STEREO
The STEREO VITALIZER is an equalizer concept which makes use of scientific
psychoacoustic technology to process audio signals. The unique combina-
tion of dynamic equalizers, amplitude-controlled phase correction and
harmonic filtering in the S
TEREO VITALIZER opens up a whole new listening
dimension by adapting the sound pattern to the non-linearities of the
human ear.
The S
TEREO VITALIZER gives the mid frequencies accurate transparency
with a soft, unobtrusive sound. The treble and harmonics range is
reworked with broadband shelving filters, which focus on achieving a
smooth, silky sound pattern. High frequencies are livened up without them
sounding hard or agressive. The S
TEREO VITALIZER uses a newly developed
filter network to process the low frequency range. The bass is accentuated
without any risk of emphasizing the lower mid frequencies unnaturally.
You can choose between a dry, percussive bass (T
IGHT) or a punchy, soft and
very deep sound character (S
OFT). The result is a pleasanter and livelier
sound pattern with an unrivalled wealth of detail. The S
TEREO VITALIZER is
especially designed to serve the needs in mastering, cutting and post
production work. Used on complete mixes, the S
TEREO VITALIZER will perform
the same task as those esoteric and costly equalizers often used for audio
sweetening but with far greater tonal flexibility and at a much lower cost.
The S
TEREO VITALIZER may also be teamed up with a single-ended noise
reduction system to provide the ultimate, low-cost post production clean-
up system for treating old masters which are often tonally dull as well as
noisy. You will be amazed by how transparent and powerful almost every
audio signal sounds after it has been processed with the S
TEREO VITALIZER!
The housing of the S
TEREO VITALIZER has the standard 19" EIA format and
occupies 1 unit (1 U = 44 mm) in your rack. When installing the unit in a
19"-rack, the rear side of the unit needs some support, especially in a
touring case. The S
TEREO VITALIZER should not be installed near units which
produce strong magnetic fields or extreme heat. Do not install the S
TEREO
VITALIZER directly above or below power amplifiers or digital processors. If
possible, the S
TEREO VITALIZER should be placed in an »analog rack« where
the majority of (or all) the equipment installed is analog. This eliminates
problems which could result from interfering high-frequency signals such as
clock frequencies, MIDI or SMPTE control signals.
Check that the voltage details quoted on the back panel are the same as
your local mains electricity supply (Model 9320 only). Use a minus (-)
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 of the
unit. If, during operation, the sound is interrupted or indicators no longer
illuminate, or if abnormal odor or smoke is detected, or if water is spilled
on the unit, immediately disconnect the power cord plug and contact your
dealer or Authorized Service Center.
Only clean your S
TEREO VITALIZER with a soft, lint-free cloth. Use only stan-
dard cleaning agents. Never use alcohol or paint thinner, because they may
damage the finish.
