SpeechLine Digital Wireless: System Information

SpeechLine Digital Wireless:

System Information

►

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.

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 fre-

quency management feature that automatically searches for free frequen-

cies 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 Senn-

heiser Control Cockpit software.

ital Wireless series, see „The Products of the SpeechLine Digital Wireless

Series“.

Wireless series under „SpeechLine Digital Wireless: Instruction manual“.

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.

Focus on the spoken word

10

SpeechLine Digital Wireless – the professional solu-

tion 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, au-

tomatically establish the most reliable radio link and provide maximum

transmission reliability in every application and all day long. 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. The

unobtrusive design blends in perfectly with your conference or training

room, the auditorium or the presentation stage.

Focus on the spoken word

11

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. 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.

Focus on the spoken word

12

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. 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 indi-

vidual 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.

Focus on the spoken word

13

Teleconferences

►

In modern office life, teleconferences are becoming more and more import-

ant 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 ex-

isting teleconference unit such as the Sennheiser TeamConnect system.

This processes the audio signals and establishes the connection to the re-

mote participants.

Focus on the spoken word

What are the features of SpeechLine Digital Wire-

less?

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 re-

ceiver 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 immedi-

ately 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 micro-

phone used, and the audio level is automatically adjusted for different

speakers. In addition, different sound profiles are defined for male and fe-

male 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 pre-

vents interference and audio dropouts and ensures an uninterrupted con-

nection. 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.

Focus on the spoken word

15

Future-proof, license-free audio transmission

SpeechLine Digital Wireless operates in the future-proof 1.9 GHz frequen-

cy band. Transmission in this band is not affected by regulatory changes of

the digital dividend or by the auctioning of frequencies. In addition, the fre-

quencies in this band can be used without a license. With SpeechLine Dig-

ital Wireless, you don't have to fear changes to the frequency band used

which could possibly mean having to buy new audio equipment. The acqui-

sition of a SpeechLine Digital Wireless system is a future-proof invest-

ment.

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,

the Adaptive Power Mode ensures extremely easy startup and a reliable

maximum range. The Multi-Room Mode allows you to adjust the transmis-

sion power to allow for a considerably larger number of links. These adjust-

ment 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 import-

ant 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, con-

trol 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 adjust-

ments for one or multiple devices at the same time very easy. The room

overview connects the locations of all components to their respective sta-

tus information, so the user always knows the location and status of a spe-

cific device. The Sennheiser Control Cockpit is accessible everywhere in

the intranet via a web browser across all platforms. As a result, the soft-

ware allows you to manage even huge setups with hundreds of devices

with minimal effort.

The SL Rack Receiver DW receiver

►

The 9.5" rack receiver (SL Rack Receiver DW) is the core of the SpeechLine

Digital Wireless system. Thanks to the bi-directional communication be-

tween the rack receiver and the transmitter, all transmitter settings can be

adjusted on the receiver. The receiver's automatic frequency management

eliminates the need for manual frequency setting and the automatic inter-

ference management ensures maximum transmission reliability. The user-

friendly pairing function ensures a reliable connection between the trans-

mitter and the receiver. Network integration enables the receiver to be re-

mote controlled and monitored using a media control system (e.g. AMX,

Crestron) or the Sennheiser Control Cockpit software. The antennae can

either be mounted to the rear of the receiver or to the front of a rack. An-

tenna cables of different lengths also allow mounting the antennae re-

motely from the receiver. The antenna cables are available as accessories.

17

The handheld transmitter

►

The handheld transmitter (SL Handheld DW) is ideal when several persons

are speaking at the same time, such as in interviews or when queries come

from the audience. You can replace the microphone capsule if necessary.

The handheld transmitter is supplied with the high-quality MME 865-1 mi-

crophone capsule. The MME 865-1 has excellent presence and high feed-

back rejection and is specially designed for speech applications.

Thanks to its easy handling, the handheld transmitter is available to the

speaker for immediate use, and no further instruction is necessary. The

functions of the handheld transmitter have been reduced to a minimum to

allow stress-free speaking during the presentation and to ensure that the

speaker is not distracted by unnecessary operating options.

The Products of the SpeechLine Digital Wireless Series

18

The bodypack transmitter

►

The compact, robust bodypack transmitter (SL Bodypack DW) is compati-

ble with all Sennheiser headset and clip-on microphones (e.g. SL Headmic

1 or MKE 1). Thanks to the bi-directional communication between the trans-

mitter and the receiver, no settings need to be adjusted on the transmitter.

The transmitter's LC display indicates the link name, the battery status and

the reception quality. The functions of the bodypack transmitter have been

reduced to a minimum to allow stress-free speaking during the presenta-

tion and to ensure that the speaker is not distracted by unnecessary oper-

ating options. With the easy-to-access mute switch, the transmitter can be

muted if necessary.
