SpeechLine Digital Wireless: System Information

2

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 thats 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.

Focus on the spoken word

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 thats 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.

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 auction- ing 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 equip- ment. The acquisition of a SpeechLine Digital Wireless system is a future-proof investment.

To allow optimum use of the 1.9 GHz frequency band, Speech- Line 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 transmission pow- er to allow for a considerably larger number of links. These ad- justment 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 espe- cially 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 wire- less 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 guaran- tees 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 op- tional CHG 2 charger for handheld and pocket transmitters or directly via the supplied USB charging cable.

Number and size of the rooms

Determine the number of rooms needed for the installation.

Determine how each individual room is to be equipped and used.

Determine the audio equipment for each room, i.e. the de- sired number of SpeechLine Digital Wireless links.

Check if there are other devices (e.g. DECT devices) using the 1.9 GHz frequency band.

Double-check that the number of 1.9 GHz devices used on- site does not exceed the available spectrum (see Shared use of the 1.9 GHZ frequency band).

Planning

35

Shared use of the 1.9 GHZ frequency band When SpeechLine Digital Wireless is used in combination with other devices using the 1.9 GHz frequency band (e.g. Sennhe- iser TeamConnect Wireless or DECT telephones), the maxi- mum number of SpeechLine Digital Wireless links depends on the number of other devices used.

Analysis of the environmental conditions When planning the installation of a SpeechLine Digital Wire- less system, you should also carefully analyze the environ- mental conditions. Are there any other 1.9 GHz devices (e.g. DECT telephones or DECT access points) already installed?

Observe the following aspects when planning an in- stallation

Identify the locations of DECT access points (e.g. for DECT telephone systems). Also observe the information provided under Shared use of the 1.9 GHZ frequency band.

Determine the type of installation, i.e. where and how the microphone receivers are to be installed.

Determine whether the antennae are to be mounted re- motely from the receivers. When remote mounting the an- tennae, also take into account possible losses due to long cable runs. Also see Recommendations on antenna mounting.

When installing remote antennae, observe a minimum dis- tance of 3 m to the next DECT access point.

To make network control very simple, we recommend using a network switch to connect the receivers in the network.

Recommendations on antenna mounting

38

Recommendations on antenna mount- ing There are different factors to consider when mounting anten- nas. This chapter provides instructions and recommendations that you should follow when mounting antennae.

Antenna setup and planning for SpeechLine Digital Wireless When planning the installation of SpeechLine Digital Wireless devices for each room, observe the following guidelines.

Mount all SpeechLine Digital Wireless receivers together in one rack.

Make sure to have a direct line of sight between the trans- mitters and the receiving antennas.

Depending on the room characteristics there are several options how to install the receiving antennas. We recom- mend the following options in this order: Option 1: remotely mounted using the AWM 2 for one re-

ceiver or the AWM 4 for two receivers. >> Option 1: Con- necting the AWM 2 or AWM 4 antenna wall mount directly to the receiver(s)

Option 2: remotely mounted using the AWM 2 or AWM 4 and multiple receivers combined using an antenna split- ter (passive splitters SL PASC 2 or SL PASC 4). >> Option 2: Combining multiple links to one AWM 2/AWM 4

Option 3: mounted in a rack (front). >> Option 3: Rack mounting - front

Option 4: mounted in a rack (rear). >> Option 4: Rack mounting - rear

When mounting antennas remotely, observe the minimum distance to possibly existing DECT access points and also take into account the cable lengths.

Always switch all receivers on and off with a common pow- er supply (e.g. a multi-outlet power strip with a central on/ off switch) in order to achieve the best performance of a system.

You can find detailed information about the four an- tenna mounting options under Antenna mounting op- tions.

Recommendations on antenna mounting

39

Antenna mounting options There are different options for remote mounting the antennas. We recommend the following four options in the specified or- der.

>> Option 1: Connecting the AWM 2 or AWM 4 antenna wall mount directly to the receiver(s)

>> Option 2: Combining multiple links to one AWM 2/AWM 4

>> Option 3: Rack mounting - front

>> Option 4: Rack mounting - rear

Recommendations on antenna mounting

40

Option 1: Connecting the AWM 2 or AWM 4 antenna wall mount directly to the receiver(s) You can connect one receiver directly to one AWM 2 antenna wall mount or you can connect two receivers directly to one AWM 4 antenna wall mount.

For the AWM 2, you can use Sennheiser extension cables CL 5/10/20.

