Problem with wireless mic levels using Shure Mic and Lumix GH3

[justinroffmarsh]

Hi there

I'm shooting video with my GH-3 and recording audio using a wireless (lavalier) Shure mic. I'm connecting the mic receiver to the camera using a 6.5mm mono to 3.5mm stereo cable.

The mic transmitter has three gain settings, I've tested 0db (line, I guess) and the 'mic' setting.

The former produces a lot of hiss but the latter seems to result in the mic being massively oversensitive -- it isn't possible to move without the mic picking up loud rumble.

Can anyone suggest the ideal path forward here?
