I am using the canon xf105 to shoot some interviews. We have 1 lav that is given to the talent and also would like to use the internal microphones on the camera to capture what the interviewer is saying (just for content purposes). Whenever I plug a mic into an xlr input or into the 1/8" mic input, it seems to cut off the internal microphone(s) completely. Is this inevitable? Or is there any way around this.
It should work. I normally use a Rode NTG2 external mike through the XLR port on channel 1 and the internal mike on channel two on my XF105.
The mike selection switch is set to "MIC +48V" and "EXT" for channel 1 and "Line" and "INT" for channel 2. Make sure the switch is set to "INT" for the channel where you want the internal mike - otherwise it will be looking for an external mike.
