tda 7240 help :((

Recommended Posts

Hmm....se pare ca e o chestie ciudata cu tda-urile astea...eu am folosit un TDA2822 cu schema din datasheet si aveam un zgomot de fond enervant. Daca in difuzor mai mergea, in casti (ca este folosit si ca amplif pentru casti) se auzea infect (zgomotul de fond se auzea mai tare ca muzica).Din pacate nu am reusit sa ii dau de cap

Mda am vazut ..nu am reusit sa ii facem nimik..pana la urma mere acum i punte pe un woofer mai mic (ca pentru camera) si nu e asa deranjant zgomotul de fond ca nu il reproduce difuzorul...daca pui amplificatorul pe un satelit ceva te scoate din minti zgomotul de fond ....am incercat si filtrare de 100.000 de micro .. :axe: si nimik ...nu vrea nici cum sa mearga...In fine asta e acum isi face treaba binishor in punte,respectivul e multumit de ce i-a iesit,eu personal crek dupa atata chin faceam altceva :smt067 ...poate o sa mai incerc pe viitor schema...cand nu o sa am ce face ca atunci lucrezi fara nervi... :weedman: pana atunci toate cele bune pt toti :smt006
