Extreme noise has met its match with the new Kenwood KMC-51M/52W Speaker Mics with advanced DSP Voice Enhancement Technology. Users can eliminate even the loudest background noise for clear, crisp voice communications in any situation.  The DSP signal analysis incorporated into this speaker mic rapidly analyzes the ambient noise and then adjusts to level changes and types of noise.  That means that your urgent communications will be audible with accuracy even in extreme noise environments.  The KMC-51M/52W also is designed so high noise does not overwhelm the digital vocoder and comes with a tactile PTT for easy use, one-touch channel access, a 360 degree swivel clip and noise-cancel active LED.  The microphone operates in analog and digital modes and is MilSpec certified for C-G and IP/54/55 with the IP67 immersion option available on the KMC-52W model.
