The CLASSIC VITALIZER combines most modern equalisation,
phase shift manipulation and harmonic enhancement to provide
signal enhancement across the entire audio spectrum. Based on
established psychoacoustic and audiometric principles, the
VITALIZER brings mid-range material into sharp focus while
enhancing high frequencies. The attendant harshness introduced
by units that add controlled distortion to the signal is avoided. At
the low end the sub-bass is accentuated without incurring the
penalties of boomyness or clouded low-mid detail that inevitably
occur when conventional equalisers are used. The result is a
sound that is subjectively more powerful, more detailed and
more commercially appealing. Additionally, a separate stereo
width-expander is incorporated which may be used either in
conjunction with the VITALIZER equalisers or on its own.
The VITALIZER may be used on complete mixes or on individual
tracks within a mix. Furthermore, a PROCESS SOLO function allows
the processed signal to be added selectively to different tracks
within a mix using the mixing console’s aux send system. Both
signal channels of the VITALIZER are identical and have separate
controls with the exception of STEREO WIDTH which affects both
channels. If the unit is to be used as two independent mono chan-
nels, this control should be set fully counter-clockwise. The VITA-
LIZER may be connected either via suitable signal insert points or
via the aux send/return circuit of a mixing console; in the latter
application, the PROCESS SOLO button must be active.
The Signal Peak LED should light either briefly on signal peaks
or not at all. In operation, the Signal Peak LED comes on 3 dB
before the onset of clipping in the processing chain. All front
panel push-button switches have status LEDs that light when the
switch is active. Each channel has an independent ACTIVE/BYPASS
switch. Processing is achieved by adding a treated signal to the
original. The treated signal may be auditioned by depressing the
PROCESS SOLO button.
Packaged in a standard 19 " EIA format and occupying 1U
(44,45 mm) of rack space, the VITALIZER can be installed in a stan-
dard rack, but it is recommended to support the rear of the case –
especially in touring applications. The VITALIZER should not be
installed near units which produce strong magnetic fields or
extreme heat or directly above or below power amplifiers or
digital processors. If possible, the VITALIZER should be placed in
an 'analogue rack' where the majority (or all) of the equipment
installed is analogue.
• Use a small, flat bladed screwdriver to set the voltage selector to
the voltage for the area in which the unit will be used.
• Never cover up the ventilation slots on the top side of the unit.
• If, during operation, the sound is interrupted or indicators no
longer illuminate, or if abnormal odour or smoke is detected, or
if liquids are spilled on the unit, immediately disconnect the
power cord plug and contact your dealer.
• Only clean the unit with a soft, lint-free cloth. Use only standard
cleaning agents.
