I'm designing an analog audio circuit, but I'm not sure how to wire the audio plug from my mp3 player into my circuit. It's a standard TRS plug. So far what I've learned about TRS connectors can be summarized in this table:
I want to be able to handle all 3 cases (Mono, Balanced Mono and Stereo). I also want to treat the tip and ring signals separately (in other words, I'll have a separate circuit for each signal). I'll be applying some active filters to these signals (simple - something I've learned in school), but right now I'm stuck because I don't know how to prepare these signals for inputting into op amps.

Mono Jack Stereo Jack Stereo Jack
(Mono signal) (Balanced Mono Signal) (Stereo Signal)
Tip +ve +ve Left
Ring -ve -ve Right
