Denon AVR-X3100W - Adjustment

ADJUSTMENT
Adjusting Idling Current
1. Preparation
(1) Prepare a DV voltmeter.
(2) Place the unit in 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 VR714, VR724, VR734, VR744, VR754, VR764, VR774 of the AMP UNIT as far
anticlockwise(
c
) as possible.
(2) Connect the DC Voltmeter test points.

(5) Turn VR714 clockwise (
x
) and adjust the voltage of the test point to "
6.5mV ± 0.5mV DC
" within 2 minutes.
(6) 10 minutes after the preliminary adjustment, turn VR714 and set the voltage as "
8.0mV ± 0.5mV DC
".
(7) Adjust the variable resistance of each channel using the same method.
