ALIGNMENT PROCEDURES
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 VR21 (100 ohms) to get the reading of 0V+/-30mV. 3. Connect the DC Millivoltmeter to R Channel speaker output terminals and adjust VR11 (100ohms) to get a reading of 0V+/-30mV. B. IDLING CURRENT 1. Connect a DC Millivoltmeter to TP1 and TP2 and adjust VR12 (300 ohms) for 3-5mV reading on meter. 2. Connect the DC Millivoltmeter to TP3 and TP4 and adjust VR22 (300 ohms) for 3-5mV reading on meter. 3. Leave power on for a minimum of 5 minutes.
II. FINAL ADJUSTMENT Repeat procedure A and B for offset voltage and idling current alignment respectively.
