Hi Alexander,

The 5 pin isn't the problem since the hiss comes and goes and disappears with increasing gain, but as Mike suggests, it's always good to keep the 5 pin connector clean. Sweat, rain and Coca-Cola ends up in there as the transmitters go through various users. Alcohol on a thinned down Q-Tip works pretty well or cotton on a toothpick. Don't flood the connector. We try to seal them but it is not 100% effective. You may have to blow a strand or two of lint out after you finish.

 

I suspect instability (oscillation) in the mic gain stage when the gain is below 20, particularly since it "stabilizes" sometimes when you unplug the lavaliere.

Best Regards,

Larry Fisher
