I intend to rewire my stock HE-500 cable (silver) to XLR and build a "pigtail" for connection to a speaker amp (like the HE-6 cable). Could you please tell me the correct pin allocations for the XLR? Am I correct in assuming that the conductor connected to the central pin in the earcup connector is positive, and should be connected to the red speaker output?
Finally, I assume that I should use the 8 Ohm taps rather than the 4 Ohm ones......
The speaker amp in question is an 18W PSE 300B Opera Consonance Reference 5.5 Mk.II (see avatar!)
P.S. Yes to the bolded question. Use a multimeter to keep track of the wire types. Once you've identified the wire you can keep track by marking the wire using masking tape or something similar.
