Denon AVR-X2400H 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 VR401( (ALL Channel) of the AMP PCB counterclockwise(
c
) as far
as possible.
(2) Connect the DC Voltmeter to the test points.

SURROUND-Rch : CP505 : VR405
SURROUND-BACK Lch : CP506 : VR406
SURROUND-BACK Rch : CP507 : VR407
(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 : MCH STEREO
FUNCTION : DVD
(5) Turn VR401 clockwise (
x
) and adjust the voltage of the test point to "
8.0mV ± 0.5mV DC
" within 2
minutes.
(6) Check whether the voltage is within the range "
8.0mV +1mV/-2mV DC
" 10 minutes after adjust-
ment.
(7) Adjust the variable resistance of each channel using the same method.
