1. A dedicated, non-switched, multi-station audio distribution apparatus that allows a plurality of users to simultaneously sample different audio tracks comprising:

  • (a) at least two listening stations, said at least two listening stations each consisting essentially of a user input, a visual display to display informational data corresponding to said user input, an audio output such that an analog audio signal corresponding to said user input may be heard, a keypad to enter apparatus adjustments, and a first microcontroller connected to said user input, said visual display, said audio output, and said keypad;

    (b) a data control device adapted to retrieve informational data corresponding to each of said user inputs, to retrieve digitized audio material corresponding to each of said user inputs, and to produce responsive outputs consistent with each of said apparatus adjustments;

    (c) at least one low voltage listening station interface device, disposed between said data control device and said at least two listening stations, further consisting essentially of a second microcontroller, a digital interface, an analog interface, a digital to analog converter, and a data control device interface, said digital interface, digital to analog converter, and data control device interface being connected to said second microcontroller, and an analog stereo amplifier within said low voltage listening station interface device, connected to said digital to analog converter and to said analog interface;

    (d) low-voltage cabling connecting said listening station interface device to each of said at least two listening stations; and

    (e) a dedicated, non-switched connection connecting said data control device to said listening station interface device.
