ABSTRACT:
Apparatus that includes a magnetic tape recorder is also provided with FM and AM radio signal tuners and a TV audio signal tuner. The signals received by any of these tuners can be either recorded or monitored independently. However, when an FM signal is being recorded in the magnetic tape recorder, the apparatus is so constructed that a TV signal cannot be monitored by the TV signal tuner. Conversely, when a TV signal is being recorded, the FM tuner cannot monitor an FM signal. When an AM signal is being recorded, either an FM or a TV signal can be monitored and, conversely, when either an FM or a TV signal is being recorded, an AM signal can be monitored.
