Hi Jean-Pierre
I just finished my 2nd SoundSkulptor Projekt, the EQ573-II. It was a pleasure to build it an everything is running so far quite well, except some cracking noise, whenever i switch the lowcut. It sounds like the crackling in the demo-video on your web site (Build and review of the EQ573), when the on-off switch is used.
Is this behaviour normal, or is this a sign, that i did something not precise enough or wrong?
best regards

This sounds like a reversed cap, electrolytic or tantalum.

Hi Jean-Pierre
I checked the the caps...everything seems to be fine...is there something else, I could check?

Is the noise present when there is no signal in?
When there is a signal, switching the low cut frequency goes through a short mute between frequencies. This is normal.

Hi Jean-Pierre
thank you for your quick reply. No, if ther´s no signal, there´s no crackling. It´s only while stepping through the lowcut, when there´s a signal running through.
Not a big thing...i just wonderd, if did a mistake ;-)
best regards
Stefan
