Special care has gone into the design of the power supply of the Power supply Tube Vitalizer.

The Tube Vitalizer is fitted with both XLR-connectors and TRS Connections stereo jacks for balanced operation, 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 the need arise to use the XLR connectors in an unba- lanced system, pin 3 of the XLRs should be grounded. Inserting a mono jack also unbalances the XLRs. Both

Insert your Tube Vitalizer into the master-inserts of your console or right in between a playback and a recording unit. Recording Studio Application 1: The Tube Vitalizer inserted into the master-inserts of the console. More flexibility is guaranteed when patching the Tube Vitalizer into two sub-groups of the console. Now you have the freed

Tape duplication is often made at high speed resulting in a Tape Duplication 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 Compensating indeficiencies copying system.

When setting up the Tube Vitalizer for the first time, it is wise to First steps approach the controls in a specific order. Use a CD as source. The Tube Vitalizer is designed to process stereo sources. Left and right channels are adjusted with one control. Set-up positions (see front panel picture): Drive to zero (center-position) Bass Sound to zero (center-position) Bass Compression to Off (counter clockwise) Hi-Mid Freq. to 3.5 kHz (center-position) Process Level to zero (counter clockwise)

The Hi-Mid Freq. control is used to set the starting frequency of Control elements a broad-band shelving filter. In line with the setting of Process Level control, all frequencies above this value right through to the Hi-Mid Freq. end of the audio range are processed. 6 The control range of the Hi-Mid Freq. control is between 1kHz (extreme right) and 20kHz (extreme left). In practice, common settings vary between 3.5 kHz and 8 kHz. As the human ear perceives the range between 1 kHz and 3 kHz Set

It also determines the damping intensity of dominant mid frequencies.This allows rapid Process Level adaptation to the loudness curves (Fletcher-Munson curves, 7 ‘curves of equal loudness’, see below). Practical adjustements range between 3 to 7. The human ear perceives the audio frequency spectrum at varying sound pressure levels very differently. Perception

When the tubes are active you can use the Attenuator controls Control elements to reduce the output level for each channel separately. Level changes due to processing can be compensated.
