Default 7.1 passive pre amplifier

Hello,
Ifound a nice 8 channel attenuator on the web, see following link
http://www.dact.com/html/press_release__8-gang_ct2.html
And i was wondering if somebody has constructed, or planned to constructed a nice 8 channel preamplifier based on passlab pre amplifier. If so I would intressed to have some advice.
Another think I'm wondering about is how do I manage to have a selector between two different 5.1 or 7.1 input and 3 normal 2channels input.
Best reagrds
Christopher

do you want to build a passive preamp, or an active one?



in both cases, as an input selector, you'll also need a 8 channel selector switch

there's no way i'd ever get something like that wired up
right. I can't even get a 1 input 1 output BOZ right!!
I couldn't imagine 8 channels!!!

wouldn't you need multichannel processing in the preamp too?

seems like a lot of work if you just want a mulitchannel attenuator.

or am i missing something (most likely!)

The goal is too be able to use it as a pre-amp fro a SACD player and a DVD-AUdio/Video player. So no digital processing at all. Just the pre-amp part.
Hi-End multi channel pre-amp
Just have trouble to find a input selector, any ideas out there?
