The S

TEREO

V

ITALIZER

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

V

ITALIZER

opens up a whole new listening

dimension by adapting the sound pattern to the non-linearities of the

human ear. 

The S

TEREO

V

ITALIZER

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

V

ITALIZER

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

V

ITALIZER

is

especially designed to serve the needs in mastering, cutting and post

production work. Used on complete mixes, the S

TEREO

V

ITALIZER

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

V

ITALIZER

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

V

ITALIZER

!

The housing of the S

TEREO

V

ITALIZER

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

V

ITALIZER

should not be installed near units which

produce strong magnetic fields or extreme heat. Do not install the S

TEREO

V

ITALIZER

directly above or below power amplifiers or digital processors. If

possible, the S

TEREO

V

ITALIZER

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

V

ITALIZER

with a soft, lint-free cloth. Use only stan-

dard cleaning agents. Never use alcohol or paint thinner, because they may

damage the finish.
