Columns can begin to publish extraneous noise and crash over time. It can appear from time to time or sound constantly. To get rid of this unpleasant phenomenon, it is necessary to find problem source.
The crash reasons in columns
Extraneous noises in columns can be caused by various reasons. It can be fault of the equipment, problem with the software or influence of foreign hindrances.
Quite often the problem is in bad contacts. If there was chafing of wire, the connector on the body of the sound card or the audio system has become loose, even insignificant stir of cable will lead to unpleasant crash.
Washes with the reason to serve also the powerful electric equipment working near columns. Sometimes the speaker system is influenced by hindrances in current network. It can be the working fridge or even the neighbor with the perforator doing repair.
How to get rid of crash in columns
Successfully to solve this problem, you need to localize fault. For a start try to rotate the loudness regulator. If at the same time from columns the notable crash reaches, it speaks about need to replace regulator resistors. If you are not sure of the forces, it is better to address the expert. Most often the reason of crash is in wires and connectors. Cables sometimes are exposed to sharp breakthroughs that leads to rupture of veins or damage of plug pins. The easiest way of diagnostics is to move wire. If at the same time the crash amplifies — you on right way. Pass on all length of wire, it is accurate it bending and unbending. The place of failure of veins will have an effect especially strong noise, or even full loss of sound. Having found such place, cut the damaged site. The free ends of veins need to be smoothed out, zaludit solder and to solder accurately. For isolation it is convenient to use thermoshrinkable tube of suitable diameter, putting on it the free ends of wires before their connection. Having soldered wires, pull thermoshrinkage over the bared sites and heat it the soldering iron. If the wire is intact, try to move accurately the plug in the connector. The weakened contacts will prove crash. The faulty connector needs to be sorted and turned in. If the problem is in the plug, it is simpler to replace it. For this purpose it is necessary to cut off it from wire and to solder new on its place, observing the color scheme. Other electric devices can sometimes become the reason of crash. For example, the powerful desk lamp standing closely to columns. Or the Wi-Fi-router placed on subwoofer in which body the amplifier is mounted. In that case it is necessary to remove source of hindrances far away from columns. One more possible source of crash in columns — hindrances in the power supply network. Such noise often has incidental character and can change the frequency and amplitude. For fight against such hindrances it is necessary to use the high-quality surge filter. If your columns are connected to the sound card of the computer, the crash can arise because of problems with drivers. Try to establish the freshest version available to your equipment. If you use the built-in sound adapter, and at you on the motherboard the system speaker is connected (PC Speaker or PC Beep), it is necessary to disconnect it in the OS settings. For this purpose come into "Control panel" and choose "Sound". On the Reproduction tab right-click on the Loudspeakers point and choose in the appeared Properties menu. Come into the Levels tab and disconnect the system speaker, having removed tick opposite to the necessary point. The biggest problem — fault of the equipment or problem of compatibility. The sound card can break and generate hindrances. In that case its repair or even replacement will help.
