Adjusting Idling Current
Required measurement equipment: DC Voltmeter
1. Preparation
(1) Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room temperature
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 top cover and set VR714,VR724,VR734,VR744,VR754,VR764,VR774 on 7CH AMP UNIT at fully
counterclockwise (
c
min) position.
(2) Connect DC Voltmeter to test points (FRONT-Lch: CN715, FRONT-Rch: CN725, CENTER ch: CN735, SURROUND-
Lch: CN745, SURROUND-Rch: CN755, SURROUND-BACK Lch: CN765, SURROUND-BACK Rch: CN775.
(3) Connect power cord to AC Line, and turn power switch
"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
(5) Within 2 minutes after the power on, turn VR714 clockwise (
x
) to adjust the TEST POINT voltage to
6.5mV ± 0.5mV DC.
(6) After 10 minutes from the preset above, turn VR714 to set the voltage to 8mV ± 0.5mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
