Insert Digital Voltage Meter between the SPEAKERS SYSTEM A (R CH) + and -.Adjust the VOLUME to MIN.2. Turn on the power. Then turn the SPAKER
23、S knob to A. 3. Adjustment is started immediately after a speaker relay turns on.First L CH is adjusted. 4. The variable resistor R639 on P101 is turned with adjustment driver, and the Digital Voltage Meter is adjusted to 0 mV 3 mV.Then, R CH is adjusted. 5. The variable resistor R640 on P101 is tur
24、ned with adjustment driver, and the Digital Voltage Meter is adjusted to 0 mV 3 mV.NOTE : DC offset voltage drops when turn the semi-fixed resistor (R639 and R640) clockwise. DC offset voltage rises when turn the semi-fixed resistor un-clockwise. Please turn it slowly, because value of Digital Volta
25、ge Meter changes slowly.Although after-adjustment DC offset voltage has some 6. change, Please check that the range of DC offset voltage between L ch (R ch) + and L ch (R ch) - terminal of SPEAKERS SYSTEM A is 0 mV 20 mV.
