No, this isn't common at all.

The first thing is to rule out everything external to the amp, including any pedals. That's the most common thing l see. Next is intermittent knock-off SpeakOn cables.

Yes I eliminated all .direct into amp still no output to cab .did same for 2 different cabs both 4ohms.no protect light on and is getting signal.turned amp off waited 5 sec . works again .hosa edge speakon cable neutrik connectors.

I just experienced something similar on a gig. FOH was getting signal from the WD800's DI, but nothing was getting sent to the cab. No protect light, everything appears normal. Cycled on/off and then it worked. Seemed to have nothing to do with the speaker cable because I tried different cables.

Be sure that you are aware that the amp will not produce sound if the amp is turned on, then off then on again within a 20 second period. There is a short cycle lockout protection (covered in the manual).

If the problem persists, contact our customer service guys and they will help you get this resolved. I have no idea what the problem might be, we rarely see issues with these.

If the short cycle lockout protection is activated, does it still send signal from the DI out?

I don't think so but it's been years since I ran those tests.

Try the other jack on the speaker and/or the amp, every once in a while I see a damaged jack (usually due to a knock-off plug coming apart inside the jack and bending the fingers)

I tried both jacks on the amp as well as on the cab. Signal was passing through the circuit as far as the DI since it was gettin to FOH, but it wasn't making it to either of the output jacks.

I really have no idea what the problem might be. If it's under warranty, give customer service a call and see about it coming back to the factory for service. It it's out of warranty, I can take care of it at my R&D lab. Message me and I will get you the info.

Thanks, I'd like to do some more trouble shooting to make sure it's not something external. Poor connection at the speaker cable seems like the most likely explanation.

Do you get a signal at the effects send? Also, if you were to plug into the effects return does it pass a signal to the speakers?

Yes, signal was passing through the effects send, but not to the speaker.

Try cycling a plug into the effects return jack a couple of times and see it the problem goes away.

There's a Nickelback joke here somewhere

Circling back and offering a humble mea culpa -- It was indeed just a cable issue. My unit is fine. Apologies for muddying the waters on this thread!

Thank you for the update *and* for the honesty. This site would be a better place if everyone followed your lead.
