The radio tape recorder-prefix "Radiotekhnika MP-7220S" from I-kv 1987 was produced by the Riga software "Radiotekhnika". The two-cassette recorder-prefix "Radio Engineering MP-7220-stereo" is designed to record sound phonograms from various sources on a magnetic tape in MK cassettes, followed by playback through an external UCU with AC. The LPM "A" block provides only playback, the "B" block records and plays back phonograms. Tape recorder has: Compander noise reduction system. LED indicator for recording and playback levels. Ability to work with two types of tapes. Pseudo-sensory control of the modes of operation of the LMD. Automatic sequential playback of two cassettes (AB, B-A).

A 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 velocity of the magnetic tape is 4.76 cm / s. The average deviation of the tape speed from the nominal value is no more than ± 2%. Knock factor no more than ± 0.19%. The total effective frequency range at the linear output for a tape with a working Cr layer is no longer 40 ... 14000 Hz The power of the tape recorder is carried out from the AC network. Overall dimensions of MP - 430x350x122 mm. Its weight is 6.8 kg. The tape recorder-prefix "Radio Engineering MP-7221S" produced since I quarter of 1990 differs from that described only by the absence of remote control.
