Specifications for your new

V-12R

 

power amplifier.

We have updated the V-12 mono and  stereo  models  to  a  RACING  (R)

 

version!  The

new 

racing

  input  circuit  makes  the  input  sensitivity  1.2  volts,  similar  to  most

components currently available. Operating the power amplifier is a simple  procedure.
Each unit is designed for long term stability  in  virtually  any home  operating  situation.
Please  note,  if  the  unit  is  operated  outside  the  parameters  outlined  in  this  owner's
manual, damage may result.  Please read this manual carefully before putting your new
V-12R  in  operation.  The  following  definitions  are  applicable.  Warnings  should  be
followed explicitly.
