The S

ITALIZER

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.

-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 L

OW

-position indicates that the input

sensitivity of the S

TEREO

V

ITALIZER

is low, which means high level signals can

be processed at this position. Conversely, the H

IGH

-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 H

IGH

to the L

OW

working level with the proviso that the P

EAK

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 L

OW

to H

IGH

.

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 (+).
