Edit: It turns out the culprit wasn't the amp, but the brand new speakon cables I picked up from Monoprice. The connector looks like a Neutrik, but for whatever reason there's some slack when placed into the amp. Even when it's plugged in, there's about 1/16 to 1/8 movement. That slight movement was the cause. I tried the speakon cable that came with the amp (which isn't a Neutrik type), it snapped into place and didn't move one iota.
I'm really disappointed in the new cables. They are thick, heavy and look to be durable. But they don't play well with the Carvin. Funny thing...they play together nicely with the Acoustic Image amp.
