Page 11: Speechline Digital Wireless - The Professional Solution For Speakers, Lecturers And Presenters
The microphones and the receiver of the SpeechLine Digital Wireless series are designed for optimum speech intelligibility, offer maximum security thanks to encrypted transmission, and provide for seamless integration into an existing conference system, a media control system or a telephone system.
Page 12: Typical Applications
| 2 - System information 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 auditorium or a large conference room, it is essential that every word can be understood.
Page 13 When the speaker turns in different directions, for example in order to address individual participants, he is difﬁcult to understand in the other direction in each case. SpeechLine Digital Wireless does not restrict the freedom of movement of active speakers.
Page 14 In modern ofﬁce life, teleconferences are becoming more and more important for the cooperation of international teams. As a telephone alone can only offer inadequate speech transmission for all participants in the room, the SpeechLine Digital Wireless system can easily be connected to an existing teleconference unit such as the Sennheiser TeamConnect system.
Page 15: What Are The Features Of Speechline Digital Wireless
What are the features of SpeechLine Digital Wireless? Automatic frequency management SpeechLine Digital Wireless ﬁnds free transmission frequencies reliably and fully automatically. Manual intervention is not necessary in the search for a free frequency. This means that your wireless microphone and the receiver are ready for use within an extremely short time: connect them, switch them on –...
Page 16 In addition, the frequencies in this band can be used without a license. With SpeechLine Digital Wireless, you don't have to fear changes to the frequency band used which could possibly mean having to buy new audio equipment. The acquisition of a SpeechLine Digital Wireless system is a future-proof investment.
