Radioconstructor `` Electronics '' (Equalizer).
Radio and electrical constructors, sets.Audio AmplifiersSince 1984, the radio designer "Electronics" (Equalizer) has been producing an experimental plant at the Novosibirsk Research Institute "Vostok". The radio constructor is intended for assembly by radio amateurs of average qualification of a multi-band tone control - equalizer. Such tone controls allow you to obtain a higher fidelity of reproduction of musical programs than usual, allowing you to compensate for the uneven frequency response of the radio complex as a whole, due to one or another of its links. The equalizer also makes it possible to correct frequency distortions caused, for example, by the resonances of the room in which the radio complex is located and individual objects in it. Number of control bands 6. Frequencies of control bands: in the low frequency range 60, 125 and 250 Hz. In the HF region 4, 8, 16 kHz. Output voltage regulation limits ± 10 dB. The transmission coefficient at the middle position of the sliders is 0 dB. Power supply voltage ± 15 V. Consumption current 2x50 mA. Board dimensions 200x110x50 mm. Weight 0.6 kg.
