Sennheiser has announced the ADN-W (Audio Distribution Network Wireless), a wireless extension of its ADN conference system, which uses both the 2.4GHz and 5GHz frequency range for wireless transmission.

ADN-W is a hybrid solution that enables wired components to be combined with wireless ones, and allowing existing ADN systems to be expanded by adding ADN-W components. All discussion units can be directly controlled from the same central unit. Replaceable rechargeable batteries guarantee an operating period of at least 20 hours for ADN-W discussion units.

Up to 150 wireless discussion units can be used simultaneously, and further units can be added during the conference itself. The Ethernet interface allows the conference system to be controlled intuitively from a PC or media control systems.

‘It goes without saying that ADN-W also provides optimum speech clarity,’ says Jens Werner, Portfolio Manager Integrated Systems Division at Sennheiser. ‘The icing on the cake is the ME 36 super-cardioid. This is now available as a gooseneck solution exclusively for ADN-W and guarantees a level of audio quality that is unsurpassed on the market.’

In order to exclude unwanted listeners, audio transmission is protected using AES 128-bit encryption.

The ADN-W Case contains dedicated, stackable modules for all system components, as well as integrated units for re-charging the discussion units. The sturdy charging and transport case can be individually adapted to the size of the system.

The Sennheiser ADN-W conference system will be available from May 2014.
