Left right speaker check

Today, most young people can no longer imagine their life without music. To listen to music created a huge number of devices. This is a huge variety of speakers and miniature portable. Fans of games can choose for themselves excellent game devices. Even music lovers can choose their gadgets with sound quality, almost perfect.

Why do I need to check the columns?

As a rule, as soon as the purchase gets into the home environment - there is a need to check it. It is necessary to check how good the sound is, and how it copes with the stereo mode. What is it for? Well, naturally, to make sure that it works. The second point is to determine which one is left and which is right. For what? After all, if you swap them the sound quality will not change and will not be worse!

And imagine the situation that you are playing a game with surround sound or watch a similar film. In such cases, the sound goes to the column, from which direction it goes according to plan.

REFERENCE! In other words, if you swap them, then the sound of a shot going into the game from the right side will be voiced by the left speaker and vice versa. And this is very uncomfortable, and for the player - sometimes even fatal.

How to check the right / left column?

Unfortunately, speakers, unlike headphones, as a rule, do not have an alphabetic marking to indicate the channel. Therefore, to confuse them in places is quite possible. However, do not underestimate the prudence of manufacturers. Each cable coming from the speakers has its own color marking. It is enough to plug the cable into the socket on a computer or other equipment that is painted in the same color so that everything is correct. But it is necessary to take into account the possibility that access to the device is not always free so that you can see the color marking of the sockets. Sometimes you have to connect by touch.

How to make a check in such cases? A standard Windows tool can help. We should find in the bottom right of the screen, so where the watch is located image of the speaker. And through a pop-up call me SOUNDS.
After the button is pressed, a window will appear.

Pay for two speakers. If you press the mouse cursor on the right, then the sound should go out of it. If we press on the left, the sound will be from another. If the connection was correct and both devices work normally, then the sound will be heard in both speakers.

As it became clear that the sound was truly surround and the left and right speakers must be in good condition. There are at least two methods for such verification.

In the first case, both channels are tested with a separate audio signal.

  1. The sound with a certain interval is fed first to one speaker, then to another.
  2. In addition, the signal can move from one speaker to another. If all manipulations with sound are clearly recognized by the user, it means that everything is fine with the device.

A similar technology has already been described above.

It is possible to simultaneously check the speakers.

  1. In this case, an audio signal is simultaneously fed to two speakers, which varies uniformly in volume and frequency.
  2. If the speakers are working, you can hear the same thing both on the right and on the left.

Recommendations

Attention! If there is a desire to check the purchased device for the quality of the output sound, then in no way do it with the help of mp3-files. They, as a rule, are so compressed and repeatedly that it is not necessary to speak about quality. It is better to use flac or wav files.

Numerous Internet services can serve as another way to check the device’s operability and correctness of its connection.

They will allow to make a check, even on the reduced assemblies of the operating system. And it is no secret that at the moment such assemblies, as well as official ones, as well as those created in artisanal conditions, have a great many. And not every assembly on its board has a means to check the speakers. Often this tool is considered unnecessary ballasts and excluded from the composition to reduce the size of the installation file.
