Adjusting Idling Current
Required measurement equipment: DC Voltmeter
1. Preparation
(1) Avoid direct blow from an air conditioner or an electric fan and humidity should be moderate, and place the set at
normal usage environment.
Temperature should be at 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.)
2. Adjustment
(1) Remove the top cover and set VR710(FL), VR750(FR), VR730(C), VR720(SL), VR740(SR), on MAIN AMP UNIT at
fully counterclockwise (
c
) position.
(2) Connect DC Voltmeter to test points (FRONT-Lch: CN710, FRONT-Rch: CN750, CENTER ch: CN730, SURROUND-
Lch: CN720, SURROUND-Rch: CN740).
(3) Connect the power cord to AC Line, and set the power switch to "ON".
(4) Presetting.
MASTER VOLUME : "---" counterclockwise (
c
min.)
SPEAKER (Speaker terminal) : No load
(Do not connect speaker, dummy resistor, etc.)
MODE : MCH STEREO
FUNCTION : DVD
(5) Within 2 minutes after the power on, turn VR710 clockwise (
x
) to adjust the TEST POINT voltage at
1.5mV ± 0.5mV DC.
(6) After 10 minutes from the preset above, turn VR710 to set the voltage to 2.0mV ± 0.5mV DC.
(7) Adjust the Variable Resistors of each channel(VR720-VR750) in the same way.
