ไมโครโฟนสำหรับประชุม ยี่ห้อ Shure รุ่น CVB-B/O
The black Shure CVB-B/O is a Centraverse Series omnidirectional boundary condenser microphone designed to provide an optimized-for-speech frequency response and discreet desktop installation for presenters and speakers in conference rooms, corporate events, houses of worship, and meetings. The low-profile microphone features CommShield technology to reject RF interference and an attached 12’ XLR cable for compatibility with most mic preamps.
The omnidirectional condenser element yields a frequency response of 70 Hz to 16 kHz, which naturally attenuates low frequencies that are often produced by vibration and rumble. It is powered by 11 to 52 VDC phantom power.
