2 supply rails in NAIT 5 (preamp section) & NAC 112

Posted by: Hans 67 on 04 January 2003

In the old preamps 1 supply rail is used for the phono stage and the other supply rail is used for the rest (or am I wrong here?). But there is no phono stage in the NAIT 5 and the NAC 112.

What is powered by which supply rail?

I do not think that it is seperated in left and right (or am I wrong again?).

If you power the NAIT 5 or the NAC 112 from a power amp and you disconnect the link plug:

Which part of the preamplifier does not work anymore?

I think this answers also the 1st question.

If the NAIT 5 or the NAC 112 is powering the stageline:

from which of the 2 rails (inside the NAIT 5 and/or NAC 112) is it powering the stageline?

Or is it powering the 2 rails of the stageline from the 2 rails in the preamp?

By the way:

how are the 2 rails in the stageline split?

And if you have some extra time:

how is this all with the more expensive preamps of NAIM?
