HVX audio question

recorded with a g2 wireless unit the other day, as well as a me-66. they comprised ch. 1 and 2, via the xlr inputs.

my subject (mic'd with the lav) would sometimes walk out of range, creating a nasty static interference. when this happened, i would usually turn the input over to the on board mic - mostly just to save my ears in the monitor.

now i am editing, and i notice a few odd things. first, it seems that the lav audio was still recorded even when i switched the channel over to the on board mic. this audio was moved down to channel 4 though. doesn't bug me, just thought it was curious... is this normal?

second, i hear some minor interference on the shtogun mic's channel during moments when the lav's channel cuts out with static. is it possible for interference to bleed over into another channel?

i'm a DVX vet, but HVX/g2 newb. gotta get this figured out. many more shoots to come...
 
Honestly, those G2 units are widely known to create the audio interference issue. I would suggest shooting with a different lav mic completely, and this should eliminate your problem.

To answer your questions:

Yes, I believe the camera's ability to automatically put that audio onto channel 4 is a normal thing. I guess they did this feature incase the input switches got bumped or something.

Your second question, I think it's completely possible for you to hear interference even on a different channel, but I wouldn't be an expert on the situation.
 
if you are recording DVCPRO50 or HD, the camera always records 4 channels of audio, and two of those channels are always the onboard camera mics, which channel depends on whether you have an external selected.

We use the G2 system at my church, and have experienced static as well. dependng on when you bought them, the frequency spectrum they were originally released in has been supplanted by the re-allocation of spectrum due to HD tv, and now some of those systems are falling in the new public use bands. you have to accept interference from authorized users, and if you interfere, you have to stop use or re-freq your units. Sennheiser will do this (for a fee).
 
honestly, the interference from one channel bleeding over into another is a more serious concern for me. any ideas on that one?
 
One thing that might help is to ensure you are using balanced cables from receiver to your xlr inputs. Some receivers use either 1/4" TRS or even 1/8" mini and if that's the case, be sure your connectors to those are the balanced type. A bad cable, or broken shield on a cable can cause all sorts of problems. I am not directly familiar with the G2. I use either Audio Technica or Shure pro series receivers and never have any issues like that.
