Motorola PMMN4131B IMPRES RM730 Small Remote Speaker Microphone (IP68)

Motorola PMMN4131B

IMPRES RM730 Small Remote Speaker Microphone (IP68)

Professional Audio Performance in a Compact Form

The Motorola PMMN4131B (RM730) is a high-performance, compact remote speaker microphone (RSM) designed for mission-critical clarity. This IMPRES-enabled accessory is engineered to withstand the most punishing environments, featuring an IP68 submersibility rating that allows it to survive in 2 meters of water for up to 4 hours. As the updated version of the PMMN4131 series, it offers a sleeker, low-profile design that stays close to the body without compromising on audio power.

Equipped with a 99 Phon loud speaker, the RM730 delivers industry-leading volume to cut through heavy machinery and environmental noise. The integrated windporting technology ensures that your voice remains intelligible by canceling out wind noise and preventing water from clogging the microphone grill during rain or storms.

Key Features

IMPRES Technology: Automatically optimizes audio levels and suppresses background noise for consistent, high-quality transmissions.
Windporting Microphone: Eliminates the roaring sound of wind and sheds water quickly for clear communication in outdoor weather.
IP68 Submersibility: Certified dust-proof and waterproof, designed for use in extreme field conditions and heavy rain.
99 Phon Speaker: Provides exceptionally loud and crisp audio, ensuring incoming calls are heard in high-decibel environments.
Orange Emergency Button: Features a large, tactile emergency key for rapid distress signaling.
3.5mm Audio Jack: Supports the connection of optional secondary earpieces for discreet, private listening.
360° Swivel Clip: A low-profile, rotating clip ensures the microphone stays securely positioned on any uniform or tactical vest.
