Denon AVR-2803 : No sound from Zone 2 Speakers

After working great for 3 years when I tried to turn on Zone 2 (lately) the whole AVR unit shut off. I reinitialized the microprocessor (per the manual) and now I can select Zone 2 with the unit remaining on. However, I still can't get any sound from any of my Zone 2 speakers (Zone 2 volume is up enough) from any source. Thanks.

    Are you running the system in 5.1 surround or 7.1 surround? If you are running it in 7.1 surround, the unit will allocate the power for the second zone to the 2 extra speakers for 7.1. You man need to change the settings in the menu to allow this.

Could be bad connection. Try to tight connection cables on receiver and TV.

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.

You have to switch your remote into Zone 2 Mode. It will be an option on your remote. Once you put it in that mode, you can change the source just as you would Zone one.

One or the output channels is probably bad you can check for a short on the output transistors using an ohm meter. Make sure that the receiver is un-pluged. The ouput transistors will be on a large heat sink.

Check your speaker wires on zone 2 and look inthe manual for speaker configurations with zone 2. you may have a speaker conflict. If you still have an issue, post a comment with your speaker setup and I'll help some more. Hope this helps

SOURCE: Denon receiver AVR-3300: Unstable source selection

Very important you have run system set up menu it configures your receiver with inputs analog or digital,speaker size,input,room correction etc Different input modes can be selected for the different input sources.
The selected input modes for the separate input sources are stored in
the memory.
q AUTO (auto mode)
In this mode, the types of signals being input to the digital and
analog input jacks for the selected input source are detected and
the program in the AVR-3300’s surround decoder is selected
automatically upon playback. This mode can be selected for all
input sources other than PHONO, MD/TAPE and TUNER.
The presence or absence of digital signals is detected, the signals
input to the digital input jacks are identified and decoding and
playback are performed automatically in DTS, Dolby Digital or PCM
(2 channel stereo) format. If no digital signal is being input, the
analog input jacks are selected.
w PCM (exclusive PCM signal playback mode)
Decoding and playback are only performed when PCM signals are
being input.
e DTS (exclusive DTS signal playback mode)
Decoding and playback are only performed when DTS signals are
being input.
r ANALOG (exclusive analog audio signal playback mode)
The signals input to the analog input jacks are decoded and played.
t EXT. IN (external decoder input jack selection mode)
The signals being input to the external decoder input jacks are
played without passing through the surround circuitry Your remote is searching for inputs because you did not properly run system set up!!! Here is a link to your manual [PDF] AVR-3300/1 3.3E*

Extended power loss might lose memorized settings. Pretend the unit is brand new and verify all of them. No video from CD??? Really? Good luck with that.

Denon AVR 1609 volume Zone 2


Logitech recommends that zone 2 is controlled using device mode on your Harmony remote. Controlling zone 1 and zone 2 simultaneously within activities may lead to the AV Receiver turning on and off unexpectedly as you switch between activities. For example, if you try to turn on zone 2 within an activity, it may turn on or off zone 1 and vice versa. Controlling zone 2 in device mode will prevent this from happening.

Denon AVR 886 only shows analog input


Are your speakers able to handle the 886's power. I have the same reciever and changed by speakers as the Denon would turn off instead of frying the speakers.

As for the digital, have you used the option to change your audio feed and video feed. (for example - I'll show photos through the front input but use the CD -digital for music. Maybe the audio feed is locked onto an analog input. Just a suggestion.

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 1609 Receiver Zone 2 has no sound


you have to change the power amp assignment to zone 2, you must also have Analog audio connections to the Denon from your devices.
Try this put your remote in the zone 2 mode, select tuner in zone 2 and turn zone 2 volume up to -10

Audio Problems with AVR-2803


Hmmmmm Sounds like one of 2 things....

1 Your DSP board is toast. ( not much hope, it must be sent to Denon as they do not have anymore entire circuit boards for swap-out replacement.

2. Heres the hope part......Inside your denon is like a computer.....there is a main board, separated by the big silver heatsink, and then there another main board. On the main board closest to the volume control, the DSP boards and Video boards plug into the main board . The DSP and video boards are up and down ( when the receiver is laying flat, like normally ), and they plug into the main board from the top.

Denon is NOTORIOUS for bad solder joints and the little white connectors that connect the "motherboard" to the DSP and Video boards are of suspect quality ( the rest of the unit is great )....So it COULD be that you have a bad solder joint on one of the connectors or the connector itself. There is also another set of connectors that joins the front panel display to this "motherboard".....these colder connections are also suspect.

I would have a denon repair shop look at it as I GUARANTEE they have seen this before.......best of luck...Rob
