4 TUBE VITALIZER Opera tion safety Dear Customer , Thank you f or the confidence you hav e shown towards SPL electronics GmbH by purchasing the SPL T ube V italizer . 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.
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.
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 .
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.
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.
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.
10 TUBE VITALIZER The Activate P rocess switch switches a relay hard-bypass circuitry for XLR and jack operation. Sets the operating level of the Vitalizer filter network. C ontr ol elements The Activat e Proc ess function switches the T ube Vitalizer´s sound processing section on or off.
11 TUBE VITALIZER Selection of t wo bass timbre (Soft – Tight) and adjusting the intensity V arying bass sounds by balancing Bass and Proc ess Lev el Adding a passive L C filter network to the bass .
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 .
13 TUBE VITALIZER Measurement 2: Bass = Tight Bass-L C filter = A ctive Proc ess Lev el = Max Hi-Mid Freq . = 1 / 1,5 / 2,5 / 3 / 5 / 8 / 14 / 22 kHz Measurement 3: Bass = Soft Bass-L C filter = Off Proc ess Lev el = Max Hi-Mid Freq .
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).
15 TUBE VITALIZER Improv ed high and harmonic frequencies result in a silky top-end with better separa- tion and intelligibility . High Fr eq. Intensity 8 9 High - L C Filt er 10 C ontr ol elements Th.
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.
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).
