Reel-to-reel tape recorder '' Rostov-112-stereo ''.
Reel-to-reel tape recorders, stationary.Reel-to-reel tape recorders, stationaryIn 1988, a reel-to-reel tape recorder "Rostov-112-stereo" was produced by the Rostov plant "Pribor" (~ 10 pieces). Stereophonic tape recorder of the 1st group of complexity with the use of integrated circuits "Rostov-112-stereo" provides recording of mono and stereo phonograms with their subsequent playback through external speakers or stereo telephones. The tape recorder uses: three-motor CVL; automatic control of magnetic tape tension; automatic stabilization of tape rewinding speed; electronic-logical control of operating modes, which allows you to select operating modes in any sequence; glass-ferrite magnetic heads, characterized by increased wear resistance, as well as an electronic tape consumption meter with devices "Memory", "Autosearch". It is possible to: perform trick recordings by mixing the signal from the "Microphone" input and any other; automatic stop when the tape ends or breaks; control of the level of recording or playback by electronic luminescent indicators; light indication of operating modes "Record", "Working stroke", "Pause", "Stop"; control by means of a pseudo-sensor switch the LPM operating modes; remote control of operating modes: "Rewind", "Play" and "Stop"; control of the recorded signal in the "Record" mode; automatic shutdown of external speakers in case of amplifier malfunction; operation of the tape recorder in the "Amplifier" mode; light indication of inclusion in the power grid. The presence of separate magnetic recording / playback heads makes it possible to listen to the recorded signal during recording. The set of the tape recorder also includes two reels (including a reel of magnetic tape). Magnetic tape type A4416-6B. Coil number 18; 22. The speed of the magnetic tape is 19.06; 9.53 cm / s. Maximum recording time during playback 2x45; 2x90 min. Working range of sound frequencies 25 ... 25000; 40 ... 14000 Hz. Knock coefficient no more than ± 0.09 and ± 0.15% Harmonic coefficient at the linear output no more than 1%. The relative level of noise and interference in the recording-playback channel is -63 dB. Output power: maximum 2x50 W, nominal 2x15 W. The input impedance of an external speaker is 4 ohms. Power consumption 200 watts. Dimensions of the model are 510x417x225 mm. Weight 23 kg. Since 1990, according to the new GOST, the plant has been producing the Rostov MK-112S tape recorder, a complete analogue of the one described.
