The VITALIZER ACTIVE function switches the STEREO VITALIZER on or off. The
status LED indicates that the S
TEREO VITALIZER has been activated.
The V
ITALIZER ACTIVE function is a relais-hard-bypass function. In the event
of a power failure the S
TEREO VITALIZER is automatically switched to hard-
bypass (power failure safety).
To increase the operational safety of the monitor loudspeakers you
should not switch the S
TEREO VITALIZER on or off at high monitor volume. At
high amplitudes inside the filter, there may be residual charges on the swit-
ching contacts which may be discharged when you switch over. These may
become apparent as audible click sounds. If applicable, reduce or mute the
monitor loudspeakers before switching on or off.
The input stages of the S
TEREO VITALIZER are equipped with PEAK LEDs
which light up around 3 dB before the effect signal path is potentially over-
driven. Make sure that the P
EAK LEDs only light up briefly, if at all. It is
essential to avoid the P
EAK LEDs being lit up for any length of time. If they
do so, reduce the input level or switch from L
OW to HIGH on the rear of the
unit.
The B
ASS control is responsible for the »colour« of the bass sound your
signal is to have. If you move the B
ASS control to the right, you get a drier,
percussive bass sound, known as T
IGHT. As a result of this, on the right-
hand side of the scaling points, there are squares which increase in size, in
line with increased intensity. They symbolize the contoured »T
IGHT« bass
sound.
If the B
ASS control is moved from the centre position (0) to the left, the
bass sound becomes very deep, soft and warm. This sound is known as
S
OFT. This is symbolized with round scaling points which also increase in
size as the intensity increases.
The further the B
ASS control is shifted to the right or left of the centre
position, the more intensive the bass sound in question. However, P
ROCESS
must be positioned to the right of the MIN setting for the bass to be
audible.
You can always hear the original (dry) bass if the B
ASS
control is in a
centre position.
