Universal tape recorder UMP-1.
Combined apparatus.The UMP-1 universal tape recorder was developed in the 4th quarter of 1954. Having a universal tape recorder UPM-1, you can record any radio program and play it right now. If the made recording is no longer needed, then it can be erased and a new more interesting program can be recorded on the same tape. Moreover, you can record your own or the voice of a friend, any speech, lecture, and more. All this is done simply and quickly, you connect your device to a broadcast line, a radio receiver or a microphone and plug the device's power plug into an electrical outlet. When you finish recording, you rewind the tape to the beginning of the recording and switch the control knobs to playback and listen to the recorded recording. The universal tape recorder makes it possible not only to record and reproduce sound on a magnetic tape, but also to play gramophone records, ordinary and long-playing ones. In addition, while playing records, you can simultaneously rewrite them to magnetic tape. The device can operate at two tape speeds: 19 and 8 cm / sec. As the tape speed decreases, the sound quality decreases, so slow speed is used when recording speech. Two disc rotation speeds of 78 and 33 rpm, make it possible to play regular and long-playing gramophone records. The presence of an amplifier and a loudspeaker in the apparatus makes it possible to use it as a vehicle. The prototype of the UMP-1 sound recording apparatus was designed and manufactured by one of the factories of the Ministry of the Electrotechnical Industry and was successfully tested at the All-Russian Research Institute of Sound Recording and the Ministry of Culture of the USSR. We could not find information about the serial production of this model.
