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 PLX1802 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 PLX1802 features built-in subwoofer processing, filter switches, and front panel indications of bridge mono status.

• Two Speakon NL4 output connectors provide positive-locking speaker connections. Upper connector provides both channel outputs on all four poles (Channel 1: 1+, 1-; channel 2: 2+, 2-) for bridged mono or for single-cable connection to bi-amplified speakers.
• 21-position front-panel gain controls for precise, repeatable amplifier adjustment.
• Balanced XLR inputs with parallel TRS connectors accommodate all common input connectors and support loop-through operation.
• Patented PowerLight power supply technology with other patents pending.
• Speakon NL4 and binding post outputs.
• 100 Hz high pass and low pass filters for bi-amping subwoofer and satellite systems without the need for an external crossover.
• Switchable/defeatable 33 Hz infrasonic filters protect woofers from overexcursion damage.
• Switchable/defeatable clip limiters.
• Four models with power ratings up to 1800 watts per channel @ 2 ohms, 3600 watts bridged @ 4 ohms
