Behringer GMX 212 Help

[Tubbyspark]

Need Help.

The sound of my Behringer GMX 212 is weird.

It is distorted and sound is mixed with a low pitched sound.

maybe somebody with a simple solution?

[The Dude]

Is the "low pitched sound" there all of the time or only with the signal?

[Jazz P Bass]

Hmmm.

A 'simple' solution.

Take it to a tech?

It's not all the time sometimes worse sometimes less
