In the '80s it was the first to use a different approach to tonal adjustments. In conventional analog equalizers, whether they are shelving, sweepable, graphic or parametric types, various sections of the audio spectra are boosted or attenuated by adding or subtracting bandpasses. In this case, frequency shaping is achieved by summing bandpasses.

During a routine mining expedition in the outer regions of the galaxy five mysterious boxes of unknown origin were found. Rumours among the workers spread quickly that there was a strange feeling being around these boxes, as if time flows in a different way, not just forward but sometimes also folding back on itself. The miners nicknamed them, the five boxes of reverberation. After the excavation process, to study them more closely, it was decided to transport them back to earth.
