The new Intelligent Auto Mode provides automatic sensitivity adjustment, and a Low-cut filter removes unnecessary noise from your recordings.
Playback functions – WS-853
Voice Balancer delivers audio quality that is easier to hear – WS-853
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. 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.
