  • Fjärrkontroll och felsökning
    Sennheiser Control Cockpit ger dig full överblick och kontroll av alla delar i din högskolas nätverk vid alla tillfällen. Du kan använda Monitoring View för att i realtid överblicka all relevant information om dina enheter i vilket rum som helst. Fjärrunderhåll gör det enkelt att identifiera och lösa problem som exempelvis glömda mute-knappar. Meddelandefunktionen skickar dig automatiskt information om viktiga händelser, till exempel låga batterinivåer, via e-post eller SMS och låter dig reagera innan ett fel inträffar.
    
    Avancerad systemautomatik
    Fördelarna med ett digitalt, trådlöst system märks tydligt med vår avancerade systemautomatik. Installationen förenklas med hjälp av Automatic Frequency Management, som på vid start gör en sökning i realtid efter lediga frekvenser. Om störningar skulle uppstå under drift, byter Automatic Interference Management automatiskt till en ledig frekvens. Automatic Audio Level Management sköter volyminställningarna med automatik.
    
    Flerrumsläge
    Speechline Digital Wireless har två inställningslägen. Det automatiska läget gör det enkelt att komma igång och ger en stabil maximal räckvidd på upp till 20 samtidiga länkar (beroende på lokala regelverk). I flerrumsläget ställs sändningsstyrkan in efter rummens storlek för perfekt anpassning från små mötesrum till stora, heltäckande nätverk.

  • Enastående batterihantering
    Med SpeechLine Digital Wireless behöver du aldrig mer råka ut för urladdade batterier – över 15 timmars batteritid räcker även för riktigt långa arbetspass. Laddaren är också en praktisk förvaring för de mikrofoner som inte används. Sennheiser Control Cockpit håller kontinuerligt koll på laddningsläget för alla mikrofoner på Campus.
    
    Specialbyggd för tal
    SpeechLine Digital Wireless är gjord för det talade ordet. Taloptimerade mikrofonkapslar och inbyggda equalizers, med inställningar för manliga och kvinnliga röster, ger optimal hörbarhet för tal i alla situationer. SpeechLine Multi-Channel Reciever mixar automatiskt flera talare samtidigt med hjälp av Automatic Audio Level Management, vilket gör att varje talare hörs tydligt.
    
    Ingen ytterligare hårdvara krävs
    Alla SpeechLine Digital Wireless-mikrofoner är mycket enkla att använda. Talaren behöver bara ta ut mikrofonen ur laddningsstationen och börja prata. Användaren behöver inte ha tillgång till mottagaren. Undvik klassiska misstag genom att installera mottagaren på en plats som inte är tillgänglig för alla. En Rack Reciever kan till exempel placeras i ett låsbart IT-eller AV-rack. En Multi-Channel Reciever kan monteras diskret på en vägg eller i taket.

For connecting a transmitter with a SL MCR DW press the pair button of the dedicated channel in Sennheiser Control Cockpit and press and hold the pair button at the transmitter until the LED starts to blind red and green.

• Which audio outputs do I have?

  • To make the audio connection as easy and flexible as possible we provide several options. On the SL Rack Receiver DW we are offering XLR, TRS and phone jack as audio outputs. On the SL MCR DW all channels are available digital via DANTE and thanks to the integrated auto mixer also analog by using a 3- pin Phoenix 3.81.mm connector.

• Which batteries can I use?

  • The transmitter have an lithium ion battery in the delivery with which a transmitter can work up to 18h (depending on the device).

• How can I use more than two receivers?

  • For the case that more than two SL Rack Receivers DW are needed please use the AWM 2 or AWM 4 together with our combiner SL PASC 2 or SL PASC 4.

• What kind of antennas are avaiable?

  • As remote antenna the AWM 2 and AMW 4 is recommended. You can use one receiver with the AWM 2 and two receivers with the AWM 4. Together with a combiner the number of receivers can be increased. In any case additional cables are needed.

• How do I charge the transmitters?

  • We are offering 3 different chargers:
    - CHG 2 a two bay charger for handheld and bodypack
    - CHG 4N a four bay network charger for handheld and bodypack
    - CHG 2W a two bay inductive charger for tablestand and boundary.
    In addition the battery BA 10 (handheld) and BA 30 (body pack) can be charged via USB.

