Say I have a Allen and Heath ZED-22fx mixing board and just ordered 2 powered 18" seismic audio sub-woofers. Well the Mixing Board does not have any sub outs or sliders. It has 3 Aux outs and 2 main outs. So can i run the subs out of a aux out 3 the monitors out of aux out 1 and 2 and the main out of the mains? Or will sub frequencies not travel through the aux out? How should I hook up the sub-woofers? All the help will be appreciated thanks in advance!


Here is the mixer:

Your link did not work for me, but it appears that at least one of the subs has a low pass filter.  that is important when looking at subs and not using a processor.

Yes the sub freq will go through an aux out.  So you can hook the subs to an aux out.  I would use a POST output, that way the sub level will "follow" the fader levels.

(1)Every aux will pass whatever you assign to it.
(2)Without a crossover your top boxes will see a full-range signal. This may or may not be ideal.
(3) If the board only has 3 aux, what will you use for effects?

How do I change it so that the aux is post mix instead of pre?

I work at a summer camp and the chapel is in the dinning hall which is a big area the has alot of reverb, so for right now we don't need effect since adding more reverb would be horrible, what other effect would i need?
There is a 3 aux and 1 fx channel. The fx channel is controlled by a seperate yellow knob on each of the channels so there is no need for a 4th channel right? And so are you saying that I should have a crossover so that the main speakers are just high and mids and the subs are just low end? The main speakers are dual 12"ers with a 1.5" coil im pretty sure im not there right now so idk.
will this crossover work fine?:

Would i hook up aux 3(sub) to the crossover and then from the cross over to the snake(since the speaker is plugged into the snake). and then same with mains? The board has built in effects btw so even if i want verb(don't want it) then i could send it through the fx channel. Here is the link to the board again:

You said you had an effects unit-so that is where his question came from.

You didn't say what tops/full range cabinets you have-so there is no way to guess whether or not you need a processor of some sorts (analog or digital)

Whether or not you drive the subs off an aux is hard to say what may be best.  Depending on the operational skills, it is often bettern NOT to run the subs on an aux.

Having gear and hooking it up is one thing-making it sound good is often quite another.

This stuff is not "plug and play".

So would you recommend that I have the camp sell the mixer board and buy one with sub channels? The mains are some off brand like PRO or something like that, they are passive speakers. Thats all i know sorry.

"Subs" are both sub-woofers and sub-groups.  Sub-groups on a mixing console have nothing to do with sub-woofers as such.  One might feed a signal to a sub-woofer from a sub-group, but the common term "sub" is only a bit of a coincidence.  A sub-group handles combining signals from multiple channels for common control or processing.  A sub-woofer reproduces the lower part of the sound spectrum for the listeners.  Both are commonly referred to as "subs", but they are different animals.

When buying a console you need to look in terms of various functionality.

FIRST  Number of channels needed-plus some for spares-don't forget effects returns-playback channels etc.

Next -Number of auxs needed-Monitors-effects-subs-(tweeters if needed)-recording etc.

Then how much control in the eq section do you need.

Sub groups will usually 'come along" as you progress up the "needs" scale.

The console has to function as you need it.

As the old saying goes, The wrong tool at a great price is still the wrong tool.

Okay yeah I didn't choose the sound board... but I understand what you are saying... but I simply need to know what would be the best way to hook up the subs with this board, and should i use a crossover(they do have the LPF (Low Pass Filter) - 45Hz - 800Hz built in to them) if i use a crossover how should i run it. Mono Mains, left main would run both main and right main would run subs?

[duane massey]

In answer to your basic question, still need to know what your top boxes are (powered or passive), but:

Considering your apparent lack of pro-level skills (no offense intended), get a simple crossover, go from the l/r outs of the mixer into the XR, lo outs to the subs, hi outs to the tops, start off with crossover set at 100hz. Engage the HPF if the unit has one. If you have access to someone with experience get their help on-site (even if it costs a bit for one visit), it will be worth it.
