Summary: I purchased a factory refurbished HK 3490 for my vacation house at the beach. When it arrived in May 2013, I attached speakers and tried to use it. The unit immediately displayed the message "Voltage Protect, Check DSP" and stopped operating. This happened several times. I call HK service and the technician suggested that I had a short in a speaker wire and explained how to test. I performed the test, replaced a speaker wire and the unit performed for two days.
