Dampened transducer support apparatus for message announcing system
 An announcing system including a message drum with a plurality of listening-recording heads radially spaced around the message drum, each of the listening-recording heads being adapted to traverse a portion of the surface of the message drum, and each of the listening-recording heads having an erase head associated therewith. A master timer is provided, and synchronizing means associated with the message drum provides a synchronizing pulse to maintain proper relationship between the master timer and rotation of the message drum. A control circuit allows a recording station to be selectively connected to the listening-recording heads for recording a message on a message track of the message drum and a subscriber station to be selectively connected to the listening-recording heads for listening to a message that has been recorded on the message drum. The control circuit, under the influence of the master timer, assures that the entire message on the message track will be played each time a subscriber line is connected to the system, and that sufficient time is allowed for mechanical operations of the apparatus between each cycle of the apparatus.
