The toy "Electronics" (stereophonic designer), presumably since 1977, has been produced by the experimental plant of the Novosibirsk Research Institute "Vostok". ,86e6f450b8cc469628ba70bf2947b049The "Electronics" set is intended for assembly by intermediate radio amateurs of a multi-band tone control, the so-called equalizer. ,86e6f450b8cc469628ba70bf2947b049These tone controls allow for greater fidelity in musical program reproduction than conventional controls. ,86e6f450b8cc469628ba70bf2947b049They make it possible to compensate to a certain extent for the irregularity of the frequency response of the radio complex as a whole, caused by one or another of its links. ,86e6f450b8cc469628ba70bf2947b049The equalizer makes it possible to quickly correct frequency distortions caused, for example, by various kinds of resonances both in the room in which the radio complex is located, and in individual objects in it. ,86e6f450b8cc469628ba70bf2947b049The equalizer has the following technical characteristics: The number of control bands - 6. Medium frequencies of the control bands: in the low frequency range, Hz, 60, 125, 250. In the high frequency range, kHz, 4, 8, 16. Output voltage control limits, dB, ,86e6f450b8cc469628ba70bf2947b049± 10. ,86e6f450b8cc469628ba70bf2947b049Transmission coefficient in the middle position of the regulator sliders, dB - 0. Power supply voltage, V ± 15. ,86e6f450b8cc469628ba70bf2947b049Consumption current (from each of the sources), no more than 50 mA. Dimensions, mm, no more than 200x110x50. ,86e6f450b8cc469628ba70bf2947b049Equalizer weight `` Electronics '', kg, no more than 0.6. ,86e6f450b8cc469628ba70bf2947b049Retail price 25 rubles.,86e6f450b8cc469628ba70bf2947b049,null,ru,null,null,null,null
