For both Graphs the SPL was attached to the FastTrack Pro and the FastTrack Pro was connected to the receiver. The sub out on the receiver is going in to the 1124P and the 1124P is going to the sub.
Ok, every time I created a set of filters, I all the sudden got a very big dip in my graphs at about 30 to 40 hz. What I started to realize is that my base measurement was never that way. I couldn't create a good graph becaue the 1124 is not adding valleys. I may just be overlooking something.
So what I did was take a reading with the setup above with the IN/OUT button IN but there are no filter settings (all red LEDs are dark) stored in the 1124 and then I took another measurement with the IN/OUT button off (OUT I suppose) so that teh 1124 would not apply filters even if they were set. I would expect them to produce at least somewhat similar readings.
Here are the results with the IN/OUT button off (EQ bypassed)

And with IN/OUT On (EQ on but no filters set)
no eq settings - eq in.jpg
Any help is appreciated
