Thank you, glad you liked the video. Great question, I would say it depends on the environment you are shooting and the distance the microphone is to the subject. I generally keep it at 0db when recording dialogue in an interior room, increasing the gain may increase the low frequency room noise. But again depends on the environment, and what sound you are recording.
My MARK IV started reverting to Auto every time it goes on sleep mode, it never happened before, do you have any idea or tips on how to solve it? Thanks (and for this video as well!)
