ADJUSTMENT
Audio Section
Idling Current (8U-110049, 8U-110067-3, 8U-110074-2)
Required measurement equipment: DC Voltmeter
Preparation
(1) Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room temperature 15°C ~ 30°C
(59°F ~ 86°F).
(2) Presetting
POWER (Power source switch) OFF
SPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)
Adjustment
(1) Remove top cover and set VR501, VR502, on 8U-110067-3 and VR101, VR201, VR301, VR401, VR501, VR601,
VR701 on 8U-110074-2 (POWER AMP Unit) at fully counterclockwise ( ).
(2) Connect DC Voltmeter to test points(8U-110067-3, 8U-110074-2).

(5) Allow 2 minutes, and turn VR101 clockwise ( ) to adjust the TEST POINT voltage to 6.5 mV ± 0.5 mV DC.
(6) After 10 minutes from preset, turn VR101 to set the voltage to 12 mV ± 0.5 mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
(8) After 5 minutes from (6), turn VR101 to set the voltage to 12 mV ± 0.5 mV DC.
(9) Adjust the Variable Resistors of other channels in the same way.
