Do you think it would be worth picking up a 31 band EQ on the cheap just for use ringing out the room and then transfer the settings for the offending frequencies to the Dx38?
There is a used unit at B&H for under $100. Was tempting. Since I am not spending my own money I can't just pull the trigger. Seems like doing the setup with a parametric EQ hidden in the menus would be a lot more effort.
I may have a friend with one that I can just borrow.
Not to be "picky" but how were you planning on coming up with the "numbers" to enter into the DSP?
By looking at the front panel of graphic and "hoping" that the silk screened number on the graphic are remotely correct?
Good luck with that.
It appears as if you keep trying your best to do it the wrong way and somehow hoping you will get lucky enough to somehow get close enough?
That is a long shot at best.
Aligning a sound system is not a "guessing game". At least to do it right.
And if feedback is is a cocnern-then a good alignment (not "ringing out" the room) is the best starting point.
