Please can I have service manual for this amplifier, I received with no sound amplifier IC and I don't know what chip is used to boost the sound. Mainboard have 2 codes one is P0AA8 on a sticker and the other is right to 220V connector PCB325041REVG_03. I upload some photos. Thank you
this is a 99% popular operational amplifier, from the power pins (pin 4 and 8) it looks like a double op-amp. Put anything there to test, TL072, NE5532 in the SMD version.
The discussion revolves around the request for a service manual for the BEHRINGER EUROPORT EPS500MP3 amplifier, specifically to identify the sound IC used for amplification. Users have suggested that the amplifier may utilize the TDA8954TH chip and mentioned the possibility of using common operational amplifiers like TL072 or NE5532 for testing purposes. One user has offered to share complete circuit schematics with notations, while others have expressed their need for the service manual or schematics. The mainboard codes provided include P0AA8 and PCB325041REVG_03. Summary generated by the language model.
