From the manual:
"The amp performance is optimized for 8 and 4 ohm loads. Lowerimpedances can usually be driven with some precautions to avoidextreme volume levels. The amp is protected against overloads, andif pushed too hard, you may hear harsh breakup on peaks and/or agradual power reduction accompanied by the Power LED “winking”to indicate thermal protection. Reduce Master somewhat to mitigatethese behaviors."

That made my day! I think the CC should have spelled it that way too..
