Manufacturer's Description for QSC PLX1202 Power Amplifier

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 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 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. 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.

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. zZounds is an authorized dealer of QSC products.
