PL340 & PL325: World-Proven
PowerLight Technology and
Ultimate Class H Performance
Choose Your Technology
Maybe you don’t need the PL380 amplifier’s
8 kW output. Perhaps you prefer the sound
of linear output amplifiers for your high-
frequency drivers. The PowerLight 3 Power
Amplification System offers you two excep-
tional choices — the PL325 and PL340.
Both amplifiers update QSC’s well-tested
Powerlight 2 platform, a unique Class H
technology that eliminates audible artifacts
caused by switching between tiers. Their
highly refined linear circuitry delivers the
cleanest output signal available in a profes-
sional power amplifier.
Our latest PowerLight supply has larger
capacitors and more robust semiconduc-
tors for even higher peak power and energy
storage. As always, PowerLight is designed
for the places you work, tolerating surges
and dips gracefully.
Smooth System Integration
The PowerLight 3 Series is designed as a
complete system for high-power concert
amplification, not just a group of products.
That’s why all PowerLight 3 amplifiers share
a common control, connector and indicator
layout: it simplifies building and/or reconfig-
uring your racks, and keeps your wiring neat
and clean.
You may want to use other amplifiers
alongside the PowerLight 3 Series. That’s
why all three of these amplifiers have both
switchable input sensitivity and zero latency.
Reliable Protection
We take thermal overload as seriously as
you do. PowerLight 3 Series fans speed up
if heat sinks rise above 55° C. Increased
air flow is usually enough even during high
level operation. Limiting begins above 80° C.
Temperatures above 85° C only occur with
fan or vent blockage: the amplifier will mute
to prevent significant internal damage.
Global Regulatory Compliance
If your business is concert sound, you
never know how far the next gig will take
you — or what kind of regulations you’ll find
when you get there. PowerLight 3 Series
amplifiers carry both UL and CE approvals,
and meet world recognized FCC Class A
EMI limits for the PL380 and Class B for the
PL325 and PL340.
To prevent unauthorized adjustment
of input attenuation settings, a
security lockout plate is included
with every PowerLight 3 amplifier.
