Power test method of ktv sound system

　　With the improvement of living standards, there are more and more entertainment activities and places. ktv is one of the entertainment places that customers often go to. The quality of ktv equipment can fundamentally clarify a ktv problem. Ktv audio is the main equipment of ktv.

　　Therefore, many KTV operators are very cautious when purchasing equipment. We all know that when we buy KTV audio, we often choose the one with high audio power. The reason is that the sound power is high and the acceptable power is also high, which is more stable. Even if it is turned on very loudly, it will not be distorted, and it is not simply burnt out; When the power of the stereo is small, it will be distorted if it is turned on a little louder, and it will simply burn out.

　　But how to test the power of the ktv stereo? Wanchang Sound should focus on the planning, installation and protection of sound engineering, such as selling and renting professional lighting and sound, receiving KTV, multi-function hall, banquet hall, conference hall, conference room, public address, bar performance hall, etc. Now let's take a look at the testing methods of ktv audio power.

　　During the test, dance music with weak rhythm should be used for detection. Let's take a look at the specific test method:

　　1. Then switch the PK machine or PK cable to another audio system and repeat the operation we just left. By comparison, we can see which sound is more powerful and which sound is louder and more awe inspiring without distortion. Generally, the sound of high power speakers will be louder, while the sound of low power speakers will be smaller and insufficient. Based on this, we can select more and more excellent professional audio equipment.

　　In fact, in addition to the professional audio power test method introduced above, there is another test method. It can also judge the sound power according to the size of magnetic steel and voice coil. In general, the unit power with large magnetic steel and voice coil must be large, and the unit power with small magnetic steel voice coil must be small. However, this test method is generally not used. If the manufacturer agrees to disassemble the stereo to check the comparison speaker unit when purchasing professional audio, it can be tested and selected.

　　2. First switch the PK machine or PK line to one of the loudspeakers, and then gradually turn the power amplifier volume knob from left to right with your hand after the song rings to hear the distortion of the sound. When you feel a significant distortion, remember the position of the power amplifier volume knob and the loudness of the on-site sound, and quickly reset the volume knob to zero.
