Introduction The CLASSIC VITALIZER combines most modern equalisation, phase shift manipulation and harmonic enhancement to provide signal enhancement across the entire audio spectrum. Based on established psychoacoustic and audiometric principles, the VITALIZER brings mid-range material into sharp focus while enhancing high frequencies. The attendant harshness introduced by units that add controlled distortion to the signal is avoided.
Before connecting the VITALIZER or any other equipment turn off all power. Adjust the voltage setting on the back so that it corresponds with the local power conditions. Connections The balanced XLR input connectors are Neutrik XLRs wired pin 2 hot. The unbalanced mono-jacks are wired tip hot. Should the need arise to use the XLR unit in an unbalanced system, pin 3 of both the input and output connectors should be grounded.
Applications Recording Studio 1.The most obvious application of the VITALIZER is to process a final stereo mix, either while mixing or during post-production prior to cutting. It is important to use full-range monitors to assess the effect of any bass processing since it is valuable to occasionally switch the processor in and out of circuit in order to appreciate how much processing has been added.
4. Another interesting application is the use of the VITALIZER right after a compressor unit in the master signal chain. Using the VITALIZER before a compressor can result in more obvious sideeffects of the compressor, such as pumping. It is also possible to patch the VITALIZER into the aux send system of a console in much the same way as a reverb or delay unit as long as the PROCESS SOLO switch is active.
Applications Tape Duplication Tape duplication is often made at high speed, resulting in a deterioration of the high frequency spectrum 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 necessary to modify the bass end as many high speed systems fail to reproduce the bass end of the spectrum faithfully. In both applications, the VITALIZER is both effective and simple to set up.
Both channels of the VITALIZER are set-up identically and can be controlled separately – except the STEREO WIDTH control. If the channels are to be used separately, the STEREO WIDTH control is to be set to OFF. If the VITALIZER is connected to the ,,Aux Send/ Return” Bus, the PROCESS SOLO circuitry must be activated. First Steps Check the PEAK LED regularly: short illuminating indicates peaks at about 3 dB below clipping – constant illumination is to be avoided.
Control Elements Active The ACTIVE-function allows to switch between the processed and unprocessed signal. The green status LED indicates that the channel is active. A relais hard bypass circuitry works on both XLR and Jack connections. In case of a power failure the unit is switched to hard-bypass. Output The outer ring of the dual-concentric control sets the output level and is usually set in its fully clockwise position giving unity gain.
The DEEP button spreads the frequency range around which the SUB BASS is centered. Also the level is increased by +4 dB at the centre frequency of 50 Hz. Control Elements This affects both the hard and soft bass settings giving the choice of four possible permutations.
Control Elements Advancing the setting of the PROCESS DEPTH control simultaneously increases the amount of MID-HI TUNE filter and SUB BASS signals in the mix while attenuating other midrange frequencies to enhance the sense of loudness, thus increasing clarity, bass end punch and overall power.
Working on established inter-channel phase principles, the STEREO WIDTH control increases the subjective soundstage width of any stereo source. The off-centre signals of the stereo source are detected and fed back phase inverted to the opposite channel. This effect can be applied to overall mixes as well as to single instruments. Very interesting is the spreading of the stereo image of overhead mics of drums-sets, choruses or horn sections.
