PMMN4071

This RSM features IMPRES technology, which enhances audio quality by suppressing ambient noise, improving voice intelligibility, and amplifying quiet transmissions. This Remote Speaker Microphone with Windporting technology allows you to communicate clearly even in inclement weather. Windporting reduces the whining and howling sounds of wind blowing across your remote speaker microphone while also preventing water from clogging it, resulting in clearer transmissions. This RSM has intrinsic safety approvals to TIA4950 and can be used in hazardous environments. This RSM also has a 3.5 mm audio jack, so you can connect a receive-only earpiece for discreet communication.
