DEQ2496 continual reboot(?) Help!

lcjohnson · 4th July 2007, 07:03 PM

I have a Behringer DEQ2496 that signal wise sits between an SRC2496 and a DCX2496. It has been used in a home stereo for about 2 years.

Starting about 6 months ago I got an intermittent signal cutout during the first 10 minutes of warmup of the DEQ2496.

Now when I turn it on, the front LEDs blink together every ~1/2 second. This is continuous, otherwise nothing else. Is this a cyclic reboot?

I took the cover off and poked around for shorts or burned components, exercised the connectors, etc., - to no effect.

Anybody out there had this problem? Any suggestions? Otherwise I'm looking at 300 clams for a new unit...

I had the same problem with mine when it arrived used via eBay. I removed the boards and put tape down on the bottom of the chassis and put everything back together. It was a stab in the dark, as this method of "repair" fixed a shorting issue I had with one of my DCX's a couple years ago.

So far so good, no rebooting since then. (knock on wood)

Good luck.

Same cyclic reboot here, click/clack from relays & display on/off in an infinite loop.
Stab in the dark n.2 for me: lid removed, exercised PSU connector and... it looks like to work right now without lid on.

Overheat? PSU cable connector?
Is PSU going to R.I.P.?

Hi, My DEQ2496 from eBay has started to do this too very intermittently. I saw an Amazon review where somebody put heatsinks on the Sharc DSP's to fix their issue. I plan on "all of the above": tape on the chassis, check the PS connector and put some old motherboard northbridge heatsinks on the DSP's. Another poster also mentioned that running the RTA for extended periods leads to issues, which points to a potential heat problems. If this doesn't work the next step would be PS cap and regulator replacement.

Also, anybody know where I can get Seoman's remote control software for this thing? The link is down.

You could try the linear PSU mod:
