STEREO

The control

The VITALIZER ACTIVE function switches the STEREO VITALIZER on or off. The

status LED indicates that the STEREO VITALIZER has been activated.

The VITALIZER ACTIVE function is a relais-hard-bypass function. In the event

of a power failure the STEREO VITALIZER is automatically switched to hard-

bypass (power failure safety).

To increase the operational safety of the monitor loudspeakers you

should not switch the STEREO 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 STEREO 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 PEAK LEDs only light up briefly, if at all. It is

essential to avoid the PEAK LEDs being lit up for any length of time. If they

do so, reduce the input level or switch from LOW to HIGH on the rear of the

unit.

The BASS control is responsible for the »colour« of the bass sound your

signal is to have. If you move the BASS control to the right, you get a drier,

percussive bass sound, known as TIGHT. 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 »TIGHT« bass

sound.

If the BASS 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

SOFT. This is symbolized with round scaling points which also increase in

size as the intensity increases.

The further the BASS control is shifted to the right or left of the centre

position, the more intensive the bass sound in question. However, PROCESS

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 BASS control is in a

centre position.
