They're sending out a replacement harness and a MEC to test fairly soon.
I would guess that the HK(688) center channel is needed as an input in this 10DSP as it has a new feature called Virtual Channel Processing (VCP) for more DSP effects - the 7BMW/7DSP did not need a center channel input as they created a center channel output from the front L/R channels. Otherwise, the 10DSP can be used without the MEC with the HK(688) as the 9-channel outputs can be created with only 6-channel inputs.

The need for the MEC for VCP is specified in the 10DSP manual:
