Behringer DCX2496 digital X-over

It does.



Sure.



If you have use for both, sure.



The DEQ is a mastering/remastering equaliser, the DCX is a Crossover with the addition of equalisation to correct for driver imperfection. So, they have very different purposes and are complementary in purpose.



There is a little article on my yahoo group:

Suggested target curves and setup techniques for Pro Audio Digital Equalisers in home systems for Room correction and general system EQ

Yahoo groups requires you to register before you can access this, nothing to do with me. When Yahoo allowed non-members to access files they where open to all.

There are also a number of other articles by a variety of authors in the Files section of this group, may be worth snooping around a little.

It is the same thing, except the second suggestion with pin 1 unconnected leaves the input floating. I found this better in many cases as often both DCX/DEQ and the transport have "earth".


Many thanks Kuei - your advise is always valuable...

Your question was to Kuei - but I can not help saying - "Who knows - but try use Deoderant for safety sake"

DCX's & 6 more ch's soon

Ugh this is going to be a long post.
Probably my first real post here, but I have some damage done at lansingheritage.org, so I'm not new to going off deep on the browser for audio posts. Or car posts. Agh.
I will try to introduce my self well, I hope I do! But first-

This thread Byteboy started here has re-sparked an interest in me I have had since I first saw (and imagined) the JBL DSC-280 in the late 90's.
I think I hve read all of the posts, I konw I have spent several hours on this one thread here, front to back. Some history-

IIRC in '98-'99 $4-5K US for the 20/48 JBL Pro DSC-280 was the price to play. (there was a -260 as well) But oh so far we have come! YES! Tis a good time to be alive!
Lots of great data and ideas for a active XO nOOb like me starting out in this thread- My deepest and most profound thanks to all DCX users, wonderers and modders that have contributed!
Any So. Cal. readers here, please feel free to PM me so we can share ideas. (read=so you can help me set up my DCX's)
This tickles a fevered, anticipated desire I have held for so long; to do away with my DIY passive xo's, get 6 more amp ch's, and really get serious. I shrug away all the money on Solen or pricier caps and parts express chokes.
But I'm getting ahead of myself. My existing system:
__________________________________________________________________________
Sources/recorders-
Meridian 588 CDP- (24 bit, balanced analog outs on XLR; S/PDIF on RCA)
Yamaha T-80 FM tuner (DX'er)
Kenwood KT-7550 FM tuner w/ Bill Ammons mods (Strong locals)
Tascam CDRW-5000 (I burns me copies to help steal money from millionare artists)

Gain/switching-
Classe' CP-60 preamp (Balanced analog in/out on XLR, (unused) surround and (used) tape loops on unbalanced RCA, lots of jammin maple OK-A juice for the DCX analog in)
trivia fact- did you know the CP-60 has over 120 electrolytic caps among the 2 chassis?
The main board has a grave site look with its rows and rows of redundant caps. SQ is there, what a great gainer she is. Love her!

Amplification-
Crown Studio Reference 1 w/ FMX pip XLR in/out module (over-rated, way over-priced, but imposible to wound, deform, melt, explode...130V rails (!)
I have used several high-end amps that sound better and some actually survived. Others have not been so lucky, and I paid dearly for their untimely deaths)

Speakers-
JBL 4343 (4-way with external custom 1st order passives & custom 4-Ch. binding posts; (2405 UHF, 2420 HF, 2121/2122 MF, 2231A LF)

Power-
Various PCB-loaded 1200V paper/oil caps in AC load center from poles to neutral
2-pole 30A breaker into
Powerstat 0-260V 8kVA variac (down from 248VAC to 220VAC) into
Topaz 5kVA 220/120 ultra-isolator into
40' of 3-8 Carol to hospital outlets in listening room (noise is *reported* >80dB down compared to the wall)

Cables:
(3) 1M Harmonic Technology (HT) TruthLink on XLR
(1) 2M (HT) TruthLink on RCA
(3) 1M (HT) AC-11 power cords
(1) Analysis Plus Oval9 speaker cable w/ T1 spades
____________________________________________________________________________

Questions- lots of questions....Thoughts....Ramblings....
1- I will use the Crown Ref 1 for LF duty with (2) DCX's, 1 DCX per channel with 2 outputs unused. What about amplification for my 6 missing channels? stereo MF, HF, UHF....Behringer A500 or Alesis RA500? Seems like the same amps with $20 better cosmetics than the Alesis, which I prefer. What do you guys think? Anyone using these? Would say (3) Crown CE-1000 be worth twice the cost when all drivers are 96-112 dB sensitive? I don't see needing much power up top at all, (new rules) just transparency, timbre, and dynamic control, as always. Gawd $550 US for (3) stereo amps that look so simple inside with very few parts, I bet they are like cheap Linn/Meridian/Naim amps that cost $3K US or more with cheaper build. They remind me of my old Jim Strickland Acoustat TNT-200 as well. Very few parts! Simple, direct signal paths.

2- will EACH DCX use more or less internal rescourses running my 1x4 scenario vs. (1) DCX running a 2x6 setup? I would think less since it's 4 vs. 6 ch's, but 2 passbands vs. 1 passband, IDK if passbands are rescource pigs compared to LF or HF filters. Process headroom is a must, I dont want to be pushed against any performance celing or "run out" anywhere in the system. If need be, I'll save and *sigh* look at driverack 480 some more.

