New operating software for Sennheiser’s Audio Distribution Network (ADN) discussion system includes various modes to ensure more convenient system handling and to enhance speech intelligibility in acoustically difficult conference situations.
The software is now available in 13 languages and can be downloaded free of charge from the Sennheiser website.
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.
The XLR Mix Minus mode improves the audio quality at conferences that take place at more than one location. When speech contributions are transmitted to an external conference location, this sometimes results in unpleasant echo effects in which speakers hear their own voice with a delay.
To prevent this, the XLR Mix Minus mode deletes the speaker’s own voice from the sum of the conference signals, allowing all participants to hear a clear voice signal without irritating echo effects.
The Mic Loudspeaker Mute is 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 loudspeaker of the terminals. Only the voices of the external participants are played through the loudspeakers.
