At ISE 2015, Sennheiser has unveiled SpeechLine Digital Wireless – a wireless digital microphone designed exclusively for speech applications. And, SpeechLine Digital Wireless has an Automatic Frequency Management feature that automatically searches for free frequencies on-site, thus eliminating the need for time-consuming frequency planning in advance.
Integrated Audio Level Management automatically adapts the system to the application scenario and the speaker. As a result, the system ensures optimum speech intelligibility at all times. Also, network integration enables the system status to be remote controlled and monitored at a glance at any time using the special app “Wireless System Remote” (WSR), AMX or Crestron — for example to show the current reception quality or the battery’s state of charge.
If wireless transmission is disturbed, Automatic Interference Management automatically and seamlessly switches the system to an alternative free frequency. The lithium-ion battery technology used in SpeechLine Digital Wireless provides a battery life of more than 15 hours. In addition to various flexible charging possibilities, the battery can also be conveniently recharged via USB if required, making it much easier to arrange several consecutive lectures. Optimum speech intelligibility is guaranteed at all times by various selectable sound profiles and sound processing algorithms, such as presets for bass-intensive male voices or high female voices.
Integrated with 256-bit AES encryption, the mic also operates in the license-free, future-proof 1.9 GHz frequency band, and no registration is required.
SpeechLine Digital Wireless is available as a handheld or Lavalier microphone or as a headset. All three sets include a mobile transmitter unit — a handheld or a bodypack system, a battery as well as a receiver station that can easily be integrated.
The SpeechLine Digital Wireless sets and the app “Wireless System Remote” (WSR) will be available in June. Here’s a video we shot of it at ISE last week.