3- How easy is is to integrate and use 2 DCX with RS-232 interface? I'd hate to have to adjust each DCX seperately for stereo- In the GUI can you make adjustments to both DCX simotaneously if using each as a 1x4?

X- I have to keep telling myself that my pre-concieved notion of power requirement has to be corrected- new rules. With no passive cap and coil sacks to "drive" before the drivers, even a piddly 50W RMS on a DCX'd (JBL 2420 16 Ohm compression driver for instance, rated 35W RMS, 112 dB sensativity) should do fine. JBL Pro and Crown reminds us that it is lack of power that burns out drivers. Clips kill. I found out the hard way on a DIY class A disaster and paid a dear price for NOS replacement D16R2421 diaphrams. I'm hard on stuff I guess.

I'll cut it short because I'm sure as days pass I will have a clearer picture of what significant questions to ask.

Thanks for reading my post! I hope to be among the DCX users in 8-channel wonderment ASAP.
It really makes me shiver every time I think about a dream like this realized. No more solder, No more tweaked leads from yet another XO hack job(s) Thanks again ya all!
 
do you guys think that there will be a new model from behringer??
shoudl i be waiting or get this one ??

i think i'll get both DEQ and DCX


do you think that i can input SPIDF in the DEQ, than output AEBU from DEQ to DCX
and then use the DAC from out the DCX!

do i need to upgrade the DAC on the DCX or not ?
is there a low cost possible upgrade that will actually give something ?

and i'd also like a quick link to a simple way to upgrade the PS from the DCX ...

lots of things to think about now..uprading computer this month !!!
and i am torn between cards right now !!
if i am using only digital out
in fact i wouldn't need any card at all ...
but i am not decided on what to do!
i only have a stereo setup
and i don't quite plan a surround setup
so i guess that i don't quite need super card if i use digital out!
problem is EAX ..some games don't even start if ur card don't support this! 🙁

My guess is that Behringer won't announce a replacement model until NAMM in January '06, if there is an upgrade.

Yes, you can input SPDIF into the DEQ, and use AES/EBU to connect DEQ to the DCX.

[/B]

No need to upgrade the DAC's in the DCX, they are very good quality in stock form. The analogue output section could use some simplifying/upgrading if you're into that. I haven't been dissapointed in my stock unit though.

and i'd also like a quick link to a simple way to upgrade the PS from the DCX ...
[/B]

No quick upgrade. It's a switch mode supply, supposedly quite good as is. You could change it to an analogue supply if you want. Don't know if it would be worth it.

My suggestion to you would be to get the unit and use it first, before thinking of upgrading. You might be happy with it in stock form. There are other issues to deal with when using this unit, such as input and output levels and a method of controlling the volume of 6 channels of audio (preferably after the DCX and before the amplifiers).
 
suggestion taken ...

i'll start my loudspeaker project first, get a new amplifier
( i need a good priced bryston 4B NRB or newer in good overall condition for the subs )
then i'll buy those units , if behringer hasn't present a better product than what is ...

i don't even think that i'll need to upgrade it for now
so !!!


advices taken! thanks all 🙂
 
Just thought about something!!!!!!!!!!!

The DCX doesn't seem to have any DIGITAL output ?
am i correct on this ?

I can't see any from the specs sheet at behringer.com

Cause that is too bad ..

i thought about something a bit ...
( well it wasn't real hard to think of neway..noob stuff)

If it would have a digital output !
it would be a nice upgrade, after some time
to just use external DACs of higher quality than the one onboards , before the analogue outputs!

So i would've used the DCX as is, as a crossover/dac unit
and later only use it as crossover and upgrade to external better quality dacs!

if it is not possible, as any of you worked on getting digital signal out of this unit before the dacs ?
completly bypassing them would be same i guess

thanks all, sorry if this is repetitive, i don't feel like going trhough the 50 pages of this thread...again ! 😛
 
JinMTVT, the DCX does not have digital output. Someone on the net posted how to modify the unit to do so though.

Why do you insist on upgrading the DACs when you haven't even used the unit yet? (unless you've got one recently and tried it, in which case I retract my statement). The DACs in the DCX are very good quality as is, adding external DACs will just add more jitter from the S/PDIF output and complicate your system (which will already be complicated enough by using a digital crossover).

Just try it, you might like it 😉
 
you are right transducer..i never used the dcx yet

but as a diy addict, i tend to like more projects and ideas than actual listening 😛
(as crazy as it might sound, but most of you here probably are in the same state as i am )
the setup and planning is often more fun to me than the actual use of the project 😛

so i was only planning my route as i go ..
 
i cna't say how old you are, but i amonly 26
and i think that this wisdom will come with age
( enjoying it correclty..not the projects )

But i still rather have tons of projects and no time, than listening to something that i don't understand! 😛
 
When I save a preset from the PC software to DCX everythings okay,but when I close the software and start it again,the presets is not in the list anymore.I can still switch DCX 2496 off and on again ,and it starts with my preset,why can´t I see it in the list from my PC?It´s not there
