เครื่องขยายเสียง QSC PLX1804 600 W 8 Ohm

The QSC PLX1804 is a lightweight rackmount stereo power amplifier, offering up 600 Watts per side at 8 Ohms and weighing in at a mere 13 pounds. The unit is designed to power 1 or 2 speakers from each amplifier channel (4 ohm minimum loading) and offers a simplified feature set while retaining uncompromised PLX performance and technology.

The PLX1804 is a worthy solution for either high-quality portable P.A. amplification use, or in a studio situation as a reference playback alternative.


  • Lightweight, high-output stereo rackmount power amplifier
  • 21-position front-panel gain controls for precise, repeatable amplifier adjustment
  • Cooling design with front-exit hot air exhaust, flow-through heat sinks require no filters, eliminating clogging
  • Full short circuit, open circuit, thermal, infrasonic, ultrasonic, and RF protection, stable into reactive or mismatched loads
  • Clip limiting protects speakers; thermal limiting maintains operation even during abnormal overload conditions
  • Front panel LED power, clip, -10 dB, and signal present indicators for system monitoring and troubleshooting
  • Balanced XLR inputs with parallel TRS connectors and loop-through support
  • Speakon NL-4 output connectors with positive-locking speaker connection; Ch. 1 output uses all 4 wires for single-cable connection to bi-amplified speakers
