Behringer DCX2496 digital X-over

[WiredforSound]

Try a Dolby Lake or BSS filter...

I know its quadripple price over the DX2496 - however so is the sound quality...
Once u have heard a quality filter u won't settle for less

Xilica

Been using dbx driverack pa for years and not so happy with the sound quality. Xilica seems to be almost as good as XTA but for much less (from what I heard from a sound company, AIS Audio).

Any audiophiles using Xilica processors?

Minidsp input board can it be used?

I am looking for a simple Spdif / optical imput on my dcx.

Minidsp has a new product and I am wondering if it does the trick.

It is called Digi-fp

Please advise

Thank you Peter

I believe Pano and others have had success just pumping the SPDIF straight into the existing digital input. Gotta' be worth a try.

I do the same. Works perfectly.

Toslink to spdif ordered

Thank you all for the help!!

I will be using this

TOSLINK Optical Input Module

Toslink to spdif adapter

 

[Pano]

That module look like it will do the trick.
If you have the DEQ in front of the DCX, you can come optical into the DEQ, then out AES/EBU into the DCX. That works very well, too.

...or even a SRC2496 will do the trick.

 

[Pano]

Ah yes, good thinking!!

I have a problem with mine, it loosing the sound while switch on and of other equipment in my apartment. For example; Turning of the roof lights and the unit mutes for 2 sec.

I have replaced the 110 ohm r with a 83 Ohm while doing a direct spdif mod. But this would in my apinion only do good?

Any solutions?

 

[Pano]

I used to have that problem with a long SPDIF cable (about 8 meters). It turned out to be a grounding problem. Ceiling lights and sometime even the air conditioner at the other end of the house would cause the problem when turned on or off. Once I had installed a better ground in the listening room, the problem went away.

You may want to look at grounding problems in your house electrical system.

flat-cable pin out spreadsheet

FYI

I made a spreadsheet containing the information on the flat-cable pin out based on the Behringer schematics. Only did the in and output cables!

For me it is useful, hope it is for others too.

May contain errors!! So please check for yourself.

Good info

Peter,
Good info, thank you.

Pano,
I had a grounding issue (hum, rather than dropouts) with long SPDIF/AES cable from SRC2496 to DCX.

Solved with tiny pulse transformer pulled from an old network card.

It even fits in the XLR plug

Hope this is useful to someone,
AP

Auto,
please explain with a schematic.
What is a pulse transformer?
Where else might one find them?
How does one recognise them?
What type of problems are they capable of solving/attenuating?
etc?

 

[SY]

Andrew, these are the ones I use:
http://www.murata-ps.com/data/magnetics/kmp_da100.pdf

As with any other sort of input or output transformer, they provide galvanic isolation and bandwidth limiting, as well as being able to interface single ended and balanced circuits. Other types are useful for impedance and level transformation (e.g., AES/EBU to spdif).

Twisted Pear Toslink input installed

The twisted pear solutions works very well and is easy to build / instal.

Stole the +5V / GND directly from the output pins of the power supply.

I have not changed the resistor value at the input transformer. What advantage would this bring?

 

[AndrewT]

The Murata and maybe the cs2501 appear to be 6pin devices.

Are the middle pins for a centre tap?

Do all pulse transformers come in 6pin format?

Hi Andrew,

Sy's link shows 4/6 pin, but not CT.

IIRC I never found a cs2501 datasheet, only for similar parts (some CT).

It seemed logical that NICs would use them (imagine office building ground loopiness otherwise); and if OK for 10mb/s ethernet, SPDIF should be a cinch. So I went rummaging, and found something that measured equal R from centre to side pins, open circuit from one edge to the other, and looked rather like the 4-pin one in my tube Dac ("pulse transformer" on Sheldon Stokes' BOM).

In it went. I was delighted when it worked!

Best,
AP

PS, My first and only use of 'looks like' for component selection, honest

 

[SY]

Not much use for a CT in this application.

 

[Pano]

Cool! I also used a pulse transformer and it worked well (IIRC) until I tripped over the cable and pulled the poor transformer apart!

Sending the SPDIF signal over a balanced line is a good idea, if much distance in involved.
