Motorola R7 RM780 IMPRES™ Remote Speaker Microphone

The Motorola PMMN4128A IMPRES Remote Speaker Microphone (RM780) is a professional-grade audio accessory designed for demanding environments where clear, reliable communication is essential. Built for compatibility with Motorola MOTOTRBO R7 and MOTOTRBO ION radios, this wired remote speaker microphone allows users to communicate easily without removing the radio from their belt or harness.

The RM780 features Motorola’s IMPRES™ audio technology and a powerful speaker to deliver loud, clear audio even in noisy environments such as construction sites, manufacturing plants and emergency response operations. The integrated windporting microphone helps reduce background noise caused by wind or machinery, ensuring voice transmissions remain clear and intelligible.

Designed for harsh working conditions, the PMMN4128A carries an IP68 rating, meaning it is fully protected against dust and water ingress. The microphone also supports Motorola’s “Work-When-Wet” technology, allowing reliable operation even in heavy rain or wet environments.

With a 3.5 mm audio jack, users can connect a receive-only earpiece for discreet listening, making the RM780 suitable for security, industrial, logistics and public safety applications.