For the AWM 4, you can use Sennheiser extension cables CL 1/5/10/20 PP.

Observe the following information when using extension ca- bles:

Signal loss due to extension cables

In this scenario, using extension cables for remote antenna mounting results in a loss of transmission power, depending on the cable length.

You can compensate this signal loss by configuring the trans- mission power of the receiver accordingly.

Observe the following minimum transmission power set-

Remote antenna distances and line of sight

If you are using multiple antenna wall mounts (AWM 2/AWM 4) in one room or if individual installation and mounting of the antennas is desired, please observe the following aspects:

Position all antennas as close as possible to each other. Make sure that the distances between all antennas are all

equal and the same as on the back of the receiver or on the AWM 2 antenna wall mount.

Option 2: Combining multiple links to one AWM 2/AWM 4 With this variant, you can use passive antenna splitters (SL PASC 2 or SL PASC 4) together with the AWM 2 or AWM 4 to combine the antenna signals from multiple receivers. This reduces the number of antenna cables required to a minimum.

Combining up to 2 links using the AWM 2 and the SL PASC 2

The following illustration shows an example of how to com- bine up to 2 links with one AWM 2 antenna wall mount. This re- duces the number of antenna cables required from 4 to 2.

Please observe the information below on the length of the extension cables (Signal loss due to extension cables and antenna splitters).

minating resistor (50 ) to minimize interfering signals and maximize transmission power.

Signal loss due to extension cables and antenna splitters

In this scenario, the use of extension cables and antenna split- ters with a remotely mounted antenna may result in loss of transmission power, depending on the cable length.

You can compensate this signal loss by configuring the trans- mission power of the receiver accordingly. Observe the follow- ing minimum transmission power settings (SL Rack Receiver DW: System Settings menu -> RF Power) for the respective cable lengths. The antenna splitter causes about as much sig- nal loss as a cable length of 15 m. These losses must be includ- ed in the calculation of the transmission power level.

We recommend the following cable lengths in combination with the antenna splitter:

Receiver to splitter: 1 m -> splitter to AWM 2/4: 1 m Receiver to splitter: 1 m -> splitter to AWM 2/4: 5 m Receiver to splitter: 1 m -> splitter to AWM 2/4: 10 m Receiver to splitter: 5 m -> splitter to AWM 2/4: 1 m Receiver to splitter: 5 m -> splitter to AWM 2/4: 5 m Receiver to splitter: 10 m -> splitter to AWM 2/4: 1 m

Cables longer than 10 m are not recommended for this variant.

This results in the following transmission power levels to be set in the menu of the receiver or simultaneously for all receiv- ers in the Sennheiser Control Cockpit software:

5 m cable length plus splitter -> at least level 2 10 m cable length plus splitter -> at least level 3

Direct line of sight

If possible, position the antennas so that there is a direct line of sight (without obstacles) between the transmitters and the antennas.

Recommendations on antenna mounting

47

Option 3: Rack mounting - front If you wish to install the antennae together with the receivers in a rack, we recommend mounting the antennae on the front side of the rack using the GA 4 mounting kit.

Always leave 1 U of space between receivers and antennae. Position the antennas at an angle of about 45.

Recommendations on antenna mounting

48

Option 4: Rack mounting - rear If you cannot mount the antennas at the front of the rack (op- tion 3), you can also mount them at the rear of the receiver in the rack. When mounting, observe the following information.

Position the antennas so that they point at a 180-degree an- gle away from the receiver.

Run all cables close to the receivers to prevent the cables from interfering with the antenna reception. Use the cable grip.

For best system performance, make sure that the antennas are not covered or shielded by blocking obstacles such as cables, metal plates, or cases.

In this case, and if possible, make sure that there is a direct line of sight between the transmitters and the receivers for best possible RF performance.

Further important information on antenna us- age

Reflecting surfaces

Electrically conducting surfaces (e.g. ceilings with metal con- structions) can reflect the RF signal.

The signal is reflected by the electrically conducting surface. At worst, the blue signal and the red reflected signal are out of phase when they reach the receiver so that the two signals cancel each other out.

If you have electrically conducting surfaces in a room, make sure to position the receiver or the antenna wall mounts so that such reflection effects are avoided. If you have a reflecting ceiling, this can be achieved by po- sitioning the antennae closer to the ceiling.

