It may be from the spdif mod? i doubt that behringer would have released dcx2496 if it was present? Just strange.

Can grounded pin prevent a swing in the phase? May it be the PSU that aging?

I use the behringer src -deq-dcx in that order,the deq and dcx are about 3metres from the src ,the src is with the cd and pre-amp in my listening position.
When the dull odd sound happens i just toggle between src and ad or change the conversion rate,this always sorts out the problem,have never had to power anything off.
I've tried sending 96 -88 -44 but they all have the same problem,never new which unit was causing the problem though.
I've used these units for many years now and often press the button just to make sure that everything is locked in.
Apart from this minor irritation i would not part with them ,if only there was a quick fix!!!

Default Stupid question

Background:
I have a modified DCX2496 running for a long time in my system. I have installed the Pilgham Audio analog and clock mods. I use it with SPDIF input only directly from a computer.
lately, it started giving me troubles. it started with digital hiccups and now it is completely mute.
Question:
until all this started, I had my unit on all of the time. in order to reset it I turned it off and on again. it doesn't turn on immediately but blinks its display and one column of leds on the input leds and output leds for some time before it steadies. is this normal or hints of a problem? I simply don't remember how it behaved when it was OK since I never turned it off...

Have you checked your power supply capacitors? I think they often go bad in these units - Behringer are known to use low quality electros at times.

Default capacitors

visually they look fine.
checking voltage with a Fluke on the connector to the DSP board also looks fine.
Should it blink or not?

Give me a minute or two and I'll fire mine up.

Get one of those cheap chinese ESR meters that can measure in-circuit. Truly invaluable tool - many electrolytics that look perfectly OK can still have dried out

can have bad diodes too, Behringer iNuke series International Rectifier sold them some iffy stuff. I used to trouble shoot for a living, we always O-scoped the DC rails on AC. Careful not to apply GND with a scope probe GND where it does not belong Better to float and guess
