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.

Components

The MobileConnect system consists of these components.

ConnectStation

The ConnectStation is the central unit for integrating different audio

streams and transmitting them vie WiFi access points to any personal mo-

bile device.

Components

MobileConnect App

►

Available for iOS / Android – and for free. The MobileConnect App is easy

to use and convenient for everyone. It is fully compatible with iOS and And-

roid accessibility modes where visual impairment support is required. Its

advanced Personal Hearing Assistant is based on technologies by Fraun-

hofer Institute IDMT and allows for individual audio adjustments via a sim-

ple and intuitive touchscreen user interface.

►

Components

Access Point (optional)

►

The Ruckus WiFi Access Point is used for wireless transmission of the au-

dio signals to the users‘ personal devices. It is only necessary if the system

is used in Standalone Mode.

The access point is only delivered with the +WiFi country variants (see

"Country variants").
