How to Eliminate Hum in an Amplifier

Cara Menghilangkan dengung Pada Amplifier

An amplifier or often called a loudspeaker is a device that can produce stereo sound to produce much higher and clearer sound quality. We usually encounter amplifiers at entertainment events, social events, religious events and so on. Small examples of frequently used everyday amplifiers are watching TV, radio, playing music, and Toa.

Amplifiers are often used to convey announcements in the community, giving the call to prayer for Muslims and others. There are many functions and benefits obtained by using this amplifier for various human needs.

However, apart from this, it turns out that the amplifier often experiences buzzing, this sound causes an effect that is very painful to the listener's ears. Usually self-assembled amplifiers tend to emit a buzzing sound like noise that is very high. Often this problem is caused by the assembled amplifier, if the assembly process is not correct then noise or hum problems will occur, this problem often arises and is a common occurrence.

For this reason, for those of you who assemble amplifiers, it's a good idea to always pay attention to the procedures and components used so that this doesn't happen.

Various Causes of Assembled Amplifier Buzzing Noise

In various cases, assembled amplifiers often experience humming, there are many causes, see the summary below.

1. Ground is not good

One of the main causes is poor ground, this cause can occur but usually the hum produced is not too loud, apart from that it does not cause the buzzing effect to become loud if the volume is increased. Therefore, if you want to assemble an amplifier, it is better to use components whose quality is truly guaranteed.

2. Power Supply Circuit

The second cause can be caused by a poor power supply circuit which causes the buzzing sound to become loud when the amplifier volume is increased, this is caused by the Elco or transistor being worn out so that the electric current cannot run properly. The electric current from the Elco output must be the same as the electric current issued by the transformer, this is so that the incoming electric current is balanced and prevents buzzing from occurring. If the Elco is hot then there is an energy imbalance, therefore use a power supply whose quality is truly guaranteed. However, if the Elco or transistor experiences a leak or is damaged, it must be replaced by purchasing new, higher quality components.

3. Input cable problem

The input cable is a connector from the input source to the output source in the form of signal transmission. Good quality input cables can be characterized by copper fibers that protect the ground side. This input cable will be connected directly to the mic and then the signal will be given to the amplifier, but this item should not be used close to the transformer because it will produce a buzzing sound so it is very shrill, generally this is what makes the amplifier buzz but cannot produce sound. This is due to the electromagnetic attraction on the head of the item.

For those of you who want to check the condition of the item, whether it is still normal or not? You can check by touching the cable insulator or plastic. If a hum occurs, it is certain that the object is very easily disturbed by frequencies from other sources. Apart from that, if the input source is not installed in the perfect position, this problem can arise.

4. Amplifier box is not optimal

When choosing an amplifier, of course you have to choose it carefully and not haphazardly, this is because the amplifier plays an important role as a ground so that it can prevent electromagnetic waves from the transformer so that it doesn't cause a buzzing or screeching sound. One way that can be done is to use an amplifier made of aluminum or iron. Apart from that, the ground supply must be installed perfectly and according to specifications so that it is suitable when connected.

How to Eliminate Huming Sounds in OCL Cables

The following are ways you can overcome the hum caused by the OCL cable, see the complete information below.

1. First Way

The first thing you can do to overcome the hum in the amplifier is to switch the cables, this is a simple way to prevent the cables from becoming chaotic so that you will be safe from the risk of damage to the cables.
