In modern conference systems, the technical specifications of the chairman unit/delegate unit microphone play a vital role in the quality of conference sound. These technical specifications not only determine the clarity, fidelity and coverage of the sound, but also directly affect the auditory experience of the participants and the overall efficiency of the meeting.First, the sampling rate is an important indicator of the microphone's ability to capture sound details. A high sampling rate means that the microphone can record the waveform of the sound more accurately, thereby restoring a more realistic and delicate sound. For example, some high-end chairman unit microphones use a sampling rate of 48KHz or higher, which is much higher than CD sound quality, ensuring that every speech in the meeting can be recorded clearly and accurately.Second, the frequency response range determines the range of sound frequencies that the microphone can capture. A wide frequency response range means that the microphone can capture more sound details, including the depth of the bass and the brightness of the treble. This is crucial to ensure that the speech content in the meeting is fully and truthfully conveyed. For example, some high-quality chairman unit/delegate unit microphones have a frequency response range of 40Hz to 18KHz or wider, covering most of the sound frequencies that the human ear can hear.In addition, sensitivity is an indicator of the microphone's ability to respond to sound. A microphone with high sensitivity can capture weak sounds more easily, but it may also increase the interference of background noise. Therefore, when choosing a microphone, it is necessary to weigh the relationship between sensitivity and noise suppression. Some advanced chairman unit microphones use built-in DSP audio processing technology to effectively suppress background noise and "puff" low-frequency impact sounds while maintaining high sensitivity.In addition to the above specifications, the microphone's directivity, signal-to-noise ratio, maximum sound pressure level and other technical parameters also have an important impact on the conference sound quality. Directivity determines the microphone's sensitivity to sounds from different directions, which helps reduce interference from sounds from the sides and rear. The signal-to-noise ratio measures the ratio of sound signals to noise signals in the microphone output signal. A high signal-to-noise ratio means clearer and purer sound output. The maximum sound pressure level determines the maximum sound pressure that the microphone can withstand, which is of great significance for preventing sound distortion and protecting the microphone from damage.In summary, the technical specifications of the chairman unit/delegate unit microphone have a profound impact on the sound quality of the meeting. When choosing a microphone, it is necessary to comprehensively consider various technical specifications and actual needs to ensure that every speech in the meeting can be clearly and accurately conveyed to every participant.
