TacT Millennium upgrade mk2->mk3 digital crossover question

Hello,

I have a question regarding the old TacT Millennium mk3 (upgraded from mk2)

I am under the impression that quite a few mk2 got upgraded to mk3 using a upgrade kit supplied by Lyngdorf containing a DSP board, that replaced the mk2 board, making it possible to use DSP features and digital crossover, since there where 8 speaker terminals. 

However, I have noticed that the mk2 amps came with hefty jumper bars across the speaker terminals on the output boards. The factory made mk3 didn't have jumper bars. So, I am wondering whether people upgrading fra mk2 to mk3 missed out on the digital crossover feature?
