Subwoofer Level Control for Dummies

OK, I am obviously learning impaired in my old age. I read a couple of the self help articles and am still left with a couple of questions. I know I'm slow, so please don't flame me...anyway I am using the auto config/wizard with the following gear and settings;

2X JBL JRX 100 (125's) stereo
2X JBL JRX 100 (118S) subs in stereo
A pair of QSC 2450's to power the mains and subs
DBX Driverack PA with RTA mic
Live mode
Auto EQ using RTA mic

I really have two questions. Can I use the \"Gain\" setup as explained in one of the self help articles, and still utilize the auto setup wizard? If not, how can I adjust the level of the subs after finishing the auto setup wizard? Thanx a million....

    The wizard will set the x-over filter types and point. These settings are changable and adjustable. The wizard (some guy) used BW at the cross point, most around these parts would use a LR. I would lower the point to 100 - 100 also. But, any or all the above should work well for you.
    If you need to boost the subs, you can increase the gain in the x-over section (or reduce the gain of the tops).
    Oh, after setting up the x-over and making adjustments, ree-check the gain structure and limiter settings.

    If you could be a bit more specific when asking questions..Like, are you speaking about the \"welcome..start here\" article? Dra's truncated reply didn't say that we usually use BW filters for the sub rolloff..for their fast rolloff, and the better protection they afford the subs... Discussed here...

    Once the wizard is done you NEED to edit the set up... set the HPF, and the crossover point between the subs and tops... this is where the crossover type and slope are also edited...Once this is done set the system ballance using the method listed above, or using the DRPA's crossover gain control. The method listed in the above article is the simplest and garners good results... More advanced users may want to incorporate the amp sensitivity into the equation, but I have not experienced a significant difference in noise or performance using the articles method.
