IMPRES Industrial Noise-Canceling Remote Speaker Microphone – IP57 & UL Approved

The Motorola NNTN8382B IMPRES Industrial Noise-Canceling Remote Speaker Microphone is engineered for clear, dependable communication in extremely loud, dirty, and demanding work environments. It allows users to monitor and transmit radio calls from the shoulder or lapel without repeatedly removing the connected radio from a belt or carrying case.

Motorola’s Industrial Noise Cancellation technology uses an innovative dual-microphone design to identify and suppress surrounding noise while isolating the user’s voice. This helps personnel communicate over jackhammers, heavy machinery, engines, manufacturing equipment, and other intense industrial noise.

Integrated IMPRES audio technology allows the microphone and compatible radio to communicate with one another, helping optimize audio performance, suppress ambient noise, and improve voice intelligibility. On-microphone volume controls allow users to adjust incoming audio without reaching for the radio.

The rugged NNTN8382B carries an IP57 rating, protecting it against dust and temporary immersion in water up to one meter for approximately 30 minutes. Its sealed design does not include an external earpiece jack, helping maintain dependable environmental protection in wet and harsh conditions.

The NNTN8382B is approved to the UL/TIA 4950 intrinsic-safety standard for use as part of a properly approved Motorola radio system. It is an excellent choice for manufacturing, utilities, construction, mining, transportation, and other operations requiring clear communication in high-noise or qualifying hazardous locations.
