Thanks so much for the reply Casey - this is most helpful. I'd figured there shouldn't be any harm in doing #3 (apart from increased parts cost and space for components), but wanted to be sure there wasn't a better way of doing it.
I'm at work right now so don't have my mics in front of me. From memory I had my single capsule p48 5024's running at around 5v and they sound quite good to me. I was thinking of pairing up two capsules per channel to try this out, though I do have enough to do three. Now you've given me some clarification I can do some experimenting.?
Being an astrophotographer also, stacking data to increase SNR is something I'm familiar with, though it's interesting to note your assessment of the dB gain in this situation. Having been reading through Vicki Powys' website and a few others touting parallel capsules, including micbooster themselves, it's been suggested there's an approx.? 3dB increase to SNR and 6dB to sensitivity. In micboosters case it really does appear to be just 2 capsules in parallel like other tinkerers do online. I'll be interested to see the outcome with my mics.?
?
Cheers!?
