Hi guys, I did back to back test with a coupler to bypass the unit physically
I had a reasonbly good response with no null without the dsp1124 in the loop. (Sub + L R)
Same test, once I added the DSP there is a null around 85hz and it is sharp. (No filters)
I know this is a timing issue, and I adjusted the subwoofer distance by 1 feet further to compensate, but this didn't help, I even tried adding 2 ft, 2.5 ft, or no addition. The void is still there more or less. Moving the phase knob just moved the null spot
However, after I EQ'd my sub on its own, the graph with sub + L R does not have any nulls anymore. I probably took away my 55hz peak that caused the null together with the L, R. But as I said above, without the BFD I don't have that NULL.
So as long as the EQ'd result was OK, do you think everything is good? It just means I just can't run the unit in bypass mode unless I wanted to listen to a void.
