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

To add a 2-channel amplifier to your Denon AVR 2307ci receiver, you can follow these general steps:
1. Determine the amplifier connection type: Check the specifications of your 2-channel amplifier and identify the available input and output options. Common connection types include RCA (analog) and speaker wire (for binding posts or terminals).
2. Identify the pre-out connections on your Denon AVR: Locate the pre-out connections on the back of your Denon AVR 2307ci receiver. These are typically labeled as "Pre Out" or "Preamp Out" and may be color-coded. You will need to find the pre-out connections for the front left and right channels.
3. Connect the RCA cables: If your amplifier has RCA inputs, use RCA cables to connect the pre-out connections of the Denon AVR to the corresponding inputs on the amplifier. Connect the left channel pre-out on the Denon to the left channel input on the amplifier, and do the same for the right channel.
4. Connect the speaker wires: If your amplifier uses speaker wire connections, connect the front left and right speaker outputs of the Denon AVR to the corresponding inputs on the amplifier using speaker wire. Make sure to observe the proper polarity (positive and negative) when connecting the wires.
5. Configure the Denon AVR settings: Access the setup menu of the Denon AVR by using the remote control or the front panel display. Navigate to the audio settings or speaker configuration section. Look for an option to enable "Preamp Mode" or "Preamp Outputs." Enable this option to ensure that the front left and right channels are redirected to the pre-out connections.
6. Set the amplifier to the correct input: If your amplifier has multiple inputs, select the input that corresponds to the connection from the Denon AVR.
7. Adjust volume and settings: After completing the connections, you may need to adjust the volume levels on both the Denon AVR and the amplifier. Use the Denon AVR as the primary volume control and adjust the amplifier's volume accordingly.
It's important to consult the user manuals for both your Denon AVR 2307ci and the 2-channel amplifier to ensure proper setup and compatibility. If you're uncertain about any specific steps or settings, it's advisable to consult the manuals or reach out to Denon customer support for assistance.

Hi,
You can download the user manual from here:

Just scroll down and enetr the verification code. It should tell you how to achieve what you're looking for..

Hope that helps :)

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.

chek the sleep mode

Fined in owner's manual section about MULTI ZONE CONNECTION AND OPERATION. page 68. If you don't have a manual, download it from here : http://www.usa.denon.com/AVR-3808CI-OM-E_404A.pdf

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

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).

Drop the front panel of your receiver,there is ZONE 2 ON/OFF switch.
Good day!

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.
