XLR Left and Right Output Mismatched

[guitar_person]

Hey everyone.

 

I recently noticed that my Helix is outputting different levels through the left and right channels. 
I've always run a stereo setup so I thought maybe it was the way the amp settings were so I compensated with adjusting their individual volumes. I usually run 2 amps which are hard panned.
However, I recently had to setup and run a mono system so that I could have 1 signal go to the mixing desk and another signal go to my own foldback. It was here that I found the signal from the left channel is far quieter than the right channel. 

 

I had the two xlr's plugged into the helix but only plugged one into the foldback at a time. This way I could check that the signal was just being doubled onto the other channel and ready for the gig. It was here that I realised that the signal level was different.

 

To make sure it wasn't an effect on a patch I loaded a blank patch and tested the dry signal going straight through the helix and into the foldback. This had the same result.

This has me kind of stumped. I can compensate it to make do however left and right channel should be the same. I want to avoid backing everything up and doing a factory reset. I always find doing this stuffs up with my midi programming and snapshots.

 

Has anyone experienced this before?

No - and i've checked it.

Are there any other possible explanations - have you reversed the cables?

It's the easiest way to be sure it's the Helix.

If it is your Helix, you have a problem that should be checked.

Thanks for the comment.

I have reversed the cables and it was the same outcome. That was the first thing I did to be sure that they were both working. I uncoiled them to make sure there wasn't any impedance issues and jiggled them around a bit. No success unfortunately

I may have to take it to a tech. Might try a full factory reset first though :(

I have the same issue. Did you find a fix to it? Thx

Hi,

 

You have posted your question to a thread that has been quietly sleeping for 5 years. 
 

The OP has only ever made 2 comments, both of which were in here, with the final one ending with:- “Might try a full factory reset first though”.

 

The regular response to anything unusual happening with your Helix hardware is to perform a factory reset. Have you done a factory reset on your device? If not do it now!

 

Hope this helps/makes sense.

Does it occur with a completely balnk path? Just guitar. No amp, effect or anything else in the path. If it does, then you have an issue. If it doesn’t happen and both paths are equal, then start taking the effects out one at a time until it’s equal on both channels. That’s the effect you need to change either entirely or just the parameters.

Let me guess.... it's that mono bug again?  Just a wild guess?!

 

Power on the Helix.  Plug something into the right jack.  Unplug.  Then plug a cable into the left/mono jack.  Now left/mono jack is working correctly, right? 

 

(for those who are unaware: there's this Helix bug where the left/mono jack doesn't combine left+right into one properly (proven fact on 2 Helixes I own) and potentially does other funny things as well.  The workaround for me to get left/mono to work properly is the procedure described above).
