A radio is only as clear as its microphone. The Motorola PMMN4128 remote speaker mic makes sure wind, noise, and rain do not decide what dispatch hears.
IMPRES Windporting: Voice That Cuts Through Wind
Wind noise is the silent killer of radio intelligibility. The Motorola PMMN4128 uses IMPRES Windporting to channel air away from the mic element, suppressing the roar that buries speech. A police officer calling from a roadside in a storm, a port worker on an open dock, or a rail crew beside a passing train stays intelligible. This IMPRES Windporting noise cancelling mic does not just make calls more comfortable. It makes them actionable. Dispatch hears the address, the number, the request, the first time.
HD Voice Hardware and Bluetooth 5.0: Built for the New Flagships
The RM780 is designed around the R7 and APX N series, and it shows. HD voice-ready hardware pairs with the radios’ high-definition audio path, keeping full fidelity from mic to speaker. Bluetooth 5.0 connects a wireless earpiece, so a user can go covert or hands-free while the mic sits on the shoulder. The 3.5mm jack adds wired audio options. This Bluetooth 5.0 IP68 shoulder mic bridges the gap between a loud public speaker and a private, discreet earpiece, switchable on the job.
IP68 and a Glove-Friendly PTT: Field-Ready by Design
Field gear meets field conditions. The PMMN4128 is sealed to IP68, matching the R7 and APX N radios it serves. Rain, dust, and submersion do not end a shift. The large PTT button gives tactile feedback through gloves, and volume controls sit where a thumb finds them. The 12-inch cord positions the mic on the shoulder or collar without dangling. From R7 patrols to APX N30 industrial crews, this PMMN4128 RM780 R7 speaker mic is the interface between the radio and the real world.
