Description
The BM-112 microphone is designed for ceiling installation. The BM-112 interface microphone is designed for ceiling or desktop mounting and is suitable for telephone/video conferencing, audio recording or round table discussion amplification and where the microphone needs to be hidden as much as possible. The terminals for both phones are mounted on a standard base case and use a 1-gigabyte panel. The BM-112 is widely used for telephone/video conferencing, choir performance, distance learning and any application requiring high quality voice or music playback/recording. All microphones have good rf shielding effect and can effectively isolate rf interference from various wireless communication devices (such as mobile phones).
Functional Features
- Multipurpose installation – For fixed or suspended ceiling installations.
- Pointing feature – BM-112 hemispherical directivity characteristics.
- Microphone gain – High gain before feedback.
- Anti-interference – Good RF shielding effect, effectively isolates RF interference.
