The low-noise directional stereo microphones with a 90° layout deliver a superb stereo feeling – enabling you to feel even the smallest details of the meeting. Regardless of where the person speaking is located or the direction of speech, you can clearly capture the information.
To make listening to your recordings more comfortable, Intelligent Auto Mode automatically adjusts the recording level to match the volume of the sound source. When a speaker is talking very loudly, the recorder reduces the input level, and for soft voices the recorder increases the input level – to always provide an even level of volume.
With two different display modes, you can use your voice recorder even if you are a beginner. Simple Mode displays only essential information in large font and limits the menu options to frequently-used functions. For advanced users, full functionality of menu options is available in Normal Mode.
Save data easily and conveniently with the built-in USB connector. Simply slot it into your PC or Mac to transfer voice recordings from the device to an external hard disk drive. You can also use it like a USB stick to share documents. For the WS-853, the USB connector has an additional internal battery charge function for further peace of mind.
