The control

elements of the

S

TEREO

V

ITALIZER

®

The V

ITALIZER

A

CTIVE

function switches the S

TEREO

V

ITALIZER

on or off. The

status LED indicates that the S

TEREO

V

ITALIZER

has been activated. 

The V

ITALIZER

A

CTIVE

function is a relais-hard-bypass function. In the event

of a power failure the S

TEREO

V

ITALIZER

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

V

ITALIZER

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

V

ITALIZER

are equipped with P

EAK

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 H

IGH

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.
