STEREO
Before connecting the STEREO VITALIZER switch the power off at all
connected units.
The STEREO VITALIZER is available in two version up to autumn 1995:
Version 1: unbalanced jack version (mono-1/4“ jacks wired tip hot)
Version 2: professional version with unbalanced (switching mono-
1/4“jacks wired tip hot) and electronically balanced
(3-pole XLR wired pin 2 hot) connectors. (Unbalanced
connections are preferred; XLR´s may remain connected)
From autumn 1995 only version 2 will be available.
Insert your STEREO VITALIZER into the Master-Inserts or Sub-Groups
Inserts of the console!
Never connet the STEREO VITALIZER between console and amplifier! Each
fader movement will result in a tonal change of the STEREO VITALIZER-effect,
as the input sensitivity is varied. Furthermore, impedance problems might
cause additional noise.
A switch on the rear panel sets the input operating level for both chan-
nels. Two positions are available: The LOW-position indicates that the input
sensitivity of the STEREO VITALIZER is low, which means high level signals can
be processed at this position. Conversely, the HIGH-position is used for low
level signals, as the input sensitity is high.
The unit may be run hotter if desired by switching the level setting from
the HIGH to the LOW working level with the proviso that the PEAK LEDs on
the front panel are not regularly flashing. This will achieve processing at a
lower input sensitivity and will result in a more intensely processed sound.
Conversely, in order to achieve milder processing, the switch may be set
from LOW to HIGH.
Should the need arise to use the XLR connectors in an unbalanced
system, pin 3 of both the input and output connectors should be grounded.
Note that unbalancing the output in this way will cause a level increase of
6dB. Follow the diagram below:
The Pin assignment of the XLR-connectors is Pin 2 = hot (+).
