ABSTRACT:
A programmable annunciator device for periodic fade-in of specific message segments in a continuous broadcast or background audio. The device utilizes a tape cassette and transport with reel turns count circuitry providing tape position data. The cassette is programmed to include two tracks of successive messages of preselected time length, each identifiable by reel turns count. The reel turns count for each message position is stored in read only memory while random access memory is programmed to include code identifier and address data for each message position. In program mode, the desired audio is recorded at each message position for selective playback. In operate mode, an interval timer initiates playback of the selected messages in sequence and timing as selected by the operator.
