Hand in hand conference discussion system (microphone) systems are connected in series with a special line up between all microphone microphone, and finally to the conference host Technica microphones, Shure, like holding hands in general. Ongoing exchange of large group meetings, the meeting many speakers, hand in hand conference system to speak with OLED clock conference units to ensure that everyone is very easy to speak, but also to facilitate meeting management. System generally consists of a chairman to speak machine (controller), speaking on behalf control multiple machines, system components and functions are as follows: Statement by the President microphones: a precedence, voice control and system settings right; each system set a chairman unit ; Vice-speaking microphones: a precedence, voice control; set up a vice chairman of machines per system; speaking on behalf of the machine: a application speeches queuing hear statements function; each system can be set from 5 to 120 speeches Delegate; conference host: accept President machine interface microphone recording microphone instructions on delegate microphone control. Sound system design usually start from the sound field design, because the sound field system is designed to meet the functional and sound basis, involving the selection of a speaker system for sound programs and signaling pathways, such as microphone microphone professional, is very complicated task. Due to the development of computer technology leap, now may be a special acoustic calculation software tools to get to meet the expectations of the sound field design. After the speaker system determines, in order to calculate and determine the driving power amplifier driving signal pathway; then further determine the selection of signal processing solutions and mixer, etc. The driving power allocation scheme. Microphone in the current plays an important role, especially in the growing wireless technology, the wireless microphone has replaced the traditional wired microphones are widely used. Wireless microphone audio signal through a microphone is converted to an audio electric signal, junction capacitance is changed by changing the output frequency of the high frequency oscillator, frequency modulation wave generated by high-frequency amplification and frequency selection, radiated by the antenna. Receiving signals through the receiver and converted into an audio signal can be achieved remotely sound propagation. Compared with easy to use, nice advantage in the process does not require the use of long cables, cable brought out of the poor. With the development of modern science and technology, wireless microphone types become more feature also will become a strong first month of conference microphone microphone microphone _ _ Wuhan congratulate Ram Jiuhua video provided by Wuhan Engineering Limited.
