里摆放诸多音频设备中，很多人对音响电源时序器并不了解。其实音响电源时序器就是用来控制音频设备的敞开或封闭的时序器，按照由前级设备到后级设备逐一次序启动电源，封闭供电电源时则由后级到前级的次序封闭各类音频设备，是音响工程不可或缺的设备之一。
Many people don't know about Audio Power Sequencer among the audio devices placed in vito cabinet. In fact, the audio power sequencer is used to control the opening or closing of audio equipment. It starts the power supply one by one from the front equipment to the back equipment. When the power supply is closed, it closes all kinds of audio equipment from the back to the front equipment. It is one of the indispensable equipment in audio engineering.
在音响设备体系正常敞开封闭中，开机次序是先开前级音频设备如麦克风、调音台和效果器等，然后开后级设备的功放。关机次序则相反，先关后级音频设备功放（注：这样能够避免电流对前级设备发生的噪声冲击、损坏音箱及功放），再关前级音频设备。
In the normal opening and closing of audio equipment system, the starting order is to turn on the front audio equipment, such as microphone, mixer and effector, and then turn on the power amplifier of the latter equipment. On the contrary, turn off the power amplifier of the second level audio equipment first (Note: this can avoid the noise impact of the current on the front level equipment and damage the speaker and power amplifier), and then turn off the front level audio equipment.
如果采用电源时序器，接入不同音频设备开关接口，就能完成由前级设备到后级设备，逐一按次序敞开或封闭电源，有效管理和控制各类音频设备，避免人为的失误操作引起音频设备受损。
If the power sequencer is used and connected to the switch interface of different audio equipment, the power supply can be opened or closed one by one from the former equipment to the latter equipment in order to effectively manage and control all kinds of audio equipment and avoid the damage of audio equipment caused by human error operation.
大型活动运用的音响体系，由于有调音团队存在，能够熟练地运用音频设备，电源时序器对于他们来讲是可有可无。
The audio system used in large-scale activities, due to the existence of professional tuning team, can skillfully use audio equipment, power timing device is dispensable for them.
但在会议训练室、KTV文娱场所、家庭文娱客厅、公共广播等场景运用的音响体系中，由于缺少调音师操作，现场的运用人员大多调试操作不标准，这就需要配置电源时序器，以便运用人员轻松管理和控制音频设备敞开与封闭。
But in the audio system of meeting training room, KTV entertainment place, family entertainment living room, public broadcasting and other scenes, due to the lack of professional tuner operation, most of the on-site users do not have standard debugging operation, which requires the configuration of power timing device, so that the users can easily manage and control the opening and closing of audio equipment.
