USE AS A MICROPHONE PREAMPLIFIER 

 

Set  the  input  switch  in  the  Mic  position.  For  proper  calibration  input  gain 
should  be  placed  to  gain  control  at  -20db  and  the  control  Output  in  the 
position indicated by a small arrow where distortion remains below 0.1%. Then 
turn  up  the  gain  control  until  the  signal  has  a  maximum  level,  but  without 
audible  distortion  (which  is  very  evident  in  your  ear  when  present).  Once  the 
Gain  is  set,  if  it´s  necessary,  the  Output  control  can  be  varied  to  modify  the 
output signal. 
 
 

RECORDING ELECTRIC INSTRUMENTS

 (electric guitars, electro-

acoustic, basses, ...)

 

Connect the instrument to the female jacks on the front panel, place the switch 
in the Mic position (not the Line), set the output key in the position indicated by 
a small arrow, and adjust the necessary gain. It is important to have the switch 
in the mic position because in this manner the output will give us a good level 
without raising too much Gain. 
The  +48V  Phantom  Power  is  not  present  in  the  front  jacks  in  any  possible 
combination  of  switches,  to  prevent  damage  to  the  instruments. 
In the case of connecting electric keyboards or sound modules, it is advisable 
to place the switch in the Line position due to their high level output.
