Most of today’s cameras have flexible input trimming. So, I’m sure you can use a wide variety of input levels. I am just used to the old broadcast definitions of line and mic level. From the thread that Bruce provided, they say the F4 tone generator is not very usable to set reference levels to camera. I was trying to kill two birds with one stone. I might be better off with a used Sound Devices 552 for twice the money. Otherwise, maybe a small separate recorder to go with my mixer. It’s just for backup in case the camera has an audio problem (which recently happened). Thanks for your replies.
