Reasons why Denon receiver sound cuts out

There are several reasons why Denon receiver sound cuts out. First, cables loosen while playing music. Loosened wires cut off the connection to the receiver resulting in sound cutting out. Secondly, wires can blow out while using your Denon receiver. Once the wires have been blown out, they cannot allow the sound transmission to the speaker, interfering with sound being produced.

Ensure you regularly check your device wires to ensure they are in good condition. Dust accumulating on interior parts of your system, especially the speaker holes, form a thin layer that insulates your device preventing sound production. Lastly, Denon recovers blowout while still in use immediately cuts out the sound. 

Steps on how to troubleshoot Denon receiver sound cuts out

The following steps will help you troubleshoot the sound cuts out the problem.

1. Turn off your Denon receiver

Once your Denon receiver stops producing sound, turn off the system immediately and disconnect it from the power source.

2. Open the Denon receiver

Locate the position of the receiver cover and unscrew it gently using a screwdriver to remove the cover. Pull the cover and inspect your Denon receiver.

3. Switch off any electronic device nearby

Sometimes, electronic devices may interfere with the frequency with which sound is transmitted. Electronic interference can cut out sound productions after weakening the frequency of transmitting sound to the speaker. Therefore, switch off any electronic device and test your device to check if the sound is produced. If the issue is not solved, try another method.

4. Check device connections

Scrutinize your device. Check if the wires are loosely connected, or they are blown out. For loose wires, use a wire stripper and strip the loose wires. Connect them correctly and tightly to prevent them from becoming loose again. Ensure you match the terminals of the wires to avoid blowing out the whole device. 

If the wires are completely blown out, you need to replace them. Buy wires that suit your device and try connecting them carefully while following the manufacturer’s instructions. After replacing the wires, test your Denon receiver and see if the sound is produced effectively. However, if your device fails to produce sound, wires were just part of the problem.

5. Check the amount of current the device is using

Overpowering your receiver while using the system may blow out the fuse, wires transmitting sound or even the whole system. Once wires transmitting sound have been damaged, the sound is not transmitted to the speaker resulting in the speaker not producing any sound. The blown-out wires will require immediate replacement for the system to function again.

If the fuse is also blown out, power transmission to the system is interfered with hence shutting down the receiver. Once the receiver has been shut down, the sound being produced is also cut out. Therefore, immediate replacement of the fuse can make the device produce sound again.

Moreover, blowing out the whole device cuts sound production by the speaker. Replacing the device with a new one can enhance sound production. Finally, the low power supply automatically turns off the receiver. Once the receiver turns off, all receiver parts stop functioning, including the speaker. When using the receiver, ensure you use the required power amount to keep the system functioning. Avoid overpowering and underpowering your device.

6. Check the device for any dust

Dust blocks sound openings hence cutting sound being produced. Use a vacuum cleaner and blow out all dust leaving the sound holes unblocked. Also, you can use compressed air to get rid of all dust that insulates sound holes.

7. Check the speaker condition

At times, your speaker can blow out hence unable to produce sound. Blown out speaker is beyond repair and needs replacement. You can decide to replace the speaker or the whole system. If you are replacing the speaker, ensure you buy a speaker that fits your device type to avoid damaging the whole system. Consult an electrician before replacing the speaker to guide you on the best speaker model that suits your device.

Moreover, check the speaker wires and identify any problems. If the wires are loosely attached, try fixing them using a wire stripper firmly. But if they are completely damaged, install new wires and fix them correctly. Test the device speaker and check if it produces sound ideally without any challenge. Dispose of the damaged wires according to the manufacturer’s instructions.

8. Check your device if it is overheating

Overheating devices interferes with the sound being transmitted to the speaker hence cutting out a sound that is being produced. To fix the problem, make sure you install enough ventilation to get rid of excess heat. Also, turn off the device before the whole system is permanently damaged and try troubleshooting the problem.

Overheating can also cause sudden switching off of the receiver and therefore cutting off the sound being produced by the speaker.

9. Examine the whole receiver

When using your receiver, it may blow out hence shutting down all components. To troubleshoot the problem, visit a nearby local repair shop for a professional to fix the problem, but if your device is beyond repair, replace the receiver by buying it from a licensed seller.

Ensure you maintain your receiver often. For instance, avoid using the receiver in direct sunlight and frequently clean the device to prolong its lifespan and improve its efficiency. Finally, check your device regularly to identify any problems soon enough.


If you experience a problem with your receiver cutting sound, apply the above steps and troubleshoot the problem. If the problem persists, you can always contact a professional. The steps above are easy to apply.
