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.
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.
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.
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.
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.
