What are the differences between speakers and speakers
Speaker refers to a device that can convert audio signals into sound. In layman's terms, it means that the main speaker cabinet or the subwoofer cabinet has its own power amplifier. After amplifying the audio signal, the speaker itself will play back the sound to make the sound louder.
Sound system connection plan
Most professional audio systems are composed of unit equipment. After designing the audio system and selecting the equipment to be used according to the requirements of use, these discrete devices should be connected according to the design requirements to form a complete audio system that can meet the design requirements. For a fixed installation system, the equipment should be installed in the cabinet, and all system connections should be fixedly installed in accordance with certain standards and specifications (relevant regulations for building weak current). For mobile systems, such as concerts, outdoor performances and other temporary installations, effective temporary fixation measures should be taken for equipment and cables to ensure their safety. The connection and installation of the sound system involves many engineering issues, including the design and construction of the sound control room, the pipeline engineering of the sound system cable, and the power supply of the system. This section will focus on these engineering issues. The connection of the sound system can generally be divided into three aspects: signal transmission, grounding network and power supply system.
The influence of power supply on audio sound
Ordinary audio players do not consider the power supply in the overall plan of the audio system in their minds. In fact, the performance of the audio system is greatly affected by the quality of the power supply, especially modern high-frequency communication equipment. In the current environment, the pollution of the power supply in the home is becoming more and more serious, which affects the sound performance of the audio system. In order to improve the purity of the power supply, we can consider from many aspects.
