The new Stereo Vitalizer Jack, model 9736, is an entirely re-desi-

gned and improved version of the successful predecessor, model
9319.

The Stereo Vitalizer Jack is an equaliser concept which makes

use of audiometric technology to process audio signals. The
unique combination of dynamic equalisers, amplitude-controlled
phase correction, harmonic filtering and stereo expanding opens
up a whole new listening dimension by adapting the sound
pattern to the non-linearities of the human ear.

The new Stereo Vitalizer Jack represents the entry level of the

Vitalizer product range, but utilises the same principles as
employed in the more professional models. It is the ideal choice in
cost-conscious situations for processing stereo signals, for
example in project studios, audio edit suites and small sound
reinforcement systems.

The Stereo Vitalizer Jack is built to the same high manufacturing

standards as all SPL units, using 1% metal film resistors, MKT capa-
citors and a toroidal transformer. The control topography has
been streamlined to give easy access to the Vitalizer functions
without compromising on flexibility or audio quality, freeing the
engineer to be creative.

The design is optimised for ease and speed of use with one set

of controls handling both channels; this approach also ensures
both channels are processed identically.

Already the predecessor of the new Stereo Vitalizer Jack was

awarded the 'Stage Design Award' in 1994 by the 'Artist' maga-
zine for successful use in live applications.

The housing of the Stereo Vitalizer Jack has the standard 19" EIA

format and occupies 1U (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 Stereo Vitalizer Jack should not be
installed near units which produce strong magnetic fields or
extreme heat. Do not install the unit directly above or below
power amplifiers or digital processors. If possible, the Stereo
Vitalizer Jack should be placed in an “analogue rack” where the
majority of (or all) the equipment installed is analogue. This elimi-
nates problems which could result from interfering high-
frequency signals such as clock frequencies, MIDI or SMPTE
control signals. If, during operation, the sound is interrupted or
indicators no longer illuminate, or if abnormal odor or smoke is
detected, or if liquids are spilled on the unit, immediately
disconnect the power cord plug and contact your dealer.

Only clean your Stereo Vitalizer Jack with a soft, lint-free cloth.

Use only standard cleaning agents. Never use alcohol or paint
thinner, because they damage the finish. Before connecting the
Stereo Vitalizer Jack switch the power off at all connected units.
