Condenser mic's problem ex1.
 

I have tried both a lavalier (ECM-44B condenser) and a wireless lavalier (Sony UWP-V1), both with fresh batteries and with both I cannot get the audio levels to peak ever. Even if both channels are set to manual and both are audio levels are at 10, it is near impossible to get the audio to peak in the red. If you yell very loud directly into the microphone it will peak sometimes. The audio sounds fine, it just wont peak. It seems like their is little sensitivity. I tried all setups in the camera menu but it doesn't works pergups this is becaus of condenser but +48 volt doesn't works to.

You need to boost the sensitivity in camera's Menu (so called Trim Level): default is -41db, you have to use bigger negative number, e.g., -59db. The camera recording volume should be 5 to 6 for maximum quality.

I'm not sure you can get the camera to really clip. There's AGC and it can't be defeated.
