Idling Current
Required measurement equipment: DC Voltmeter
1. 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.
(2) Presetting
• POWER (Power source switch) OFF
• SPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)
2. Adjustment
(1) emoved top cover and set VR41(FL),VR45(FR),VR42(C),VR44(SL),VR43(SR), on Main Amp. Unit at fully
counterclockwise position.
(2) Connect DC Voltmeter to test points (Front-Lch:CN51,Front-Rch:CN55,CENTERch:CN53,
Surround-Lch:CN52,Surround-Rch:CN54).
(3) Connect power cord to AC Line, and turn power switch "ON".
(4) Presetting.
MASTER VOLUME : "---" counterclockwise (
c
min.)
SPEAKER (Speaker terminal) : No load
(Do not connect speaker, dummy resistor, etc.)
FUNCTION : DVD
(5) Within 2 minutes after the power on, turn VR41 clockwise (
x
) to adjust the TEST POINT voltage to
1.5 mV ± 0.5 mV DC.
(6) After 10 minutes from the preset above, turn VR401 to set the voltage to 2.0 mV ± 0.5 mV DC.
(7) Adjust the Variable Resisters of other channels (VR42-VR45) in the same way.
