I get distortion when adjusting the channel gains on my mixer
My knowledge of mixers dates back to the pre-computer days of pure analogue sound so I know nothing about digital mixers.
I took a brief look at the specs and didn't understand most of them and I reckon it would take an uninitiated young person a year to become thoroughly familiar with what it can do and two years for everyone else. I feel one problem could be inadvertently leaving something, some process that had been previously used running in the background when attempting something new.
All equipment produces distortion and every component, lead and connection produces noise but quality gear is built so it is inaudible to the human ear, hopefully.
Distortion is principally caused by a poor signal to noise ratio, by poor quality or faulty equipment, by component mismatch, by overloaded audio stages or by excessive compression or clipping of the signal, either deliberately or accidentally or received interference from other equipment.
People who work a lot with audio equipment tend to instinctively know the type and cause of distortion when they hear it and can take steps to cure it or minimise it.
Some distortion is useful, the fuzz-box that made so many guitarists famous, for instance, is pure overload distortion...
