IMPRES Small RSM (PMMN4550)

PMMN4550

This RSM features IMPRES technology, providing superior audio by suppressing ambient noise, improving voice intelligibility and amplifying quiet transmissions.

Communicate clearly in difficult weather with this Remote Speaker Microphone featuring Windporting technology. Windporting eliminates the whining and howling sounds of wind blowing across your remote speaker microphone while preventing water from clogging the microphone, resulting in clearer transmissions.

Built to survive, this RSM is approved to IP55 meaning it can withstand jets of water and dust won't affect the operation no matter what.

Summon help precisely when it is needed with this RSM featuring an emergency alarm button.

The 3.5mm audio jack supports a discreet, receive-only earpiece.
