2X3 BAND TUBE EQUALIZER 

!

 

POWER SWITCH

 

The unit is switched on with the switch marked POWER. Set the switch 

labeled POWER to the up position if you want to turn on the unit. Set the 

switch labeled POWER to the down position when not in use.   

Due to the tube design of the device, it is advisable to leave a “warm-up 

time” of 15-20 minutes before starting use.   

ATTENTION! the switch labeled POWER puts the device in standby mode, does not 

completely  disconnect  it  from  the  mains,  if  you  want  to  disconnect  the  device 

completely  from  the  mains,  unplug  the  device  from  the  mains  or  switch  o

  the 

main switch at the IEC socket ! 

EQ IN, BYPASS 

In BYPASS mode, the device galvanically connects its outputs and inputs, 

so we can always check the sound of the compression compared to the 

original  signal.  To  select  the  BYPASS  mode,  set  the  switch  to  the  lower 

position. To select the EQ IN mode, set the switch to the upper position. 

TUBE BOOST 

By  using  this  function,  the  gain  of  the  output  tube  ampli

er  can  be 

increased, and the device adding more harmonic distortion to the signal. 

This can makes the resulting sound warmer and more powerful. Set the 

switch to the up position to activate the function. Set the switch to the 

down position if you do not want to use the function.
