So, someone messed up at our highschool, and now we have a combination of Pro-Intercom belt packs and headsets, and a combination of ClearCom packs and headsets. I have no clue how it happened, but so we don't have to drop a grand on new equipment, can the two be intermixed with each other?
Specifically: the 2W XLR-3 line interfaces are compatible, and separately, the headset A4M jacks are also interchangeable; both of those are industry standard interfaces (within 5-10%; you might need to tweak levels and sidetone a little).
