How has the Behringer DCX helped your system?

[Inertia]

Just wondering what the DCX has done for your setup? After using one would you say that it is a necessary piece of equipment? I don't have one yet but am thinking about buying one in the future.

 

[annunaki]

I would say yes. I am not done tuning but with 15 minutes of time...

My response in room went from this:

To this:

so what does this mean?

Are you serious?

If you are, that is my plotted room response (for bass) graph before using the DCX and after.

It is critical if you want full control over both the mains and sub(s). It's extensive crossover parameters allow transparent/seamless transition from the mains to the subs(you need to run both mains and subs through the DCX). With a neutral speaker, the DCX also allows critical adjustments that will optimize perceived sound quality to the listener, such as a shelf filter on the highs to slowly graduate a slight attenuation on the treble(shown to be critical in perceptual research) and to fine tune the baffle step compensation step to your particulate room/placement (BSC can never be optimal with a passive xover since it can only be tuned by the designer for one particular situation; but a device like the DCX allows you to fine tune it to your particular application using a low shelving filter - and this makes a huge difference to realism of mid-range). You can also adjust the 'tightness' of bass sound using the DCX to reshape the bass roll-off. You can make a ported sound exactly like a sealed, etc.

I am serious, when you guys show this stuff its like greek to me and I just glaze over it. now that I have my own DCX coming for my kappa build i think I need to start learning about this stuff.

I also should say I learn by seeing and hearing people explain things to me some how reading manuals is difficult for me..

this my not be the right place to go over all this stuff.. but it seemed as good as any when i asked.

Talk about sounding like Greek. Thanks for the info Chris, but can you put it in laymans's terms?

 

[j_garcia]

In layman's terms, it means you have total control of the sound.

Now for simple step by step set-up instructions in the same layman terms and then I'll integrate my fronts through the DCX

amen brother!!

Download the remote install program to get a feel for what you can do.

Simply put it allows you to clean up your music and movies.

It corrects flaws in your speakers, room and speaker placement.

It can also be used to make your speakers sound bright, warm. Etc.

Sounds like a great tool............. IF you know how to use it.

Which is not beyond anyone on this forum, as long as they are willing to try - even when things get hard.

Does the DCX help with a 5.1 or 7.1 system or just with 2.1?

 

[Guiria]

I would say yes. I am not done tuning but with 15 minutes of time...

My response in room went from this:

To this:

This looks like some good EQ which the DCX certainly can do. If all you are doing is EQ on a sub however, the DCX seems like overkill to me. A BFD will do that job for less than 1/2 the cost.

what is a BFD??? when my friends call me BFD they usually mean big F'n dork

It does much more than that! I can have my low pass filter run through this piece, if I had a vented enclosure, I could set the infrasonic frequency. Any of the slopes are infinitely adjustable too. As WmAx stated it is phenomenal at integrating a sub into the mains or vice versa. It is the ultimate integration tool.

Here is a more "tweaked" response graph since I had more time.

Each DCX has 3 inputs and 6 outputs. As such, you need 2 DCX units to do multi-channel. The DCX units can be connected in a daisy chain so that only one is the controller/master unit, and the additional units act as channel expanders to add channels. This simplifies use, as you only use one of the devices for all configuration.

The BFD has only 2 inputs and far less power. The DCX can do just about anything to your response curve. The BFD requires a lot more work to do the same things. Both work with REW, but for me dynamic EQ is the greatest alluring attribute of the DCX. This means I can change my eq with volume levels.

So if I really want to crank it I can protect my drivers. Or if I want to go low and give up some volume I can do that too.
