My friend came across a multi-line intercom box with the microphone (Hamilton Air Model 3001-6 Multi-Lane Intercom, to be exact), and I was thinking about using it as my computer's new microphone. Any thoughts on how I could accomplish this?
in 2016, no sane person should be using an analog mic on a computer. the static can drive people nuts. get a $5 used Band Camp or Guitar Hero USB mic and stick the element at the end of that stick thing.
you're forgetting about the 5-foot run of usually poor cable between an (unbalanced) analog mic and the computer. one great advantage of USB mics is that this is reduced to inches, which makes the signal way cleaner.
