Default Basic question?

Is a single NC400 amp module mono or stereo? Info sheets on their website do not mention.

Curious, what is achieved by "keep the lead between pin 1 and chassis as short and straight as possible?"

Minimizing inductance (and induction). Not sure it really makes much difference, but it's just sound practice.

Does the nc400 have some kind of dc-protection circuit?
I am playing with the idea of bypassing the output caps on my Oppo BDP-105, that I have directly connected to my nCore monoblocks.
But they say there is a little bit of dc when turning the Oppo on-off, that is why they added output caps.

No, any DC offset on the input gets amplified. I suggest leaving the caps in place.

I apologize if this might be a remedial question, but can a second xlr input be safely wired to the primary xlr input in a nCore 400 build?

I need two inputs on the amp; neither source would be in use at the same time.

Thank you for your help.

No, you can never wye two outputs into one input (neither balanced or unbalanced) the first output will see the second output as a dead short. You will need some sort of a switching arrangement or summing network.

Was afraid of that. Thanks for the input (no pun intended!)
