Why Does My Denon Receiver Sound Cut Out?

Denon Receiver Sound Cuts Out

Here we are going to address the problems that lead to sound-cutting out of a receiver. Your Denon receiver would cut out audio randomly or there might be a scratching sound every minute.

Plus, you wouldn’t be able to select among different audio surround options. Instead, you will get the stereo option only. Or the front face of your receiver might display only H/P Input On continuously.

Let’s learn the reasons before we move to the solutions:

Firstly, loose connections! You wouldn’t believe but the majority of the receiver problems take place due to the loose wire connections. When the connections are loose and unstable, things start getting wrong no matter what. So before you jump into lengthy and deeper solutions, check whether all the connections are snug and secure.

Secondly, Denon receivers tend to blow out more often. Doesn’t sound pleasing but sometimes the wires blow out even while you play the receiver. This prevents the sound from transmitting to the speakers and producing the desired sound. That means, the whole process gets interrupted.

Thirdly, dirt and debris! These dust particles get inside your receiver, particularly covering the internal sensitive parts of the system including the speaker holes, the switch buttons, and so on. It develops a layer and eventually, things get out of your control. 

An Easy Fix That Will Work Instantly

This is a quick technique that works initially. So if you are in rush or can’t wait any longer, try this simple hack:

  • Once you discover the sound cutting problem, turn your receiver OFF.
  • Disconnect the power cord from the outlet.
  • Wait for a couple of minutes.
  • Connect the power cord and turn the receiver back ON.
  • Play something and check whether the problem disappeared or not.

6 Ways To Fix Receiver Sound Cutting Out Problem

Now let’s move on to the troubleshooting solutions to get rid of this problem. The solutions are easy and trouble-free so you can try them at home!

1. Open Up Your Denon Receiver

Now, this part could be critical if you are not used to wiring and assembling. But if you are someone willing to inspect and work with the wires, consider opening up the receiver. Use a screwdriver and gently unscrew the receiver.

Check if there are any dust or dirt particles, especially inside the front face of the receiver.

Also check the wires inside, if they are damaged or not. Don’t forget to check the headphone port as well.

2. Remove Any Nearby Electronic Device

Electronic devices such as microwaves, usually hamper the signal and frequency of the receiver. Therefore, it hinders the proper transmission of sound. As a result of which, you get to experience the sound cutting problem again and again.

In that case, you need to inspect whether there is an electronic device around the receiver and remove it asap. If you are using a HEOS System, make sure:

  • The HEOS system is away from any nearby electronic device.
  • Make sure it is within the optimum range of the wireless network.

3. Get Rid Of Any Loose Connections

As I said, the majority of these problems start with loose connections. So, carefully inspect all the connections.

Starting from the wires, check whether all the connections are secure. If there are any loose wires, disconnect and reconnect them tightly. 

Look for any damaged or frayed wires. Use some wire stripper to get rid of those. Replace them with the wires that fit the terminal connections.

Otherwise, you will have a chance of blowing out the device very soon. The same applies to the speaker wires as well.

After securing all the connections and replacing the faulty wires, drive a test initially to check whether the sound cutting problem repeats or not.

4. Avoid Overpowering Your Receiver

We have this misconception of overpowering the receiver. This actually brings no good. Rather due to overpowering, the receiver tends to blow out entirely.

This makes the wires damaged, particularly the wires that transmit sound. As a result of which, there arises the sound cutting problem.

Moreover, due to overpowering, the speakers might also get in trouble. If the device itself gets blown out, the sound will not be produced in the speakers.

There is a sheer chance of the speakers getting blown out as well. And if that happens, there is no repairing.

You gotta replace the speaker with a new one. For replacement purposes, consult a technician to help you choose the right pair of speakers 

Similarly, underpowering the receiver also might get you in trouble. The receiver will shut down frequently.

On the whole, make sure that your receiver receives the required amount of power to function smoothly. I would recommend avoiding overpowering as well as underpowering the receiver.

5. Ensure well-ventilation

This is important because if the receiver lacks proper ventilation, it will start overheating and bring you more trouble. And this is something we really keep forgetting. Modern Denon receivers get hot quite often!

Placing your receiver in a congested place with no ventilation facility will start malfunctioning. It will eventually start overheating which takes things to another dangerous level. The wires might burst due to overheating and so there will be no room for the sound to transmit.

Take my suggestion: You gotta take this seriously and maintain your receiver every now and then. Clean it and make sure that it is in a spacious well-ventilated area.

This will not just keep your receiver good but will also improve its longevity and efficiency level.

6. Unstable Internet Connection

Have you experienced this sound-cutting problem while using a Wi-Fi connection? If so, then the problem could lie in your Internet connection.

An unstable internet connection could lead to such problems. As a result, the sound fails to transmit to the speakers and so so. 

In that case, all you need to do is check whether your Internet or local Wi-Fi connection is secure and stable.

However, when the connection is shared with a large number of computers or mobile phones, it turns slow or becomes unstable. In some cases, reconnecting the connection helps so you can try doing that.
