I have three NC252MP modules I want to make a 6 channel amp out of for my Surround and Atmos speakers. Currently working on the case.
For wiring, however, is it really as simple as both the speaker binding posts and the balanced input connectors wire directly to the boards and the power inlet also hooks directly to the boards? No extra boards or input buffers necessary?
I would most likely be using pre-made cables from Ghent along with a custom case. And supply my own XLR and Speaker binding posts. Along with power button and 12v trigger.
I am fairly good with small electrical wiring. Maybe not so much with in-depth wiring diagram/schematics. But from my looking around for the last few weeks, these modules are fairly straightforward right?

looks easy to wire up.
mains power, output to speaker and audio in.
it will be about 1vrms input sensitivity so a pre amp will be needed for some sources.
line level sources should be fine.

It will be connected to an HTP-1 Pre/pro processor, which allows for setting a custom Input Sensitivity value between 1-4V. I should be fine without a preamp then, right?
The Ghent Audio cables I would be getting come with the Enable Jumper, so should be good. Thanks!
4 or six wires to the 10 pin box connector depending on if you are going single ended or balanced. Then you need to wire up the enable pin to 5V. I used the aux supply on the smaller box connector to power the enable pin.
I did a frequency response measurement driving the amp directly and it looks great. Unlike the Icepower 125AXS2 which needs a low output Z buffer to the input of that amp.
I'm using a NC122MP with IanCanada's rPi based boards and ropieee as a network streamer. Work and sounds quite good.

Thanks! Now I need to see if I can get a DIY Audio case with the appropriate rear panel cutouts. I don't have a CAD diagram, but I am assuming if I just ask for a panel with (6) XLR cutouts for Neutrik connectors, (6) Speaker Binding Post cutouts and a Power Cable cutout it should be doable, no?
I plan on having a 12v Trigger so my Pre/pro can power on/off the amp. Will I run into power on "pops" from the speakers or should it not be an issue?
I don't have any thumps or pops from my NC122MP. you do hear a relay on board click, but the speakers are silent, unlike with my Naim Nait.
