DRIVE

 

– 

this knob controls the level of the signal 

entering the saturation circuit. Increasing the DRIVE 
level results in stronger signal saturation, giving the 
ear friendly distortion and audibly higher RMS level, 
thus loudness. Note that the saturation level depends 
also on the input signal level.

ON/OFF

 

– 

Turns the saturation module on and off. 

With the saturation module engaged the  DRIVE and OUTPUT 
knobs are inactive.

LED  METER

 

– 

indicates  the  amount  of  added 

harmonics 

– 

the  depth  of  saturation.  The  orange  LED 

lights on above the 4% THD, red LED lights on above the 8% 
THD.  Above  8%  THD  the  signal  saturation  is  clearly 
audible.

OUTPUT

 

– 

this knob controls the level of the signal 

leaving the saturation circuit. In position 0 the signal 
is muted.

LCR

 

– 

this switch sets signal panning.

L- left channel

;

 C - central - mono

;

 R 

– 

right channel.

The LCR switch acts independently from the saturation 
module and is active even when the latter is disengaged.

1-8 - ON/OFF

 

– 

this switch turns on and off all the 

8  saturation  channels  simultaneously.  In  the  OFF 
position the LED flashes red.

MIX  -  MAGIC/NORMAL

 

this  switch  activates  the   

MAGIC

” 

module.  In  NORMAL  position  the  module  is 

inactive and does not influence the mixed signal.

MONITOR

 

– 

this knob controls the signal level on 

the monitor output.

MAIN 

– 

this knob controls the signal level on the 

main output. The main output level is indicated by two VU 
meters.
