DENON AVR X3100W
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℃ ~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 PCB as far anticlockwise(c) as possible.
(2) Connect the DC Voltmeter test points.

CENTER ch ： CN735
SURROUND-Lch ： CN745
SURROUND-Rch ： CN755
SURROUND-BACK Lch ： CN765
SURROUND-BACK Rch ： CN775
(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 ： "---" anticlockwise (c min.)
SPEAKER (Speaker terminal) ： No load
( Do not connect equipment such as speakers or dummy resistors. )
MODE ： MCH STEREO
FUNCTION ： DVD
(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.
