ALIGNMENT PROCEDURE (C352)
I. INITIAL ADJUSTMENT (No load connected) A. OUTPUT OFFSET VOLTAGE 1. Connect a DC Millivoltmeter to L Channel speaker output terminals. 2. Turn unit �ON� and adjust VR101 (100ohms) to get a reading on IC107 Pin 1, which must be <100mV. 3. Connect the DC Millivoltmeter to R Channel speaker output terminals and adjust VR102 (100ohms) to get a reading on IC108 Pin 1, which must be <100mV. B. IDLING CURRENT 1. Leave power �ON� for a minimum of 5 minutes. 2. Connect a DC Millivoltmeter to TP101 and TP102, then adjust VR103 (300ohms) for 5-6.5mV reading on meter. 3. Connect a DC Millivoltmeter to TP103 and TP104, then adjust VR104 (300ohms) for 5-6.5mV reading on meter. II. FINAL ADJUSTMENT Repeat procedure A and B for offset voltage and idling current alignment respectively.
