The CLASSIC VITALIZER combines most modern equalisation, Introduction 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. At the low end the sub-bass is accentuated without incurrin

Before connecting the VITALIZER or any other equipment turn off Connections all power. Adjust the voltage setting on the back so that it corre- sponds with the local power conditions. 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. The following graph shows the correct wiring for connecting unbalanced

1.The most obvious application of the VITALIZER is to process a Applications final stereo mix, either while mixing or during post-production prior to cutting. It is important to use full-range monitors to assess Recording Studio 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. The brain-hearing system soon acclimatises to changes in timbre – processing is easily over- done!

4. Another interesting application is the use of the VITALIZER Applications right after a compressor unit in the master signal chain. Using the VITALIZER before a compressor can result in more obvious side- effects 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. The aux return mixing stages in some consoles are designed in a more cost e

Tape duplication is often made at high speed, resulting in a dete- Applications rioration of the high frequency spectrum of the copies. By proces- sing the output from the source machine, additional brightness can be added to compensate for deficiencies in the copying Tape Duplication system. It may also be necessary to modify the bass end as many high speed systems fail to reproduce the bass end of the spec- trum faithfully. In both applications, the VITALIZER is both effec- tive and simple to

Both channels of the VITALIZER are set-up identically and can be First Steps 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. Check the PEAK LED regularly: short illuminating indicates peaks at about 3 dB below clipping – constant illumination is to be avoided. Please contact SPL if you are not

Control Elements The ACTIVE-function allows to switch between the processed and Active 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 swit- ched 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. However, intensive processing, especially of the ba

The DEEP button spreads the frequency range around which the Control Elements SUB BASS is centered. Also the level is increased by +4 dB at the centre frequency of 50 Hz. This affects both the hard and soft bass settings giving the Deep choice of four possible permutations. Equalising the mid-range signal according to the dynamics and Mid-Hi Tune spectral content of the input signal, the VITALIZER improves the focus of mid-range detail while modifying the overall signal response curve to create

Advancing the setting of the PROCESS DEPTH control simulta- Control Elements neously 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. Because the PROCESS DEPTH control is really varying three parameters at once, it is worthwhile setting aside a little time to explore the important interaction between the PROCESS DEPTH, SUB BASS and MI

Working on established inter-channel phase principles, the Control Elements 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 Surround Processor image of overhead mics of drums-sets, choruses or horn sections. The Surround Proces
