The traditional sound reinforcement system is composed of a sound source and its acoustic environment, a mixing station, a power amplifier, speakers, and their acoustic environment. It mainly includes the sound source and its surrounding sound environment, microphones that convert sound into electrical signals, equipment and transmission lines that amplify signals and process them, speakers that convert signals into sound signals, and the acoustic environment of the audience area. The sound reinforcement system in traditional conference rooms is very complex, so we can see that general conference rooms have many devices. Before wireless microphones were widely used, the conference table was often densely packed with poles and wires, which was unusually messy.
Not to mention the space occupied by equipment such as cabinets, if there are equipment issues during a meeting, maintenance is also a significant task for the staff. After the emergence of the insensitive sound reinforcement system, this situation has been greatly improved. The insensitive sound reinforcement system is mainly composed of an intelligent audio host, a suspended microphone, and a sound system, which is very simple. The intelligent audio host adopts a professional DSP audio processor, and the audio debugging, central control communication, recording and broadcasting host and other systems are highly integrated. It integrates multiple algorithms such as intelligent mixing, automatic noise reduction, and reverberation elimination, and is controlled with one button to achieve clear and stable sound reinforcement. It completely replaces the sound mixer and greatly saves space in the conference room.
In addition, the combination of hanging microphone and intelligent host can well meet the application of language reinforcement and meet the dynamic requirements during meetings. The hanging microphone can pick up sound in a wide range from afar, and after being processed by the intelligent audio host, the sound pressure level is moderate, the dynamic range is large, the sound field uniformity is good, the sound quality is beautiful, and the language is pleasant. Smart sensorless system has now become a mature audio technology, with a certain degree of progressiveness, integration and reliability. Under the strong momentum of scientific and technological development, it can be combined with recording, broadcasting and remote video conferencing to meet the needs of enterprises for conferences.
