PROFESSIONAL POWER AMPLIFIERS
A line of amplifiers that defines high impact. Up to
3,400 watts in a 2 rack-unit chassis that’s only 13” deep
and 21 lbs. We included our exclusive PowerWave
Te ch nology used in our award-winning PowerLight™
Series for chest-pounding bass and crystal-clear highs.
It also features hum-free noise floor and ultra-low
distortion of .03% THD. To keep PLX running under the
most demanding conditions, we’ve even added our
Advanced Thermal Management System. PLXs offer
the reliability of a company that’s been building
professional amplifiers for over 30 years.

With PowerWave technology,the PLX series take your
music to a whole new level. Not only does it deliver bigger bass and cleaner highs,
PowerWave also cuts wasted heat and boosts reliability. PowerWave is a switching
power supply that provides ample current to the audio power circuitry by
charging the supply rails 230,000 times a second through an ultra-low impedance
circuit. So unlike other amps with conventional supplies, the audio signal is never
starved prematurely and remains crisp and clean. It virtually eliminates hum and
greatly reduces noise, providing a vast dynamic range that can handle any music
without running out of headroom.
Our Advanced Thermal Management system ensures PLXs
run cool and reliable even under harsh conditions.Using a high-
output variable speed fan,
ATM pulls cool air from the rear of
the amp and propels it through a heat
shroud precision-fitted to flow air over the
heat sinks and out of the amplifier.
