Reel-to-reel tape recorders, stationary.Reel-to-reel tape recorders, stationaryThe "Rostov-121-stereo" tape recorder has been prepared for release since 1988 by the Rostov plant "Pribor". Stereophonic reel-to-reel 2-speed tape recorder of the first group of complexity with the use of integrated circuits "Rostov-121-stereo" provides recording of mono and stereo phonograms, followed by reproduction of the magnetic recording through the UCU or stereo amplifiers with speakers; can also be used autonomously to listen to phonograms through stereo phones. The MP uses: a three-motor tape drive mechanism; automatic control of magnetic tape tension and automatic stabilization of tape rewinding speed; glass-ferrite magnetic heads; LED display showing additional information about the operation of the MP; electronic-logical control of operating modes, which allows the selection of the operating mode in any sequence, as well as an electronic tape consumption meter. It is possible to: perform trick recordings by mixing signals; control of the level of recording or playback by electronic luminescent indicators; light indication of operating modes '' Record '', '' Working stroke '', '' Reverse '', '' Pause '', '' Stop ''; wireless remote control on infrared rays by operating modes of LPM, volume level, balance, timbre at high and low frequencies, at an adjustable line input and output for connecting stereo telephones; switching the size of the used coil with indication of readiness on the display; automatic setting of the recording level, with indication on the display; control by means of a pseudo-sensor switch of all operating modes of the tape recorder; determining the presence of a phonogram in rewind mode; stopping the magnetic tape upon reaching zero meter readings; rollback of the tape to zero counter readings with subsequent playback; automatic repeated playback of phonograms, between the zero mark and the address on the counter; automatic cyclic transition to the "Reverse" mode from the "Working stroke" mode and vice versa according to the counter reading; operation of the tape recorder in the "Amplifier" mode; network indicator.
