Behringer DEQ or DCX Noise

[bgavin]

These are digital EQ and digital crossover boxes. Both have a very frequent noise problem described as "frying eggs". There is a vigorous and active after-market that replaces the clock modules and almost the entire output path in these boxes. It seems kinda silly to invest $1400 into a $300 box.

Q: has anybody serviced one of these for the above symptom?

They have a lot of electrolytic craps on the various boards, and are reputed to have ribbon cable problems. I'm curious if a quality recap will directly affect "frying eggs" or if replacing the multitude of 25-cent opamps is actually beneficial.

Thoughts?

sounds like a job for a scope.

Evidently the "frying eggs" problem was corrected some time ago by Behringer. They are now installing an insulation pad between the metal chassis panel and the affected board.

I've seen a few photos of the DCX-2496 guts, and it looks like a candidate for a quality recap job.

Very surprising though, the DCX uses high quality ADC, DAC, DSP, same as found in the better DBX boxes. I'm not a component tech, but it appears even the opamps are of good quality.

Considerin the next step up is a Sabine or Xilica (sabine oem) at 4x the price, perhaps the DCX is worth the gamble.

a bit off topic, but the behringer mixers i've seen so far (the DX-1000 seems to be a pretty common one) had Jamicon. EVERYWHERE.

edit: and not just a couple ones here and there.. hundreds of those little b*stards..

Re: Behringer DEQ or DCX Noise

I have a new DCX2496 on order. The price is about a quarter of what I would pay for a Sabine or Xilica equivalent. When the warranty runs out, I 'll recap it.

Evidently they decided to use mainstream quality ADC, DAC, DSP and opamps. Same stuff as found in the DBX boxes at a much higher price.

The factory 'cured' the frying bacon sound some time ago. They installed an insulation pad between the chassis panel and the board to eliminate any contact.
