SM9WELNC Microphone
SM9WELNC – Full Size, Heavy Duty IP67 water & dust proof, Active Noise Cancelling Speaker Mic., 3.5mm earpiece port, Emergency Button, Long Cable
- IP67 Rated Water & Dust Resistant up to 1 meter
- Duel Active Noise Cancelling
- Dual-Core DSP Chips with Noise Reduction Algorithms – PI-36 is a digital DSP long-distance pickup and noise reduction module. It can clearly extract human voices in a noisy environment and suppress environmental noise. The PI-36 module integrates a dual-core DSP chip with a unique and efficient noise reduction algorithm, which is effective for both steady-state and non-steady-state noise.
- Wind Protection Duel MEMS Microphone – MEMS microphones have an amplifier unit inside and generally have 3 wires: ground, power and audio output. Compared with condenser microphones, MEMS microphones can obtain very stable signals with high signal-to-noise ratio and good consistency.
- Spark Guard Metal Spark Proof Speaker – protection from hot metal shavings
- 4.9 mm V-O Rated Flame Retardant Cable – Burning stops within 10 seconds on a vertical part allowing for drops of plastic that are not inflames
- 3.5mm Audio Port
- Heavy Duty Clip with Hanging Ring
