Krell Showcase 7 Pre Pro Configure Problems

Thank you Aux for responding. The mistake I was making all along was misinterpreting what OSD meant. I was under the impression that OSD meant the screen on the unit itself. The seller did tell me it had to be configured via the OSD. My bad. I emailed Krell and got a very detailed explanation, now knowing it had to be connected to a display. The unit works fine but I must admit that I`m frustrated trying to set this thing up for Home Theater. I`m trying to set it up for 5.1. It`s way more complicated than I anticipated. I may just turn around and resell it. Again, Thank You Sir

Yes, my whole intent going in was to use this as a audio only component. I knew the video part of the Showcase was outdated. That`s probably why I skipped over the video portion of the included printed manual. Luckily my display had a composite connection. I really only use the Preamp mode (XLR input from external DAC) and the 5.1 analog inputs (Aux 1) from my Oppo player. Maybe more connections will follow. Also to complicate things further, I had to re-configure the Oppo . I know that I`m just going through the "learning curve" of the Showcase. It`s just frustrating, that`s all. I thank you for your help and insight. I appreciate it. I`ll try to be patient with this Beast. I like Krell having had 2 Amps over the years. Plus the price was right on the Showcase.  Thank you muchly,
