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.
