Olympus RecMic II RM-4100S Slide Switch & 7 Function Button Professional USB Microphone


Advanced Noise Cancelling Technology

Create clean, accurate verbal notes efficiently with the Olympus RecMic II. This series of desktop dictation microphones combines advanced technologies in an innovative advanced noise cancelling system ideal for noisy environments. The RM-4100S is specifically optimized for use with speech recognition software, capturing natural speaking voices with ease.

Intelligent dual microphones control the directionality to keep the focus on the person dictating and suppress non-voice noise eliminating anything outside the human frequency range. In addition, a triple-layer studio-quality filter blocks traditionally problematic sounds including wind breath noise. The RecMic II microphones retain accurate spoken audio without any distortion while suppressing unwanted noise, making controlling desktop dictation easy.




Accurate & Clear Even in Noisy Environments 

Dual microphone technology creates narrow directionality that focuses on the acoustics in front of the microphone and cancels unwanted noise from the sides and back.


Professional Studio-Quality Filtering 

The triple-layer pop filter uses the same technology found in professional studio recording microphones to block unwanted but difficult-to-eliminate sounds such as breath and wind vibrations.


Intuitive Configuration 

The RecMic II is easily configurable with third-party applications including web applications without having Olympus software running, and can be used as a USB keyboard for easy control simply by changing modes.


Antimicrobial Housing 

The housing and buttons on every RecMic II are made of antimicrobial coating material (ISO 22196). The “tolerance to alcohol” design allows for superior cleanability.
