Create clean, accurate verbal records efficiently with the Olympus RecMic II. This series of desktop dictation microphones combines advanced technologies in an innovative noise canceling system ideal for noisy environments.

The RM-4000P offers more configurable function buttons than any other microphone on the market, ensuring complex commands are simple and workflow within your EHR/PACS is efficient.

Dual microphones narrow the directionality to keep the focus on the person dictating, intelligent noise suppression cancels non-voice noise eliminating anything outside the human frequency range, and a triple-layer studio-quality filter blocks traditionally problematic sounds including breath noise. The RecMic II microphones retain accurate spoken audio without any distortion while suppressing unwanted noise, making desktop dictation easy.



Accurate & Clear Speech Recognition in a Noisy Environment

Dual microphone technology creates narrow directionality that focuses on the acoustics in front of the microphone and suppresses 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.

Antimicrobial Body

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

Work Smarter and Faster

Designed especially for heavy users with complicated applications, the RM-4000P eliminates the need for a mouse. Customize the 7 function buttons to automate frequently used features or create shortcuts for common commands.

    I've been using the Olympus RecMic II for a awhile now, and I have to say that it works really well. The noise cancelation is great, and the audio is crisp and clear. It's also incredibly easy to use; you can quickly switch between dictations and make changes to the settings a few times a day. This is a great desk-top microphone for the healthcare industry.
