CONNECTION TO THE MAINS 

 

The 

Unico 150

  is set at the factory to the appropriate mains voltage of the 

country it will be shipped to.  

 

IMPORTANT! The voltage setting may not be changed by the user. 

Never  connect  the 

Unico  150

  to  AC  mains  if  the  local  voltage doesn’t 

match the value indicated on the rear panel!   

The  mains  fuse  is  located  in  the  fuse-holder  integrated  in  the  IEC  mains 

socket and inside the amplifier.

  

 

IMPORTANT!  Always replace fuses with new ones of the same type 

and value.

OPERATION 

 

SWITCHING ON AND WARM-UP 

 

WARNING!  Only  s

witch  on  the 

Unico  150

  after  all  the 

connections have been made and checked. 

 

Before switching on, ensure that the volume control is at zero (fully 

anti-clockwise),  and  allow  it  to  remain  in  that  position  until  the 

initial automatic start-up phase is complete. 

 

Just after switching on, the 

Unico 150

 automatically starts a warm-

up  phase,  and  the  front  panel  LEDs  –  between  the  input  selection 

and  volume  knobs  –  blink.  During this phase the output stages are 

disabled. 

 

The  working  temperature  for  the  tubes  is  reached  less  than  40 

seconds after switching on, but best results will be obtained after at 

least 10 minutes of warm-up.
