I'm about to shoot a documentary-style project with my XH-A1s. It'll be mostly interviews, along with some outdoor location work. I don't have the luxury of working with a mixer. My mic is a Rode NTG-3. I'm interested in hearing people's opinions/experiences/recommendations with using the onboard audio gain control and other on-camera audio functions while shooting. My audio input will be the NTG-3 and poosibly my onboard mic. I can learn a lot of this stuff through trial and error, but understanding a few of the major pitfalls in advance will probably save me some time and trouble. Thanks in advance!
