Adjusting 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 (59 °F ~ 86 °F).
(2) Presetting
• POWER (Power source switch)
STANDBY
• SPEAKER (Speaker terminal)
No load
(Do not connect speaker, dummy resistor, etc.)
2. Adjustment
(1) Remove top cover and set V101,V201,V301,V401,V501,V601,V701,V801,V901 on 9CH AMP UNIT at fully
counterclockwise (c) position.
(2) Connect DC Voltmeter to test points (FRONT-Lch: N9039 9pin-10pin, FRONT-Rch: N9040 1pin-2pin, CENTER ch:
N9039 7pin-8pin, SURROUND-Lch: N9039 5pin-6pin, SURROUND-Rch: N9040 3pin-4pin, SURROUND-BACK
Lch: N9039 3pin-4pin, SURROUND-BACK Rch: N9040 5pin-6pin, FRONT-HEIGHT Lch: N9039 1pin-2pin, FRONT-
HEIGHT Rch: N9040 7pin-8pin.
(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.)
MODE
: MCH STEREO
FUNCTION
: DVD
(5) Within 2 minutes after the power on, turn V101 clockwise (x) to adjust the TEST POINT voltage to
8mV ± 0.5mV DC.
(6) After 10 minutes from the preset above, turn V101 to set the voltage to 12mV ± 0.5mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
