Why are the columns wheezing? How to remove unpleasant wheezing from a column

Speakers and speakers have been designed specifically to enhance the sound volume and improve the quality of the main speakers. They are used when connecting to large concerts, holidays, and even in home theaters. To get the desired quality, you must correctly select the model of the device and the manufacturer's company.

Sometimes during operation unpleasant malfunctions in the system or malfunctions in the electronics can occur, leading to a deterioration in the quality of the displayed melodies. One possible problem is the characteristic wheezing in the columns. It interferes with playback and creates unpleasant interference. In our article, we will talk about possible causes and advise how to restore the normal functioning of the columns.

Reasons and solutions

Before starting work, it is necessary to identify the source of the problem and assess the complexity of the damage. In case of malfunctions, you can repair the equipment yourself, in case of more complex violations it is recommended to contact a specialist who will assist in the repair of the device. Here are some common wheezing problems:

• Mechanical damage to speakers or connected wires.
• Violation of the electronics and microcircuits of the device.
• Moisture and other foreign objects get inside the case.
• Mismatch of connected equipment with speaker capabilities.
• Improperly selected amplifier.
• Wear and poor speaker performance.

Depending on the cause, the repair and troubleshooting algorithm will be different. With mechanical damage, it will be necessary to eliminate the defect or replace parts of the case, and in case of failures in the electronics, detailed diagnostics and restoration of the operation of microcircuits and boards will be required.

IMPORTANT: When you save the warranty card, you will be provided with free diagnostics and equipment repair. In order for the warranty card to maintain its validity, you can not do it yourself.

Wheezing and hissing of speakers

Most often, users encounter problems in the performance of low-quality speaker systems. The most pronounced malfunctions are manifested by a characteristic wheezing, which interferes with listening to audio recordings. If you encounter such an unpleasant situation, it is necessary to evaluate the condition of the equipment point by point and in accordance with the instructions carry out repairs and adjustments to ensure normal operation system.

First of all, check the correspondence of the connected equipment and the range of speakers.

IMPORTANT: Perhaps the system itself is outdated or poorly built, buy proven devices in company stores.

When outputting sound waves through any speaker, a special amplifier is used. It receives a signal and transmits them to the speakers. Two main indicators of the operation of this device are distinguished: the output power of the signal and its resistance to the incoming load. If you install an inappropriate amplifier, the sound will not be output or distorted. At the same time, specific wheezing appears in the work.

TIP: Check the speaker parameters and purchase the appropriate amplifiers. Consult your dealer for more information.

How does it wheeze?

An interesting way to diagnose is to evaluate the nature of wheezing. Listen carefully to your technique and evaluate the distortion parameters by the following parameters:

• Temporary indicators: constantly wheezing or a certain time after switching on.
• Symmetry on both speakers or malfunction on only one speaker.
• Depends on the power, frequency and volume level of the playback sound.
• The presence of wheezing at close proximity to telephones and other electrical appliances.

This will help to detail the source of the problem and roughly understand the nature of the malfunction for further diagnosis and repair. We will analyze the possible options and frequent cases of hissing and wheezing.

Both speakers wheeze. In modern equipment, a situation where both speakers work poorly at once is extremely rare. Manufacturers are trying to improve the quality of technology and introduce advanced technologies and developments in their products. However, if you encounter a similar situation, most likely the reason is the output device sound (receiver, set-top box, radio ...), because the failure of several speakers at once happens quite seldom.

To clarify, try connecting the speakers to another source. If the problem persists, then you need to repair the radio or purchase new equipment.

Hoarse one at a time. The situation is different with the poor performance of one column. In this case, we can talk about malfunction of the speakers, damage to the wires, improper calibration of the frequency and resistance of the amplifier. If both speakers are from the same manufacturer and the same model, just try to set all the parameters equally on both speakers.

With different versions, the source of the problem should be accurately identified. To do this, connect the system and listen to music at different volume levels.

IMPORTANT: The nature of the damage depends on the volume level at which wheezing appears.

Wheeze at minimum or maximum volume

Start checking at low volume. If wheezing appears, then the problem is connecting the wires to the speakers. Most likely they are moving away or damaged. To do this, you have to disassemble the equipment and see the internal components.

If everything works well, continue to increase the volume. When wheezing occurs at high volume, the following types of problems are possible:

• The ingress of large particles of dust or dirt can cause vibrations and sound disturbance.
• Water inside the speaker enclosure causes the wiring and microcircuits to leak, which also contributes to hissing.
• Problems with a capacitor that incorrectly outputs the amplitudes of sound waves.

IMPORTANT: Before starting the repair, check that the problem is in the column, and not in the receiver.

Recommendations

So that in the future you do not have any problems when operating acoustic systems, preventive measures should be taken and the operating conditions of the equipment should be observed. It is enough to follow some rules:

• Periodically check the connection of the wires and monitor their integrity.
• Do not allow dirt or moisture to enter the speakers of the equipment.
• Make sure that the speakers and all device microcircuits are connected correctly.
• Perform preventive cleaning of equipment.

Simple rules that will help extend the life of your equipment and allow you to enjoy high-quality and rich sound.
