Guys, here is what is happening when room perfect is set to bypass.
Subwoofer channel all being constant , the only difference is a change in MV on mp50
Measuring channel 4 lfe (in blue), MV-30 on mp50, it shows 74.3db at 40hz
Measuring channel 3 (in green) MV-30, it shows 80.7db at 40hz (centre amplifier muted)
The one in brown shows channel 3 MV-20, it shows 90.8 at 40hz (centre channel amp muted)
Now the increase in volume from -30 to -20 is consistent here on channel 3, ie bass is routed correct and corresponds with the gain settings on master volume
But look at the LFE channel, it is not balanced. Technically the LFE channel should be +10db louder than channel 3, but instead it is 5db louder only. So I believe that +5db is stereo bass routed from mains. But where is that +10db on the LFE track ?
Also u will notice when I switch off RP, it doesn’t attenuate bass below 30hz anymore....
I’m going to try and use the LFE preout channel instead of the auxiliary channels for subs
I believe the auxiliary channels are good for small midbass subs, or boundary woofers that can handle bass up to 800hz...
Definitely not ideal when connecting the deep bass F18 seatons to this channel
Or could it be a firmware issue or bug?
The ULF is definitely missing
