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.

In this case, frequency shaping is achieved by summing bandpasses.
