Tape recorder '' MEZ-6 ''.

Tape recorders and radio tape recorders.The MEZ-6 tape recorder was developed in 1950 by the Moscow Experimental Plant for subsequent release. The tape recorder, designed in the form of a console, contains a tape drive, a recording amplifier and a playback amplifier. The inclusion of external circuits in the tape recorder is carried out using connectors, and the device (including amplifiers) is controlled from the top panel of the console using simple transfer devices. The amplifiers are assembled according to the original circuits. They are distinguished by high quality indicators and are economical in nutrition. Each amplifier is mounted together with a selenium rectifier. Thanks to the special design of the screen of the reproducing head, it was possible to avoid the use of an antiphonic loop. The kinematic diagram of the tape recorder contains three electric motors. In terms of such electro-acoustic indicators as frequency response, nonlinear distortions, level of intrinsic noise, the MEZ-6 tape recorder exceeds the requirements for class 1 equipment. The pass-through frequency response of the recording-playback channel in the range from 30 ... 12000 Hz has an unevenness of no more than ± 1.5 dB. The harmonic coefficient is 0.8% at a frequency of 400 Hz with 100% modulation of the sound carrier. The level of intrinsic noise in the through channel after erasing the old record is minus 60 dB. The speed of the magnetic tape is 770 mm / sec. The duration of one roll of tape is 22 minutes. The device is powered from a 220 V AC mains. Power consumption from the mains does not exceed 130 W. The quality indicators of the tape drive mechanism are the same as in the previously produced MEZ-2 tape recorder. The block of heads is removable and equipped with adjustment of the position of the heads.
