Thanks for the answers.
if you want or need to experiment with different mics
I’m trying to avoid too much experimentation to save $$$. Using a prosumer microphone designed for cameras seems like a good multi-function solution: plug it into my camera for better sound on my videos, plug it in to the S4 for a bit of VO on my podcast mixes. . . . . but it seems too good to be true.
Kent: If I understand you correctly (and based on my rusty audio production experience) the TSR on the camera mic will require a converter cable or audio interface to make it a balanced outuput before putting it into my S4. If I use a TSR microphone with unbalanced output, I risk all sorts of nasty audio hum and noise. Correct?
