Radio constructor '' Stereophonic amplifier-corrector ''.
Radio and electrical constructors, sets.Audio AmplifiersThe radio constructor "Stereophonic amplifier-corrector" has been produced since the beginning of 1986. The radio constructor allows you to assemble a correcting amplifier for the electromagnetic head of an electric player or an electrophone. The need to use such an amplifier is due to the fact that it is necessary to compensate for the rise at higher frequencies obtained in the process of recording a program on a record and to somewhat reduce the frequency distortions introduced by the electromagnetic head. The frequency range of the amplifier-corrector is 20 ... 20,000 Hz. Signal-to-noise ratio 68 dB. Harmonic distortion 0.05%. Input impedance 300 kOhm. Load resistance 10 kOhm. Dimensions of the assembled board - 105x130x55 mm. Its weight is 150 gr.
