Adjusting Idling Current - Denon AVR-X6400H Service Manual

ADJUSTMENT

Adjusting Idling Current

1. Preparation
(1) Prepare a DC voltmeter.
(2) Place the unit under normal usage conditions, away from highly ventilated areas such as next to an
air conditioning machine or electric fan.
The set requires an ambient temperature of 15℃ to 30℃ and standard humidity.
(3) Settings of This Unit
• POWER (Power source switch) STANDBY
• SPEAKER (Speaker terminal) No load
(Do not connect equipment such as speakers or dummy resistors.)
2. Adjustment Procedure
(1) Remove the top cover and turn "V101/V201"(ALL Channel) of the AMP PCB counterclockwise( c ) as
far as possible.
(2) Connect the DC Voltmeter to the test points.

(3) Connect the power cord to an outlet. Next, press the power button to turn on the power.
(4) Set this unit as follows.
MASTER VOLUME : "---" ( c min.) : turn counterclockwise to the lowest position.
SPEAKER (Speaker terminal) : No load
(Do not connect equipment such as speakers or dummy resistors.)
MODE : Multi Ch Stereo
FUNCTION : DVD
(5) Turn "V101/V201" clockwise ( x ) and adjust the voltage of the test point to "8.0mV ± 0.5mV DC"
within 2 minutes.
(6) 10 minutes after the preliminary adjustment, turn V101/V201 and set the voltage to "8.0mV ± 2.0mV
DC".
(7) Adjust the variable resistance of each channel using the same method.
