{tab Overview}

Fully featured recorder for high performance and ease ofuse.

The WS series established for its clear audio quality andsuperb 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 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 thanksto 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.

Superb stereo feeling with True Stereo Microphones

Two low-noise directional microphones positioned at a 90° layout enable you to create high quality recordings with a realistic stereo feeling.

This feature ensures that you capture the sense of direction and distance of the speakers in the recording which is useful for meetings, lectures or training presentations.

 

Automatic sensitivity adjustment with Intelligent Auto Mode

The new Intelligent Auto Mode function automatically adjusts the microphone sensitivity according to the input level.

For example, when you record the voice of a person far away in a large meeting room, the input level tends to be lower. In this case, the recorder automatically raises the sensitivity of the microphone making them easier to hear.

Alternatively, when you record in a smaller meeting room with only a few people, the sensitivity is automatically lowered, so that the voice of the speakers close by do not sound too loud.

In this way, the function automatically keeps track of the input level and simultaneously adjusts the recording level so that it always records in the best quality.

This ensures that the recording remains consistent by nothaving a speaker’s voice too quiet or too loud.

To set this function, simply select "Auto" as the recording level from the menu.

• *If you select "Conference" for the recording scene while in Simple Mode, Intelligent Auto Mode is activated.

Low-cut filter eliminates extraneous noise

During recording, the low-cut filter is used to cut the sound at frequencies of 300 Hz and lower during the recording process.

Typical examples of these lower frequencies include air conditioner noise, projector fan noise, and even wind noise while outside.

By cutting the lower frequency during recording your audio is natural sounding and free of background noise and distortion during playback.

 

Playback functions

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

Voice Balancer delivers audio quality that is easier to hear

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 smallervoices louder, and ensure that louder voices stay below a given level, providing playback where everyone can be heard clearly.

This comes in handy when recording sound sources from multiple positions, such as in a large meeting or conference.

Since the voice filter operates simultaneously, the prominent noise produced when amplifying small sounds is also reduced.

By eliminating the lower and higher frequencies during playback, recorded voice is even further enhanced.

This enables much clearer playback than the functions offered by our competitors.

The File Divide function makes it easier to handle longer recordings

Recordings of long meetings with multiple topics or audiofiles that are too big to send via email can be divided on the recorder without having to use a computer.

This makes it easier to manage files according to the content, or divide files into a smaller size to send via email.

The built-in stand prevents noise during desktop recording

The recorder is equipped with a convenient stand on the rear of the body.

This feature reduces unwanted noise that can be picked upfrom the surface when the recorder is placed directly on a table top, and can be folded neatly into the body when not in use.

Long battery life you can rely on when out and about

By developing low power consumption circuits, battery life of the recorder has been significantly increased.

Users can rely on the recorder even when using it for long periods of time.

The supplied AAA battery is rechargeable and can be charged via USB without being removed from the recorder, making it very convenient for everyday use.

The recorder can also run on general purpose AAA batteries, so you never have to worry about running out of power when out and about.
