Dragi prieteni,

 

Va rog sa ma ajutati cu o sugestie legata de urmatoarele fenomene. La pornire uneori,  se aude doar un canal, problema se rezolva cu rotirea potentiometrului catre jumatate de cursa. Sunetul revine dar impresia este ca la volum mic sunetul este mai slab pe acest canal. La volum peste 25% nu mai sesizez diferente intre canale. Mentionez ca amplificatorul este nou cumparat de nou, a functionat numai la volume mici, intr-o camera de bloc. Boxele sunt Dali Zenzor3, cumparate noi.

 

Multumesc!
