Knowles offers boom microphones that utilize magnetic microphone elements. These elements generate their own signal and, unlike traditional dynamic microphones, do not require a bias voltage. This feature can be helpful to ensure compatibility with radios. BJ-based boom microphones have been chosen over dynamic microphones to upgrade performance and reliability for military and first responder applications.
- Robust reliability and high performance
