● The conference room sound reinforcement system is a precise scientific system, with stable work, high reliability and other performance. Usually these problems can be troubling, for example, it is easy to howl when the pickup distance is close or far during the meeting; the microphone rod occupies a large space;  and the pickup range is small.

● When setting up the venue, it is impossible for the spokesperson to test the sound on site. Therefore, in order to achieve a bright and clear sound effect (loudness should be just proper but not howling) during live sound reinforcement, there is a certain amount of knowledge that should learn in the selection and placement of microphones.

● Because different types of microphones have different effects on different sound sources, especially the selection of microphones should be an in-depth understanding of the technical characteristics of the microphone, performance advantages and disadvantages and applicable occasions.

● In addition to considering the electroacoustic indicators such as the sensitivity of the microphone, the matching of the output impedance and the input impedance of the mixing console, the directional characteristics, frequency response characteristics and the shape of the microphone should also be taken into account in the conference room.

● In terms of directivity,  the supercardioid model is suitable for fairly long-distance pickup, the cardioid model is suitable for most situations, and the non-directional model is never suitable for speech pickup and is prone to causing echo and howling.

● For this reason, we introduced a wide bandwidth condenser cardioid microphone, microphone using a short microphone pole, high sensitivity design, simple and atmospheric appearance.
