SpeechLine Digital Wireless: System Information

►
SpeechLine Digital Wireless is the first digital wireless micro-
phone system designed specifically for the spoken word.
SpeechLine Digital Wireless is a future-proof solution that’s
easy to set up, use and manage and that lets the presenter
concentrate on their words, not on the technology.
SpeechLine Digital Wireless comprises mobile transmitters
(handheld or bodypack) tailored for speech applications,
speech optimized condenser microphones (a microphone cap-
sule for the handheld transmitter, a clip-on or headset micro-
phone for the bodypack transmitter) and a rack receiver. The
transmitters are powered by rechargeable lithium-ion accu-
packs with a battery life of more than 15 hours. The accupacks
can be recharged with the charger or via USB. SpeechLine
Digital Wireless has an automatic frequency management fea-
ture that automatically searches for free frequencies on site,
thus eliminating the need for time-consuming frequency plan-
ning in advance. In addition, the automatic interference man-
agement function always ensures a stable wireless
connection, and thus provides maximum transmission reliabil-
ity. The automatic microphone sensitivity adjustment makes
the setup even more convenient since there is no need for
manual level adjustment. What is more, network integration
enables SpeechLine Digital Wireless to be remote controlled
and monitored using a media control system (e.g. AMX, Cre-
stron) or the browser-based Sennheiser Control Cockpit soft-
ware.

Focus on the spoken word
►
The spoken word is and remains the most personal and pow-
erful instrument 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 im-
portant that none of the content is lost when audio devices
such as wireless microphones and the associated receivers
are used.

SpeechLine Digital Wireless – the profession-
al solution for speakers, lecturers and pre-
senters
►
The best wireless microphones and receivers are those which
the speaker does not need to think about because they are
ready for immediate use, automatically establish the most re-
liable radio link and provide maximum transmission reliability
in every application and all day long. The microphones and the
receiver of the SpeechLine Digital Wireless series are de-
signed for optimum speech intelligibility, offer maximum se-
curity thanks to encrypted transmission, and provide for
seamless integration into an existing conference system, a
media control system or a telephone system. The unobtrusive
design blends in perfectly with your conference or training
room, the auditorium or the presentation stage.

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, meet-
ings 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 es-
sential that every word can be understood. If active speakers
walk around during the presentation or turn away from the au-
dience, they are completely intelligible at all times thanks to
SpeechLine Digital Wireless.

Meetings
►
Good speech intelligibility and easy handling of the micro-
phone system are important requirements for professional
meetings. The larger the conference or training room, the
more helpful is an audio system which enhances speech intel-
ligibility. In large conference rooms in particular, a speaker
seated at one end is difficult to understand at the other end.
When the speaker turns in different directions, for example in
order to address individual participants, he is difficult to un-
derstand in the other direction in each case. SpeechLine Digi-
tal Wireless does not restrict the freedom of movement of
active speakers.

Teleconferences
►
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 transmis-
sion for all participants in the room, the SpeechLine Digital
Wireless system can easily be connected to an existing tele-
conference unit such as the Sennheiser TeamConnect system.
This processes the audio signals and establishes the connec-
tion to the remote participants.

What are the features of SpeechLine Digital
Wireless?

Automatic frequency management
SpeechLine Digital Wireless finds free transmission frequen-
cies 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
– and that’s all.
The transmitter and the receiver are pre-paired at the factory
and immediately work together. If necessary, this pairing can
be changed at any time, for example in order to switch from a
clip-on microphone to a handheld transmitter. It is also possi-
ble to use several transmitters, such as when each lecturer at
a university uses their own microphone.
Automatic microphone sensitivity adjustment
It is not necessary to manually adapt the input sensitivity to
the microphone used, and the audio level is automatically ad-
justed for different speakers. In addition, different sound pro-
files are defined for male and female voices. In this way, the
high-quality microphones of the SpeechLine Digital Wireless
series can unleash their full potential without distortion.
Automatic level management
The level of the audio signal is automatically optimally adjust-
ed so that the speaker's voice can be heard loud and clear. If
necessary, the receiver's output level can be manually adapt-
ed to the input of the mixing console or amplifier.
Automatic interference management
The system immediately reacts to interfering signals such as
those coming from DECT telephones by automatically chang-
ing the frequency. This prevents interference and audio drop-
outs and ensures an uninterrupted connection. The automatic
frequency change is not noticed by the user of the microphone
or by the audience. If several radio links are active for different
speakers at the same time, the respective frequencies are au-
tomatically selected so that they cannot interfere with each
other. The frequencies are immediately adapted to newly add-
ed radio links without interfering with the ongoing transmis-
sion or even interrupting it.
