Motorola’s Remote Speaker Microphones (RSMs) are a vital two-way radio accessory solution for users who need to talk and listen without removing the radio from their belt or carry case. A basic RSM combines a loudspeaker, microphone and Push-To-Talk button (PTT) in a compact device with a clip to hold it in place and a cable to connect to the radio accessory connector.
Some RSMs also offers enhanced functionality: dedicated emergency and programmable buttons to allow quick access to frequently used functions; volume controls to adjust received audio levels, or an audio jack that allows an earpiece to be connected, ensuring discreet communication that can’t be overheard and won’t disturb others.
The Right "Fit And Feel" For All Your Needs
In addition to standard RSM features, Motorola Solutions has also developed exclusive capabilities for Motorola’s RSMs – they offer a range of models so users can select the best fit and feel for their specific needs. Windporting, Noise Canceling, IMPRES™, and INC help ensure optimal performance even in noisy or windy environments.

Windporting Remote Speaker Microphones (RSM)
The Windporting feature on select RSMs/PSMs is specifically designed for windy outdoor environments. If you’re directing traffic or moving crowds after an outdoor concert, Windporting dramatically reduces the noise caused by howling winds and harsh weather. And it prevents water from clogging the microphone and distorting your transmission.
In a domed stadium or an open-air event, noise-canceling acoustics on select RSM models negate background noise so your voice comes through loud and clear anytime you speak into the microphone. IP57 Submersible model tested at 1 meter for 30 minutes.
Industrial Noise Cancellation - INC (Motorola Exclusive)
Some areas, like plant rooms, sports stadiums, shunting yards or factory floors can experience extreme noise where standard noise Canceling RSM’s may struggle to eliminate the high levels of background noise. A new class of RSM was introduced in June 2013; it incorporated Industrial Noise Cancellation to provide superior performance in the most difficult of situations.
The RSM utilizes microphones purposely designed to operate at levels that would saturate standard microphones and include two mics to help steer your voice (like a beam of light from a torch) to eliminate ambient noise. Additionally, the INC RSM uses Digital Signaling Processing to extract noise in the speech the speech for transmission. So, unlike standard noise Canceling, low frequency generator noise, angle grinders or even sirens from emergency services are all cancelled out.
