Matt, I was messing around with distance settings last night and I'm confused.
Is it possible that the distance settings in an AVR and the distance settings on the minidsp (I have the 2x4) work in opposite ways?
What I mean is, with my AVR if I increase the distance setting the sound gets to my ears quicker. The opposite seems to be true for the minidsp.
So here is what I did.
1. I took a frequency sweep of my subs and mains in their current settings.
2. I decreased the distance settings for my subs on my AVR by 8'5" (the same as 7.5 ms or close to it). The initial distance on the avr settings was 13' and I changed it to 4' 7" Doing this will make the sound from the subs get to my ears later.
3. I increased the delay in my minidsp that controls the subs by 7.5 ms (it was at 0).
4. I took another frequency sweep.
5. I expected the 2 sweeps to match, they did not.
6. So, I tried it the other way. I increased the AVR sub distance by 8' 5" from it's initial setting, so I went from 13' to 21' 5".
7. I I left the minidsp at 7.5 ms.
8. I took another frequency sweep and now it matched up exactly with my first measurement when the avr was at 13' and the minidsp was at 0.
This makes me think the avr uses distance settings in the opposite way that the minidsp uses distance settings??
If so, then adding delay on the mini means increasing the time it takes for the sub output to get to my ears and adding delay to the avr means decreasing the time it takes for the sub output to get to my ears??
I'm 100% on the AVR end of it, I know for sure that higher distance means sound gets to me quicker, it's the mini (and the inuke dsp for that matter) that I'm not sure about.
