Obviously, the NAD has preamp outputs, which allows you to use it as a preamp to drive external power amplifiers.
But, does it have power amp inputs on the back? If so, then you can use it as a power amp.
hint...if you had to remove a link to use the pre-outs, it most likely does.
I post this not to be a wise-***, buy simply because you're in the best position to provide the best answer by simply looking at it, not to mention you have the manual.
