Just wondered if the following would work, i have other mics but want to run this as a backup, i have an early Church pre (ST20A) and just wondered if the power needs would be met o.k, i.e the available 9v won't blow the mic, or is it a case of that upto 9v is available but the mic will only feed what it requires from this pre? both items are in a drawer at the moment and wondered if this would be a clean way of getting the +30db gain this rather crappy mic usually requires when running line in.
