PL380

Power Amplifier

PowerLight 3 Series is comprised of our “Ultimate Analog” power house amplifier, designed for the most demanding concert and live-sound reinforcement applications. The PL380 features the ground breaking PowerLight™ power supply technology, dramatically reducing weight, eliminating AC mains hum and improving audio quality. Comprehensive remote control and monitoring can also be achieved via the Q-SYS networked platform.

  • Class D topology provides efficient performance at extreme power loads
  • Three-position Input Sensitivity switch ensures gain-matching with existing amp racks and power systems
  • User defeatable clip limiters and selectable low-frequency filters (30 Hz, 50 Hz, Bypass)
  • DataPort connection supports external amplifier control and monitoring via Q-SYS
  • XLR and Block Input connectors and Binding post or Neutrik speakON® Output connectors
  • Comprehensive internal protection protects amplifiers and loudspeakers against over-current, over-temperature and clipping – without compromising program signal

Features

  • PowerLight switch-mode power supply for highest efficiency and improved audio performance
  • Flow-through air path and solid aluminum heat sinks for maximum cooling
  • DataPort supports remote network control and monitoring via Q-SYS
  • Detented gain controls with 1-dB steps for precise calibration
  • Removable knobs with lock-out security plate to prevent unauthorized tampering
  • User defeatable clip limiters and selectable low-frequency filter per channel (3 Hz, 30 Hz, or 50 Hz)
  • Three selectable gain structures (26 dB, 32 dB, or 1.2 V)
  • Front and rear panel LEDs indicate status of switch settings at a glance
  • Parallel XLR/M and XLR/F connectors for simple loop-through connectivity
  • Neutrik Speakon® and "Touch-Proof" binding post outputs
  • Neutrik Powercon® power cable remains secure on the road
  • 3 year warranty, plus optional 3 year extended service contract
  • Linear Class H output circuit offer double the typical efficiency of Class B, reducing AC current consumption and cooling requirements
  • Class D output circuit produces massive output power with even lower losses and minimal increase in average AC power, dramatically reducing power distribution demands compared to older high power amplifiers
