audio track question

Forgive my lack of proper terms as i know very little about audio.
I recorded a clip using a Sennheiser ew 100 G3 evolution wireless eng pack, and a SKM 100 G3 radio microphone.
I noticed on the track that the L channel is ok but the R channel is way over the norm, like the waveform is huge in comparison, I've been able to balance it out ok, but just wondering what causes this and how do I prevent it happening in the future.

Re: audio track question

What device did you record the audio on, and how was the receiver connected to this device?

Re: audio track question

Likely a cable or camera/recorder settings issue..probably has nothing to do with the G3 system itself.
Just use the Left track, it's mono anyway. Most audio or video software has a mono file mode option which allows choosing which side to use. How do you do this? What editing software are you using?
For instance in Sony Vegas, right-clicking the clip/event and choosing "Channels" has the options "Left, Right or Both"

Re: audio track question

the audio was recorded onto a Sony HXR-NX using the wireless reciever with an XLR connection, i havent noticed this before, so was wondering what caused it.

Yeah i solved it by cancelling out the right channel, there's also a balance effect in Premier Pro

Re: audio track question

I would check your camera switch settings as it sounds like one channel may have been on auto with the other on manual or one channel had an attenuator switched on.

I presume you are recording dual left and right from a single input or it may be that you have radio mic on one channel and the camera mic on the other?

lots of variations possible and as I am not hugely familiar with this camera more detail of what and how you had things hooked up would be needed to comment more.

- I'm sure Premier Pro has an option to convert a channel/file to mono, which would be panned to center.
.. A quick Google search produced many PP tutorial hits, frequently mentioned were "Down-mix" and 'File to Mono'. Read the manual.

Re: audio track question

thanks for the replies,
I was aware somewhat about submixing and converting stereo to mono or dual mono, i had done that before, what wasn't clear to me was what result i'd get after converting to dual mono, anyway i'm not that bothered with that because as i said, that was sorted easy enough.

I was more interested in why it happened, I think Gary might be onto something, i remember fiddling with the internal and external audio until i thought i'd turned off the internal mic because i didn't want any handling noise and i only wanted to pick up audio from the radio mic. When i've time i'll test it out to see if this is the case.
thanks everyone for the input.

Re: audio track question

the solution to this was really simple, i had everything set correctly, except i must have turned the R audio dial way up before recording.

So note to self, check and double check the audio levels and dials.

thanks again for the input.
