DVX200 audio difference between Xlr input 1 and 2.

Hello experts on DVX200 audio issues.
My almost brand new camera records a thicker (lower frequency) sound from Xlr input 1 and a thinner (higher frequency) sound from Xlr input 2.
All record settings are the same. The same condenser mic in input1 and then in input 2.
The same effect occurs with wireless mics (2 x tx and 1 x Rx on the camera) connected using an Xlr splitter cable into input 1 and input 2.
I would expect the sound to be identical from both inputs but the difference is large. So channel 1 from input 1 is big and booming but channel 2 from input 2 is thin and tinny.
I am not an expert at all so don’t understand what’s happening.

Please help if you can.
Thank you
Alistair
 
If everything for both is physically exactly the same - mic, cables, levels, phantom power (if applicable), and you're not using the splitter in the condenser test - then all that's left is a difference in settings, potential filters being applied in the menu (did you dive in?) or the camera is faulty.

Or possibly a post-production user error if you're listening to the results there.
 
Hi,
I’m not sure if my reply was sent. Still learning how this works.
I’m listening on headphones directly from the recording on the camera.
The menu settings are identical.
The camera is only weeks old.
As you say it could be the camera is faulty which I didn’t want as an option.
Am I correct to expect the same sound quality from both inputs?
Thank you
Alistair
 
It's really mandatory you review the files on a computer instead of through the headphone jack, which could be faulty (and not the entire camera).

Both XLRs should definitely sound the same, but a variety of variables (even down to a pair of broken headphones) may affect the perceived results.
 
Again thank you for helping me.
I’ll try to listen to it on my old MacBook and see what that sounds like. My MacBook Pro is too old for video editing software but I’ll plug in the sdxc and see what I get.
I need an iMac Pro I think.
I have emailed the seller to see what they think as it was bought on June 12.

Hi again,
I listened to the recordings through the MacBook and with headphones and the sound is the same as directly off the camera.
I can’t think what the fault might be other than in the camera itself.
I can only thank you for giving me your time and expertise.
If you think of something else then let me know.
Many regards
Alistair
 
Are you listening to the mixed sound? Or each channel separately?

If you're 100% positive all of your troubleshooting is correct then the last thing to do before trying to exchange/return it would be to contact Panasonic support.

[And there are better choices now for less money than the iMac Pro, which hasn't been updated since 2017.]
 
Hi again,
I recorded on the separate channels 1 & 2. I’ll do as you suggest and contact Panasonic support. You have been most helpful and very kind to bother helping me. It is very much appreciated for sure.
What’s good for final cot Pro x other than the expensive iMac?
Many thanks
Alistair
 
But just checking...did you listen to each channel separately in FCP X? Because they are mixed there by default (if that's what you use), so you could be hearing everything together if you didn't separate them or mute one. (Although you appear to be hearing some kind of difference somewhere so maybe you did.)

As far as computers, it's a complicated question; there would be a lot to discuss depending on your overall knowledge and post-production interests and goals.

There are different configurations and specifications that may be more important to you based on the software you use. Do you ever travel and edit a lot?

If you're just using FCP X with DVX200's files for basic editing, any of the models would work (some with more compromises than others).
 
Hi there,
I don’t have Final Cut Pro x yet as my MacBook Pro won’t support it. Final Cut Pro x is what I want to use.
I just loaded the sdxc to the MacBook pro(2009) and played the recordings on that. One recorded on input 1 on channel 1 and a separate recording on input 2 on channel 2. That was using the condenser mic on each input.
I’m not experienced at all so appreciate your input greatly.

Yes I’ll try and do that tomorrow when I work that out. That would be good if you could hear it for yourself. Can I upload onto this forum?
Alistair
 
No, use Vimeo or Google or a free file-sharing service like WeTransfer (≤ 2GB) and just send the file to yourself and then share the download link they provide here.
 
Good morning,
I managed to download a short file on WEtransfer but I don't know how to transfer that to you.
It's in my email as I sent it to myself as you advised.

So in my opinion, they sound exactly the same. Same levels, same noise, same sound. (Which is a good thing!)

I think the way you're playing them back on your end may be introducing some issues.

If and when you edit your videos in the future, you must learn how to mute the second channel because there is tons of "hiss" in it and it's not even an audio source. You can also mute it by turning the levels down manually on the camera, but be sure to turn them up again when using that input. But if you don't mute it, it mixes with your main audio (which should have an external preamp though too because it's on the noisier side).
