Thanks.
You are correct, I am running the Maggies full range from the Sunfire and using one of the two sub out's there as well.
Do you no longer run the Maggies full range and are you now utilizing speaker outs to send the signal to the Rythmik?
Looking at the back of the Rythmik, it seems I have the ability to turn on and off the PEQ or thus utilize the controls on the plate amp and I am guessing this is what your description of settings applies to.
