RTA page 1 MAX and RANGE are just so you get a good display and will not have any effect on the EQ. You want to select MAX so that the display never hits the top, and you want to set the RANGE so that there will be something to see even during quiet parts of the music. Your settings will depend on the gain of the amps and sensitivity of the speakers, but on my rig MAX = -20, and RANGE = 60 works.
(MAX is negative, because it is dB down from the reference level. In other words, -10 is louder than -20).
If you want to roll off highs at 1 dB/oct hit the ROOM CORR button. Most people like this, but you have your choice.
