Is a power sequencer indispensable in professional audio systems?

What is a power sequencer? It can be easily understood as a device that starts or shuts off output according to the internal control circuit of the machine equipment, and carries out power supply system management methods for power supply voltage and load machine equipment according to the clear program flow. It can accurately monitor the working voltage, and the volume is getting smaller and smaller. It can regulate the sound card rack from 1U to 3U, with key channels including 8, 10, 12, 16, etc. Widely used in automatic control systems, broadcasting and television systems, speaker broadcasting programs, power distribution equipment and other systems.

Power sequencer is essential in professional audio systems

In audio equipment, the appropriate shutdown procedure is to first turn off the amplifier, then turn off the exciter, frequency divider, mixing console, and other front machine equipment in sequence; The order is reversed during startup. The amplifier should be turned off first to avoid noise impact and damage to the sound system and amplifier caused by turning off the front equipment. By selecting a power sequencer and connecting it to different power switch sockets, it is possible to sequentially turn on the power from the front machine equipment to the back machine equipment. When turning off the power supply system switch, the reverse direction is used. Reasonable and unified management methods and manipulation of various power consuming machine equipment are used to prevent human error in actual operations, reduce the impact of the power switch on the power grid of the power supply system, and ensure the stability of the power consumption system.

If in some fixed and immovable places, such as large and medium-sized exhibition halls or performing arts activities, all systems are actually operated by technical professionals, sound engineers or operators can skillfully use sound equipment, and can completely avoid the need to use sequential power switches. After all, the more simple the system is, the lower the incidence of common faults is. Even when using a sequencer, its function is still relatively powerful, such as being able to perform multi-level cascading, CUP manipulation, and complete computerized management methods. Its reliability and output power capacity are also relatively large. Therefore, in a certain practical sense, sequential power switches are more suitable for beginners.


In the vast majority of venues, such as corporate conference halls, music background systems, karaoke international business venues, mid to low-end bars, smart home systems, fixed installations in large, medium and small exhibition halls, slow shaking bars, and other speaker systems, there are very few technical sound engineers in actual operation. Some systems, such as stage cars, mobile performance sound systems, and university public broadcasting systems, also use part-time management methods to apply machine equipment. The standardization of actual operation is not strong, so it is necessary to add moderate timing power management methods, so that users can have a stronger grasp.
