41ADJUSTMENTAudio SectionAdjusting Idling CurrentRequired measurement equipment: DC Voltmeter1. Preparation(1) Avoid direct blow from an air conditioner or an electric fan and humidity should be moderate, and place the set atnormal usage environment.Temperature should be at 15 °C ~ 30 °C (59 °F ~ 86 °F).(2) Presetting• POWER (Power source switch) OFF• SPEAKER (Speaker terminal) No load(Do not connect speaker, dummy resistor, etc.)2. Adjustment(1) Remove the top cover and set VR710(FL), VR750(FR), VR730(C), VR720(SL), VR740(SR), on MAIN AMP UNIT atfully counterclockwise (c) position.(2) Connect DC Voltmeter to test points (FRONT-Lch: CN710, FRONT-Rch: CN750, CENTER ch: CN730, SURROUND-Lch: CN720, SURROUND-Rch: CN740).(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 STEREOFUNCTION : DVD(5) Within 2 minutes after the power on, turn VR710 clockwise (x) to adjust the TEST POINT voltage at1.5mV ± 0.5mV DC.(6) After 10 minutes from the preset above, turn VR710 to set the voltage to 2.0mV ± 0.5mV DC.(7) Adjust the Variable Resistors of each channel(VR720-VR750) in the same way.CN740VR710 VR720 VR730 VR740 VR750CN710 CN720 CN730 CN750F Lch S Lch C ch S Rch F RchDC VoltmeterMAIN UNIT ASS'Y
