Motorola IMPRES Digital Remote Speaker Microphone
Reliable Communications in High-Noise Environments
Engineered for professional deployments, this noise-canceling IP54-rated IMPRES microphone ensures crystal-clear voice transmission even in hazardous and high-noise environments.
The Motorola PMMN4071AL IMPRES Remote Speaker Microphone is a rugged, high-performance audio accessory built specifically for the MOTOTRBO R5, XPR 3000, and XPR 3000e series portable two-way radios. Designed with a larger form factor to allow for easy handling while wearing heavy work gloves, this microphone utilizes Motorola's exclusive IMPRES audio technology to optimize speaker output and provide superior noise suppression. The PMMN4071AL features an IP54 rating to withstand dust and splashing water, making it a reliable solution for construction, manufacturing, and industrial operations.
For operators working in specialized or dangerous conditions, this microphone is UL-approved and TIA4950 certified intrinsically safe, allowing it to be used in potentially explosive environments when paired with a matching intrinsically safe radio. Additionally, it features a built-in 3.5mm non-threaded audio jack on the side of the microphone head, allowing users to plug in a listen-only earpiece for discreet, private communication.

Frequently Asked Questions
Is the Motorola PMMN4071AL waterproof?
The PMMN4071AL has an IP54 rating, meaning it is protected against dust ingress and splashing water. While it can withstand rain and standard work environments, it is not fully waterproof and should not be submerged in water.
What does the 3.5mm audio jack do on this microphone?
The built-in 3.5mm unthreaded audio jack allows you to plug in a compatible receive-only earpiece. When an earpiece is connected, the incoming radio transmissions are routed directly to your ear instead of broadcasting out loud from the speaker microphone.
Can I use this microphone on a non-intrinsically safe radio?
Yes. While the PMMN4071AL is UL-certified as intrinsically safe, it is perfectly fine to use on standard, non-UL Motorola R5, XPR 3000, and XPR 3000e series radios. However, the entire radio system is only considered intrinsically safe if both the radio and the attached microphone carry the UL certification.
