Obviously there are many preamps on the market which supply phantom on a certain input which also feeds the signal. But, John had these
isolated from each other on Ch.1's insert. Not fully understanding phantom and eveything, I would want to make sure this will not cause any damage
to the EDB-1 by linking the signal source and phantom on Ch.1 itself.
Hi jamison...
I received a note from John Littler of Headway Sound today updating a question I had about plugging an external phantom powered mic into channel 2 via XLR with the phantom power on and then plugging a mono cable into channel 1 for the pickup as to whether it will be a problem...since it has +12volt phantom supplied to it at the same time.

His response is:

I forwarded your suggestion and question about wiring the ''far-end'' of a split cable as well...I'll let you know what the response is.

Hope this contributes to the ongoing experimentation.
