Infinity IRS Betas Make Loud Noise When On

You need to list your entire system.

I have an Aragon 28k preamp. I have an Emotiva XPR2 amplifier. I am doing all the hook ups without the mid-high panels connected because I don't want them to get shorted out, so I am only hooking up the base towers for now. I don't have anything else plugged in. I am using Monster cable interconnects and using the stock servo wires that came with the towers originally. Any help would be greatly appreciated.

When you hit the power button on the xover, do you hear a pop or clicking type of noise? If that's the case, just turn the xover on first.

I'm not sure about this, buy you may need to have the entire speaker system on and connected whenever you use it, and not just some of it like you are doing now. That would definitely be in the manual.

Not familiar with Betas but it's probably similar to the RS1Bs that I run. The servo unit is phase dependent, the phase has to be be correct. It sounds like the amp or pre-amp might be inverting the phase. You need to find that out and then connect accordingly. I have a couple of servo controllers but they are a pain to run. Your servo controller is going into protect mode. You are lucky the early models would just blow. They often have hum. One of my units worked fine and then started humming out of the blue so that is when I scraped it (saved it for the next guy).
I have run my system without the servo controller, just using a crossover and it works fine at the levels I normally use. Those systems are state of the art and finicky. Trouble shooting is difficult and not much fun.

When I hit the power button on the xover, I hear both. As soon as the green light comes on the xover, it pops really loud and it goes into protection mode.
