What to do when karaoke microphone is howling?

During the use process, surely you will inevitably at times karaoke microphone howling very uncomfortable. So what causes that phenomenon? And how to handle them? Read this article to get an answer.

I. Causes and ways to overcome karaoke microphone howling

1. The cause of the howling of a microphone

Here are some reasons why microphones are howling while using:

a. Microphone position facing straight and near speaker

Leaving the microphone straight and placing it close to the position of the speaker is also a cause of the microphone being howled. When you sing, the microphone records and emits a loudspeaker, unintentionally the sound coming from the speaker is recorded by the microphone and amplified exponentially. So creating so many cycles, causing the microphone to be howled.

b. Sound resonance appears

The resonance frequency is also related to how the microphone is howled. Every object, room area, design in the room also has the ability to echo the sound when the speaker emits, causing the microphone to collect a lot of noise, leading to a howling sound.

To visualize this cause you can think of how you apply a snail (small and small in size) to your ears and hear howls.

c. Micro is missing capacity

Micro capacity is not enough to meet the needs of users also causes the microphone to be howled. In other words, the audio signal is not in the Headroom reserve and reaches the Clip level, causing the sound to be distorted and howling.

Note:

Headroom: As a term in sound system installation, it means that the distance between the normal signal and the maximum signal in the audio system.

If the signal runs out of Headroom and reaches the maximum signal level, it is called a Clip, which causes the microphone to be howled because the sound is distorted.

d. Amply lack of capacity

In particular, amplifiers and amplifiers in general, without power, will make the speakers work with insufficient volume and also generate howls.

e. Micro vents are blocked

When the microphone is howled, you should not ignore the possibility that the vent is being sealed, so the resonant sound occurs inside the microphone body.

f. Operation to hold the microphone is not correct

The howling microphone can be caused by the person accidentally letting his hand cover the antenna of the wireless microphone. Not only that, but placing a microphone close to the mouth also causes a howl.

g. Amply tuning is not correct

This is also the reason why microphones are howled. If the amplifier is not properly tuned, the microphone will appear howling. In addition, in some karaoke amplifier does not support the elimination of howling, so the situation of howling microphones appears.

2. Keep mouth and microphone distance reasonable, so that no howls will appear.

Micro is missing capacity

2. Adjust the sensitivity of the microphone so that it catches its own sound when emitting a loudspeaker so that no howls will appear.

Amply tuning is not correct

1. Adjust amly accordingly.
2. Can choose to buy ampy types that support howling.

Amply lack of capacity

1. It is necessary to pay attention to the technical parameters of speakers and power amplifier (called power amplifier) ​​such as capacity, sensitivity, impedance to make the sound system to avoid howling, hissing.

In addition, additional support devices can be used to amplify audio signals such as phase regulators, frequency shifters, etc.
