How do you solve "popping" when source switching?

I have a Rotel RSP 1068 processor running Innersound Eros MKII speakers through its own bass amp and cross-over and a Proton AA2120 amp for the panels and if I hit mute, or swith from CD to Video 1 and so-on I get a "pop" in my speakers and it happens with both the bass and panels so I know it is not an amp causing this, I sent put my Rotel for service because I thought it was the culprit. A fellow Agon member let me use hos old Carver pre-amp so I could enjoy music and such while mine is out and his does the same thing, so now I wonder what if anything I can do about it.
I am running everything into a Monster 2000 surge/conditioner. The only thing I can be sure of is it had to do with my speakers being very efficient (96db), are there any thoughts or pointers you guys can tell me so I can get rid of this problem, I doubt it is dangerous to the speakers but it is very annoying so please help!
thanks again all in advance...Chad

will the intensity/volume of the "pop" be less if you turn down the volume knob to zero when you source switch & put into mute?
that's something you could try.

No the popping is constant at any volume and is not louder or quieter at diffrent volumes, infact if I turn it all the way down, when it hits zero it pops because I guess it kicks it in mute...but thanks anyway.

It's the digital lock causing the pop. Does it only do it when you switch from CD to Video or mute the processor? Does it only do it on the digital ins? There may be a software update that will fix it from Rotel. If you have direct input access on the remote try and change inputs that way and see what happens.

When I hook it up to the direct inputs (multi-channel bypass) I do not get popping when I switch channels or CD tracks, I am having Rotel do a firmware up-grade so I hope when it comes back it is all resolved. I am in the meantime asking incase it still does it so I can be prepared for a fix..thanks again!

This is an obvious question but I have to ask, do you have a mute button on your pre-amp or one on your amplifer. Because if I forget to turn them on when switching the selector I get that same pop. Try lowering the music (Which Sucks) but what else can you do. This pop can be very loud which can damage the driver
