The "Electronics B1-01" electronic device has been manufactured by the Kazan Radio Components Plant since 1975. The high-end stereo electronic system "Electronics B1-01" consists of four separate functional units: a stereo electric player, a stereo audio frequency amplifier and two loudspeakers. A three-speed (45, 33, 16 rpm) top-class "0-ЭПУ-1С" electroplay device is used in the electric player block. Knock factor 0.2%. The speeds in the EDC are switched by a pushbutton switch that changes the frequency of the generator voltage. A low-speed capacitor synchronous electric motor of the type "TSK-1" was used as an electric motor. The player has a metallic tubular tonearm statically balanced in all planes. The EPU has a roll force compensator, a microlift and a device for controlling the weight of 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 EDA is not already 20..20000 Hz. The high-quality two-channel stereo amplifier of the model is designed to work with various sources of sound programs. Its rated output power in each channel is 60 watts. The nonlinear distortion factor of 0.5%. The bass amplifier is provided with stereo balance adjustment, separate adjustment of the bass and treble frequencies. There is a possibility to connect simultaneously two speakers in each channel. The stereo amplifier has a separate indication of the output signal level in each channel by arrow indicators, light signaling of the amplifier overload, the presence of filters for the high and low frequencies, the device for detuning the loudspeaker and separate loudspeakers The model uses closed-type speakers with a volume of 54 liters, each of which consists of two 10GD-30 loudspeakers and four ZGD-31 loudspeakers. The dimensions of the electric player 170x465x385 mm, low-frequency amplifier 490x300x110 mm, one speaker system 630x340x250 mm.The weight of individual devices is 15, 20 and 30 kg, respectively.