Blocking effects from other transmitters

As with all wireless microphone systems, suboptimal position- ing of transmitters can lead to blocking effects. To avoid this, please follow these recommendations:

Position DECT telephone or DECT access points at least 7 m from the antennae.

Position other wireless devices such as mobile phones at least 1 to 2 m from the antennae.

When transmitters are currently in use, you must not posi-

tion any other transmitters in the blocking area. If you must position them there, switch them off.

Rule of thumb for distance from the blocking area:

Multi-room mode SpeechLine Digital Wireless, by taking into account the instal- lation size as well as country-specific regulations, allows to optimally use the 1.9 GHz frequency band.

SpeechLine Digital Wireless offers two operating modes for different types of installation: the automatic mode with adap- tive transmission power for single-room installations (Adap- tive Power Mode) and the manual mode for multi-room installations, which is known as Multi-Room Mode.

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 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 (see Country- Specific Variants).

When installing and starting up SpeechLine Digital Wireless systems in projects of different sizes, observe the following steps.

SL Rack Receiver DW The 9.5" rack receiver (SL Rack Receiver DW) is the core of the SpeechLine Digital Wireless system. Thanks to the bi-direc- tional communication between the rack receiver and the transmitter, all transmitter settings can be adjusted on the re- ceiver. The receiver's automatic frequency management elim- inates the need for manual frequency setting and the automatic interference management guarantees maximum transmission reliability. The user-friendly pairing function en- sures a reliable connection between transmitter and receiver. Network integration enables the receiver to be remotely con- trolled and monitored using a media control system (e.g. AMX, Crestron) or the Sennheiser Control Cockpit software. The an- tennae can either be mounted to the rear of the receiver or to the front of a rack. Antenna cables of different lengths also al- low mounting the antennae remotely from the receiver. The antenna cables are available as accessories.

Integrating the receiver into a network with DHCP

The receiver obtains the IP address from the DHCP server. You can see this address in the Network Settings menu on the re- ceiver (see Using the operating menu of the receiver).

To add the receiver in the Sennheiser Control Cockpit: Use the Add Device function in the Sennheiser Control

Cockpit and enter the IP address you saw in the settings menu.

Or:

Activate the mDNS function in the receivers Network Set- tings menu (factory setting: deactivated).

Restart the receiver. Once restarted, the receiver is automatically detected in the Sennheiser Control Cockpit.

mDNS = multicast Domain Name System: resolves host names to IP addresses within small networks that do not include a local name server. Used for auto- matic device discovery.

Integrating the receiver into a network without DHCP using Auto IP

If there is no DHCP server in the network and you are working with automatically generated IP addresses, please observe the following information.

Set the Mode to Automatic in the receivers Network Set- tings menu.

Ensure that the host PC on which the Sennheiser Control Cockpit service is installed is configured so that the IP ad- dress is assigned automatically, rather than a static config- uration.

After several minutes, all receivers in the network will receive a link-local address in the range of 169.254.x.x. You can see this address in the Network Settings menu on the receiver (see Using the operating menu of the receiver).

Setting up the receiver This sections describes how to set up the receiver.

You can also install the receiver in a fixed location, e.g. in a 19" rack. You can find more information about installing the re- ceiver in a fixed location under: Installing receivers in a rack.

Affixing the device feet

Only affix the device feet if you are setting the receiver up in the stand-alone position instead of installing it in a 19" rack. The device feet will get in the way if the receiver is installed in a rack.

To affix the device feet: Clean the recesses for the device feet at the base of the re-

ceiver. Affix the device feet to the recesses of the receiver. Place the receiver on a flat, horizontal surface.

The device feet will adhere reliably to the receiver only after some time. Avoid moving the receiver during this time.

ATTENTION

Risk of staining furniture surfaces

The device feet my leave stains if they come into contact with furniture.

Do not place the receiver on delicate surfaces.

Attaching the mounting angles

The mounting angles are designed to help protect the operat- ing elements from damage or deformation, e.g. if the receiver is dropped. We therefore recommend always attaching the mounting angles, even if you do not want to mount the receiver into a rack.

To fasten the mounting angles: Unscrew and remove the two recessed head screws on

each side of the receiver. Secure the mounting angles to the sides of the receiver us-

ing the previously removed recessed head screws.

SL Rack Receiver DW

75

Make sure that the angled ends of the mounting angles point forward.

Installing receivers in a rack This chapter describes how to install a single receiver or two receivers side by side in a rack.

