Subwoofer hum with no input


It is not a bearable experience that the stereo process has a vivid or humming sound for the subwoofer.  Actually, a ground loop subwoofer hum causes voltage potential varieties into different units of the process.  Nobody would like to hear the subwoofer’s annoying sound, right? We hope you will not have to face it anymore. But how?  Now, we have tried to cover you with an easy reference to help you to understand why the subwoofer hums with no input and the ways to solve it. 

Causes of a subwoofer hums with no input

Some common reasons are there being subwoofer hum with no input . If you have the fate, then it might be for only a buzz loop. If the hum is for ground loops or any other causes, it’s a normal fact and you can solve it quickly.  Also from that, there are three main causes for subwoofer hums with no input. And, it depends on the type of sound that is coming out. We have mentioned the three types of causes below. 

  • The humming is tolerably low and it is also not increasing if you turn the volume up. 

So if this occurs, the cause of this problem should be from your subwoofer itself. Even, you may hear the power supply as it is not working as it should be. 

  • The sound is loud, it also depends on your volume up or down state. 

So, this is probably for a distemper from the main cable itself or the incondite subwoofer wire. Explaining to you in a better way, this type of buzzing comes due to electromagnetic obstacles hints. The electromagnetic obstacles hints impact your subwoofer to generate annoying noise in a higher or lower way depending on the volume of the subwoofer. 

  • The humming is clearly audible where it is not subjected on the volume of the subwoofer. 

This is the reason for the buzzing loop of the subwoofer. It is for the defender from the subwoofer power supply to the source unit to the sub. And lastly, it makes a very annoying sound. 

What procedure do we need? 

First of all, if there is any technical problem then you are required to follow some steps which we have noted. If the disorder is the reason for the cable or power supply, then you can try to plug the subwoofer in another power socket. If this method works, then plug the subwoofer back to the preceding plug socket, still this time replace each and every device from the socket. At times particular devices or charging devices might occur buzzing for the subwoofer. If the disorder insists then must contact any technician, it could be a reason with the power supply of the house.  It could be that the buzzing is occurring from the loudspeakers. This can be the reason when the cables are inexpensive or not taken care of properly. Still this is often the problem. To test it, rearrange the cables or use small and shorter cables. You could try a variable wireless subwoofer which even can be a great way to entire a subwoofer in your house. 

How do you know what’s the reason for humming?

We have already discussed the three hums above.  To know what’s actually creating the hum, you have to do some tests.  The first problem of loud sound may need a substituent of your subwoofer.  When changing your subwoofer, you will require a new one. Please check on online websites to get a new subwoofer. Whereas, replace the sound volume and try to find out the next reason. When you recognize that the sub has stopped buzzing after doing it, then the humming loop is the cause. 

How do you get a cure for Subwoofer Hum with no input? 

To get a great stereo system, you should ignore the noise of the subwoofer hum with no input. Though we have discussed the ways that will favor you to correct the subwoofer hums with no input.  Please go through these points thoroughly for better understanding. You can also try out these steps if the previous ones haven’t worked. 

Alter the opposite of your sub’s connection

Probably, replacing the opponent of your subwoofer’s connection is the simplest way to analyse the problem. After doing that, you will invert the subwoofer power plug’s way.  Here and there, the prongs constrict the opposite way. In that fact, take an AC ground adapter to invert the opposite. 

Invert other plugs

If the interior units have a similar power supply source, then the disorder would be anywhere more than in the subwoofer. Look out for the two-prong AC plug. Then, invert the way of direction of the other plugs.

Keep the cables detached 

Mostly we find the power or sound cables are combined in piles. Then divide the cables at a certain distance.

Switch vents

As said previously, the subwoofer sounds may create a ground loop. It happens if the subwoofer is battling another part of materials in conjunction with the ground. For this reason, take your subwoofer to the other AC circuit. You may even need an extension cord to join the sub with a separate wall power vent. 

Get an audio separation transformer

If the grounding process of the last solution did not work out, then you just have to get an audio separation transformer. It definitely works to solve the ground loops.

Final Thoughts

The case is that the preserving can be caused by the subwoofer hum with no input, either you connect an input device or not. You can also disconnect all the inputs, replace the speaker cables, AC plug powering the unit, and loudspeakers though listening to the 60-hertz hum. Most of the cases, only plugging the unit into the AC wall vent can be the direct output of this lower audible sound. Therefore, your subwoofer hum with no input has been disordered by electrical defects, involving annoying sound, ground loop loud noise, or upstream problem, you can use this easy assist to understand the actual reason for the subwoofer hum with no input. Discover your problems to help you fix the hum, reminding you about the problem that can happen from different types of problems not only from a single cause.
