As my Pioneer VSX-1124 doesn't EQ subs differently I decided to only use one output on the AVR and then split the signal at the miniDSP. I had thought about using both outputs on the AVR when I encountered this "auto on" problem but then thought that I'd have to purchase the alternate miniDSP plugin.
Anyhow, as stated, the Y adapter didn't seem to do much. I went from a -5.0dB setting pre Y adapter to a -5.5dB setting with the Y adapter (MCACC).
When I get a chance I am going to take an SPL meter reading with the adapter and without the adapter (same AVR setting and gain knob setting) to see if the Y adapter was a complete waste of money as I suspect it will be.
After seeing that the AVR minimally adjusted the subwoofer I put both gain knobs down to about 12 o'clock. I re-ran MCACC and I got -3.5dB which I then bumped up to +0.5dB. This still didn't kick the subs "on" from "auto" until I was in the teens on the volume control.
Last night I experimented around with the volume control set to -30dB. I incrementally increased the sub (in the AVR) by increments of 0.5dB up from +0.5dB. I got to +3.0dB before I saw the green light on the subs. +3.0dB seemed to be the sweet spot as +2.5dB didn't seem to do the job. That setting though would ultimately be 6.5dB "HOT" as I see it. I think that is a bit much. If the AVR needs to be set to +3.0dB for the subs to kick on then I'm going to grab the SPL meter and adjust the gain myself.
So if I go that route and want to "gain match" the subs at the MLP I need to adjust gain knob to until I get 75dB at the MLP correct? What I would rather do though is gain match the subs so that both of their knobs are relatively similar. So I think I might go that route instead. After all... not many sit at the MLP except for mama anyway... my favorite spot is right up next to the sub as it servers as my only end table... although of late I have noticed the V1500 doesn't like anything on it! Probably unlike the sealed variant
On a side note... watch Thor Dark World last night with the subs 3dB hot and OMG!!!! Wow!!! Anyone thinking these V1500's don't equate with CHEST pound come on over! I was saying wow all evening!
