Hypex Nilai 500 Monoblock kit build

Today I built my Hypex Nilai 500 Monoblock kits and everything went together well. One thing that concerns me is the Dc Offset on both, one measures .047Vdc and the other measures .076Vdc. This seems a little on the high side for new amps and specially these types. I am running on the High Gain setting.

Has anyone built these kits and what was the DC Offset on your?
