QSC PLX1202 2U rack mount Power Amp - 2 x 325 W

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(TM) Technology used in our award-winning

PowerLight(TM) 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.

FEATURES

Exclusive PowerWave power supply for superior bass and lighter weight

Ultra-low distortion (0.03% THD at 8 ohms) & studio-quality noise floor (-107 dB)

LED indicators include bridge mono and parallel input modes

Compact 2 RU, 21 lbs. and 13" deep chassis fits into any rack

Class H output reduces AC power draw and heat by 40% (2402, 3002, & 3402)

Selectable clip limiters and subsonic filters reduce distortion and protect speakers

Variable-speed fan for low noise and solid 2 ohm performance

Both 1/4" TRS & XLR inputs, Speakon(TM) and shock-proof binding post outputs

3-year warranty plus optional 3-year extension available
