Warranty ....................14 Foreword Dear customer, thank you for the confidence you have shown towards SPL elec- tronics GmbH by purchasing the SPL Stereo Vitalizer Jack, one of the most powerful and creative signal processors currently avai- lable. The Stereo Vitalizer Jack is a first-rate sound processor with exemplary performance, unrivalled sound quality and excellent workmanship.
The Stereo Vitalizer Jack is built to the same high manufacturing standards as all SPL units, using 1% metal film resistors, MKT capa- citors and a toroidal transformer. The control topography has been streamlined to give easy access to the Vitalizer functions without compromising on flexibility or audio quality, freeing the engineer to be creative.
The Stereo Vitalizer Jack is equipped with unbalanced inputs Connections and outputs. The connection can either be made with mono jacks or gold-plated RCA connectors. The output is split to both connectors, so that you can record on two media simultaneously. Make sure to connect only one input signal to either the RCA or the jack connector.

Applications When patching the Stereo Vitalizer Jack into the sub-groups or master-breaks of the console, note if the master breaks are swit- ched »pre« or »post« fader. They should best be switched »pre« fader, so that a variation of the master fader does not affect the input level of the Stereo Vitalizer Jack.
"You try to find a balance between two center mics then balance that with whatever you´re using from left-right pair. We then treated it with the SPL VITALIZER, a psychoacoustic equalizer. It brings a lot more presence to the upper end of the spec- trum and a very deep low end so that the voice sounds full.”...
First steps When setting up the Stereo Vitalizer Jack for the first time, it is wise to approach the controls in a specific order to avoid confu- sion and to achieve positive results right from the start. Use a CD as source.
Control Elements Active The Active function switches the Stereo Vitalizer Jack on or off. It is a relay-hard-bypass function that works on both RCA and Jack connections. In the event of a power failure the Stereo Vitalizer Jack is automatically switched to hard-bypass (power failure safety).
Control Elements The Mid-Hi Tune control is used to set the starting frequency of a broad-band shelving filter. In line with the setting of Process control, all frequencies above this value right through to the end of the audio range are processed. Mid-Hi Tune The control range of the Mid-Hi Tune control is between 1 kHz (extreme right) and 20 kHz (extreme left).
For the human ear, the sound is more pleasant and easier to Control Elements perceive than the original. In other words, increasing the Process value also increases the intensity of the Mid-Hi Tune filter and the Bass filter, whilst dominant mid frequencies are damped by amplitude-controlled phase shiftings.
Control Elements The Stereo Expander potentiometer controls the width of the stereo image. Working on estabilshed inter-channel phase princi- ples, the Stereo Expander control is be used to increase the subjective soundstage width of any stereo source. The off-center Stereo signals of the stereo source are detected and fed back to the opposite channel phase inverted.
The specific period of this limited warranty shall be that which is described to the original retail purchaser by the authorized SPL dealer or distributor at the time of purchase. SPL does not warrant its products against any and all defects:...
