>>> The mic bias is +3.3 V on the tip. On the KX3, there is also a logic level DC voltage on the ring. This is not as clean as the mic bias and can cause some noise on mics that short those. You can split out those signals with a TRS plug or a stereo-to-mono splitter. See this blog post (from me) for details.
