Mark Levinson 320s tape loop?

Hi,

I was pondering purchasing a ML320s preamp and was ready to do so, but while reading the online manual, to my dismay, I don't see the way to have it working with a tape loop (to include an EQ), as the older 380 had (or the ref 32 still has).

Anyone can confirm this or tell me how would this work? No matter how hard I try, I can't find any reference at all on the manual mentioning a tape monitor setting.

Thanks!
Brgds, Marcelo
