The DEEP button spreads the frequency range around which the SUB BASS is centered. Also the level is increased by +4 dB at the centre frequency of 50 Hz.

This affects both the hard and soft bass settings giving the choice of four possible permutations.

Equalising the mid-range signal according to the dynamics and spectral content of the input signal, the VITALIZER improves the focus of mid-range detail while modifying the overall signal response curve to create an impression of increased loudness. The degree of processing is controlled by the PROCESS DEPTH control while the MID-HI TUNE control is used to set the lower frequency limit at which processing will take place.

With the control set fully counter-clockwise at 22 kHz, no audible processing will be evident as the filters are limiting processing to those frequencies outside the human range of hearing. However, if you turn the PROCESS DEPTH control fully clockwise you will hear the high end starting to sound duller than the dry signal. This effect can be used to dull out very bright signals. By decreasing the frequency setting, the processing will become more evident. Additionally, the lower the frequency is set, the more obvious the effect becomes since more of the audio spectrum is being treated.

It is generally best to start off with this control set to some- where between 3 kHz and 6 kHz and then fine tune by ear.

Adjusting the bandwidth preset control (”Q”, inside the front panel) changes the characteristics of the MID-HI TUNE filter. The VITALIZER is shipped with the Q setting in its minimum position (counter-clockwise) which is best suited to general purpose processing. A higher Q may be selected in order to selectively enhance certain parts of the audio spectrum such as hi-hats as may be desirable when mastering a record or reworking an existing recording.

If the Q control is advanced too far clockwise, the filter is likely to oscillate. In this case the control should be backed off until oscillation ceases. For stereo applications, care should be taken to ensure that the Q presets on either channel are set up as similarly as possible to eliminate the possibility of spectrally related image shifts.

This control affects the amount of SUB BASS and MID-HI TUNE filter signal added back into the mix and will cause certain domi- nating mid-range frequencies to be attenuated increasing the overall sense of loudness. Since the human ear perceives the audio spectrum differently at different SPLs (sound pressure levels), the VITALIZER reshapes the spectrum so as to convince the human brain/hearing system that the sound being heard is louder than it actually is.
