Recorder-prefix "Rostov-121-stereo" prepared for release from 1988 by the Rostov plant "Pribor" Stereophonic reel 2-speed tape recorder-prefix of the first group of complexity with the use of integrated circuits "Rostov-121-stereo" provides recording of mono and stereo phonograms, with subsequent reproduction of magnetic recording through the UCU or stereo amplifiers with speakers; It can also be used independently for listening to phonograms via stereophones. In MP used: three-engine tape drive mechanism; automatic control of the tension of the magnetic tape and automatic stabilization of the tape rewind speed; glass ferrite magnetic heads; LED display showing additional information on the operation of the MP; electronic logic control of work modes, allowing selection of work modes in any sequence, as well as an electronic tape consumption meter. It is possible to: perform trick recordings by mixing signals; control the level of recording or playback of electronic fluorescent indicators; light indication of operating modes "Record", "Working stroke", "Reverse stroke", "Pause", "Stop"; wireless remote control on infrared rays modes of LPM, volume, balance, timbre at higher and lower frequencies, at an adjustable line input and output for connecting stereo phones; switching the size of the used coil with readiness indication on the display; automatic setting of the recording level, with indication on the display; control using a pseudo-touch switch of all modes of operation of the tape recorder; determining the presence of a phonogram in rewind mode; stopping the tape when the counter reaches zero; tape rollback to zero meter readings with subsequent reproduction; automatic reproduction of phonograms, between the zero mark and the address on the counter; automatic cyclic transition to the mode "Reverse travel" from the mode "Working travel" and vice versa according to the counter reading; tape recorder operation in "Amplifier" mode; network indicator.Type of magnetic tape A4416-6B. Coil number 18; 22. The speed of the magnetic tape 19,05; 9.53 cm / s. The maximum recording and playback time is 2x45; 2x90 min.
