Motorola PMMN4170A (RM560) IMPRES Windporting Remote Speaker Microphone
IP67-rated, AI noise suppression, and Windporting technology for clear communication in wind, rain, and high-noise environments.
The Motorola PMMN4170A, also known as the RM560, is a large IMPRES remote speaker microphone engineered for professionals who demand audio clarity in the harshest field conditions. Its signature Windporting technology eliminates the howling and whining distortion caused by wind — a common failure point of standard RSMs in outdoor operations. Combined with AI-trained noise suppression, the PMMN4170A ensures your voice is transmitted and received clearly regardless of ambient conditions.
Rated IP67 for complete dust protection and water immersion resistance, the PMMN4170A is built for “Work-When-Wet” operation — it continues to function even when submerged. A 101 Phon loudness rating delivers powerful audio output audible over machinery, traffic, and crowd noise. The low-profile swivel clip secures the mic to a shoulder epaulette, vest, or jacket lapel, while the 3.5mm threaded audio jack supports a listen-only earpiece for discreet monitoring.
The PMMN4170A is the current revision of the legacy PMMN4170 and is TIA4950(UL) intrinsically safe certified for use in hazardous locations. Optimized for the Motorola R5 portable two-way radio.

Frequently Asked Questions
What is Windporting technology and why does it matter?
Windporting is Motorola’s proprietary RSM design that routes the microphone port away from direct wind exposure, eliminating the howling and whining distortion that standard RSMs produce in outdoor or high-wind environments. For field personnel working outdoors — including public safety, utilities, and construction — Windporting significantly improves voice intelligibility when transmitting in windy conditions.
Is the PMMN4170A the same as the PMMN4170?
Yes. The PMMN4170A is the current factory-authorized revision of the legacy PMMN4170 (RM560), offering updated materials and improved performance. Both part numbers refer to the same IMPRES Windporting RSM.
What does the IP67 rating mean for this RSM?
IP67 means the PMMN4170A is completely dustproof (6) and can withstand water immersion up to 1 meter for 30 minutes (7). In practical terms, it continues to function when wet, submerged, or exposed to rain — making it suitable for outdoor operations in all weather conditions.
What is TIA4950(UL) intrinsically safe certification?
TIA4950(UL) is a safety certification indicating the PMMN4170A is approved for use in hazardous locations where flammable gases, vapors, or combustible dust may be present — such as oil and gas facilities, chemical plants, or grain handling operations. This certification is required for accessories used alongside IS-rated radios in those environments.
