Multi-station audio distribution apparatus

摘要

A multi-station audio distribution apparatus having at least two listening stations, a data control mechanism and a listening station interface mechanism disposed between the listening stations and the data control mechanism. Each of the listening stations has a user input in the form of a bar code scanner to enter an audio material selection and each has an audio output. The data control mechanism retrieves digitized audio material corresponding to each of the user's audio material selections. The listening station interface mechanism transfers the user's inputs from each of the listening stations to the data control mechanism, receives the digitized audio materials corresponding to each user's input from the data control mechanism, converts the digital audio materials to analog audio signals and transfers the analog audio signals to each of the respective listening stations for the audio output.
