  • Page 3 SpeechLine Digital Wireless: System Information SpeechLine Digital Wireless comprises mobile transmitters (handheld or bodypack) tailored for speech applications, speech optimized condenser microphones (a microphone capsule for the handheld transmitter, a clip-on or headset microphone for the bodypack transmitter) and a rack receiver. The transmitters are powered by rechargeable lithium-ion accupacks with a battery life of more than 15 hours.
  • Page 4 Focus on the spoken word Focus on the spoken word ► The spoken word is and remains the most personal and powerful instru- ment of communication we know. It allows us to convince people, to impart knowledge and to voice opinions, thoughts and views as well as emotions. That is why it is so important that none of the content is lost when audio devices such as wireless microphones and the associated receivers are used.
  • Page 5 The micro- phones and the receiver of the SpeechLine Digital Wireless series are de- signed for optimum speech intelligibility, offer maximum security thanks to encrypted transmission, and provide for seamless integration into an exist- ing conference system, a media control system or a telephone system.

  • Page 6: Typical Applications

    Focus on the spoken word Typical applications Excellent speech intelligibility, easy handling and convenient control are to the fore at all times, regardless of whether SpeechLine Digital Wireless is used in presentations, meetings or telephone conferences. Presentations ► In the case of a presentation held before a large audience, such as in an au- ditorium or a large conference room, it is essential that every word can be understood.
  • Page 7 Focus on the spoken word Meetings ► Good speech intelligibility and easy handling of the microphone system are important requirements for professional meetings. The larger the confer- ence or training room, the more helpful is an audio system which enhances speech intelligibility.
