Conference audio systems are widely known and are usually used in political or economic debates, at fairs and wherever a plurality of people discuss with each other supported by a microphone-amplifier-loudspeaker system. In known systems each delegate of a conference has a seat with a working table in which the microphone and the loudspeaker is integrated. A conference audio system is proposed comprising a plurality of delegate units (2), each delegate unit (2) having a delegate loud-speaker (5) and/or a delegate microphone (4), a control means (3, 15) for distributing at least one audio signal from at least one of the delegate microphones (4) or another sound source to a plurality of the delegate loudspeakers (5), the plurality of delegate loud-speakers (5) generating a common audio atmosphere, delay means (16) operable to add a time delay on the audio signal, whereby the time delay is dependent from the distance between the position of the delegate microphone (4) or sound source, respectively, generating the audio signal and the individual delegate loudspeaker (5) position.
