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). Does anyone know 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!)
I did the same thing - re-wiring the stock cable to XLR. Pinout is:
L+ pin 1
L- pin 2
R+ pin 3
R- pin 4
I just cut the 1/4" plug off then used a DMM to ID each wire. Yes, the central pin is positive on the earcup side.
Your amp has separate outputs for 4 vs 8 ohm? If so, I guess the higher one is more appropriate since the 500's are >> than 8 ohms.
