Question about Denon AVR-4802 Receiver

1 Answer

Denon AVR-4802R automatically shuts off in multi-zone mode

When operating in multi-zone mode (after amplifier was off for couple of hours), the amplifiers shuts off automatically. At this point only Standby light is blinking and the amplifier responds to only OFF command.

After turning it off, the main zone can be back alive and operates fine, but the moment multi-zone is turned off, the amplifier shuts off again with same symptoms.

After turning it off, if it the mult-zone is turned on instead of main zone, the amplifier shuts off instantaneously. So basically turning muli-zone turns off the amplifier.

Leaving the multi-zone off for some time with just main zone operating, turning multi-zone agains for a while and then the system shuts off again.

So it seems like the amplifier is heating up and decides to shut down. But touching the body of the amplifier, it does not seem to be very hot.

I had the volume of the multi-zone tuned too high and was attenuating it in an external control box. Once i took the multi-zone volume down to -25db, the problem went way. My main zone was operating around -35db so did not have the problem.

Denon instructions


I don't have this particular model but I have owned 2 Denon receivers and I suspect yours is similar. On my Denon there is a manual speaker set up with a test tone for each channel. This will allow you to boost or reduce the DB level of each speaker individually. I would do this while sitting where you do while watching TV. be sure:

1. The receiver is in surround sound mode to do this.
2. My receiver also came with a microphone that can be plugged into the receiver to allow automatic level set up through what Denon calls the "Audyssey" set up. The equalizer setting are also located in the "Audyssey" settings.


You might check your manual before you begin.

Denon AVR-4802 multi-zone problem.


I had the same questions and still can't believe there isn't more information on the topic. It's crazy how much marketing Denon devotes to their Multi-Zone features yet offers very little reference materials on the actual set up. I guess most customers don't use the fearture? Here you go:

-The Multi-Zone on the Denon 4802 is analog only. If you are running digital coax or fiber you will have to run a second line that's analog (eg RCA red/white) from the source to the Denon in order for the signal to to make it to the Zone 2 speakers (regardless if it's Pre-Amp out or direct connect to the Zone 2 speakers from the multi/SB speaker outs. Regarding the Harmony question, I had the same problem with my Harmony 880 and wasn't able to find an answer after multiple searches. Luckily I figured it out when I deleted the receiver from the Logitec device list and started over. Connect the remote to your computer, launch the Logitec Harmony Remote Software, click the Devices tab, hit the Add Device, pick the device type & manufacturer from the drop down list, enter "AVR-4802" under Model and finally hit the Next button in the lower right corner of the UI. The next page solves the Harmony Zone 2 control problem. You will see a message "To use your device in additional zones/rooms, click the checkbox...." Make sure Room 2 is checked (mine was not), update the remote and you're done. The Harmony Device menu you will now contain a second receiver icon called "receiver 2." Hit "device" on the Harmony, choose "receiver 2" and you will gain control over Zone 2 including volume.

Good luck!

Denon AVR-3805 zone 2 no longer working


time to reset the microprocessor. See page 87 in manual.
1) switch off the unit using the main unit's power operation (small power button)
2) hold the PURE DIRECT button and DIRECT button at same time and turn the main unit's power operation on.
3) wait for entire display to flash in 1 second intervals

now the speakers need to be set up again but zone 2 will be working. i suspect a power surge causes the microprocesser to be corrupted. i put a power surge protector and have not had problems (lately).

Denon AVR-1907 blinking red power button


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.
