ABSTRACT:
A portable tape recorder for remote location news-gathering including a rugged metal housing having operating controls and input-output connections located at one end for ease of access. An audio output suitable for direct interconnection to telephone circuitry is provided in addition to internal speaker and external headset audio output connections. A talk-over preamp operatively interconnects the microphone or other audio input to the recorder output when the recorder is in the pause mode facilitating the use of the recorder microphone for direct telephone line connection. This permits live reporter commentaries, introductions, or `wrap-arounds` to be conveniently interspersed with pre-recorded news story segments. The speaker audio output is muted in the talk-over mode to preclude acoustic feedback while reporter `side-tone` monitoring is available through the external headset or telephone handset connections.
