The link above doesn't explain the EQ section very well (IMO), so I'm sure I'll have some additional questions ....
I ordered Floyd Toole's Sound Reproduction ... I'm hoping it will help shore up my theory foundation
That is a fantastic book, though admittedly I have not yet finished it.
It's fairly easy to add filters into the 1124p, and you can PM or email me if you need assistance doing so. However, here are the steps:
Use the dial to make all adjustments below.
1) Turn the dial to the number 4 or 5 and hit the "filter mode" button to ensure it's PA (PEQ).
2) Hit "filter select" and start with number 1 (the first filter).
3) Hit "frequency" and set it accordingly, followed by "fine" to fine tune adjust said frequency (for example, if it's 40+2 in the filter list, you'd select 40Hz for the frequency, then hit the "fine" button and set it to +2).
4) Hit "gain" and set how many dB's you want to cut or boost.
5) Hit "bandwidth" and set it accordingly, then move onto step 2 again and run through step 5. You'll repeat this for each filter, but be sure to change the "filter select" number to the next in line (2, 3, 4, 5, etc) when adding a new filter.
6) Hit the "store" button twice to save your settings once all filters have been added.
7) Re-measure and see how close the actual response is to the predicted (it should basically be spot on). You can then fine tune from there, perhaps adjusting the gain a little bit using the filters you already added.
