I'm setting up my monitoring speakers PM0.5n and I'm wondering about the correct wiring of the cable to plug into the combined xlr/jack connector. I couldn't find the manual online, and the manual for the PM0.5d (d instead of n) doesn't seem to answer my question.
I want to use a TRS (jack) connector for each speaker, each one will receive an unbalanced signal. The TRS female connector on the speaker seems to be a three points connector. Should I use Tip/Ring for signal / signal ground and Sleeve as shielding (i.e. chassis ground), or should I use Tip for signal and Sleeve for signal ground? It it's the latter, why are there 3 connectors inside the female jack on the speaker?
Edit: in other words, should I connect the S of the speaker female TRS to chassis (=earth) ground? I'm happy with experimenting and trying 2-3 ways to solder the cable ;-) (The input will be PC/smartphone/iPod/etc..)
