The sound switch manufacturer will explain some problems about the use of sound.

Audio switch manufacturers: how to pay attention to the use of audio?

Now people's quality of life has improved, the usual way of leisure and enjoyment has become diversified, not only the visual comfort, hearing is also required, so many people at home to place audio equipment, experience different auditory pleasure, how to buy audio?

　Audio switchManufacturer: How to buy stereo

1. Confirm the shape, color and size of the sound

The choice of audio starts from the ordinary type, and the multimedia active sound with smooth shape, fine and uniform tone gives people a feeling of heartbeat first. On this basis, carefully investigate whether the joints of the audio box are uniform and tight, and whether the shapes, adjustment knobs and function keys, and the positions of the jacks are reasonably distributed.

2. Feel the sealing performance of the sound

At present, most multimedia active audio systems adopt reverse phase type. There are holes called reverse phase ports on the audio. The higher the tightness of the audio, the better the sound effect. To check this indicator, please put your hand close to the reverse phase port in the audio operation. When the sound is drum sound or explosion sound, the reverse phase port must have obvious air flying out or inhaling. It feels like wind. The tightness of the audio seems very high, the tightness directly affects the low frequency response index of acoustics.

3. Whether the audition sound is naturally balanced

The sound of the person's voice and instrumental music should be as close as possible to the original sound, not too collapsed, the sound heard should be smoothly and silently dyed, not too strong and weak sounds (peaks and valleys) should be heard, the intermediate frequency and treble should be avoided too much and breath-holding away, the instrumental music (such as piano music) with a larger frequency range should be recorded and placed, and attention should be paid to the changes in tone and color when listening to low, medium and high scales.

　　Audio switchManufacturer: What should be paid attention to in the use of audio

1. Before turning on/off the audio power supply, turning the volume of the amplifier to the minimum is the most effective means of protection for the amplifier and the speaker. At this time, the power amplification of the amplifier is almost zero, at least it will not cause harm to the speaker during misoperation. When reseating the power cord, it is best to cut off the power supply and reseat.

2. The normal working temperature of audio equipment must be between 18 and 45. Too low temperature will reduce the sensitivity of some equipment such as electronic tube machines. Too high will cause parts to burn or age in advance. In summer, pay special attention to cooling and maintain air circulation. Audio equipment must avoid direct sunlight and do not approach heat sources such as heating.

3. It is also very important to prevent signal overload. Correct signal size control is very important to the service life and sound effect of the equipment. The overload range is mainly manifested in whether the signal is distorted and the signal control when the equipment is powered off. Most equipment has a signal overload indicator, but generally the indicator light is red to indicate signal overload. Whether the red light is intermittently lit or always lit, please handle it.

　　Audio switchManufacturer: When buying a stereo, please observe the shape, color and size of the sound, feel the tightness of the sound, and then try whether the tone is natural. When using audio, please pay attention to reduce the volume to a minimum before turning off the power. The working environment temperature of the stereo should not be too high. In addition, please avoid direct sunlight and deal with it immediately when the audio signal is overloaded.
