@Broken-Form - if you want the douts - you want one for each 4 x stereo channels and 1 for every 4 x mono channels module

and remember there are 2 versions:

3hp Douts - 8 3.5mm outputs
original Douts - 8 3.5mm outs and 6 1/4" outs - can also be used for 6 way format conversion

I will buy Them assembled and want 1 mono and 1 stereo so that means i need 2 douts?
