Today's sound system market is so much diverse that an average buyer finds itself difficult to make choice as to suitable home sound system. So called "active" speakers could be just distinguished from such variety, since the principles of their work and sound have some similarity to the Slonov Sound Design's systems.
"Active" speakers stand out against general "grey" acoustic background due to integration of power amplifiers – one amplifier to each loudspeaker speakers, an active band pass filter that assigns a signal band to each loudspeaker is integrated into each amplifier. Thus, a well-known principle in electrical engineering of signal "active filtering" is realized, when an original signal is divided by bands at the beginning and then it is amplified with separate amplifier for each band. This principle allows rejecting traditional passive filters embedded in the speakers, which affect negatively the overall system sounding. The work of passive filter could be compared with a blender, which transforms the signals received into sound "mixture". All of us like tomatoes, cucumbers and onion cut in pieces in the salad, but nobody will come across to cut them in a blender and to serve in the form of unappetizing slush! Similar to that we may observe with a sound signal in the speakers with passive filters.
Notwithstanding all the pluses of the "active filtering" principle applied in so-called "active" speakers, realization of this principle is waning because of several reasons. First of all, placement of the amplifiers with embedded active filter inside of the speakers results in so-termed "microphone effect", when a loudspeaker's reverse wave inside of the body impacts on the amplifier and filter elements creating distortions, which are transferred to a loudspeaker and impact again on the amplifier. Such back action tinges system sound extremely negatively. Secondly, all the lovers of qualitative sound are aware of the fact that good power amplifier exceeds often size and weight of the speaker to which it is connected. Moreover, when three amplifiers are needed (in case of 3-band system), it is hardly to imagine how they can be allocated inside of the speaker. Thirdly, active filter integrated into an amplifier cannot be retuned, if necessary.
Therefore, the Slonov Sound Design offers the most comprehensive and coherent approach to active filtering, when an independent device is used for signal processing – digital active band pass filter (a crossover), which takes separate place in the sound system the same as the frequency amplifiers. same as the ate place is used for allocated inside of er are placed inside of the nets have been realisedAs As we can see on the audio signal distribution scheme below, it takes a separate place between the signal source (CD transport) and the power amplifiers for high, medium and low frequencies. Due to broad spread of digital data carriers, application of digital crossover is of particular importance, since band-division signal in digital format provides additional advantages and allows elevating the level of sound quality to the early unreachable level. Such allocation of active band pass filter allows tuning the entire system accurately to maximum under individual specifics of the room where the sound system will be placed.
Active filtering allows reducing drastically:
– Signal phase distortions;
– Dynamic range compression;
– Interference of different-range frequencies.
All these factors affect sound reproduction negatively. When the level of their impact is reduced, a listener will be capable to sense high detail and clarity of sound, to feel deeply a soundstage and to enjoy accuracy of acoustic images. High audio quality of the sound systems is ensured with their design peculiarities described in Section "Systems". At the same time, it is worth to mention that sound systems offered by the Slonov Sound Design are developed specifically to be used with active filtering. They are impossible to be used in traditional scheme with one power amplifier! Therefore, the Slonov Sound Design formulates the priority objective for the project to provide a set of the servicesе. This set of services includes the following:
– Sound system designing;
– Selection of appropriate electronic components;
– Final installation and tuning.
Therefore, you receive not simply the sound systems made to order, but a SOUND MADE TO ORDER!
Individual approach to creation of each system ensures complete conformity to the client's expectations.
