The frequency spectrum is usually divided into three frequency bands: highs, mids and lows, all of which are provided in the Vitalizer, even though, as opposed to conventional usage, low and mid filter settings are interrelated. The high frequency control allows processing of high frequencies and harmonics. You can adjust each of the three frequency bands separately and control the intensity of the process independently.

The low and mid filters share the same intensity control. The fact that you can set the filters and the intensity independently allows for many sound possibilities with only two controls: when processing low signals you can choose between a deep, soft or dry sound. In conjunction with the intensity control, strong amplification of low frequencies with a low intensity setting results in a totally different sound than if you were to have low amplification with high intensity. The connection to the mid filter is always given by the intensity control. This means that you can optimize low and mid frequencies jointly for the sake of psychoacoustic and audiometric relevance. For example, the mid frequency band, to which the human hearing is specially sensitive, can be automatically damped when you choose a SOFT setting.
