Ex works the unbalanced outputs are set to “Post Fader” state. 

The output level from the unbalanced outputs may be set to –6 / 0 / +6 

dB by means of the dedicated dip switches. This ratios is relative to the 

input signal and fully open volume control. Ex works the gain of the 

unbalanced outputs is set to 0 dB.  

See also page 7 (block diagram) and page 18 (technical Appendix) 

 

THE BALANCED OUTPUTS

 

are situated on the rear panel of PRE 

V630 in the field "ANALOG OUTPUTS " 

and denoted as "RIGHT – BAL - LEFT". 

They are equipped with gold plated XLR 

sockets.   

The balanced outputs always offer 6 dB 

more level than the unbalanced outputs. 

The output level from the balanced 

outputs may be set to -9/-6/-3/0/+3/+6/+9 

dB signal gain. 

This ratios is relative to the input signal 

and fully open volume control. Ex works 

the gain of the balanced outputs is set to 

0 dB.

Attention:  

All other maybe possible dip-switch 

settings should be avoided !
