cred ca un potentiometru ar face asa ceva, doar ca nu mai trebuie alimentat.. dar varianta asta poate e buna :finga:

va cer scuze la toti eram obosit si nu mi-am dat seama ce am scris. il folosesc la un mp3 auto iar acesta nu are pe iesiri cu masa comuna.. il pun la amplificator si vreau ca semnalul de pe iesirile de la boxe sa fie din hi output in low output
