Intrebare despre un subwoofer..

Recommended Posts

Guest kristian

Am un subwoofer sw-5.1 1500 ver2.0. Daca ii scot transformatorul si il leg la baterie de masina de 12v va functiona?

Pai vezi cat scoate transformatorul si daca scoate 12V atunci merge. Dar eu nu prea as crede...

Daca dupa redresare si filtrare el  punea la bataie 12v, nu vad de ce nu. Eu am facut oarecum asa ceva cu unul micut si mi-a mers. Se alimenta la 220vac si dupa traf+redresare+filtrare avea cam 6 v, eu am anulat trafu si redresarea si filtrarea si am pus o mufa usb si a mers.

Va funcţiona bine  la 12V, dar vezi cum alimentezi şi cealaltă secţiune, de 14V. Ar trebui practic să le pui în paralel. Probabil nu ai alimentat partea de preamplificare/corector de ton

nu  e  bine  cum  faci  .  decupleaza  trafo  de  alimentare  de  la  puntea  redresoare  si  masoara  tensiunea /  tensiunile  alternative  in  gol  debitate  .   comunica-ne  rezultatul   si  mai  vedem  dupa  aceea  ce  si  cum .

Ai masurat tensiunile AC de la iesirile trafului?

Cite iesiri are traful?

Pune dom'le niste poze citete si reprezentative cu interiorul aparatului. Nu de alta, dar mai toti avem globurile de cristal date la reglare si etalonare.
