To make a long story short;

Keeping the XLR cables connected, The more HDMI cables I connect regardless of input or output, the buzz gets louder after 2 cables are connected, and louder after 3. With just 1 connected the buzz is barely noticeable. With nothing connected its VERY quiet (perfect).

Jim at Outlaw gave me directions to do a soft (keeping all info) reset, and a hard reset. Soft didnt work, no to try the hard reset.
