I have a problem with my audio power amplifier circuit :
When i power this circuit for the first time (system being off for a long time) everything is O.K. but if i reset input power , amplifier starts again after a long delay (about 2 minutes) and then there is loud "pop & click" at outputs.
Load speakers are 3W and 4 ohm.
Speaker P/N is : AS07104PO-WR-R from PUI Audio Inc.
*Speakers are always connected .
*Inputs to this amplifier is coming from an analog switch which change audio path to this amplifier or external amplifier .
*During this transition speakers are completely silent and there is no noise at all.
Can you help me to fix this problem ?
