I've been investigating some wall patch panels from an old FSR system install that's been replaced with a Soundweb/Crestron setup.
Old system signal flow was as follows:
Wall patches->Patchbay->Rack mixer->Patchbay->FSR->Patchbay->Amp
All of the Mic input jacks on the wall patch panels
have a 1.6k-Ohm resistor between pins 2 and 3.
I am wondering what the rationale behind this might be?
