My organization recently purchased the Sony HDR cx700v camera in hopes of recording our events. We have an XLR to 3.5mm cable so we can plug into press boxes so we can bring the audio feed right into the camera.
The problem is, there seems to be some sort of Auto Volume feature, where if there is a silent part of the feed, after 1-2 seconds the camera will try and overcompensate and raise the volume of feed, which is silent, and the result is a loud, annoying hiss. It basically makes using a direct feed for the audio useless as any break from the action results in the horrible hissing.
I've looked up and down the menu of settings on the camera and the only thing I can find remotely relevant is there is a "Micref Level" with the options for "Normal" or "Low". Default was "Normal", but I've also tried "Low", and all it does is minorly lower the volume of the hissing (as well as everything else), as it's still there after 1-2 seconds of silence.
I'm kind of at a loss for what to do. This was an expensive camcorder that other than this automatic volume behavior works great. It's gotten to the point though that I can't use the direct audio feed, and have to just rely on what the built-in microphones pick up from the event, which gives it sort of an amateur feel, but is better than having the annoying hissing going on during silence.
Can anyone help me with this? Is there something I'm overlooking? Anything I can do?
thanks very much
