1. Use high-performance ECM pickup with high sensitivity and wide frequency response.
2. Omnidirectional acoustic technology design, omnidirectional acoustic signals connection
3. Use double-core fully-shielded signal cable to have superior anti-interference ability.
4. Use a signal cable up to 6 meters to be used in various scenarios.
5. Built-in noise reduction circuit design to effectively suppress environmental noise
6. Need no battery power supply individually, and no battery time limit, reducing the maintenance time.
