When your speakers are having problems, do not think of bringing the speakers to the service station. The advice is to check each of the components in your system such as connection wires; devices such as Mixer, Main Power, Equalizer, Crossover or any other peripherals belong to your sound system. This test will take time and interrupt your program because the speaker has some fundamental errors that you can thoroughly check and fix in the free time. This article will introduce 9 common issues when using speakers and some ways to check the stability of the speakers.
9 Common Issues when Using Speakers
1# You often create long howls by the microphone
When the loudspeaker emits a howling sound, this is a sign of severe damage to the speaker. The more loops appear, the more likely the speaker will be damaged. A howling in the treble speaker for 5 seconds is about 10 times the heat of the loudspeaker. When the howling is coming out, the windings of the loudspeaker will generate heat very quickly. Because of the rapid heat build-up, they do not even get out of the surrounding environment and create a scent.
#2 Dividing crossover inappropriate
Crossover is a highly important part of every speaker system. They are responsible for providing the standard frequencies for each part of the scheme. If the crossover for mid or treble is too low / too high, then all of these can produce poor sound quality. You should always check the specs of the loudspeaker when you want to divide the crossover.
3# The speaker system does not have enough power to meet your needs
You have opened the full capacity of the amplifier, but you only have 2 pairs of speakers for a stadium of 20,000 people. And you want to achieve high efficiency? As such, it will quickly burn all your speakers! So choosing the right and sufficient power for your entire speaker system is important. This will meet the needs of loudspeaker operation and excellent protection for the speaker system. You will host a program of the highest quality.
4# The use of EQ has exceeded the allowable level
Some people are used to installing EQ in bird form, which is not okay for your speaker system. When you want to decrease treble, bass, and boost mid, this will overload the midrange of your speaker system. And in fact, you do not have enough volume you need. Always keep in mind that EQ is often used to cut the residual frequency band, and EQ is not supposed to increase the bandwidth. For example, You want treble, so you should take a bit of bass (do not increase the treble). And if you want to increase the bass? Do the opposite. Forcing the speakers to run in excessive frequency will reduce the quality of sound. The sound will not be as standard and intact as you would like.
5# Using of Compressors / Limiters incorrectly
In fact, this is a problem that exists and is important when using speakers. Com / Limiters are used by speaker protection. And if you use the wrong function, it will damage your speakers.
6# Your amplifier is overloaded
If main power has to work too much, this will damage your speaker system. Your audio is distorted, and this may even cause a fire, broken speakers or your main power. You can not use a loudspeaker with a capacity of up to 2000W but with a mains capacity of 500W. Choosing the right level of power for the amplifier and speakers, this is critical. Because it contributes to making your system operating in the most optimal environment.
7# You make sudden big bangs
We should follow the principle of operation, which is to open the device in top-down order. And when you turn off then in order: bottom up. In particular, you avoid actions such as pulling wire, touching the wire, or dropping the microphone. These are things that cause loud noises while the sound system is working. It will ruin your speaker system easier than ever. To be safe in the open, we should use a sequential power supply. This job is simple, but it is extremely useful and contributes to improving your sound system.
8# The overloaded of Mixer signals, effect sets, and EQ set
You must adjust Gain. This is related to the quality of the sound, and you are very careful not to fall into the phenomenon of clipping (or peak, or overload). These signal lights are usually located next to the red lights of power. Overloading of the signaling system causes distortion. You need to avoid this bad situation if you need a high-quality audio system.
9# Continuation of the using broken speakers
If you hear a faint sound or an uneven amount of music, it is best to check the speaker before using it again. If you notice instability of the speaker system, then you should have the option to fix the problem. The repairing will help the speaker system stay stable, and it will also improve the sound quality of the speakers. Programmers need to have additional speakers, prepare to replace when occurring the problem.
How to Check The Stability of The Speakers
The problem of the speaker will manifest in the hardware of the speaker. Here are ways to help you check the balance of the speakers.
- Checking the speaker by pressing lightly and smoothly into the diaphragm. You need to realize the existence of space behind the diaphragm.
- Checking the friction between the cone of the speaker wire and the core of the magnet.
- Checking the connection between the diaphragm and the cone, between the diaphragm and the spider of speakers.
- Checking for the presence of insects in the cone of speakers.
- Checking the connection between the station of the speaker to the diaphragm.
