I've got the driverack at home, and looking at it now, I did have some compression active, and overeasy on the limiter activated as well. This was on the advice of a sound guy down here... I'm now questioning his merits. Afs is not activated.
The crossover is:
HP 40Hz, BW 24, 0.0 db.
LP 100Hz, LR 12.
Few novice questions, why is the HP the low end (40hz) and LP (100Hz) the top end? The language is counterintuitive...
Also when setting the limiter and you refer to unity on the mixer, that is going to be "0" on the master output of my DJM?
Sounds like you set the limiter correctly, but, if it was some time ago, pays to check.
Always set limiters with no cabs attached.
The final test is if you slide your outputs to max suddenly, and max output voltage for your voltage displacement limit on the amp doesn't change. If it does, it's not set right.
Yes unity would be zero on the master out.
Lots of DJ's love running their mixers above zero, into the red. You should avoid that, as it simply introduces distortion and sounds terrible. If you need more volume, add more cabs!
HP isn't counterintuitive, it only became confused once some people didn't understand what it actually means.
Car audio, and HT manufacturers and users are some examples of those who started using the terms incorrectly in some instances.
High pass actually refers to a filter that only allows frequencies above
a certain cutoff frequency to be directed to the driver(s).
Similarly, LP only allows frequencies below
a certain cutoff frequency to pass.
Neither HP nor LP are vertical lines if you were to see their effect on an SPL chart, because the filters fall off at xdB per octave, depending on the filter design.
So, for subs, you can have a high pass to protect your driver from over excursion, a low pass so you're not trying to reproduce the frequencies your tops/mains are reproducing, then a high pass on your tops/mains so they are freed up to reproduce what they do best because they are not also trying to reproduce lower frequencies...
