DC OFFSET VOLTAGE The DC OFFSET between OFFSET Test Point and AGND must be within 0+/-20mV. B. IDLING CURRENT The idling current in the output stage of the poweramp should be set to 30mA+/-5mA per pnp-npn transistor pair (This means the mid point voltage is 6.6mV with down limit of 5.5mV and up limit of 7.7mV). The alignment procedure is: At first, adjust RV102 (Marked as “Idling Current ADJ” in the drawing below) for a voltage of 6.6mV +/- 1mV between Test point 1 and 2. Then preheat the unit for 1 minutes, let idling current settled and then readjust to 6.6mV +/- 1mV. This is a no-load adjustment. Pls note: Though the idling current is set as 6.6mV +/-1mV during the adjustment, due to the influence of varied ambient temperature and mains voltage etc., the idling current will drift after some time. During the normal checking of idling current in the service field, its acceptable as long as the voltage is in the range of 5.5mV7.7mV C. ISC SENSITIVITY The ISC sensing voltage can allow 0mV+/-50mV. But, for the alignment process in our factory, we tighten the limit to 0mV+/-10mV. That is to adjust Pot RV103 (as marked as “ISC SENS ADJ” in the below drawing) to get a voltage between the “ISC SENSE TEST POINT” and AGND to be 0mV+/-10mV. - 5 -ALIGNMENT PROCEDURELEFT POWERAMP
