Hi everyone! I'm new here. Basically i'm developing my final project and i have a big doubt:
I have 2 microphones AKG C417 which need a power supply as any condenser microphone. I have too a phantom power supply AKG B29L that works with a 9V battery, and my idea is to integrate o recreate this circuit into my board, but when i opened the B29L what i found was a complex circuit, with many capacitors and resistors, and actually looks very different with respect you can find on the internet about "Phantom Power Supply Interfaces".
So the question is, i need to feed my 2 microphones, i already have a regulated power supply of +/-9 V on my board, i attach the diagram of that, and i want to use it for my microphones, but i need a good interface from my source to the microphones, and from the microphones to the pre-amplifier.
I hope i have been clear with you about what i need.
Thanks
Best regards
