SpeechLine Digital Wireless is the first digital wireless microphone 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.
7
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. The accupacks can be recharged with
the charger or via USB. SpeechLine Digital Wireless has an automatic frequency management feature that automatically searches for free frequencies on site, thus eliminating the need for time-consuming frequency
planning in advance. In addition, the automatic interference management
function always ensures a stable wireless connection, and thus provides
maximum transmission reliability. 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, Crestron) or the browser-based Sennheiser Control Cockpit software.

Focus on the spoken word
►
Focus on the spoken word
The spoken word is and remains the most personal and powerful 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 important that none of the content is lost when audio
devices such as wireless microphones and the associated receivers are
used.
9
Focus on the spoken word
SpeechLine Digital Wireless – the professional solution for speakers, lecturers and presenters
►
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 reliable 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 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. The
unobtrusive design blends in perfectly with your conference or training
room, the auditorium or the presentation stage.
10
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 auditorium or a large conference room, it is essential that every word can be
understood. If active speakers walk around during the presentation or turn
away from the audience, they are completely intelligible at all times thanks
to SpeechLine Digital Wireless.
11
Meetings
►
Focus on the spoken word
Good speech intelligibility and easy handling of the microphone system are
important requirements for professional meetings. The larger the conference or training room, the more helpful is an audio system which enhances
speech intelligibility. 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 understand in the other direction in
each case. SpeechLine Digital Wireless does not restrict the freedom of
movement of active speakers.
12
Teleconferences
►
Focus on the spoken word
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.
This processes the audio signals and establishes the connection to the remote participants.
13
Focus on the spoken word
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 – 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 possible 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 adjusted for different
speakers. In addition, different sound profiles 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 adjusted so that the
speaker's voice can be heard loud and clear. If necessary, the receiver's
output level can be manually adapted 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 changing the frequency. This prevents interference and audio dropouts 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 automatically
selected so that they cannot interfere with each other. The frequencies are
immediately adapted to newly added radio links without interfering with
the ongoing transmission or even interrupting it.
Future-proof, license-free audio transmission
SpeechLine Digital Wireless operates in the future-proof 1.9 GHz frequency band. Transmission in this band is not affected by regulatory changes of
the digital dividend or by the auctioning of frequencies. 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.
To allow optimum use of the 1.9 GHz frequency band, SpeechLine Digital
Wireless offers two operating modes: For up to 20* links used in parallel,
14
Focus on the spoken word
the Adaptive Power Mode ensures extremely easy startup and a reliable
maximum range. The Multi-Room Mode allows you to adjust the transmission power to allow for a considerably larger number of links. These adjustment options make SpeechLine Digital Wireless the optimum solution for
a great variety of projects with widely differing installation sizes at the
same location.
* depending on the locally approved variant
Tap-proof audio transmission
The encrypted, tap-proof transmission of information is especially important in the corporate environment. This is why we decided to use 265-bit
AES encryption when developing the SpeechLine Digital Wireless series.
Here the security of wireless transmission is ensured by the generation of
a new key each time a new connection is made between transmitter and
receiver. At every meeting and every conference, this guarantees that only
the receiver paired with the transmitter is able to decode the audio signal.
Encryption cannot be deactivated – making SpeechLine Digital Wireless
secure at all times.
Extremely long battery life
It is not necessary to replace or recharge the accupack during operation.
The battery life is about 15 hours – enough for even a very long conference
day. Intelligent energy management using adaptive transmission power
maximizes the battery life.
To charge the accupacks, it is not necessary to remove them from the
transmitters. They can be recharged using the optional CHG 2 charger for
handheld and pocket transmitters or directly via the supplied USB charging
cable.
Easy control using the Sennheiser Control Cockpit software
Sennheiser Control Cockpit is the central software for easy handling, control and maintenance of the entire SpeechLine Digital Wireless system.
The easy-to-use Sennheiser Control Cockpit software provides a global
overview of all network enabled SpeechLine Digital Wireless devices at all
times. It shows all status information at a glance and makes setting adjustments for one or multiple devices at the same time very easy. The room
overview connects the locations of all components to their respective status information, so the user always knows the location and status of a specific device. The Sennheiser Control Cockpit is accessible everywhere in
the intranet via a web browser across all platforms. As a result, the software allows you to manage even huge setups with hundreds of devices
with minimal effort.
