Product Description

Details

With PowerLight switch mode power supply, 1250 watts per channel into 4 ohms and class H topology, the PL340 is ideal for live sound / production applications.
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
  • PL340 and PL325
    Linear Class H output circuit offer double the typical efficiency of Class B, reducing AC current consumption and cooling requirements
  • PL380
    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
