Turning on and off the sound system correctly has a university question

In daily life and work, the frequency of use of sound is very high, but many links are not well thought out, which can easily cause damage to the sound system. In order to avoid damaging the internal unit structure of the speaker, we need to learn to operate the sound system correctly.

A set of audio system is composed of card holder, equalizer, AV power amplifier, VCD machine and tuner, most of the people are trying to save trouble for convenience, directly plug and unplug the power supply when turning on or off, any electrical appliance will directly affect the internal system unit structure, plugging and unplugging will produce inrush current and reverse peak voltage, most of the damage to the equipment is generated at the moment of turning on or off, so we should pay more attention to the scientific rigor of use.

Nowadays, the audio manufacturing process and technology have become more and more perfect, and the civil audio has gradually become professional, therefore, whether we choose civil audio or professional audio, we must seriously consider its operation, there are three reasons:

1. When purchasing or using audio, it must be combined with the design of the surrounding sound field environment, so as to get better acoustic effects;

2. Acoustic noise, noise or acoustic distortion will affect our hearing, especially in children;

3. Improper operation will shorten the service life of the audio and unit rooms, and indirectly cause economic losses to us.

Therefore, when switching on and off the audio system, we must master the switching sequence of each unit, and turn on the computer in the direction of the sound source signal flow: turn on the card deck, VCD machine, tuner, equalizer, and finally turn on the power amplifier. To put it simply, the correct way to operate the sound system switch is to turn off the amplifier first, and then turn off the other equipment.
