Thanks Frank. I was thinking about doing that. Sending the kick, floor tom and bass to Aux 6 then adding some to the mains for flavor.
no, that's not how the aux-fed thing is supposed to work.
the tops and subs are supposed to be balanced and crossed over so that things that need the low end (kick, floor tom, bass) are sent 100% into
both and sound right, while the rest is taken out of the subs entirely.
aux-fed is not about adding in stuff to the tops, it's about
removing stuff from the subs!
The ZLX has a setting on the DSP that lets you select the sub you are using with it. Pretty cool option. Used this setup for the first time last night and everything was sounding great during soundcheck until the kick drum. No matter what I tried on the EQ there was way too much kick drum coming through the mains.
so you're sure you set the tops to where the the lows were taken
out? that's the point of the external sub, to carry the low end and let you take it out of the tops so they have more headroom too.
next time, once you're sure all the boxes are set with the right crossover settings, try running hi-fi music through the system with all EQ shut off everywhere, then adjust the levels of the tops and subs until it sounds right.
if you're gonna do an aux-fed sub thing, set the aux channel out for the subs to 0dB, set the aux send level to 0dB and
leave it there before adjusting the gains on the boxes.
put your low instruments in the sub aux all the way to 0dB, then take the other instruments all the way out of that aux.
at that point you should be able to run every channel EQ however you want and the highs will go where they should and the lows will go where they should.
for the kick, try the classic "rock kick EQ" curve: remove any HPF or LPF, set the lowest EQ band to shelf and boost the low end from like 70 and below, cut it from like 100 to 300, then add a pinch of boost up high, like 2k and up with it set to shelf. you shouldn't need a lot of boost on the high end unless you're in a metal band, but don't be scared to scoop out that flappy, loose low mid. (make a cut, then slide it back and forth with your finger in that 100-300 zone til you find where the flappy, boxy stuff goes away.)
that'll give you a big fat kick that keeps from stressing the low end of the top boxes and still has snap and attack.
