You sit down to relax and listen but notice something is off. A conspicuous, persistent hum emanates from the subwoofer, and it shows no signs of going away. Check the surrounding structures to find the problems of your amplifier. You can demolish the humming sound by replacing the capacitors.
If your home theater subwoofer buzz, you should find the main cause of this issue. Resolve these issues as soon as you can and save the overall home theater system. The brand has poured its knowledge of acoustics and digital tech to produce an affordable powered subwoofer for small to medium-sized rooms. High-level inputs accept a full-range signal from the amplifier's stereo speaker outputs.
Subwoofer Hum
The addition of an audio transformer in the electric passage of the subwoofer is an excellent solution. It identifies the signals and then converts them to the required information. In the absence of these devices in the ground connection directly produces a buzzing sound. It is a repairable issue, and you can also consult with an expert person to discard the buzz.
The interference of signals occurs when you connect more than one external device to the receiver. It is a composite of electric connections and wires, and all of them work in coordination. The looping and humming of the sounds also occur due to insufficient signal transformation. Again, this is because digital and analog signals compete for the production of sound conditions. The issues travel from the grounding section to these tools.
Mixing of electric wires of home theater subwoofer
In case of any complicated challenge, it would be of help if you consult an expert to guide. After you have exhausted the option above and still the humming sound is there, then you need to replace your amplifier altogether. However, you can also check if the components share a common source.
To get rid of hum without having to throw out some of the desired audio at the same time, we need to start by understanding what the various possible causes are. When components share the same source, such as a power strip or surge protector, the culprit may not be the subwoofer. One by one, reverse the orientation of the other plugs to see if it makes a difference. Enjoy the high sound quality with these small fixing techniques. There is no need to change the wiring and other surrounding equipment. Detachment of multiple devices also provides one identifiable part for the sound tools.
How to Fix Subwoofer Hum
It may be necessary to use an extension cord to reach a wall outlet that is separate from the rest of the stereo system. You can use an isolation transformer, similar to the type used for cable TV ground problems, to eliminate the electrical connection from one component to the other. These transformers are inserted in line with the audio signal connection between the two components. If there is no audio connection between the components, the problem may be current flowing through the video portion. In this case, a video isolation transformer should be used to eliminate the ground loop.
If you find out it is the case, then the AC plug could cause sound and not your subwoofer. Well, yes, how do you fix the subwoofer after you find that there is a hum even after you remove the input? Observe the problem of signals and interfering information. A circle of sound signals develops that generates humming. Heat produces inside the system, and it can damage the external surface of these tools. Few people also complain that their home theater keeps turning off due to this problem.
The amplifier goes through various leaking problems, and the production of hum becomes convenient. The power cables and the audio wires of these tools are separate. The position of the plugs plays a significant role in the production of buzz.
Unheard of reference subwoofer performance for the price and also for its compact size differentiate the... The legacy of making great sound accessible for all continues in the Polk Audio HTS 12 subwoofer. It’s a shoe-in in terms of value, functionality, and compatibility. With its low-frequency tones, it can add dimension, depth, and feeling to what you hear. Gary Altunian was a freelance contributor to Lifewire and industry veteran in consumer electronics.
The control panel is pretty robust, offering volume, phase switching, and crossover frequency adjustment. This makes it possible to create just the right amount of bass for your entertainment setup. This model is a 12-inch front-firing, long-throw subwoofer. And while sound purists opine on whether a long throw sub is possible, the main takeaway here is that it’s designed to immerse the listener in sound instead of clobbering them. Subwoofers are responsible for the bass while speakers are basically electro-acoustic transducers responsible for the amplification of sound. By following the above procedure, you should be able to troubleshoot your subwoofer and find out why it hums when not connected to any device.
You can solve most noise problems in your home theater or multi room audio/video system by taking the systematic, step-by-step approach. Work your way up the signal chain, eliminating each piece of equipment as you go. If you have nothing connected to your speakers except the speaker wiring, and they still hum, the problem is noise induced into the speaker wiring from adjacent power cables. Other than that case, most problems are caused by ground problems, which you can find, and solve, if you take it one step at a time.
You can also contact the manufacturer to replace and install new devices. They also guide about the problems and future preventive measures to reduce humming. A part of it damages, and the connections become vulnerable. The capacitors are essential tools of the amplifying devices. You can hear it with the volume, and it enhances with time. The control of these receivers is a way to decline such issues.
