QSC PLX3102 Lightweight Power Amplifier
The PLX2 series is a range of premium quality, high-power amplifiers designed for the most demanding live performance uses. Built on the third generation of QSC PowerLight technology, PLX2 amplifiers combine light weight, superlative audio quality and proven QSC reliability.
The PLX3102 is an excellent choice for users who need to drive up to four loudspeakers from each amplifier channel (2 ohm loading), or when extremely high power bridge mono operation is required. The PLX3102 features built-in subwoofer processing, filter switches, and front panel indications of bridge mono status.
