Portable tape recorder '' Spring-212S ''.

Cassette tape recorders, portable.The portable cassette stereophonic tape recorder "Vesna-212S" in 1985 was experimentally produced by the Zaporozhye electrical machine-building plant "Iskra". The tape recorder of the II group of complexity "Spring-212-stereo" (in the documentation and on the body of the model is simply "Spring-212") provides recording of both mono and stereo phonograms with subsequent playback of the recording through the built-in speaker. Possibility is provided for: automatic stop of the tape recorder at the end of the tape in the cassette or the cassette malfunction, as well as during the operation of the "Memory" device; control of the recording level by pointer and peak indicators on LEDs; the use of magnetic tapes of two types; switching tape types; control of supply voltage by a dial indicator; automatic adjustment of the recording level; separate tone control for high and low frequencies. The noise reduction system provides a reduction in the noise level during the playback of the recording. The presence of a three-decadal tape consumption counter with the "Memory" device allows you to quickly find the necessary records and determine the tape consumption. Power supply from 8 elements 373 or from the AC mains from the built-in rectifier. The body of the tape recorder is made of impact-resistant polystyrene. The set includes two MK-60 cassettes. Magnetic tape type A4205-3 or A4212-ZB. The speed of the magnetic tape is 4.76 cm / s. Maximum recording or playback time 2x30 min. Operating frequency range when using magnetic tape: А4205-3 - 40 ... 12500, А4212-ЗБ - 40 ... 14000 Hz. Knock coefficient ± 0.25%. Linear output harmonic distortion 4.0%. The relative level of noise and interference in the recording and playback channel: without SN when using a magnetic tape A4205-3 -50 dB, A4212-ZB -52 dB, with SN -53 and -55 dB, respectively. Output power: maximum 2x4 W, nominal 2x1.5 W. Supply voltage: from 12 V elements, from 220 V electrical network. Power consumption from the network - 10 W. The dimensions of the tape recorder are 480x195x155 mm. Weight 6 kg. The price is 320 rubles. The tape recorder was released in a limited series (about 300 copies) after which its production was transferred to the Zaporozhye tape recorder plant "Vesna".
