QSC PLX-2402

The QSC PLX-2402 comes from a line of amplifiers that defines high impact. It delivers up to 3,400 watts in a two rack-unit chassis that’s only 13 inches deep and 21 lbs.

PowerWave technology delivers 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 running under the most demanding conditions, QSC has added their Advanced Thermal Management System. The PLX offers the reliability of a company that’s been building professional amplifiers for over 30 years.
