If you met to ask if the 6000 would work without a legacy adapter through a DPP44 switch, the answer is yes (but you do have to have power to port one of the DPP44)
The setup is a Dpp Lnb no Dpp44 switch also no Dp recievers The 6000 would not work without an adapter but check this out , i used a
Dpp44 switch power inserter in place of Dp adapter for legacy recievers " i have plenty of them since i do not use them for Dpp44 switch" and it worked!
I knew those power inserters would come in handy one day
