QSC PLX 1802 Power Amp - 2 x 575W @ 4ohms
Designed to drive up to four loudspeakers from each amplifier channel (2 ohm loading), or when extremely high power bridge mono operation is required, the QSC PLX 1802 delivers up to 1800 W of power and features built-in subwoofer processing, filter switches, and front panel indications of bridge mono status.
Boasting third generation QSC PowerLight technology delivering 100,000 energy pulses per second (compared to 60 pulses per second from conventional AC transformers), its power supply doesn't "sag" so bass notes stay full and powerful while the high end remains crisp and clean.
To reduce crossover distortion, its precision bias tracking makes minute adjustments as the amplifier temperature changes. This makes for cleaner high frequency and more consistent sound no matter how hard the amplifier is driven.
Weighing only 21 lbs (9.5 kg), the compact yet rugged PLX1802 will give you professional grade performance without breaking your back—or your budget.
QSC PLX1802 Features
- Very light weigh: 21 lb/9.5 kg
- Cooling design exhausts hot air out the front, keeping the rack cool. Flow-through heat sinks require no filters that could become clogged.
- Front panel LED power, clip, -10 dB, and signal present indicators for system monitoring and troubleshooting.
- 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
- Switchable/defeatable 33 Hz infrasonic filters protect woofers from overexcursion damage.
- Switchable/defeatable clip limiters.
