the unit will be shut down. Then, the OPERATE 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 (pin53) remains L after the power is switched
on again, the unit will be shut down again three seconds
later with the OPERATE 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.
