Adjustment - Denon AVR-X7200W Service Manual

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)
• SPEAKER (Speaker terminal)
( Do not connect equipment such as speakers or dummy resistors. )
2. Adjustment Procedure
(1) Remove the top cover and turn V101(ALL Channel) of the AMP PCB as far anticlockwise( c ) as possible.
(2) Connect the DC Voltmeter test points.
