Everyday Recorder for use in a Wide Variety of Situations.

The WS series established for its clear audio quality and superb operability has been improved. The WS-852 and WS-853 features a new Intelligent Auto Mode, which is perfect for when there is a distance between the speakers and recorder, such as in large meeting rooms. The recorder optimises the recording level regardless of whether the audio source is near or far, making it possible to record audio that is easy to listen to. Simple Mode has been added to the menu for easy, intuitive controls that are perfect for beginners. The new WS series recorders can be used in a wide range of situations, from students to business users.


High Quality Recording

With the ease of use found in all WS series recorders, this model achieves a highly realistic stereo feeling thanks to the two low noise, high sensitivity microphones. The new Intelligent Auto Mode provides automatic sensitivity adjustment, and a Low-cut filter removes unnecessary noise from your recordings.


Usability

The new Simple Mode is perfect for beginners as it displays only necessary information in a large font, and shows only key functions in the menu.


WS-852 Features

Playback Functions

Featuring an array of playback features to accommodate your needs, such as the Voice Filter to clarify and enhance voice within recordings.

By cutting the low and high frequency range, it clarifies and enhances the voice within recordings.

WS-853 Features

Playback Functions

Featuring an array of playback features to accommodate your needs, such as the Voice Balancer for easy listening through equalisation of volume levels.

When voices are recorded at different volume levels due to the distance and physical relationship to the recorder, you can use the Voice Balancer to automatically make smaller voices louder, and ensure that louder voices stay below a given level, providing playback where everyone can be heard clearly.

The noise cancellation function powerfully reduces unwanted ambient noise such as air-conditioner noise or projector fan noise to enable clear playback quality. This function is very effective when playing back meeting recordings.
