Follow the instructions below to connect Your sound system correctly.

 

 

STEP 1 / HOOK-UP OF THE SPEAKERS 

 
Check the impedance of the speaker set that you posses. Connect the speaker cable to the 
appropriate terminals on the rear panel of the amplifier. Depending on the impedance of the 
speakers  that  you  posses,  connect  it  to  the  terminal  marked  either  4  Ω  or  8  Ω.  If  your 
speaker impedance is 6 Ω - connect the speaker wire to the terminal 8 Ω. 
 
 

STEP 2 / HOOK-UP OF THE SIGNAL SOURCES 

 
Connect the signal source to the amplifier inputs IN1, IN2 or IN3. Select the source of input 
signal by rotating the input selector located on the front panel of the amplifier. In order to 
achieve  the  highest  sound  quality,  use  only  high-quality  RCA  cables.  Pay  attention  to  the 
proper  connection  and  distinction  of  the  right  (R)  and  the  left  (L)  channels.  For  the  best 
sound quality, we suggest using the Fezz FAC 01 interconnect cable dedicated for Fezz Audio 
vacuum tube amplifiers. 

 

 

 

 
 

STEP 3 / HOOK-UP OF THE POWER SUPPLY CORD 

 
Make  sure  that the  amplifier  is  switched off.  Connect  the  power  cord  to  the  IEC  socket on 
the rear panel of the amplifier. 
The amplifier is designed to operate at a rated voltage of 230V / 50Hz. Connecting the device 
to  a  mains  network  with  incorrect  parameters  can  lead  to  damage  that  is  not  covered  by 
manufacturers warranty. 
 
 

FIRST POWER-UP AND GETTING STARTED______________________ 

 
Make  sure  that  all  of  your  wiring  is  connected  in  accordance  with  the  information  as 
provided above on page 9 of this manual. 
Select the source of signal using the rotary selector switch located on the front panel. Set the 
volume  control  to  minimum.  Turn  on  the  mains  power  of  the  Alfa  Lupi  amplifier  –  the 
vacuum  tubes  shall  begin  to  glow.  Make  sure  that  the  sound  source  is  turned  on,  playing, 
and then gradually increase the volume level by turning the potentiometer. 
 
The  operation  of  the  amplifier  narrows  down  to  adjusting  the  volume  via  VOLUME 
potentiometer and selecting an audio signal source via rotation of the SOURCE switch. 
 

 

To connect a turntable, You will need to use an external phono MC/MM 
preamplifier or turnatble with a built-in preamplifier.
