I apologize for this goofy question but I'm confused. My new HK receiver has Left & Right Sub Out jacks. The Hsu VTF MK2 has Low Level Inputs Left & Right. For 2-ch stereo use only, do I need one interconnect with single RCA jack on each end? Or an interconnect with two RCA jacks on each end (for Left & Right on both receiver & the sub)? Thanks for your help.
