Sziasztok.
Szerintetek javíthatóak lehetnek ezek a hibák?
Ha bekapcsolom zúg vmi a mélyládában. Bluetooth és wireless kapcsolat nem működik, a csatlakozás Jack csatlakozóval. A hangprojektor részében az egyik hangszóró halkabban szól.
Mi okozhatja ezeket a hibákat?
Várom a válaszotokat.
Köszönöm.

Dear Friends,
I am having a problem with the above mentioned amp. When I increase the volume from 0 to a quarter level the sound is OK. If I increase the level above quarter onwards , the sound becomes fuzzy and distorted. I have tried replacing the 2 filter capacitors(8200uf 50v) with 2 (15000uf 50v) caps but it is the same. Can someone give me a clue what can be causing this problem.
Thanks
Carlos Rajoo
Sziasztok!
Egy autórádióban cseréltem végfokot, TA8276H helyett raktam be TDA7560-at. Szól, de csúnyán, a híd kimenete el van billenve, az egyiken 1V körül, a másikon 6,5V, mindez 11,8V-os tápfesznél. Van ötletetek? Eg Merci rádióban van, 3 rétegű nyák, de a bemenetek szerintem biztos le vannak választva kondival.
Hibás volt a beépített IC
Üdv: Jácint
Köszi a segitséget az AX550-ből össze tudom hozni az y-lon elütésért
elnézést csak egy kicsit kapkodtam.
