What amplifier IC is used in the Behringer EUROPORT EPS500MP3, and can I get the service schematic for it?
The main power amplifier IC is TDA8954TH [#20635182] Another identified IC on the board is likely a dual op-amp, with TL072 or NE5532 in SMD form suggested as substitutes for testing [#20839649] One reply also says a complete circuit schematic with notations was obtained and may be available [#21104655] The board markings P0AA8 and PCB325041REVG_03 were mentioned, but no thread reply explained them [#20635182]

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.
>>21104655 (I need the electronic diagram, thank you)
I need to know which diode (D24)
I would like the scheme, I have one to renew in my office in Brazil and I don't have the scheme, thank you.
>>21849425 Same issue for me too. When I connect power to the mixer, a couple of LEDs are blinking. Any possibility of getting the service manual? Thanks
Discussion about obtaining the service manual or schematic for the Behringer EUROPORT EPS500MP3 powered amplifier/mixer. The original fault is a missing sound amplifier IC on the mainboard, with PCB markings P0AA8 and PCB325041REVG_03 near the 220V connector. A response identifies the power amplifier IC as TDA8954TH, and another reply suggests the small dual op-amp stage may use a common SMD device such as TL072 or NE5532. Several later posts continue requesting schematics, circuit diagrams, or component identification for repairs, including a diode reference (D24) and reports of similar failures such as burned-out units or blinking LEDs on power-up.
