I need to connect one XLR microphone to both my laptop to broadcast online, and to my hifi stereo system with speakers in multiple rooms (including the room with the mic).
I have tried connecting the mic directly to the laptop using an adapter:
And playing back the sound through the laptop's output jack and into the hifi's aux input using another adapter:
The laptop causes a slightly noticeable but very annoying delay in the output from the hifi stereo system.
I somehow need to split (or duplicate) the signal coming from the microphone and feed one end to the laptop and one end to the stereo system's aux input. What is the proper technique to do this?
