Maybe a bit of an increase to the speaker trims, knocking off a few dB of sub-out. will do the trick.
That's another possibility. Increasing the other speaker's level trims and moving reference down from 0dB on the master volume to something less would create a bit more headroom in the LFE chain.
I did some additional testing yesterday and found that you can also create some additional headroom in the MiniDSP for gain from filters with the input or output trims as long as you're not clipping the input.
In my test first I lower level for the input by 6dB in the GUI.Note that the input level meters don't read dB
. A 6dB reduction show up as -12.
Then I created a 6dB boost at 40Hz.
That restored the amplitude of the output (per the level meters in the GUI).
Here's what shows up on the scope of the input vs. output.
No clipping. Also, the behavior is the same if you reduce the output level trim by 6dB and leave the input level trim a 0.
