MONO OUT for a single (1) sub with (2) stereo tops. Aux 6? Not same as crossover idea. Just MONO.
I often use my system with just one subwoofer and two tops running in stereo. I probably do this more than I use two subs. The presonus board I already sold for the mackie had 3 main outs, 2 for left/right and a mono out that I used for my sub. They both actually have their own gain control. Can we use aux 6 to mirror all main signals and use the channel fader as a type of gain? And then if I raise or lower the main volume the aux channel 6 moves relative to the main signal, but still retains the balance I set with the aux 6 fader.
I know this is similar to someone's else suggestion about using aux 6 as a kind of crossover signal for subs, I personally don't need this, my subs have built in crossovers, and I am not opposed to rolling of highs with the geq's if I have too. This post is specifically aimed at a Mono signal for subs.
AS long as we don't looose the aux for all of us with bigger bands then yeah good Idea
I use aux6 set to post fader for sub mix. Works fantastic! The only downfall is you lose a monitor mix. Most bands don't need 6 sends anyway. Bring on a 24 channel though!! Much needed!
Jon Balslev: most modern subs with built in crossover have a link out to the top speakers. (Two in two out and the sub plays the low freq from both channels). Why dont you use that connection model?
That connection model doesnt allow real time adjustment of the speaker management during a gig, especially while walking around with an iPad.....
Tweaking the crossover and related settings 'remotely' can be a powerful solution.

What are you talking about all at 0db. All what? Auxs? Or all channels to that aux? Im assuming all channels to the aux set to 0. That would work to a point. But it's better to have the aux 6 still linked to the master fader channel. With this workaround you would still have to raise and lower the aux 6 independent of the master. And also the suggested idea would automatically send the main mix to the aux 6 out. No fooling around with the aux other than to set an initial gain level. This way the only controls used would be master and aux 6 level. In other words mains and mono.
Very good workaround. and I think it would work.

Set aux6 as post-fade and set them all 0 dB, and you're done. If its a real sub-range cabinet (crossed at 100Hz or under) you better only set the sends for channels which are having this part, eg. kick, bass, floortom, etc. This setup is quite common also on bigger pa systems, channels like vocals, brass, and other instruments basically hi-passed are kept away from the PA subs simply by the routing.

Yep good idea
Great idea. Summed mono is important for subs.
