The PLX Series

PLX3402 Amplifier
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 PowerLight® Technology used in our award-winning PowerLight Series for chest-pounding bass and crystal-clear highs. It also features hum-free noise floor and ultra-low distortion of 0.03% 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.

PLX Series amplifiers are no longer being manufactured, please see the PLX2 Series Amplifiers for equivalent replacements.
