The amplifier amplifier "Romance 50RU-122S" was produced since 1991 by the Kharkov Taras Shevchenko PSZ. A pseudo-sensory tuner amplifier of the 1st complexity group is designed to receive and amplify monophonic and stereo programs in the VHF band, high-quality amplification of stereophonic music phonograms from various sources with the possibility of improving the quality of the phonogram using an equalizer. Technical characteristics: Tuner: The frequency range of 65.8 ... 74.0 MHz. Sensitivity at a signal-to-noise ratio of 36 dB is not worse than 3 µV. 50 dB mirror channel selectivity. The separation of stereo channels at a frequency of 1000 Hz is at least 30 dB. The range of reproducible frequencies for electrical voltage is 31.5 ... 18000 Hz. Amplifier: Rated output power at a load of 8 ohms - 2x25 watts. The range of effectively reproduced frequencies is 20 ... 20000 Hz. The harmonic coefficient at a frequency of 1000 Hz is not more than 0.4%. Maximum output power 2x35 watts.
