I'm using the AT897 (it's a $250 shotgun mic that supports phantom power or battery).
I can hear hiss when when I crank the audio level up. Obviously it's not as noticeable if the mic is closer to the subject and the audio level is set to a lower level.
I'm not sure if this is the normal performance of the camera when it exceeds the noise floor. I assume the mic itself is not to blame (the hiss exists even with nothing plugged in) and I know the cabling is not causing any problems since I'm using high end mogami cables with top of the line connectors. The XLR gain is set to off (up +12db creates more noise as expected). Both phantom and battery power give similar results.
Is this just the result of the XH-A1 not being able to amp the signal straight from the mic to high levels without introducing noise? Would I be able to get rid of this hiss and record audio at higher levels if I ran the mic through a pre-amp and switched my xh-a1 input to take line in?
I'm not looking to fix the hiss in post (which I've had to do so far). I'm also not looking for an inexpensive hack that only slightly fixes the problem. I want to do things right at the time of production and am willing to do what it takes to get professional results.
