The MINKEZ's CMC-18 is a conference microphone with new digital design and a speech indication light in the shape of a ring that can show the state of speech. Even without the windproof cotton cover, the precisely constructed microphone shield can reduce the "poop-poop" low-frequency sound. The chairman is not limited by the number of speakers or the microphone modes. The chairman unit has complete control and can be positioned anywhere in the loop. Besides that, the units are connected in a hand-in-hand cascade, making installation and maintenance simple. The microphone pole and professional large heart-shaped condenser microphone core have make the unit a high sensitivity and intelligibility of the speech. CMC-18 also has a T-shaped 8-core cable, two groups of 3.5mm stereo sound output sockets, which can be utilised for recording and connecting earphones, with a built-in hi-fi speaker and volume control, as well as feedback inhibition, and a capability for conversation and automatic video monitoring.
