I guess some outboard phantom boxes DO use coupling caps but they really shouldn't be required for any "decent preamp". Either there's an input transformer, or existing caps in the preamp that can withstand the phantom rail.

OTOH, really low end preamps might have cheeze-ball input caps, but I haven't run into them myself. Behringers and other cheap Chinese stuff aren't in my realm.

Power-One (and others) make a nifty open frame linear supply rated 48VDC at 0.5A. One of those modules will power at LEAST 35 mics under absolute worst case conditions.

I still have a few Power-Ones left from a "close out deal" I found awhile back. Ping me off-list if anyone is interested.
