Y ou hav e decided to use a tool of high per formance which sets you in the position to have fast er success and a better sound quality in your music productions and pre-masterings. A[...]

5 TUBE VITALIZER SPL´s T ube Vitalizer is the top-of-the-line produc t of the Vitalizer range. It is designed for the sound enthusiast in professional recording , mastering and cutting. The effect intensities are opti- mized for this delicate sound proc essing. The T ube Vitalizer combines the finest audio technologies: T ube technology , RC &[...]

6 TUBE VITALIZER The T ube Vitalizer is fitted with both XLR-connectors and TRS stereo jacks for balanced oper ation, though the jacks may be used with unbalanced connections simply by plugging in mono jack-plugs. The level difference that normally occurs when a balanced input or output is used unbalanced is automatically compensated for . Should t[...]

7 TUBE VITALIZER 1 . The most obvious application of the T ube Vitalizer is to proc ess a final mix, either while mixing or during post-produc tion prior to cutting. Insert your T ube Vitalizer into the master-inserts of your console or right in between a playback and a rec ording unit. More flexibility is guaranteed when patching the T ube Vitaliz[...]

8 TUBE VITALIZER 3 . T ape duplication is often made at high speed resulting in a deterioration of the high frequency spec trum of the copies. By processing the output from the source machine , additional brightness can be added to compensate for deficiencies in the copying system. It may also be necessar y to modify the bass end as many high speed[...]

9 When setting up the T ube Vitalizer for the first time , it is wise to approach the controls in a specific order . Use a CD as source. The T ube V italizer is designed to process stereo sourc es. Left and right channels are adjusted with one control. Set-up positions (see front panel pic ture): Drive to z ero (center-position) Bass Sound to zero [...]

12 TUBE VITALIZER The Hi-Mid Freq . control is used to set the star ting frequency of a broad-band shelving filter . In line with the setting of Process Lev el control, all frequencies above this v alue right through to the end of the audio range are processed . The control range of the Hi-Mid Fr eq. control is between 1 kHz (extreme right) and 20 [...]

14 TUBE VITALIZER The Pr ocess Lev el control determines the ratio between Bass and Hi-Mid Freq . to the original signal. It also determines the damping intensity of dominant mid frequencies. This allows rapid adaptation to the loudness cur ves (F letcher-Munson cur ves , ‘ cur ves of equal loudness’ , see below). Pr actical adjustements range [...]

16 TUBE VITALIZER When recording on digital equipment it is essential not to o ver- load the inputs of such systems which results in inv alid samples or digital peaks. The high frequencies can contain transients or sharp s-sounds with high peak levels. The High Comp. works with a soft-k nee characteristic and smoothens these peaks. W e desi- gned t[...]

17 TUBE VITALIZER When the tubes are active you can use the Attenuator controls to reduce the output level f or each channel separately . Level changes due to processing can be compensated . The control characteristic has a very fine resolution before 0 dB (fully clock- wise). The tube output section can be switched into a Limit mode for each chann[...]
