Sound audiocomplex

I take out on court of readers the sound complex developed and made by me, the sound audiocomplex is more exact.

I Will begin the story from far away and with some explanations. To be engaged in radio equipment designing I began in the mid-sixties the last century. In the early seventies in the city of Borisov the Berezina restaurant was constructed comfortable, for those times. The professional vocal and tool ensemble worked at this restaurant. And so this ensemble worked at radio equipment which was made completely by me. For those times it was difficult to acquire qualitative radio equipment: amplifiers, stereo speakers etc. The lamp sound intensifying equipment made by me for those times worked nearly 24 hours per day and the main thing - smoothly. Since those far times I pursued the aim to create the sound equipment, allowing to cause in the listener effect of complete presence on speech of the musical performer. Since then I assembled more than 100 amplifiers of low frequency of various capacity and complexity from 1 W to 300 W, on various element bases, from lamps and transistors to devices completely on chips. It was possible to gain at reproduction of qualitative stereophonic soundtracks effect of volume and high-quality sounding, but no more. Once in 1999, being present at a concert of VIA of "Pesnyara", I came to the unexpected solution of this problem. Instead of whether to create to me sound equipment on a method of vocal and tool ensemble? That is voice equipment separately, and for tools separately. I will not describe, how many I had to work at an embodiment of this idea in life. The large quantity of special literature on this subject was re-read, the set of experiments is put. In 2000 I reached to what aspired. On sound audio a complex consisting of six amplifiers of low frequency and eight stereo speakers, I virtually was present at concerts of "Beatles", "Pesnyara" etc. Me not expensive intensifying equipment, allowing to gain effect of complete presence of the listener on execution of a piece of music at reproduction of qualitatively written down stereophonic soundtracks is developed. Invited by me on listening musical experts all unanimously declared that live execution practically does not differ from execution on a soundtrack, I emphasize especially once again, qualitatively written down stereophonic soundtrack.

Equipment for reproduction of soundtracks was used by p the following: the bobinny tape recorder "Aster of 106 stereos" of the first class, player of vinyl disks of the highest class "Radio engineering", player for playing of audio of the disks "Thomson", computer 52nd high-speed CD ROM. Co all this equipment of the reproduction, the amplifiers developed in my execution, were coordinated in the best way. The block diagram of an audiocomplex is provided on fig. 1. Six amplifiers were объедены in two cases. In one case the voice stereophonic amplifier of high-quality reproduction (fig. 2), with deep adjustment of the frequency characteristic on high and low frequencies and the divided adjustment of strengthening on each channel.

Loudspeakers are located p from the floor plane at height of 2,5 meters. Brands of loudspeakers are presented in tab. 1.
