Advancing the setting of the PROCESS DEPTH control simulta- neously increases the amount of MID-HI TUNE filter and SUB BASS signals in the mix while attenuating other midrange frequencies to enhance the sense of loudness, thus increasing clarity, bass end punch and overall power.
Because the PROCESS DEPTH control is really varying three parameters at once, it is worthwhile setting aside a little time to explore the important interaction between the PROCESS DEPTH, SUB BASS and MID-HI TUNE controls.

This harmonic enhancement circuitry is based on fourth-order filters and phase manipulation, effectively restoring harmonics that have been corrupted during the recording process or by other equipment in the processing chain. It may also be used to increase the subjective brightness of a sound without introdu- cing harshness. Used as an effect, this process is useful for increa- sing the intelligibility and intimacy of vocals.
The harmonic circuitry is driven by a signal combining the original, ”dry” signal and the output signal of the MID-HI TUNE filter. The HARMONICS control determines how much of the restored harmonics are added back to the original signal. Though the circuitry of the VITALIZER is inherently very quite, please note that applying any significant degree of high frequency proces- sing will show up any noise present as part of the signal source. For this reason, the signal source should be as noise-free as possible. The harmonics control is independent of the PROCESS DEPTH control.