• Is there a possibility to monitor SpeechLine Digital Wireless?

  • With the Sennheiser Control Cockpit the receiver and the CHG 4N can be monitored and controlled remotely.

• Does the receiver support DHCP?

  • Yes, the receiver supports DHCP, Automatic IP and fixed IP. The Network mode can be adjusted in the receivers menu.

• Which headsets and lavaliers can be used with SL Bodypack DW?

  • You can use any headset or lavalier from Sennheiser. We recommend to use the SL Headmic 1 or MKE 1.

• How do I make a firmware update?

  • The firmware update is done via the Sennheiser Control Cockpit Software. As soon as a receiver has been upgraded to a new firmware the update of the portable transmitter will be done automatically when paired. In addition a transmitter can be upgraded via the Sennheiser Control Cockpit Software and the the CHG 4N.

• What is the difference between Master and Follower receiver?

  • To get the maximum number of microphones it is necessary to synchronize them with each other. Therefore, a master is needed, which controls all other microphones (follower).
    If you are using SL MCR DW the Master/Follower set up is done automatically.
    Please note: Any change on the Master/ Follower set up can only be done while the transmitters are switched off.
    
    If you are using only SL Rack Receiver DW please follow the steps below to ensure a valid Master / Follower configuration for your system:
    
    - Prepare and connect the antennas (if needed with AMW 4 and combiner)
    - Switch on one receiver and pair a transmitter. Wait until the LED at the receiver turns to green. This microphone will become the Master.
    - Switch on all other receivers, while the Master receiver is still on. All other microphones will become a follower automatically.
    
    IMPORTANT: As soon as the Master / Follower configuration has been done all receivers have to be switched on at the same time e.g. via a power strip.

• Do I have any kind of security feature?

  • Yes, the connection of a transmitter to a receiver is always AES 256 encrypted. The SL MCR DW offers the possibility to use IEEE 802.1x authentication for secured network deployment.

• What kind of antenna cables do I use?

  • SpeechLine Digital Wireless is using Reverse-SMA connectors due to regulatory reasons at the SL Rack Receiver DW. Sennheiser is offering RG-58 antenna cables in 1m, 5m 10m and 20m. A length higher than 20m is not recommended because the cable attenuation will be too high.

• Does SpeechLine Digital Wireless supports Media Control systems?

  • Yes, SpeechLine Digital Wireless is using the Sennheiser Sound Protocol, which can be used for programming a media control system. Furthermore, Plug-Ins for Crestron and QSC are available.

• What does "automatic Gain" mean?

  • SpeechLine Digital Wireless adjusts the sensitivity at the microphone automatically to the most convenient level. That means you don't have to take care about gain anymore.

• How do I set up the IP address of a receiver?

  • The IP address can be set manually or automatically via DHCP. Furthermore, IPv6 and mDNS is supported.

• How do I change the network mode at the SL MCR DW?

  • Changing the network modes can be done via Sennheiser Control Cockpit or the Dante Controller from Audinate. In Sennheiser Control Cockpit select the SL MCR DW and browse to the Network settings tab. There any network setting incl. the network mode can be changed. In Dante Controller as soon as the SL MCR DW is selected go to the “network config” tab and select the required mode in the drop-down menu. Please note: A restart of the SL MCR DW is required after changing the mode.

• Is PoE daisy chained in the single cable mode?

  • No, PoE is not daisy chainable. For the case a second SL MCR DW an additional PoE injector is required. The audio and network data are daisy chained.

• Which PoE class is used with SL MCR DW?

  • IEEE 802.3af Class 3.

• Is it possible to use SL MCR DW and SL Rack Receiver DW in the same room?

• Why do I have the down mix digital and analog?

  • The automatic mixing of all audio channels offers the possibility to use up to 4 channels of Speechline Digital Wireless even if only one input channel is left in the DSP or audio mixer. To be as flexible as possible the down mix signal is available digital via Dante as well as analog. Due to this the integration of Speechline in existing infrastructures is very easy. The audio signal is equal on both outputs, but the level can be adjusted separately in Sennheiser Control Cockpit.
