Wired microphone - equipment cheap, stable performance, low maintenance cost, confidential; drawback is more complex construction of the embedded security conference microphone, mobile inconvenient to use. Microphone is a professional speech equipment · noun, it refers to the delegates to participate in the meeting by discussing the voting equipment. Root desktop microphone session MS-M90A / B according to the different models used, delegates can get some part or all of the following features: speech, speech application, receive information on the screen, chat with other participants through the internal communication system participate in electronic voting, simultaneous interpretation system means to receive the original speech language broadcast simultaneously translated into a new language voice messages in other languages ??later. Used for the exchange of international conferences. Use multilingual delegates met together in the process, when used to speak on behalf of any one language by simultaneous translators instantly translated into other languages, language distribution system served by each of the participants before Taipower paperless digital microphone, it can choose to listen to understand their own language, to multilingual communication purposes. The microphone system was discussed at the meeting to increase the simultaneous interpretation system language channel selection function on each device system and a corresponding increase in the following equipment components: Interpreter machine: Let the translator to translate the language of the transferred into the system, let participants choose to listen; language distribution system: simultaneous interpretation system, language distribution system can be divided into a wireless or wired type style; wireless type - can flow use, equipment, space utilization, the disadvantage is expensive equipment, confidentiality not as good as wired type; now more use of infrared wireless microphone system Shure import monopoly, stable performance, infrared microphone can not pass through walls, confidential; wired microphone - equipment cheap, stable performance, low maintenance cost, confidential; shortcomings is more complex construction, inconvenient mobile use. Modern cultural life, many are likely to use wireless microphones occasions. However, people on the selection and use of wireless microphone still have a lot of errors, such as the distance of the microphone to work effectively, people always think of RF power, the more far away from their work can be found in the actual work is often not the case. In addition, the manufacturers release technical indicators, sometimes puzzling. There is no essential difference between the manufacturers of wireless microphones on the principle that many technical indicators product is very good, but the actual use but to no avail. In practice, the technical indicators microphone testing is a problem, because the city does not have a lot of use of units of a full set of radio laboratory measuring instruments, can not be tested for index products.
