Product overview
MobileConnect - Sennheiser's WiFi based system for your venue that en-
ables low-latency transmission of audio content to mobile devices such as
smartphones and tablets. With our real time audio streaming server and
the MobileConnect App, you can easily provide assistive listening for hea-
ring impaired, audio description for blind people, interpretation channels or
audio for silent screens to your venue as well as movie subtitles.
Sennheiser's MobileConnect system embraces the bring-your-own-device
(BYOD) principle enabling users to use their own mobile devices on the Mo-
bileConnect WiFi network. The system consists of a ConnectStation, a
central unit for integrating different audio streams and transmitting them
via WiFi access points to the personal mobile devices.
Typical applications
Assistive listening
Audio description
Interpretation / Multi-language audio
Digital signage / Silent screens

Features
Bring your own device
►
The streaming system adheres to the “bring your own device” (BYOD) phi-
losophy. That means that all the people in the audience can use their own
smartphones as receivers with their own headphones, and do not need any
additional hardware. This way, they don’t have to rent expensive equip-
ment and can use devices they are already familiar with. Of course, the
venue can also offer iPods or other rental devices.
Personal Hearing Assistant
Developed with Fraunhofer-Institut für Digitale Medientechnologie ID-
MT, the Personal Hearing Assistant allows for a truly intuitive sound ad-
justment. The audio signal can be adjusted easily according to individual
hearing needs – not only the volume of the audio signal, but also more so-
phisticated sound parameters that affect speech intelligibility.
