Idling Current (1U-3232-1)
Required measurement equipment : DC Voltmeter
Preparation
(1) Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room tempereture 15 °C ~ 30 °C
(59 °F ~ 86 °F).
(2) Presetting
l POWER (Power sourse switch) → OFF
l SPEAKER (Speaker terminal) → No load (Do not connect speaker, dummy resistor, etc.)
Adjustment
(1) Remove top cover and set VR501, VR502, VR503, VR504, VR505, on 1U-3232-1 (Power Unit) at counterclockwise
(
) fully.
(2) Connect DC Voltmeter to test points (FRONT-Lch: TP501, FRONT-Rch: TP502, CENTER ch: TP505, SURROUND-Lch:
TP503, SURROUND-Rch: TP504).
(3) Connect power cord to AC Line, and turn power switch "ON".
(4) Presetting. MASTER VOLUME : "---" counterclockwise (
min.)
MODE : 5CH STEREO
FUNCTION : CD
(5) Allow 2 minutes, and turn VR501 clockwise ( ) and adjust the TEST POINT voltage to 1.5 mV ±0.5 mV DC.
(6) After 10 minutes from preset, turn VR501 to set the voltage to 3 mV ±0.5 mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
(8) After 5 minutes from (6), turn VR501 to set the voltage to 3 mV ±0.5 mV DC.
(9) Adjust the Variable Resistors of other channels in the same way.
