Hooking Up a Sub to a Rane MP2 Mixer

I have a Rane MP2 mixer, and JBL Eon G2 Powered Speakers.

What would be the best way to hook up a sub to it.

Ideally, I would like to run the sub directly from the mixer so I have control of it's volume. However, I do not see a seperate volume control for a 2nd output.

Can my mixer handle a sub hooked up to it? Or do I need to just run it from the output of the eon?

Either way would have the same effect. For ease of usage, I would simply "jump" the signal output from Eon to the input of your powered sub (or amplifier and then to your sub). I have run Eons and a sub this way many times.

The sub is powered...

What I have been doing is running the output from the eon to the input on the sub.

The problem with this is that I do not have control over the sub volume from my mixer.

After looking a little closer at the Rane mp2...I noticed a few things...

There is the main output "house" (which I can easily adjust the volume of). This is where I hook up my eons to.

There there is also an "aux" output. However, the volume control is located under the mixer, and it seems like you need a screw driver or something to adjust it.

I suppose my two most realistic options would be to run it off the eon, or from the aux of the mixer. Neither one is ideal.

Has anyone dealt with a similar issue?

I was wondering the same thing as Bob:

1) If there is a built-in crossover on the sub, why aren't you using it?
2) If there isn't a built-in crossover on the sub, why aren't you buying an external crossover?
 
Okay . . . first the disclaimer.

I am ANYTHING BUT an expert when it comes to this sort of thing. Technical stuff is not my forte'. However, there were some technical people who advised me on the manner I have used for the past two years with great results. Also, this particular configuration does not address the issue of controlling the volume from the MP2. And this may not be of any help whatsoever . . . but I thought I would at least offer what works for me.

In one of my systems . . . I use an MP2 Rane mixer with a BBE Sonic Maximizer. I have two Ramsa speakers with a 250 watt power amp and a Mackie 1501 Powered Sub. I use a Y JACK (Monster Brand) that is a 1/4 inch male (coming out of the BBE) to 2 female 1/4 inch connectors. One goes to the powered sub - while the other goes to the power amp. Thus splitting the signal. Fortunately the Mackie's have a separate knob on the back to control the output volume of the sub.

If I didn't have the BBE, this would work just as effectively coming directly out of the back of the MP2.

I am certain there are many ways of doing this . . . but this particular configuration works best for me. I hope that helps.

steve...
how do you go from an EON to the input of an amplifier then to a sub ?
The Eon has a "pass through" circuit. You can use a "Y" adaptor as Larry has done, and run two lines out, but the pass through method will do the same thing (and you don't have to keep track of an adaptor). You take the output from the Eon, which is a signal level, and run it into either the input of a powered sub, or into an amplifier and the output of that amplifier into a passive sub.

I always go Eon first, and then the sub, even though you could do it the other way. My reasoning is: if components or cables fail, I want my "mains" to be closest to the audio source. I can live without the sub, if I have to. I will have far more problems if I lose my mids and highs.

Steve,

currently i use the mono sub out of my denon mixer to the mono in on my powered sub. I have the option to do stereo in w/ 2 inputs on the sub. If i decide to run from the output of my EONS, is it better to run it stereo and run a cable from each EON?

Steve,

It's highly unlikely you would lose both tops at the same time, so it shouldn't be a worry. Second, and more importatly IMHO is that you're running your mains full range with a subwoofer...why? You'll likely find the sound to be cleaner and clearer using the top cabinets as mid/hi cabinets and let the sub do it's job of covering the bottom octaves.

Edited to add: Does the top cabinets perhaps have a crossover switch to cut the lows out of their signal? If so, then routing it either way is ok.

Skovy-

Could you please identify this powered sub that does not have its own volume (gain) control? I'm sorry but I've been a real gearhead for a lot of years and have never come across a powered sub that doesn't have its own volume control ... unless it was only intended for home stereo use.

I believe you'll find very little difference, if any, running both channels into the sub. The summed mono you're using now is actually better than the shortcut I'm using, which is taking a single channel's signal and connecting an active sub to it. In theory, I lose a channel. In reality, the way music is mixed down to stereo channels, the low frequencies are almost always in the middle of the stereo mix, so not having a sub on one channel is going to work just fine.

Neither the Yorkville sub I use, nor the Eons have a built-in electronic crossover. It's true that separating more fully to a true two-way system would probably yield cleaner results. The closest thing I can do, short of bringing an electronic crossover, is: attenuate the bass on the Eon (Eon has bass and treble pots) down, allowing the Yorkville to handle more of the bass, and giving the Eon more headroom.

I answered the thread in the manner in which the question was posed "how do you add a sub", and not "how do you set up a two-way system".

Regarding the MP2 and MP4 mixers, if you do not have a 2nd output (booth out, or sub out, or even "light" out), you cannot control the sub level from the mixer, you'll have to go over to the sub and turn the gains on it.

Unless using an external crossover, in which case you have separate levels for the mains and the subs.

Also, am I the only one who questions the use of a BBE Sonic Maximizer with a powered sub? I thought using a Sonic Maximizer with any powered cabinet was just asking for trouble.

I'm sorry, but I have never heard anything about the use of a powered system with a BBE Sonic Maximizer. What is the concern about that?

Yes! Well, maybe! :) Honestly, I have never heard there be any question about this before.

I have used BBE's religeously for more than a dozen years. For the past three years I have used BBE's with my Mackie powered subs (probably more than 300 performances) without ever experiencing a problem.

I'd be interested to hear if there is some sort of manufacturer's opinion regarding this.

I have powered JBL Eons, and subs with a BBE Sonic Maximizer in my system. Have never had a problem either.

Larry,

Mackie strongly recommends NOT using those little black distortion inducing boxes called sonic enhancers...

It's spring cleaning time! Take out the garbage and get a good constant q eq...it's SO much better!
