Is it save to convert XLR to RCA?

All the ic's caused a buzz, but turning off the system and placing them in different positions changed the volume and channel of the buzz.

What happens if you don't change the cabling at all, but you turn the amp off, wait a few minutes, and then turn it on, and you repeat that whole cycle a few times. Does the volume of the buzz on each channel stay the same?

With the ic's connected to the direct inputs (RCA) on the amp no matter which input I chose on the selector the buzz was there. Did not matter as long as the ic's were connected.

When I connected the ic's into the crossover RCA inputs on the amp the noise was there wether I selected the RCA or XLR inputs on the crossover inputs. But with the ic's still connected to the crossover RCA inputs and selecting the direct RCA or xlr selection on the display the buzz went away.

This increases my suspicion that something is defective in the amp's input selection circuit. That's just a guess, though.

It stays the same if all I do is turn off the amp and then turn back on. I may bring another speaker down to test as the problem only surfaced when a new speaker came into the system. Could it be a speaker issue? I know it is passive, but.....

I can't envision a way in which a passive speaker could cause the symptoms you have described. But I guess it is conceivable that a problem involving the front end of the amp, or the interconnect cables to the preamp, could be AFFECTED differently depending on whether an electrostatic speaker or a passive dynamic speaker is being used.

Did you get your buzz solved?? Was hoping to talk about Dude some more too.

Yes, the buzz is gone and all is well!
