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 STEREO VITALIZER opens up a whole new listening dimension by adapting the sound pattern to the non-linearities of the human ear.

The STEREO 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 STEREO 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 (TIGHT) or a punchy, soft and very deep sound character (SOFT). The result is a pleasanter and livelier sound pattern with an unrivalled wealth of detail. The STEREO VITALIZER is especially designed to serve the needs in mastering, cutting and post production work. Used on complete mixes, the STEREO 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 STEREO 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 STEREO VITALIZER!

The housing of the STEREO 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 STEREO VITALIZER should not be installed near units which produce strong magnetic fields or extreme heat. Do not install the STEREO VITALIZER directly above or below power amplifiers or digital processors. If possible, the STEREO 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 STEREO 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.
