The cassette tape recorder "Orel MP-201-stereo" was planned to be produced from 1985 by the Dnieper engineering plant. Records mono and stereo phonograms with the subsequent playback of the recording via the UCU with speakers and through headphones. MP used: compander noise reduction system, which expands the dynamic range of phonograms in recording-playback mode; dual level controls that allow you to quickly and synchronously control the recording level and volume in both channels; an electronic logical quasi-sensor control device for operating modes, allowing selection of operating modes in any sequence. It is possible to: automatically stop the operation of the MP at the end of the magnetic tape and malfunction of the cassette; control of level Z / V on arrow indicators; light indication of operating modes, indication of the inclusion of UWB; using 3 types of magnetic tapes; switching tape types; adjusting the bias current for a specific type of tape. The presence of separate magnetic heads makes it possible to listen to the recorded signal while recording. The presence of a three-tape tape counter with a reset button allows you to quickly find the necessary records and determine the consumption of a magnetic tape. The MP kit includes 3 MK-60 cassettes. Type of magnetic tape A4205-3; A4212-ZB. The maximum recording or playback time is 2x30 minutes. The working range of sound frequencies when using a magnetic tape of the type: Ð4205-3 - 31.5 ... 12500 Hz, Ð4212-ЗБ - 31.5 ... 14000 Hz. Knock factor ± 0,2%. The harmonic coefficient at the linear output of 2.5%. The relative level of noise and interference in the recording-playback channel when using A4212-ZB magnetic tape, dB: without noise reduction system -54, with WB-65 system. Power supply 220 V. Power consumption 40 watts. Dimensions MP 350h290h131 mm. Weight 7.9 kg.
