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.
