Transistor network electrophone '' Vega-103-stereo ''.
Electric record players and electrophones on semiconductorsDomesticThe network transistor microphone "Vega-103-stereo" has been produced by the Berdsk Radio Plant since 1973. The first-class stereophonic microphone "Vega-103-stereo" (type 1-EF-ZS) is designed for high-quality electro-acoustic reproduction of recordings from mono or stereophonic records of all formats. The Vega-103-stereo electrophone is an upgrade of the Vega-101-stereo model. The model provides for the connection of a tape recorder for recording from a played gramophone record. In addition, the electrophone can be used as an amplifier for AF signals from a tape recorder, a receiver and a radio transmission line. Stereo telephones can be connected to the amplifier output. Nominal output power of each channel at 1% THD is 6 W. The maximum output power of each channel with a THD of 10% is 25 W. The band of reproducible sound frequencies is 63 ... 16000 Hz. Sensitivity from the input of the pickup, receiver and tape recorder 250 mV, radio transmission line 30 V. The limits of tone control ± 8 ... 10 dB. Mismatch of stereo amplification channels in sensitivity and frequency characteristics is not more than 2 dB. The limits for adjusting the stereo balance in each channel are 8 dB. Crosstalk attenuation between stereo channels at frequencies of 200 ... 10000 Hz is not less than 30 dB. The background level along the recording path is not worse than -60 dB. The average sound pressure of each channel is 0.9 Pa. Power supply from the network 127 or 220 V Power consumed from the network at a rated power of 60 W. The dimensions of the microphone are 480x350x180 mm. One speaker - 425x272x234 mm. The weight of an electrophone with two speakers is 30 kg.
