It's going into protect. Unhook ALL the speakers and see if it still shuts itself off. If so, then it will have to be taken in for service.

It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.
When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.
If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.
If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.
On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".
If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.
I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.
If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.
If I can be of any further help, let me know.

The fans are a poor design the cool the amps inside. I could cook tacos on top of mine. Years ago I developed an external fan the velcros on the rear of the unit. Just find a silencer pc fan from pc power and cooling. Someone will be selling it online. If's a very low noise fan and will not disrupt hi fi output. Attach a plug in transformer to the power wirers on the fan. Make sure it is the correct mV, and amp rating for the fan, and just plug in to the 3300's switching ac outlet on the rear of the Denon. The fan will stick on the denon's outer case on the rear of the unit where there are a few vent holes with velcro. I did that so no warantees were broken by opening up the unit or drilling into the case. I have in instructions if you would them in a document. Just email me at firstname.lastname@example.org and put Denon Fan Instructions in the subject line. Enjoy, BWA

Disconnect all speaker wires on back and then turn on. If it happens again, it's most likely a power supply problem. If it doesn't happen again, it was probably crossed speaker wires.
