2400 Watt power amplifier.
Overview
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. PLX offers 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 PLX runs cool and is 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… read more and out of the amplifier. read less

"When compared to the rest... this it the BEST"
you expect it to be good, great even, but you were wrong, it blows your mind !
Sound
As for soundquality this is as good as it gets, I have tested it against LAB, CROWN, MASTER, and it winns in all aspects.
It is fast aggressive and hard, all in the best meening of these words, it is (dare I say) perfect.
It is a precision tool, it does not miss anything, every detail is there, clear, powerful.
I have also tested it against expensive HIFI gear, (Audio Research VS55 as an example), an even race hifi~wise, and it won easily when it came to power and control.
Features
It has all the features you could possibly want.
Quality
It is QSC is it not, no need to comment any further.
Value
for this amount of money... anything else would be a sure sign of stupidity.
Manufacturer Support
Thanks to qsc's technical support forum on their homepage, it is the best i have ever encountered.
The Wow Factor
all the above !
Musical Style:
Drum&Bass, Jazz, Techno , electronica
