Transistor network electrophones '' Rondo-203 '' and '' Rondo-204-stereo ''.
Electric record players and electrophones on semiconductorsDomesticElectrophones "Rondo-203" and "Rondo-204-stereo" from the 1st quarter of 1979 were produced by the Kazan Electrotechnical Plant. Stereophonic electrophone "Rondo-204-stereo" is intended for reproduction of records from mono and stereo phonograph records. The microphone can also be used as an amplifier for signals from external sources. A three-speed EPU type IIEPU-62SP with a piezoceramic pickup is installed in the electrophone. The microphone uses two АС 8АС-4, each of which has two 4GD-35 heads. The maximum output power of the electrophone is 2x10 W. The nominal range of reproducible sound frequencies in terms of sound pressure is 80 ... 12000 Hz. Harmonic distortion 1.5%. Tone control range ± 10 dB. Power consumption does not exceed 60 W. The dimensions of the microphone are 458x322x164 mm. Weight 22 kg. The price is 170 rubles. A small series of monophonic electrophones "Rondo-203" was released with the same design as the "Rondo-204-stereo" electrophone, but differing in one speaker, one channel of a low-frequency amplifier, the absence of a mono-stereo switch and a stereo balance control, the presence of the "Intimacy "and some other changes.
