QU-32 to Camera Sound Difference

Recording an octet with piano would be spread around at least somewhat in the stereo field so only one cable would have to make it sound different in the camera. With one channel this is looking like the culprit to me.

…Only if the piano input or inputs were panned on the mix.
He said all the sends to mix 7 - 8 were panned straight up center that would the outputs 7-8 the same with
no stereo image/field.

It’s a long shot but possible that a mic or two are wired with pin 2 & 3 swapped at one end and when those channels would be combined with input channels from the same source would get some strange phase cancellation.
If that were the case though I would think you should be hearing that at the board.

@MikeC

true in theory

now their set up may be different, but in ours there is always some mike leakage so time delays would create differences in the two channels so if you only listened to one channel not both together you would not hear the same thing.

do we know that the mikes were actually all panned center and somebody else did not pan them to appear in the stereo field in relation to where they were on stage? doing that and using both xlr inputs just seems more logical to me than only using one side of the stereo pair on mix78 out.

Yes mic leakage can cause phase issues but going by his information all channels panned to center so there is no stereo image being created.

Yes try using both outputs to feed the camera and set the camera to record in stereo even though with the mix sends all panned to center it will be dual mono. Maybe the camera is doing something strange when set to mono audio recording.

Maybe yet there is a chance that when monitoring the mix at the board what there hearing in the headphones is being influenced by some other mix source.

@deltoran

Maybe post a short clip of board recorded audio from mix 7 - 8 and a clip of the same
audio pulled from the camera recording.
Or post them somewhere and let up know the links.

Also just to double check, are you taking the mix audio out directly from the mix outs
on the board or from a matrix output?

@MikeC

You are right.
I was stuck on thinking how I always do stereo and keep forgetting that AH does it differently.

For sure they should just connect both cables and see if the problem goes away.

If not then we at least have limited the problem some.
Pretty sure he said mix78 out but a matrix would change things if they are doing that.

You do realize the main mix pan and the pan on each stereo mix are independent from
one another.

As for panning itself, for a live mix I don’t anything too extreme as in wide panning if any at all depending on the system layout and the audience seating.

For recording your dealing with a more controlled listening space.

@MikeC

The church only uses mono.

When I record stereo there is no panning needed as everything is already ‘panned’ by their physical location.
I rarely fake it by building a stereo field from individual mono tracks.

At what level/mix are you panning at?
To record in stereo with a stereo image you would still need to pan the needed inputs
to somewhat represent their physical location from the viewer perspective, if that’s what your going after.

@MikeC

You are confusing me.
I don’t pan them at all as they are already ‘panned’ due to the physical position.
My first choice is xy coincident miking although midside works well too.
After that it depends on the source.
Wider spaced AB or ABC if there is a hole in the middle.
Sometimes close spaced but only if the angle and space is computed not arbitrarily using one of the named versions that only works well for the originator and their room not a general solution like so many people use without thinking further.

sengpiel has many more useful stereo charts
and many many more other pages about audio and related

another good stereo info site

And whenever possible a second backup recording done simultaneously.

You are confusing me. I don’t pan them at all as they are already ‘panned’ due to the physical position.

Well you did not exactly make it clear you were using room mics for recording.
What do you send them to for recording?

@MikeC

Sorry about that. I meant for my use I use my own mike set up to record.

What gets used depends on the situation.
On site for a small group I would often send them to a small digital recorder with xy, or else they go direct to my PC and DAW at home if I were doing more than 2 tracks.

If needed I could rent a multitrack digital to record on site for a large event but that is not my main focus.
