Need help fast - Unbalanced Preamp to Balanced Amp

I have a NAD C162 Preamp that has two pairs of outputs that can go to multiple amps.

I have a balanced amp with ONLY XLR inputs (obviously).

What is the best way to connect the preamp to the amp? Is the best way to configure this setup to use both right outputs from the preamp (via Y splitter cable?) to the balanced amp to maintain voltage (and do the same with both left outputs at the pre)? Not a techy type of dude so any help would be appreciated.
