2. CAUTION
The layout of this amplifier is well concerned for sound quality.
1. When screws and washers are removed, those parts must
be set to the same places.
2. When wires are removed, the wires must be installed in the
same roots, same places.
3. Do not hold the side panel (007D) to move the unit when
the unit is disassembled.

Adjustment Procedure
Set the power voltage to rated voltage for this adjustment
DC Offset Voltage Adjustment
3. ALIGNMENTS
1.
Before turning on the power,
Insert Digital Voltage Meter between the SPEAKER
SYSTEMS A (L CH) "+" and "".
Insert Digital Voltage Meter between the SPEAKER
SYSTEMS R (R CH) "+" and "".
2.
Turn on the power, VOLUME is set as
.
3.
Press the SPEAKER A button.
4.
After turn on the power and 2 minutes pass, first L CH is
adjusted.
The variable resistor R608 on P601 is turned with
adjustment driver, and the Digital Voltage Meter is adjusted
to "0mV±3mV".
5.
Then, R CH is adjusted.
The variable resistor R708 on P701 is turned with
adjustment driver, and the Digital Voltage Meter is adjusted
to "0mV±3mV".

Idling Current Adjustment
1.
After DC Offset Voltage Adjustment is completed, adjust
the Idling Current with the variable resistor R619 and R719
on the PCB (P601/P701).
2.
Turn off the power.
3.
"+" of Connect Digital Voltage is connected to the No. 1
pin and connected "" to No. 3 pin of J653.
4.
"+" of Connect Digital Voltage is connected to the No. 1
pin and connected "" to No. 3 pin of J753.
5.
Before turning on the power, R619 and R719 have been
counter clockwise turned with the adjustment driver.
6.
Turn on the power, VOLUME is set as
.
7.
With seeing the digital voltage meter turn the variable
resister clockwise slowly to adjust the idling current.
· Idling adjustment with R619 (R719).
· Turn R619 (R719) clockwise to increase the idling current.
· The adjustment value of idling current is
11mV(55mA) ±0.5mV(2.5mA) each.
8. After 2 minutes, repeat the same procedure as 7.
· Turn R619 (R719) clockwise to increase the idling
current.
· The adjustment value of idling current is
11mV(55mA) ±0.5mV(2.5mA) each.
Adjustment is completed.
9. Remove connection cable, attach the top cover.
(Idling current decreases with the temperature rise inside the
unit, and it is set to 10mV (50mA) of setting value in about 30
minutes after turn on the power.)
