Dcx 2496

[pjoseph]

I think I will be asking for this for my upcoming birthday, but I have a few questions.

First current setup.
Receiver is Marantz SR 4001, also have a Behringer EP2500, and PS3 for movies and games.
5 Boston Cube speakers I forget which ones, and a JL13 inch woofer in a ported box that I made thanks to all the info and help on this forum.

My question is how would I tie the DCX in this setup, would I only be able to use it for my sub by putting it between the receiver sub-out and the behringer EP25000? is there a way i could use it for my main speakers as well.

Thanks

To ty your mains into it, you would likely need a separate two channel amplifier for them.

BTW, also consider the less expensive miniDSP. Here's my thoughts on it:

I personally am more comfortable with something like the miniDSP then Behringer stuff. It's small and can be mounted in a box with a couple tripath amps for an amazing active crossover system.

I recall that the MiniDSP also has a lower measured noise floor than the DCX. I don't know about the tripaths though. I think i've seen some measurements which show some high frequency issues (same with ICEPower too btw). I think the hypex are the best designed class d amps out there based on what I've read.

The responses above were correct in that you would need a separate amplifier to take advantage of a DCX on your mains.

It is a fantastic unit in it's own right however for a subwoofer if not a bit of overkill.

Hi, Yes you can certainly use the Behringer DCX2496. And as stated already you will need the additional amps to power in bi-amp mode.

As to the question about noise levels/floors etc. I use the DCX2496 on my mastering system and I use a Rotel 1077, 7, channel, Icepowered based power amp with it. NO high frequency issues and I have Ribbon tweeters which will accurately reproduce any such issues.

I have experimented and tried the Panasonic XR series, the Trends 10, the HLLY-90, my own mono blocks based on the ICEpower 250 and traditional power supplies (non switching) and in comparison, the Icepower based amplifiers do not have any issues with high frequencies or noise.

I run the Main left, Main right and SUb woofer into the A,B, and C inputs on the DCX2496 and I have configured the 1&2 outputs as the Low/High for the left channel, the 3&4 as the Low/High of the right channel and I have experimented and run the 5th output as the Sub out ( not required with my full range mains).

The DCX2496 is extremely flexible and allows you to sum the low frequencies from the left, right and sub inputs at whatever frequency cut off that you what and send them all to the configured Sub output channel if you want.

The DCX2496 also has Parametric EQ, time delays, phase control that you can use to correct any issues on your sub woofer. EQ to smooth the freq response (real in the room response), a time delay to adjust for time alignment (dependant on where you place it relative to your mains) and a phase adjustment to both make an invertion if the absolute phase output of the sub speaker is out 180 deg, as well as make fine adjustment if for some reason the sub has a phase mismatch with the mains.

It is a bit of a learning curve for a non-technician, however it is well worth it and I would suggest that you get a good technician hap you through it if you are not a technician.

Hope this helps?

Cheers,

Tom

I've heard that touted a bit of late, but have yet to see measurements to back it up. The chips in the DCX have better specs so I doubt it. It's probably because most people don't give the DCX the levels it requires (it's pro heritage y'know) to get optimum SNR.

For the price and the application of a sub xover/EQ/delay the MiniDSP is a ripper and great value.

FWIW, I own both.

You may want to translate ripper for the American crowd. Not sure everyone here speaks Australian.

This is a very useful thread. I took the plunge and replaced my old analog DBX crossover with the Behringer DCX running three-way to my for Ripole subs and hybrid electrostat mains. In addition to the positive views I read in this thread, I had also read some mixed reviews in other forums for the DCX so I was a bit anxious about the decision. But I have to say that my system sounds fantastic now that I've got it tweaked in with the EQ's and the drivers time-sync'd. This thing is wonderful!
