With  an  unequaled  reputation  for  sound  quality 
and  reliability,  the  PowerLight

®

  Series  is  a  range 

of  advanced-technology  professional  audio  amplifiers 
designed  for  touring  professionals.  PowerLights 
feature  QSC’s  exclusive  PowerLight  technology 
for  extraordinary  audio  performance,  reliability 
and reduced weight. Four models offer a range of power 
from 725 to 3,500 watts per channel, allowing you to 
choose the right power for your special application.

With PowerLight technology, PowerLight amplifiers take 
your  sound  to  a  whole  new  level.    Not  only  does  it 
give  you  tighter  bass  and  clean  transparent  highs, 
PowerLight  also  cuts  waste  heat  and  boosts  reliability. 
PowerLight  is  a  revolutionary  switching  power  supply 
technology  that  provides  ample  current  to  the  audio 
power  circuitry  by  charging  the  supply  rails  230,000 
times a second though an ultra-low impedance circuit. 
So unlike amplifiers that use conventional supplies, the 
audio signal is never starved prematurely and remains 
crisp and clean.

PowerLight Series amplifiers also boast a set of useful 
features.  Individually  selectable  clip  limiters  lower 
distortion  and  protect  speakers,  and  a  standby  mode 
allows remote AC control.
