Denon AVR-1804 6.1 Channels Audio Problem

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.

This video MIGHT help a little

Without knowing exactly what your problem is, perhaps you are not playing sound that was recorded in at least 5.1 format. A DVD or BluRay will indicate the format on the cover. The data is decoded and split into (for example) six discreet audio channels. Left front, Centre front, Right front, Surround Left, Surround Right and LFE (Low frequency effects) If you are playing a standard stereo audio disc, then the sound will only be heard from the front L&R speakers, which are expected to be full range speakers. You can, however choose an audio configuration that also provides a signal for the SUB (LFE) and even a pseudo surround. If you want more info I'm happy to help. Just tell me exactly what sound source you are playing and we can work it out.
Cheers for now, Don.

Mr Paul.. Thanks ur valuable information . I got a unit and it had one power transistor gone. even after replace not work but I follow ur instruction done. Appriciate.

Because in order to use a digital input, the unit would have to completely power on. Zone 2 is designed so that it can be used with the main power off.

You don't say how "TV audio" is entering the system.

My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.

I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.

If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.

You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.

Denon AVR 2500 Operating Instructions Manual

You need to get the manual and do some reading first. I couldn't find the AVR-1804 but the AVR-1803 is avaiable. It should be close enough to get you through connection and setup.

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.

Front panel button engaged for 5 or 7 channel operation? Also check front panel rear surround speakers button is engaged. Should get you back to 7.1 unless you have changed the rear surround speaker setup for a 2nd zone, also be sure you have a 7.1 DSP setting enabled.

Of your five plugs, a red and white next to each other will plug in to the audio in on your denon (Red is for Right) I would use something like the VCR-3 pair on the left side of the rear panel. The other three, Red Green and Blue are for Video Component In on the denon; Use either Video-1 or Video-2 in the component section on the right half of the rear panel.

At his point, it will be best to look at the manual, because you will have to pair the two items together in the menu system. It takes a little patience but isn't too hard.

Good luck.
