Electronic musical instrumentsProfessionalThe electronic button accordion "Estradin-8B" has been produced since 1971 by the Zhytomyr plant "Elektroizmeritel". The button accordion is built on the basis of a conventional mechanical button accordion, which has 61 keys and 120 buttons for bass and ready chords. The button accordion, which retains its reed resonators, is electrically connected to the electronic unit and acoustic units. Preserving the property of an ordinary button accordion allows you to preserve the technique of playing on it and use the appropriate musical literature for teaching and performing works of various genres. In addition, alternating and combined sounding of electronic and normal voices is possible. Registers, timbres, the nature of the amplitude envelope of the sound and other effects are located on the electronic unit, and some of the most frequently used controls are located directly on the button accordion. The button accordion has: a range of fundamental tones of 6,3 octaves (from F counter-octave to G of the fourth octave); 5 octave registers in the right keyboard and 3 registers in the left; frequency vibrato, adjustable in depth and frequency; musical effects - tremolo, glissando, drums, reverb, attack control, tutti organ; output power 25 W. The dimensions of the electronic unit are 830x500x250 mm. Two acoustic units of the accordion contain four loudspeakers of the 4GD-28 type each. The price of the set is 1400 rubles. Over the years of production, there have been two modernizations of the unit and acoustic units.
