Sound Recorder-Reproducer RD-365/UN (hereafter referred to as the recorder) is an all transistorized portable
tape recorder-player designed for entertainment as well as instructional purposes. It is used to magnetically record
sound on iron oxide coated plastic recording tape. Sound recordings may be made using a microphone, or by record-
ing audio directly from a telephone line, phonograph, radio or motion picture equipment. Reproduction is provided
by a self-contained amplifier and speaker. Any portion of the tape may be repeatedly played back in whole or in
part, or the tape may be stored as a permanent record. The tape can be played back immediately without further
processing, When recorded information is no longer desirable, the recorder will automatically erase old informa-
tion as a new recording is made. The old information can also be erased without recording any new information.
The recorder can be used with slide (or film strip), or motion picture narration by using the microphone input to re-
cord the narration, or by using a prerecorded tape that has been specially prepared for slide or motion picture film.
An external speaker jack is provided for use of external speakers to allow a larger audience area coverage.
