Sennheiser expands ADN discussion system
Sennheiser has released a new system update for the ADN discussion system which can be downloaded free of charge from its website.
The manufacturer has also unveiled the ADN PS power supply unit, which will be available from autumn 2011. The 19-inch rack-mount unit makes it possible to build conference systems with up to 400 terminals.
The new software enables the central unit of the ADN system to communicate directly with media control devices via an open protocol, allowing it to be integrated into existing audio/video control systems. Users can operate all functions with their usual control panel. XLR Mix Minus mode removes echo effects in which speakers hear their own output with a delay by deleting the speaker’s own voice signal from the sum of the conference signals.
For relatively small conferences which are transmitted to an external location, loudspeaker amplification of the speakers’ contributions is not required in the conference room itself. Amplification is only necessary for the external participants. The Mic Loudspeaker Mute mode ensures that the speaker’s own contributions are only transmitted to the external participants and not through the loudspeakers of the terminals. Only the speech contributions of the external participants are played through the loudspeakers.
The ADN PS power supply unit supplies power to between two and 20 chairman and delegates terminals in a ring set-up or four and 15 terminals terminals with a line connection. Up to 15 ADN PS units can be cascaded to power up to 400 terminals.
