it is low frequency. thanks

I've had my iFi for 8 months now and love it. But for the past week, I've been getting intermittant super-loud feedback/humming. It sounds like the speakers are going to blow out. I've adjusted the volume and the sub-woofer, but usually have to turn the power off. I thought it was a problem with my iPod, but they work fine with headphones. Has anyone experienced this problem? Thanks..
