Am o problema cu amplificatoru. Cind il deconectez de la alimentare (printr-un comutator) se aude un sunet puternic de scurta durata. Cum as putea evita acest sunet? Amplificatoru e pe tda8560q. Schema e pe google. Ar putea cineva sa-mi spuna ce ar trebui sa mai adaug in schema? Mersi.

ai nevoie de o protectie pt boxe care are mai multe rolulri:-decupleaza boxele- imediat ce dispare tensiunea alternativa la bornele transformatorului -imediat ce apare o tensiune continua pe iesirea amplificatorului-realizeaza o intarziere in cuplarea boxelor, de cateva secunde, la pornirea amplificatorului.unele mai evoluate au si rol de protejare al amplificatorului prin decuplarea iesiri acestuia cand iesirea este pusa in scurt
