I started testing with brand new mics (Sennheiser g4 lav &amp; MKE 600) and noticed a distinct &amp; persistent white noise "hiss" sound in my noise floor.

The hiss becomes noticeable once I adjust the gain beyond 5 on the camera for both audio inputs.<BR /><BR /></DIV></DIV><DIV class=""><DIV>I did similar tests on a colleagues c300 and encountered the same issue: I could hear a hiss after increasing the gain beyond 5.
