Thanks. We also have Jan's comments. Maybe I can tune up my DXC so I only hate it. I have kept my paws out of it as I don't have a USB-microscope yet to deal with the SMD.
Behringer is building exactly what the price point says, but some of these flaws are inexcusable. The level of HUM would make the DCX un-usable for anything more than a garage band. It's turn on and turn off noise make it un-usable in a home. I tried to put just enough filters in it to deal with my sub, and it was out of memory. RS232 in today's world? Give me a freeking break.
They are cheap. Really cheap. Though the DBX analog crossover is not really any better than the Behringer. I would not worry about repair. They are at a throw away price point. Two way shipping, and just the overhead for repair makes most of their stuff BER. Their market is semi-pro and garage bands. You know, really poor people. I don't blame them for serving their market. I blame them for design as that is a low one time cost.
Either that or just e-bay the thing.
I haven't looked, but the DBX unit may have a better analog section than the Behringer. The time it took to mod the Behringer isn't worth it. Plus I had to be VERY delicate lifting the ADC and DAC, SMD pins off the circuit board so I could solder tiny wires to them, which then had to be physically buffered. Should have been a neuro surgeon, but noooooo, I had to go the electronic route... Anyway, not recommended. My I/O board was intermittent, so I was already faced with that. New I/O boards weren't available. So I fixed it best I could.
I don't know anything about what Behringer does in the digital domain, such as over sampling. I do know that most downstream amps cannot handle Rf or digital noise elegantly, so puting a passive Rf filter at the output of any DAC never hurts, in my opinion.

Jack likes to be paid for his labor, but not excessively. Just for his time and effort, and the raw materials that he puts into his stuff. He just does NOT SKIMP on quality materials or avoid exotic physical concepts. Speaking of that, I am sending that new version of electricity transmission to him. It isn't much different than what we have always known, but it is put in a more popular format.

Was listening to a several thousand $ full range augmented by woofers one brand system.The salesman, who refused to back off the volume, yelled that it was amazing how bright a system could be and still remain musical.
Fled the room followed by his laughter after I said I'd built and sold speakers to my friends while in high school and I could probably do better myself.
5 years and 39 pairs of mostly all different designs sold later , I'm still learning and having fun with it as a casual side job.
Salesman aside, I gotta agree with that great American who said "if you think you can, or if you think you can't - you're right".
That is not true marce, I have seen Jack's resistors and they do not come from Digikey or any other usual source.
Could be. This is a couple days of work, not much more. Most of the elements are pre-packaged, very little code writing to tie it together.
make my day where! 'Top Secret Supplies R Us' who deal with only ITAR registered companies and moonlighting Audio designers😀
of course the rest of the electronics world seems to do OK from the usual sources
Misconceptions described in a popular form are still misconceptions. Every few years someone 'rediscovers' that electromagnetic energy does not travel through the wires but through the space around/between them. This usually happens when they hear about the Poynting vector, but completely misunderstand it. Some EEs have even built a career on misunderstanding the Poynting vector!john curl said:
The Poynting vector does not tell you where the energy flows. The surface integral of the Poynting vector over a closed surface gives you the total energy flow through that surface; that is all that Mr. Poynting claimed in his conjecture. These two statements may seem equivalent, but they are not.
They seek him here, they seek him there, those audiophiles seek him everywhere.
Is he a Genius, or is he a Dick, that damned elusive Patrick.

If the source and load are low impedance, and the line is high, the system settling time will be far longer than one transit time. It can climb into the realm of audibility.
As has some physicists...
badaboom..😛
