More information and specs from QSC.

A line of amplifiers that defines high impact. Up to 3,400 watts in a 2 rack-unit chassis that's only 13 in. deep and 21 lbs. It includes the exclusive PowerWave Technology used in the award-winning PowerLightÈ 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 the PLX series running under the most demanding conditions, the Advanced Thermal Management System has been added. PLXs offer the reliability of a company that's been building professional amplifiers for over 30 years.

With PowerWave technology, the PLX Series takes 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 and ultra-low impedance circuit.

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. The 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.
