Audio combo jack vs headphone/earphone with mic and speaker connector

2016-11-14, 1:59 AM

How is the microphone jack on the front panel wired? I was told this jack works as Microphone and LINE IN. Is the jack a 3-pole stereo jack or 4-pole jack? If it is 4-pole, does it comply with CTIA standard wiring (Ring2 is common and Sleeve is microphone)?

I'm assuming it's your M900 Tiny 10FM?   According to the detailed specs, it has:   "one microphone (stereo, 3.5mm), one headphone / microphone combo jack (stereo, 3.5mm)".   My limited understanding of the (4-pole) combo jack is that there's one common standard that headphone/mic combos, and adapters that break it out to 2x 3-pole connectors (one for mic, one for headphone/speakers), use.   That is what is used here.
