The 3808 can assign different crossovers for each channel (but it does not have 50 hz \:\( ) I have my m80's set to 60 hz, my vp150 set to 80 hz, my surrounds set to 100 hz, and lfe set to 100 hz. These were someones reccomendations (jakewash maybe????). They actually reccmonded putting the m80's to 50 hz but I did not have that option.

And the neat thing is I just now pulled all that info up from my computer by typing in the ip address of my 3808 and looking at the settings from IE
