I'm trying to resolve some information. RCA out of my Onkyo to mini. Balanced out of mini to balanced input of inuke 6000. I haven't measured it, but from what I gather
, the 805 will output as much as 7+ vrms from the sub pre out before clipping the output.
When I first hooked this up, I used the 2 volt jumper. With mains calibrated near zero in the Onkyo I needed to boost the sub trim to near its max of +12, and the gain on the iNuke had to be at ~75% (I was trying to avoid maxing it out anywhere).
After switching to the .9 volt jumper I am calibrating with the sub trim around +3 to +5, with the amp gain right at 50%.
As I understand it, doing this means it takes 1.8 Vrms signal input to the minidsp to attain the same max output of 2 Vrms to the amp.
Furthermore, I read that the iNuke needs .71 Vrms into 4 ohms to clip the output with max gain (source: fourth post of this page
With such a high output possibility of the Onkyo, this setting surely increases the liklihood of clipping the minidsp inputs, right?
I'd appreciate input on how to approach any semblance of unity gain with this setup. I can probably get my hands on a true RMS meter if necessary. But with the wisdom floating around this forum and thread, maybe someone can point me right into the light.
