Universal recorder-player "UMP-1" was developed in IV-apt 1954. Having a universal tape recorder "UPM-1" you can record any broadcast and play it right away. If the recording is no longer needed, 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 broadcasting line, a radio receiver or a microphone and plug the device's power plug into an electrical outlet. When you have finished recording, you rewind the tape to the beginning of the recording and switch the control knobs to playback to listen to the recording. A universal tape recorder makes it possible not only to record and play sound on a magnetic tape, but also to play grammar records, regular and long-playing. In addition, when playing records, you can simultaneously copy them to a magnetic tape. The device can work with double speeds of tape movement: 19 and 8 cm / sec. With a decrease in the speed of the tape, the sound quality decreases, so low speed is used when recording speech. Two disk rotational speeds of 78 and 33 rpm make it possible to play ordinary and long-playing records. The presence in the apparatus of the amplifier and loudspeaker, make it possible to use it as a shifter. The prototype model of the UMP-1 recording apparatus was designed and manufactured by one of the plants of the Ministry of Electrical Engineering and was successfully tested at the VNII of Sound Recording, the Ministry of Culture of the USSR.
