Any noise that results from that cable is usually to do with grounding.Ī power cord typically has two kinds of plugs on either side - that is, if one of them isn’t attached to the speaker. ![]() Aside from the audio cables we’ve discussed, there’s also the power supply line that leads from the speaker to the nearest power outlet. There are two kinds of cables that are connected to your speakers. Still, we’ll discuss a solution to this problem later on. You see, any device with a magnetic field can cause interference - your phone, your mouse, even some lighting devices. Even though they’re susceptible to picking up noise due to outside interference, those cables work perfectly well in quiet environments.īut if interference is the problem, couldn’t you take it out of the equation? Well, depending on your computer or studio setup, that may not be as easy as it sounds. Most commercial speakers, whether they come with built-in or separate cables, have unbalanced wires. Of course, that’s not to say that these kinds of cables don’t have their uses. That makes them vulnerable against outside interference, which often results in a low buzzing noise around 60 Hz. It simply means that there are two wires instead of three inside the cable. Both RCA cords (the kind with red and white plugs) and sturdier instrument cables can be unbalanced. The underlying problem here is that the cords you’re using are unbalanced. What’s more, the buzzing will get worse as other electrical devices come near the speakers. If they’re causing the distorted noise, it will persist even without audio output. The cables that connect your speaker to the audio source are the first thing you’ll need to check. With that in mind, let’s try to figure out exactly why each of these scenarios could lead your speakers to start buzzing. ![]() For example, if the audio drivers on your computers are out of date, you might hear strange sounds coming from your speakers. One of them is structural - a blown speaker could sometimes produce a buzzing kind of noise. On the other hand, two other things could cause humming sounds. Try to eliminate the noise by replacing the cords connecting the noisy speaker to an electrical outlet or a sound source. That assumption may even be correct and there’s a simple way to prove it. If you’re hearing a persistent buzzing sound coming from your speakers, you may assume that the issue is electrical. ![]() Should You Remove the Ground Pin From the Power Plug?.Get a Hum Eliminator or an Isolation Transformer.Plug the Speakers Into Different Outlets.
