Radio constructor `` UMNCH-20 '' (20 W low frequency power amplifier).

Radio and electrical constructors, sets.Audio AmplifiersThe radio designer "UMNCH-20" (20 W low-frequency power amplifier) ​​has been produced since 1988 by the Kanevsky plant "Magnit". RC allows you to collect a monophonic PA for amplifying signals from a pre-amplifier or from sources developing an output voltage of the AF 0.25 ... 0.5 V. The reproducible frequency range, with an uneven frequency response - 3 dB - 20 ... 20000 Hz. Rated output power, with a load resistance of 4 ohms - 20 watts. SOI (frequency 1 kHz) no more than 5%. Sensitivity 250 mV. Bipolar power supply +/- 25 V.
