    Hello! This will be my first serious circuit build and I had a question about what to do with the ground.

    Since it's an audio application, I'm assuming that I would just connect all the ground points together, and then string a ground wire from that location to the metal body of the microphone? Do I just connect them all to the ground plug on the XLR cable?

    Hello,

    One of the images is not visible as it links to your local drive on your PC.

    The circuit is probably ment to be used with a phantom power supply.

    All the ground symbols in the schematic should be tied together.

    Hello,

    When you look at this picture from that site:

    you will see a black wire going to the microphone cartridge.
    This is probably the ground connection.
