Making noise when higher.
Temperature feature to be increased accordingly as in higher AV
value.
When lower,to be trended of Oscillation.
Setting up low band Cut-off frequency (fL).
More higher,the rise time become longer.
The more higher in value,the high band THD,due to phase slipping
to be deteriorated.
When lower,to be trended of oscillation.
Inserting near around at V+ and the GND pin.
Inserting near around at V+ and the GND pin.
To be examined at around pure resister Value of speaker load.
