Adjusting Idling Current
Required measurement equipment: DC Voltmeter
1. Preparation
(1) Temperature should be at avoid direct blow from an air conditioner or an electric fan and humidity should be
moderate, and place the set at normal usage environment.
15 °C ~ 30 °C (59 °F ~ 86 °F)
(2) Presetting
• POWER (Power source switch) STANDBY
• SPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)
2. Adjustment
(1) Remove the top cover and set VR401, VR402, VR403, VR404, VR405, VR406, VR407 on at fully 7CH AMP UNIT at
fully counterclockwise (
c
) position.
(2) Connect DC Voltmeter to test points (FRONT-Lch: TP401, FRONT-Rch: TP402, CENTER ch: TP403, SURROUND-
Lch: TP404, SURROUND-Rch: TP405, SURROUND-BACK Lch: TP406, SURROUND-BACK Rch: TP407.
(3) Connect the power cord to AC Line, and set the power switch to "ON".
(4) Presetting.
MASTER VOLUME : "---" counterclockwise (
c
min.)
SPEAKER (Speaker terminal) : No load
(Do not connect speaker, dummy resistor, etc.)
MODE : MCH STEREO
FUNCTION : DVD
[AVR-1913E3/AVR-2113CIE3, E1C model]
(5) Within 2 minutes after the power on, turn VR401 clockwise (
x
) to adjust the TEST POINT voltage to
2.0mV ± 0.5mV DC.
(6) After 10 minutes from the preset above, turn VR401 to set the voltage to 3.0mV ± 0.5mV DC.
(7) Adjust the Variable Resistors of each channel in the same way.
[AVR-2113E2 model]
(5) Within 2 minutes after the power on, turn VR401 clockwise (
x
) to adjust the TEST POINT voltage to
6.5mV ± 0.5mV DC.
(6) After 10 minutes from the preset above, turn VR401 to set the voltage to 8.0mV ± 0.5mV DC.
(7) Adjust the Variable Resistors of each channel in the same way.
