AA QD5-MKII crackling issue

Former Member

Hi all,
This is my first post here. I joined because I am having an issue with my American Audio QD5-MKII mixer, which I noticed the last days.
Whenever I am raising or lowering the volume through the master volume knob I am having some loud crackling noises from the one speaker. The crackling is worse when I am changing the volume rapidly and after some repetitions of the move it turns better - while still noticeable.
I did some troubleshooting with the cables and speakers and found out that it is indeed the mixer's problem (btw I'm using the balanced outputs). I also opened up the unit (my warranty ends in 20 days and I am currently abroad so I gave it a go) but, not being a expert, I couldn't see anything unusual.

Any ideas?

Did you try cleaning out any dust in the mixer when you opened it? If its only the Master knob and only when yuo turn it it can be the potentiometer needs replacement. A tech should be able to replace it for you.
