A:AnswerHello, sorry the splitter will not work for this application. This splitter does not have a microphone channel built into it, only left and right stereo audio. This is what is known as a TRS style connection, for a microphone you would need what is known as a TRRS connector which has both stereo audio and microphone channels.
A:AnswerThere are different kinds of splitters. Some will work as they power all outputs, some not as they select a single output. You want the one that powers all outputs.
Good luck finding the right one for you. They exist. I have one.
