Mark Levinson No. 39 act as a preamp?

i just recently purchase a used Mark Levinson No.39 from a local buyer. I don't have a manual for the unit. I heard that the ML 39 can be use as a preamp so that i can plug my scd-1 to my levinson. Is it true that the no.39 can act as a preamp? If so do anyone know how/setting for it?

Thanks,
John
