1. Professional interface microphone with built-in three tone head, high sensitivity, good directivity, low noise, smooth frequency response, clear sound pickup effect, unique appearance is specially designed for engineering installation, and a sponge rubber pad is installed under the solid zinc alloy base, which can effectively eliminate vibration and noise, and can be placed on the desktop or hung on the wall.

2. The microphone has a special hemispherical single directivity, which is suitable for meetings, churches, speeches and other occasions. In order to cooperate with the engineering installation, the microphone uses 9-52V phantom power supply, and the tail end is standard XLR connection, which can be matched with various equipment.
