Tape recorders '' Nota '' and '' MP-64 ''.

Tape recorders and radio tape recorders.The Novosibirsk Electromechanical Plant has been producing tape recorders "Nota" and "MP-64" since 1964, and the Omsk Electrotechnical Plant named after V.I. K. Marx. MP "Nota" is intended for recording and playback of phonograms from a microphone, pickup and radio transmission line. To listen to phonograms, the set-top box must be connected to the LF amplifier of the receiver or TV. The set-top box uses a 2-track recording system. The speed of the magnetic tape is 9.53 cm / sec. The attachment is equipped with reels No. 15, which can hold 250 meters of tape. The duration of the sound recording is 2x45 min. The nominal output voltage of the amplifier is 0.6 V, the band of recorded and reproduced frequencies on a tape of type 6 is 63 ... 10000 Hz, the nonlinear distortion factor is 3%; the level of noise and background is not worse than -40 dB. The detonation coefficient of the CVL is 0.6%. The set-top box is powered from a network with a voltage of 127 or 220 V, consuming 50 watts of power. The dimensions of the attachment are 350x260x140 mm. Weight 7.5 kg. The tape recorder "MP-64" does not differ from the "Nota" prefix in terms of its electrical circuit and design, but it does not have a case. The model was produced for various industrial needs, for example, for embedding in special school desks for learning a foreign language. Since 1965, the Berdsk Radio Plant has been producing the "Record" radio tape recorder where the "MP-64" tape recorder was built in. In 1966, the prefix, after a slight improvement in the electrical circuit, became known as "MP-64A".
