At the risk of bringing up an elementary design topic...
I'm needing to build a simple, passive, in-line, balanced high pass (low cut) filter to use with a TLM103.
Something similar to the Shure A15HP (w/ a 100Hz roll-off):

I imagine this circuit would use series caps on the hot and cold of the balanced line - thereby preventing phantom power from passing through. So, I assume the filter would need to be inserted post-preamp (line level).
Does anyone have a simple schematic for something like this? Or, perhaps there is a circuit that will pass phantom?
Thanks for your help!
