ok, i realise this may be some orders of magnitude below the specs of most stuff that is posted/designed/discussed here, but please bear with me, i'm only just starting out...
anyways, for my ambisonic project, i've decided to get at least something working using very cheap electret capsules. i've ordered 5 different kinds (which are also all quite similar, but nevermind), and realise i still need some kind of interface between the capsules and my preamps.
the spec sheets for the capsules i'm getting state operating voltage of 1.5 - 2V.
i want to avoid battery power, imo that's a crap solution... especially as i'm lucky enough to have this thing:
SCV pre-amp set
which can provide 15V phantom power, or i can take +/-15V straight from it's module supply rails (+15/0/-15).
i also understand that the performance of electret capsules can be enhanced by using a higher supply voltage (ie, higher SPL capacity and better SNR). how far is it feasible to push the capsules before they stop working?
bah, sorry for all these questions in one go... and this isn't even half of what i still need to understand
any help would be much appreciated.
(btw, my goal for this part of my project isn't necessarilty audiophile precision, more just to get something thrown together to get my ambisonic rig basically working... the high quality stuff can come later - if it works).
