Hi guys, I have a cheap lav mic with a 1/8" cable that isn't producing any audio when plugged in to the XT200. I played with the mic gain settings in the camera's menu, but still no help. The built-in mic works fine but obviously would like improved audio quality. Does this camera require a powered microphone to be used instead? Anything I'm missing something as far as settings go? Does something need to be turned 'on'? I'm new to the camera game and upgraded from my iPhone, which obviously was working with this mic w/o any problem. Thanks in advance!
