Electrophone '' Electronics B1-01 ''.
Electric record players and electrophones on semiconductorsDomesticElectrophone "Elektronika B1-01" has been producing the Kazan plant of radio components since 1975. The top-class stereophonic electrophone "Elektronika B1-01" consists of four separate functional blocks: a stereophonic electric player, a stereo audio frequency amplifier and two acoustic speakers. A three-speed (45, 33, 16 rpm) top-class "0-EPU-1S" electro-playing device is used in the block of the electric player. Knock coefficient 0.2%. The speeds in the EPU are switched by a push-button switch that changes the frequency of the generator voltage. A low-speed condenser synchronous electric motor of the "TSK-1" type was used as an electric motor. The turntable has a metal tubular tonearm, statically balanced in all planes. The EPU has a shearing force compensator, a microlift and a device for adjusting the weight brought to the end of the needle. The tonearm is equipped with a GZM-003 magnetoelectric head operating at a reduced weight of 20 mN. The operating frequency range of the EPU is not more than 20..20000 Hz. The high-quality two-channel stereo amplifier of the model is designed to work together with various sources of sound programs. Its rated output power in each channel is 60 W. Nonlinear distortion factor 0.5%. The bass amplifier provides for stereo balance adjustment, separate adjustment of the bass and treble timbre. It is possible to connect two speakers at the same time in each channel. The stereo amplifier has a separate indication of the output signal level in each channel with arrow indicators, a light signaling of the amplifier overload, the presence of filters for high and low frequencies, a device for turning off loudness and separate turning off of the speaker. The model uses closed-type speakers with a volume of 54 liters, each of which consists of two loudspeakers 10GD-30 and four ZGD-31. The dimensions of an electric player are 170x465x385 mm, a low-frequency amplifier is 490x300x110 mm, and one speaker system is 630x340x250 mm. The mass of individual devices is, respectively, 15, 20 and 30 kg.
