and convention centers.
The concert stage is
the ultimate test of
professional audio
technology. Concert audio performance has to be impec-
cable. Reliability, unshakable. Effi ciency, un-
beatable. Factory support, unstoppable. For

one of these mission critical dimensions.
Top grossing concert performers are the
most demanding clients in the world.
There’s no room for compromise among
the professionals who provide the techni-
cal foundation that allows those artists to
express their creativity. Time after time, tour
after tour, show after show, these industry
leaders stake their reputations — and their
businesses — on QSC technology, without
second chances or retakes. Night after
night, venue upon venue across the globe,
QSC professional audio systems do exactly
what Pat Quilter and his team of engineers
designed them to do – deliver.
Ultimate Audio Performance
One world class power supply,
two output technologies.
Over four decades of R&D, we’ve learned
to take innovative leaps one at a time.
Since PowerLight™ remains the world’s
most effi cient supply, we developed new
output stages.
PL340 & PL325:
Ultimate Class H Technology
We design for the total show: load-in to
load-out and everything in between. That’s
why the 2-tier linear PL340 and PL325 not
only have ruler-fl at response into 8 ohm
loads, but similar transparency and detail
into 2 ohms.
PL380: Ultimate Class D Technology
Class D amplifi er design offers ultimate
power conversion effi ciency and entails
greater complexity than linear topologies.
It is also harder to master since it has more
signal-conversion stages, each a source of
errors that must be corrected. The PL380
Power, fl exibility, pristine audio quality and legendary
QSC reliability — the ultimate concert amplifi ers.
