The QSC PLX-1802 is a rackmount stereo power amplifier, offering up 330W per channel at 8 Ohms, and weighing in at a mere 21 pounds. The unit is designed to drive up to 4 loudspeakers from each amplifier channel (2 Ohm loading), or when high power bridge mono operation is required, and offers a comprehensive feature set with uncompromised PLX performance and technology.
The PLX-1802 features built-in subwoofer processing, filter switches, and front panel indications of bridge mono status, and is a worthy solution for either high-quality portable P.A. amplification use, or in a studio situation as a reference playback alternative.
