Stereophonic transistorized electrophone "Arctur-005-stereo".

Electric record players and electrophones on semiconductorsDomesticSince 1983, the Arctur-005S stereophonic transistor microphone has been producing the Berdsk Radio Plant. The EF consists of an "Arctur EP-005S" type electric player, an "Arctur UKU-005S" amplifier and two 50-watt acoustic systems. The EF has: an electronic indicator of the output signal with overload, an indicator of the inclusion of frequency filters, indicators of inputs, an indication of the operation of protection against short circuit of acoustic systems. The low-frequency amplifier of the electrophone has a switchable loudness compensation, operational attenuation of the volume, acoustic control, outputs of the main and additional speakers, discrete volume control. UCU case is metal, EP is polystyrene, speaker case is made of wood. The blocks are silver colored. The operating frequency range of sound is 20 ... 20,000 Hz. Harmonic distortion 0.3%. Knock coefficient 0.1%. The rated output power of the UKU is 2x35, the maximum is 2x50 W. The rumble level is -66 dB. EP dimensions - 430x360x140 mm. UKU - 430x360x70 mm. The total weight of the microphone is 24 kg.
