AV subwoofer output and 7071A

As stated in 7071A's user manual, the av processor's subwoofer output should not be connected to lfe input of the 7071A, because included filters will conflict with av's filters.

Copy from the manual:

<<If there is a subwoofer channel output on the decoder it should NOT be connected to the subwoofer's "LFE IN" input since the processing within an 
analogue decoder will conflict with the filtering in the subwoofer.>>

In a complex system setup, there isn't the option to set the speakers as "large" and let the sub do the crossovers.

I was wondering if the "sum in" mode, from the dip switches, is a good solution for removing the subwoofer filters.

I did a lot of search, but i couldn't find any information about what exactly the "sum in" mode does (for the included filters at 85 or 120 Hz), except from the obvious chain connection from a master sub to the slave sub's. Of course, this means that no more filtering should be applied from the slave sub's, but i couldn't find this clearly mentioned anywhere.

Thank you for your help..
