The capsule needs no current to operate as it does not have a FET.
That was not clear in your post.
The question is, does it have to have a DC voltage of 0 across the capacitor, or will having 1 volt affect the bias enough to impact the response?
The equivalent voltage of an electret mic is close to 100V, so 1V is negligible. t should be less than a fraction of dB.
