Right channel distorted denon UDRA M7

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.

You just need to replace your volume knob for a better one , a couple of bucks 10 dollar

I have a different model, but sometimes suffer this when power outages or other strange things happen. Its usually the microprocessor getting confused and not doing its job properly, once none of the speakers came on at atll!
In the handbook, it will tell you how to do a factory reset - that always sorts mine (Same brand, Denon). Just a pain setting it all up again.
You should be able to find a PDF version of the handbook online if your's is misplaced in the house move.

Sounds like a possible amp problem. Probably needs to go in for repairs.

If you have checked the speakers and wiring, the right channel has a audio driver or output problem, which explains the low volume, static, and distortion. A service technician will be required to fix the receiver so it will balance the left side.

Problems of this nature are often caused by electrolytic coupling capacitors. If you have access to an audio signal generator. Inject signal at volume control and compare left and right output levels. This will isolate fault to pre amp stage or power output stage. freezer can be very usefull in isolating this type of fault.

Crackling is usually a dirty control. Try using an electronics cleaner (with lubricant) and spray out all of the controls and switches. With the unit off, work the controls and switches back and forth to "spread" the lubricant. I would spray, work and spray again.

Update this with the results and also see if the crackling is related to the overall volume level. If tied to the volume level, there could be a transistor inside that is breaking down and causing distortion.

You may have two possibilities depending on the configuration of the turntable.
Your Denon should have inputs marked for 'Aux,' 'Line' and possibly, if it is built with the expectation of use with a turntable, 'Mag' or 'Magnetic.'
Your turntable may have a 'Line' output or only a shielded cable carrying a very small voltage from the magnetic head. I assume the pickup is magnetic and not crystal which has a much higher output level but also a higher impedance that requires a matching input.
You should have any of the above outputs in pairs and if the color coding conforms to current standards, there should be in- and outputs marked with red (right channel) and white (left channel).
I would first try connecting the turntable's leads to the 'Line' input since most later turntables have a small amplifier circuit built in that will take the signal from the pickup, amplify it, and match it to the levels and impedance of the line input on the Denon.
There isn't any danger of making a fatal mistake and you should hear right away if there is excessive distortion or a loudness even when the level is set to a low setting; this implies that the output from the turntable is higher than that input wants to see.

Audio output electrlytic capacitors have dried out, locate & replace them if you want your sound back, it's cheap but not easy.
