NMN6271A NMN6271 - Motorola APX XP IMPRES Remote Speaker Microphone, IP68 -- Designed with mission critical users in mind, the NMN6271 APX™ XP Remote Speaker Microphone (RSM) suppresses noise so effectively, you can be heard over traffic noise, crowds and sirens. Its unique dual-microphone design tracks the talker’s voice so that you can keep your eye on what’s in front of you while still talking on the microphone. A digital signal processor (DSP) algorithm helps suppress background noise so you can be heard clearly regardless of the noise around you. Includes a flexible 360-degree rotatable shoulder clip, designed specifically to fit comfortably on the police uniform epaulet. A D-ring provides an additional attachment option. This IMPRES RSM is the thinnest in the APX portfolio and is specifically designed for tough mission critical use — buttons are enlarged for easy access, yet recessed to avoid accidental activation. The NMN6271 is completely submersible when attached to an appropriately configured APX portable radio. Available with 3.5mm threaded jack in NMN6274 model.
