    • Remote control & troubleshooting
      Sennheiser Control Cockpit gives you full overview and control of all devices in your entire campus-wide setup at all times. Use the Monitoring View, for example, to monitor all relevant information about your devices in any room in real time. Remote maintenance makes it easy to identify and resolve problems such as forgotten mute switches. The notifi cation function automatically sends you information about critical events, such as low battery levels, via e-mail or SMS, and allows you to react before a failure occurs.

      Advanced System Automatics
      The advantages of a digital wireless system are demonstrated by our advanced system automatics. For easiest set-up, Automatic Frequency Management performs an on-site real-time scan on startup to fi nd free frequencies. During operation, Automatic Interference Management changes seamlessly to a free channel in case of frequency disturbances. Manual voice level adjustment is no longer necessary thanks to Automatic Audio Level Management.

      Multi-room mode
      SpeechLine Digital Wireless features two operating modes. The Automatic Mode ensures the simplest startup and a reliable, maximum range for up to 20 simultaneously used links (dependent on regional regulations). In Multi-Room Mode, the transmission power is adjusted to the room size to allow infi nite scaling options from small meeting rooms to large campus-wide setups.
