Radioconstructor-3.

Radio and electrical constructors, sets.Audio AmplifiersRadioconstructor-3 (Two-channel power amplifier) ​​has been produced since 1989. RK is intended for assembling a two-channel power amplifier. The use of integrated circuits in a power amplifier of this category of complexity makes it possible to significantly reduce the number of components and dimensions of the structure. Technical characteristics of the assembled amplifier: The range of reproducible frequencies with a cut-off at the edges of 2 dB - 20 ... 20,000 Hz. Rated output power at a load of 4 ohms and a harmonic distortion of 1.5% - 2x10 W. Maximum output power 2x16 W. The signal-to-noise ratio is no worse than -66 dB. Crosstalk attenuation between channels at a frequency of 1000 Hz -50 dB. The nominal sensitivity of the amplifier at an input impedance of 100 kOhm is about 100 mV. The cost of the set is 32 rubles.
