Olympus WS-853

RM 489.00


Fully featured recorder for high performance and ease of use.

The WS series established for its clear audio quality and superb operability has been improved. The new 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 optimizes 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.

Playback functions

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

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.
