Ah, OK, you were using the rterm in the conventional EE sense - my bad, I was assuming some special audiophile terminology.

I may have gotten it wrong, but merely accounting for the resistance of a coil in an AC system seems to be a too limited account for assessing the dynamic behavior of the system.
Absolutely!

With cables disconnected from the nc400 itself? Or further along the chain?

And I assume there are no signs of any short around the output terminals? In that case you might indeed have a faulty module. Supply voltage levels are OK?

It could be a faulty short circuit sensor.

sure, an other module works with the same psu

Yes, I dunno why you would think otherwise

For me audiophile terminology can be useful for describing and communicating listening experiences, not for explaining them.

For assessing possible explanations that can account for our observations, we need a more technically substantiated terminology like that from EE which is only one among many technical/scientific languages.

Where my views may deviate from what most seem to express in this forum, is that where EE terminology cannot account for an observation, it does not necessarily mean that the observations is where the flaw or limitation resigns, though it may very well be so.

Exactly

But there might be something wrong with the cables from the power supply to the nc400, so measuring that the supply voltages are ok at the nc400 end might still be a good idea. And a really stupid one, but just in case... have you checked that nAMPON is getting OK connectivity to ground?

Default Advise on chassis

Hey gang, 1st post here and I would like to say Hi to all.

I am a total noob as far as diy audio is concerned and appreciate your input. I found an interesting chassis on ebay and was hoping for some technical input prior to purchase. What do you all think about these chassis po1019 | eBay

The reason I ask is that in the NC400 Figure 2: Preferred Connection diagram it appears that both the xlr 1 pin and the cable shielding are to be grounded to the chassis. Would theses chassis be appropriate.

Thanks, Rob
