dbx 480 makes annoying digital noise!
« on: October 25, 2016, 06:11:36 pm »

Hello everyone, I'm from germany and I hope you guys can help me.

I purchased a 482 and 480 used (here) and I don't know if I'm the problem or that i bought it used.

Everytime, when i connect the outputs of 480 to my system, i hear instantly a very high digital noise. I hope my configuration is wrong or where could this sounding noise could come from?

I hope you have some expierence with this kind of a problem and can help me!

Try connecting to the amp through transformer isolation and see if that helps.

Going to bank one some faulty caps in the power supply, have it serviced but a decent service center.

Wow, thanks a lot. Simple, but it worked!
