Detect speaker distortion, noisy sound, quick solution at home.

Speaker distortion when turned up loud is one of the common phenomena when using karaoke audio equipment. However, not all users know how to fix this phenomenon. In the article below, Phuc Truong Audio will share some simple tips to help you fix the above error at home.

1. Reasons why speakers are distorted when turned up loud

• Using speakers with excessive power

With any electronic device, forcing it to operate beyond its capacity will reduce its lifespan and cause many problems.
The same goes for speakers. If you use a small speaker system to play in a large space such as an outdoor stage or a square, it is completely impossible. This action causes the speaker to be constantly distorted and even leads to short circuits and explosions due to operating at too high a capacity.

• Speaker not turned off properly
One of the common mistakes of users after use is to suddenly turn off the speaker by cutting off the power source. This will reduce the life of the speaker and the sound quality will gradually decrease, especially when used continuously for a long time.

• The amplifier is not turned off properly.
Similar to turning off the speakers, suddenly turning off the amplifier right after using the speakers will accidentally make the speakers at risk of lasting noise and more easily damaged in the next uses. This is a detail that few users pay attention to, but is one of the basic causes of speaker noise.

• The speaker is distorted because the user lets the microphone howl for a long time.
A microphone placed close to the speaker will cause sound resonance, causing the speaker to howl. If the user is not careful, causing the microphone to howl repeatedly, the speaker will become distorted or howl for a long time, causing the speaker wire to heat up, causing burning and leading to fire or explosion.
So when the microphone causes howling in the speaker, the user needs to fix the howling error before continuing to use it.

• Uneven Crossover Distribution
Uneven Crossover division is also one of the most basic causes of speaker distortion when turned up loud that most users do not notice. In which, Crossover is a system that divides audio signals by frequency, with the task of processing sound with three frequencies High, Mid and Low. If you accidentally divide these frequencies unreasonably, your speaker system may be distorted and damaged when this lasts for a long time.

• Excessive use of Equalizer
Equalizer (abbreviated as EQ) is a sound processing device before being emitted to the speaker, helping to balance the sound frequencies, especially cutting excess frequencies and increasing missing frequencies. When using the Equalizer too much, the sound emitted from the speaker will no longer be good and of good quality, besides, the speaker is also prone to distortion and boiling when turned up loud.

• Amplifier overloaded compared to speaker capacity
Amplifiers play an important role in adjusting the sound before it is emitted to the speakers, processing and delivering the best sound quality.
However, if the speaker's capacity is many times greater than the amplifier's, it will cause the amplifier to overload and cause noise and damage the speaker quickly.

• The speaker is damaged but still in use.
When the speaker has a problem, customers should take measures to fix it as soon as possible. Do not try to use it, it will only bring a bad sound experience and cause serious damage to the speaker, making it more difficult to repair.
There are also some indirect factors that cause speaker distortion such as: mixer signal and Effect units are overloaded; poor or loose jacks or sockets...; audio signal transmission is near other electromagnetic emission devices such as phones, laptops... affecting the transmission line.

2. Instructions to fix speaker distortion quickly and effectively

To fix the speaker noise and ensure sound quality during use, you can refer to the following methods:
• Use the correct speaker capacity or choose speakers with the right capacity for your needs to get the best sound quality.
• Turn down the volume, bass, treble and then disconnect the power after use.
• Instead of turning off the amplifier immediately, you should reduce the volume and then turn off the amplifier, then turn off other devices and the power source to ensure speaker quality.
• Regularly clean the dust on the speaker and check the speaker cone, be careful when insects get into the speaker.
• Adjust or change the speaker cone when the diaphragm is torn, wet or the speaker cone core is off-center.
• Check the connection between the jack and the speaker. If it is too old, clean it with RP7 anti-rust solution to reduce noise and boiling.
• Rewind the speaker when testing, gently press on the speaker membrane and feel it close.
