Sziasztok!
A címbeli 5.1 erősítő a subwoofer kimeneten nem ad ki hangot. A bemenetről a sztereo jel eljut az R2A15218FP hangprocesszorba, onnan pedig A/D konvertálás és mátrixolás után megy az erősítőpanelen keresztül a hangfalkimenetre. Elképzelhető, hogy a hangprocesszor subwoofer kimenete rossz úgy, hogy a többi 5 kimenete kifogástalanul és tisztán szól?
Amúgy a szerviz manuálja letölthető a netről.
Minden segítséget köszönök.

Találtam ezt a dobozt, az SP-410D aktív subwoofert.
Első mérésre a végfok IC zárlatos.
Ismeri-e valaki ennek a végfok típusát?
2 db. 5W-os, 1 db. 20W-os végfok van egy tokban.
Mérgemben kinyomta a vakerára, de ha kapható lenne ilyen IC, talán érdemes lenne kicserélnem.
Valamire csak jó lenne....
