Tape recorder-set-top box `` Radio engineering MP-7301S ''.
Cassette tape recorders, stationary.The tape recorder "Radiotechnika MP-7301-stereo" has been produced since 1989 by the Riga Radio Plant named after A.S. Popov. Stereophonic tape recorder-set-top box `` Radiotekhnika MP-7301-stereo '' is designed for recording and reproducing sound on magnetic tapes such as Fe2O3 or CrO2, placed in compact cassettes. MP allows you to record from a microphone (recommended by IEC-11SN), an electrophone, a TV, a receiver, a tuner, an electric player, another tape recorder and from a broadcast line directly or through an UCU. Optimal conditions for the operation of the MP and the achievement of maximum performance are ensured when working together with the blocks of the Radiotekhnika complexes. The tape recorder has a key switch for operating modes, a luminescent indicator of the recording and playback level with an electronic tape consumption meter, a separate recording level controller for channels, an active noise reduction system, a tape type switch. MP also has the following auxiliary devices and functions: The ability to temporarily stop the tape. Device for quick disconnection of the recording source. Automatic stop at the end of the tape. Possibility of connecting stereo telephones (recommended type is TDS-7). "Memory" device in the tape consumption meter. The main characteristics of the MP: The nominal speed of the magnetic tape is 4.76 cm / s. The deviation of the speed of the magnetic tape from the nominal value is not more than ± 1.9%. Knock coefficient no more than ± 0.19%. The operating frequency range at the linear output is not more than 40 ... 14000 Hz. The relative level of noise and interference in the recording-playback channel when the noise reduction system is on is not more than 60 dB. The relative level of penetration from one stereo channel to another at a frequency of 1000 Hz is not more than 26 dB. The relative erasure level is 60 dB. The output voltage of the linear output is 500 mV. The nominal EMF of the signal source at the microphone input is 0.2 mV. The minimum EMF of the universal input is 0.2 V. The minimum output voltage for recording from the broadcast line is 10 V. Power consumption is 15 W. MP dimensions - 430x82x360 mm. Weight without packaging 6.9 kg, with packaging 8.5 kg.
