PowerLight 3 Series
The PL3 Series includes the Class D PL380 as well as two Class H models.
All share a common control, connector and indicator layout for neat and
simplified integration into equipment racks.
Ultimate Real-World Headroom
If you've been up on the riser ringing
out drum monitors, or out at FOH
aligning the subs with the mains, you
know that headroom is not measured
by instantaneous peak power ratings.
It's the ability of the entire amplifier,
from power supply to output devices,
to produce high voltages and currents
for extended periods of time. PL3
Series amplifiers go head-to-head with
products claiming much higher output.
Ultimate System Compatibility
Zero Signal Latency
Of course the PL3 Series has DSP
options. But none of them impose a
latency penalty inside the amplifier.
There's no other way to ensure
compatibility with other amplifiers; no
other way to avoid compromising signal
alignment in multi-way sound systems.
Flexible System Architecture
Choices: they're what the PL3 Series
is all about. Upgrade analog racks and
monitor them on stage. Go all the way
to fully networked digital signal distribution
and processing with remote system
management. Combine elements
of both approaches. It's your decision,
as it should be.
Ultimate Ruggedness
The real art of amplifier design is delivering ultimate power output while protecting the entire system. Like all QSC designs, PL3 Series amplifiers had to pass every one of our electrical and mechanical stress tests – so tough, we've never found another amplifier brand that has survived the full test cycle.

PL380: Ultimate Class D Performance and World-Proven PowerLight Technology
Whatever you expect from switchmode
amplifiers, you'll get more from Pat
Quilter's ultimate Class D amplifier.
More audio quality. More high-end
transparency. More efficiency.
Maximum Energy, Minimal Footprint
The PL380 more than doubles the
power of previous 2RU PowerLight amplifiers,
yet draws only modest amounts
of AC power. Even at full power, the
PL380 converts up to 85% of input
power into speaker-moving, air-moving
and audience-exciting output. That's
about twice the effi ciency of typical
switching amplifiers. This amplifier actually
recycles "back EMF" energy from
the loudspeakers.
Real World Headroom
Audition the PL380 head-to-head with
any high power Class D amplifier on
the planet. We believe the PL380 has
the highest overall efficiency, from AC
plug to speaker terminal, of any amplifier
available. Peak output can reach
185V, and long-term average power is
about twice that of "typical" high power
Class D designs. The PL380 won't lose
efficiency when driving reactive loads.
That's important in the real world of
concert sound.

Unrivalled Audio Performance
From the ultra-fast modulator (its response time is measured in nanoseconds) to the high performance output filters, the PL380 has been designed to sound neutral, accurate and linear. Full-range distortion is exceptionally low, and free from "zero-crossing" distortion.
Simply Efficient Amplifier Topology
Each channel uses a pair of large-die FETs in a package normally used for motor drives and other extreme applications. This system is simple and reliable, with far more safety margin than normal audio devices.
Massive Where It Counts
The PL380's immense electrical power is carried on a four-layer PCB with 3 ounce copper. Pat Quilter and his team patiently refined grounding and shielding to keep switching noise out of the sensitive audio circuitry.
