Transistor network electrophone '' Arctur-003-stereo ''.
Electric record players and electrophones on semiconductorsDomesticThe network transistor microphone "Arctur-003 stereo" has been producing the Berdsk radio plant since the 1st quarter of 1977. The stereophonic electrophone of the highest complexity group "Arctur-003-stereo" is intended for reproduction of records from mono or stereo gramophone records with disc rotation frequencies of 33 and 45 rpm. The Arctur-003 stereo electrophone is developed on the basis of the Arctur-001-stereo serial amplifier-switching device. In addition to the volume and tone controls for low and high frequencies, the microphone has switchable low and high frequency filters with which you can narrow, expand and highlight the reproducible frequency band, an active `` presence '' filter, as well as arrow indicators of the output levels of both amplifiers stereo channels. The new electrophone uses EPU G-600 V (PNR) or another similar one with a magnetic pickup head. The rotational speed of the disk is set by the built-in stroboscope. The microphone is equipped with two 25AC-2 three-way loudspeakers. The nominal range of reproducible frequencies for sound pressure is 40 ... 20,000 Hz. Sinusoidal rated output power 25 W. Background voltage level at sinusoidal output power -50 dB. The detonation coefficient of the EPU is ± 0.1%. Power consumption from the mains is 150 watts. Dimensions of the electric player 615x385x200 mm, one speaker - 480x285x250 mm. The mass of an electric player with a bass amplifier is 22 kg.
