I want to make an adaptor cable which has a 3.5 mm stereo plug on one end and a male XLR plug on the other end.
The XLR socket (which the cable will plug into) is a microphone input and I want to be able to connect a CD/mp3 player to it via the adaptor cable.
So, how do I wire it? And, do I need to include any components? I know most microphones are between 100 - 600 ohm and speaker outputs are much lower like 8 or 16 ohm. Will I need to add a resistor or whatever to match the mp3 player to mic. input?
TIA
