Tape recorder-set-top box `` Radio engineering MP-7220S ''.
Cassette tape recorders, stationary.The tape recorder "Radiotekhnika MP-7220S" has been produced by the Riga PO "Radiotekhnika" since the 1st quarter of 1987. The two-cassette tape recorder-set-top box "Radiotekhnika MP-7220-stereo" is intended for recording sound phonograms from various sources on magnetic tape in MK cassettes, with subsequent playback through an external UCU with an AC. Block LPM "A" provides only reproduction, block "B" recording and reproduction of phonograms. The set-top box tape recorder has: Compander noise reduction system. LED indicator for recording and playback levels. Ability to work with two types of tapes. Pseudosensory control of LPM operating modes. Automatic sequential playback of two cassettes (A-B, B-A). Automatic phonogram search mode. Formation of a normalized pause during recording. Electronic counter of magnetic tape consumption. There is a complete hitchhiking. Remote control device for all modes of LPM "A" and "B" on infrared rays with a range of up to 5 meters. Brief technical characteristics: The nominal speed of the magnetic tape is 4.76 cm / s. The average deviation of the speed of the magnetic tape from the nominal value is not more than ± 2%. Knock coefficient no more than ± 0.19%. The full effective frequency range at the linear output for a tape with a working Cr layer is not more than 40 ... 14000 Hz. The tape recorder is powered from the AC mains. The overall dimensions of the MP are 430x350x122 mm. Its weight is 6.8 kg. The radiotekhnika MP-7221S tape recorder, produced since the 1st quarter of 1990, differs from the one described only by the absence of a remote control. Both versions of the MP were produced in two color options.
