The PLX2 series is a range of premium quality, high-power amplifiers designed
for the most demanding live performance uses. Built on the third generation of
QSC PowerLight ® technology, PLX2 amplifiers combine light weight, superlative
audio quality and proven QSC reliability. With power ratings up to 3,600 watts,
PLX2 amplifiers are capable of providing plenty of clean, undistorted output to
the most power hungry speaker systems.
Two ways to get PLX2 performance
The "02" models (PLX1802, PLX2502, PLX3102 and PLX3602) are the right choice for
users who need to drive up to four loudspeakers from each amplifier channel (2
ohm loading), or when extremely high power bridge mono operation is required.
These models feature built-in subwoofer processing, filter switches, and front
panel indications of bridge mono status.
The compact "04" models (PLX1104, PLX1804) bring the same performance and
technology, plus even greater value, to applications that don't require bridged
or 2 ohm operation. Designed to power one or two speakers from each amplifier
channel (4 ohm minimum loading), these models offer a simplified feature set
while retaining genuine, uncompromised PLX performance and technology. Weighing
just 13 pounds (5.9 kg) these "plug-and-play" amplifiers are perfect for
ultra-portable rigs, as well as reference-quality playback.
Mechanical
PLX2 series amplifiers have the refined, rugged good looks usually associated
with high performance racing cars, competition bikes, professional power tools,
and high power machinery. A solid, cast-aluminum front panel adds professional
style to any rack while also acting as an integral I-beam, rigidly tying the
chassis together for years of on-the-road reliability.
Additional mechanical touches such as the side stiffening rails, rear rack ears
and cable tie anchor points attest to QSC's years of experience and attention to
detail. QSC has even designed the integrated front handles so the amplifier
slides into a rack without scraping the installers fingers on the rack sides.
The exterior appearance of PLX2 amplifiers conveys what's inside - simply and
truly, 13 to 21 pounds of the most advanced professional power amp on the
planet.
PowerLight Technology
PowerLight switchmode technology replaces a large, heavy AC transformer
(typically 20 lbs. / 9 kg) with a highly efficient and lighter-weight active
design. Conventional AC transformers provide 100 or 120 energy pulses per
second, the PowerLight supply delivers 190,000 to 230,000 pulses per second.
More pulses make it easier to provide on-demand power for the amplifier's output
section. The power supply doesn't "sag" so bass notes stay full and powerful
while the high end remains crisp and clean.
Audio Quality
PLX2 audio power circuitry achieves performance normally associated with studio
reference amplifiers. In order to reduce crossover distortion, precision bias
tracking makes minute adjustments as amplifier temperature changes. The benefit
is cleaner high-frequency and more consistent sound no matter how hard the
amplifier is driven. The higher power models use QSC-exclusive class H output
circuitry, a form of audio "turbocharging" that increases maximum power without
affecting the basic audio quality.
