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
POWER (Power sourse switch)
→
OFF
SPEAKER (Speaker terminal)
→
No load (Do not connect speaker, dummy resistor, etc.)
Adjustment
(1) Remove top cover and set VR101, VR102, VR201, VR202, VR301, VR401, on 1U-3368-1 (Power Unit) at fully
counterclockwise ( ).
(2) Connect DC Voltmeter to test points (FRONT-Lch: TP101, FRONT-Rch: TP102, CENTER ch: TP103, SURROUND-Lch:
TP101, SURROUND-Rch: TP103, SURROUND BACK-ch: TP102).
(3) Connect power cord to AC Line, and turn power switch "ON".
(4) Presetting. MASTER VOLUME : "---" counterclockwise ( min.)
MODE : 6CH STEREO
FUNCTION : CD
(5) Allow 2 minutes, and turn VR101 clockwise ( ) to adjust the TEST POINT voltage to 6.5 mV
±
0.5 mV DC.
(6) After 10 minutes from preset, turn VR101 to set the voltage to 8 mV
±
0.5 mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
(8) After 5 minutes from (6), turn VR101 to set the voltage to 8 mV
±
0.5 mV DC.
(9) Adjust the Variable Resistors of other channels in the same way.
