Behringer DCX2496 digital X-over

That is the signal from the DAC? what if you feed that into a active filter , which looks like a passive filter at frequencies high enough that the OP starts to ge tbandwidth limited? ie a proper post dac filter topology (not sallen-key)

and further removed by post filtering at 100kHz or more?

I mean, if my cell phone does not disturb the audio equipment ?

Can someone kindly pm me the the link or relevant thread regarding the analog input and output line matching trans mod for the dcx2496? I have bought the Edcor trans for more than a year but yet to start it yet. So now I would like to get detail instructions to start it. Thank you in advance.

DCX2496 Noise Problem:

I've had my DCX for 1.5 years now and have been having flakiness problems with the unit.

First one: power the unit on and the display goes blank with a BLIP like noise with a cycle of 3 per seconds. I litterally have to smack the unit hard to make that go away and start up properly. What the hell is that?!?

Second: I also get this random wind blowing mixed with scratching like noise in at least one of the output channels, sometimes two. It starts low then rises until it "pops" then the noise starts low again till it goes loud and pops and cycle continues. It is loud enough that I can't hear the good sound it's supposed to play. If I power down the unit for about 10 mins then it's ok again ...for about 3 mins then the noise comes back.

Anyone with same problem? Any solutions??

Does anyone have any feedback/comments about the Bunker BPD-1 Loudspeaker Management System? Is it better than the DCX2496??

Reseat all the wire connectors inside. Other than that it maybe PS problums.

Hi Andy, do you mean reseating the connectors onto the chassis?

[zigzagflux]

Your first problem was identical to mine. I identified the mating between power plug and board was the culprit; finally ended up removing the receiver on the board and directly soldering the wires to the board. It's really not that difficult of a job.

Flawless performance ever since.

[4pyros]

The connectors going to the boards. Disconnect and reconnect them all.

HI,
I removed the power supply connector and soldered the PS wires directly to the board,While you have the main board out visually check the solder connections on the big plug ,I have a few pins I didn't like and resoldered them ,clicks and pops are gone now!!!

To reset the DCX:

Switch the power on while holding pressed BOTH "page" buttons.

It's always interesting to see other products. This one has nice features, as the 4 ways, an integrated RTA for the mobile PA guys, then some discutable options as rather limited delays (12 ms !!!), or privilegiating a global graphic EQ rather than a multi band parametric by way.

But for me the non go warning comes from NO digital input and NO PC software control. A word of difference.
