IDLE CURRENT ALIGNMENT FOR EVERY POWER AMPLIFIER MODULE
1. Remove the load and the input signal.
2. Connect a digital voltmeter between TP1 and TP2.
3. Switch the amplifier on and, after one minute, adjust R27 to obtain a reading of
5mV ±0.5mV.
4. Leave power on for 3 minutes to allow the idle currents to stabilize. Re-adjust R27
as necessary to obtain a reading of 4.4mV ±0.5mV.
