The UMNCH-20 radio designer (20 W low-frequency power amplifier) "u200b"u200bhas been producing the Kanev Magnit factory since 1988.
RK allows you to collect a monophonic PA for amplifying signals from a pre-amplifier or from sources developing an output voltage of the RF of 0.25 ... 0.5 V. The range of reproduced frequencies, with frequency response uneven - 3 dB - 20 ... 20,000 Hz.
Rated output power, with a load resistance of 4 ohms - 20 watts.
THD (frequency 1 kHz) no more than 5%.
Sensitivity 250 mV.
Power supply bipolar / - 25 V.
