Both channels of the VITALIZER are set-up identically and can be
controlled separately – except the STEREO WIDTH control. If the
channels are to be used separately, the STEREO WIDTH control is
to be set to OFF. If the VITALIZER is connected to the ,,Aux Send/
Return”Bus,the PROCESS SOLO circuitry must be activated.
Check the PEAK LED regularly: short illuminating indicates
peaks at about 3 dB below clipping – constant illumination is to
be avoided. Please contact SPL if you are not satisfied with the
Input Level adjustment.All front switch positions are indicated by
Status-LEDs.The ACTIVE button switches each channel in or off.
When setting up the VITALIZER for the first time, it is recom-
mended to approach the controls in a specific order to achieve
positive results right from the start.
Initially, set the SUB BASS and HARMONICS controls to 0.Please
note that the SUB BASS control is off in its center position, not
when set fully counter-clockwise.
Set the MID-HI TUNE control to around 3.5 kHz and then
advance the PROCESS DEPTH control until the processing can be
heard.You should hear a change in the mid-range but no appre-
ciable change at the bass end.
To hear the effect of the MID-HI TUNE control in isolation, in-
crease the PROCESS DEPTH and set the SUB BASS and HARMONICS
controls to 0.
Next, try advancing the SUB BASS control both clockwise and
counter-clockwise and listen to the different effect on the
character of the bass end.At this point,it is also interesting to hear
the difference the DEEP button makes (full-range monitors
needed; near-field monitors do not generally have the necessary
low frequency capability to reveal the extent of the low-
frequency processing applied by the VITALIZER).
To hear the effect of the SUB BASS in isolation, turn up the
PROCESS DEPTH control,set HARMONICS to minimum and set the
MID-HI TUNE fully counter clockwise to its maximum frequency of
22 kHz.
In the next step, advance the HARMONICS control and listen to
the high end details.To hear the effect of this control in isolation,
set the PROCESS DEPTH to minimum. Note that the MID-HI TUNE
frequency control still influences the action of the HARMONICS
section.
Finally, turn up the STEREO WIDTH control to the 12 o’clock
position and note the soft spreading stereo image.
