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.

Outstanding Battery Management
With SpeechLine Digital Wireless, empty batteries are a thing of the past. With 15+ hours of battery life, SpeechLine Digital Wireless microphones are ready for even the longest working day. The network charger serves as a convenient storage device for the microphones that are currently not in use. Sennheiser Control Cockpit provides a full overview of the battery status of all microphones on the campus at all times.

Dedicated to speech
SpeechLine Digital Wireless is made for the spoken word. Speech optimized Sennheiser microphone capsules and built-in equalizers with presets for female and male voices ensure optimal speech intelligibility in every situation. The SpeechLine Multi-Channel Receiver automatically mixes multiple speakers at the same time with an integrated Automatic Audio Level Management so that each person can be clearly understood.

No hardware interaction required
All SpeechLine Digital Wireless microphones are very easy to use. The presenter simply takes the microphone out of the charging station and is immediately ready to go. The end user does not need to have access to the receiver. Avoid classic user errors by installing the receiver in a not publicly accessible location. For the Rack Receiver, for example, this would be a lockable IT or AV rack. The Multi-Channel Receiver can be mounted easily and unobtrusively on the wall or ceiling.

License-free 1.9 GHz
SpeechLine Digital Wireless uses the license-free 1.9 GHz frequency range. This RF standard is also used by wireless telecommunications systems and is considered the most future-proof frequency band for wireless microphone systems.

No additional hardware needed
Save money on additional hardware with SpeechLine Digital Wireless. Use the integrated DSP with an EQ and included presets for male and female voices. MultiChannel Receiver features an auto-mixer and built-in antennas.