You can also set up the receiver without installing it in a fixed location. You can find more information about setting up the receiver under: Setting up the receiver.

ATTENTION

Danger due to high temperature, mechanical loading or electric leakage currents

When rack mounted, a receiver can be damaged by excessive heat or mechanical stress.

Make sure that the temperature within the rack does not exceed the permissible temperature limit specified in the specifications.

Make sure that the receivers in the rack are not subject to mechanical stress.

Make sure that circuits are not overloaded by providing overcurrent protection if necessary.

Make sure that the sum of the leakage currents of all power supply units do not exceed the allowable limit values by grounding the rack via an additional ground connection, if necessary.

Controlling and monitoring the CHG 4N char- ger over the network You can connect the CHG 4N charger to a network using a router or switch, which allows you to monitor and control the accupacks charge level using the Sennheiser Control Cock- pit software and to modify the CHG 4N chargers network con- figuration.

For more information on controlling a system in the network using the Sennheiser Control Cockpit software, refer to the instruction manual of the software.

Please note that the host PC on which the Sennheiser Control Cockpit Service is installed must be in the same network as the devices that are to be monitored and controlled.

Connecting the CHG 4N charger to the network

To connect the charger using the Sennheiser Control Cockpit app: Connect a standard network cable (at least Cat 5) to the

Ethernet socket of the charger. Connect the other end of the network cable to the network,

e.g. to a switch or router, or directly to a PC to make initial configuration easier.

Integrating the CHG 4N charger into a network with DHCP

If a DHCP server is active in the selected network, the CHG 4N charger receives an IP address automatically.

The CHG 4N charger is automatically detected in the Sennhe- iser Control Cockpit once it is connected to the network, since the CHG 4N is delivered with mDNS activated by default.

You can deactivate mDNS after you have configured the char- ger once. The IP address may change during operation, de- pending on the lease time and the DHCP server settings.

mDNS = multicast Domain Name System: resolves host names to IP addresses within small networks that do not include a local name server. Used for auto- matic device discovery.

Integrating the CHG 4N charger into a network with- out DHCP using Auto IP

If there is no DHCP server in the network and you are working with automatically generated IP addresses, please observe the following information.

Ensure that the host PC on which the Sennheiser Control Cockpit service is installed is configured so that the IP ad- dress is assigned automatically, rather than a static config- uration.

After several minutes, all chargers in the network will receive a link-local address in the range of 169.254.x.x.

The CHG 4N charger is automatically detected in the Sennhe- iser Control Cockpit, since the CHG 4N is delivered with mDNS activated by default.

You can deactivate mDNS after you have configured the char- ger once.

mDNS = multicast Domain Name System: resolves host names to IP addresses within small networks that do not include a local name server. Used for auto- matic device discovery.

Some basic routers with an integrated DHCP server require more time to start. In this case, the Speech- Line devices may initially receive an automatically as-

The CHG 4N charger

191

signed IP. Once a DHCP server is available, however, the IP addresses assigned by the server will be used.

Integrating the CHG 4N charger into a network with- out DHCP using Fixed IP

If there is no DHCP server in the network and you are working with fixed IP addresses, please observe the following informa- tion.

The CHG 4N charger is delivered with automatic IP assign- ment configured by default. After adding it in the Sennheiser Control Cockpit, you can reconfigure it to Fixed IP. To do so, proceed as described above: Integrating the CHG 4N charger into a network without DHCP using Auto IP.

If you wish to do this, you must temporarily reconfigure the host PC on which the Sennheiser Control Cockpit is installed to automatic IP assignment.

If the CHG 4N charger is visible in the Sennheiser Control Cockpit, you can do the IP configuration manually:

Change the IP settings under Device Details -> Network in the Sennheiser Control Cockpit.

Connecting a pre-configured CHG 4N charger to the Sennheiser Control Cockpit

If mDNS is activated (factory setting), the CHG 4N charger is automatically detected in the network.

If the charger has been reconfigured according to one of the procedures described above and mDNS has been deactivated, you can add the charger manually using the Add Device func- tion in the Sennheiser Control Cockpit.

To add the charger in the Sennheiser Control Cockpit: Use the Add Device function in the Sennheiser Control

Cockpit and enter the pre-configured IP address.

Resetting the CHG 4N chargers network settings

To reset the network settings to their factory defaults: Use a pointed object to press the small reset button for at

least one second. The settings will be reset once you release the reset button. The factory settings are restored: Automatic IP assignment mDNS is activated
