Remote Microphone Network Station Control

In a remote microphone network system having automatic media change capabilities, recorder seizure is facilitated without increasing the number of lead lines connecting remote microphones to the remainder of the system.

Remote microphones 1 are connected to a control unit 2 having a decode and time-delay circuit 4. The output of control unit 2 is to a recorder having a decode 3, and a media feed drive 5 for changing the media upon a signal applied from decode 3 to media feed drive 5. Seizure of the recorder is determined by decode and time-delay circuit 4. Each microphone 1 has a media feed control switch for controlling feed and NOT feed. During a recording operation, other switches such as record, review, etc., are manipulated in an ordinary manner. When it is either desired to change the media or stop the machine, the feed switch is positioned in the feed position and the output of the media feed drive is as illustrated. Seizure will be maintained by a remote microphone as long as the time delay does not exceed defined limits. When this time is exceeded, the system is available for another of the microphones 1. Therefore, an existing control switch and its associated connections (lead lines) serve two functions, and the necessity for additional lead lines is eliminated.
