Many thanks to @rogs for sharing the OPIC.43 design. I was looking a bias supply I could build on protoboard and decided to build the whole thing.
I paired it with a JLI TSC-1 and I think the result is fantastic. I'm using it as an overhead for drums.
I previously retrofitted 5 of these BM700 style bodies and Jules' OPA Alice boards to use on toms. These ZRAMO mics came with 25mm capsules (I swapped in JLI 2555 for a couple of them). I used 220pF caps to pad the output to better work with my audio interface.
I compared the output level of OPIC/TSC-1 with the electret mics and found the output at the lowest voltage to be right in between the electret mic with and without the 220pF cap. I'm using it as an overhead so I don't need quite the same level of padding.
Is this the best way to pad the output? Can you pad LDCs with a cap in the same way as an electret?
