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.

The Red Rock Sound Exciter will allow you to improve and enhance sonic quality of signal more naturally than with equalization. Unlike traditional EQ that just turns up the existing harmonics, Exciter generates additional harmonics, therefore there is no boost in the output signal level, this maintains a clear and balanced sound.
