Nicola,

Thanks for the tips. I pecking away at this in snatches of time, and I think I am closer.

I am trying to RTA the LR mix for starters. With the RTA mic channel I was having feedback issues which I solved by turning off that channel for the LR mix (duh). I then had to turn up the gain and fader quite a bit to get the gain structure right for the channel. I PAFL’d that channel per your tips. I could then see the RTA level registering and was seeing a pretty flat response with tapering to zero on both ends (what I should see, yes?).

I then got it into GEQ Fader Flip mode but was not seeing that changing the GEQ was having any effect on my pink noise as the RTA output remained static. And that was as far as I got. Riding into work on my bike this morning, it occurred to me that maybe GEQ was toggled off for the LR mix. I will check that next.

Getting closer! …

Once I get over the learning curve, if this is as easy as I think it is, it’s going to rock. I just do sound for my own band, so I am always behind the FOH speakers. RTA-EQing has saved our a**es many a time. Where it’s not as good as a pro soundman, it’s way better than guessing from the stage and can give you a great starting place.
