With an unequaled reputation for sound quality and reliability, the PowerLight® Series is a range of advanced-technology professional audio amplifiers designed for touring professionals. PowerLights feature QSC's exclusive PowerLight technology for extraordinary audio performance, reliability and reduced weight. Four models offer a range of power from 725 to 3,500 watts per channel, allowing you to choose the right power for your special application.

With PowerLight technology, PowerLight amplifiers take your sound to a whole new level. Not only does it give you tighter bass and clean transparent highs, PowerLight also cuts waste heat and boosts reliability. PowerLight is a revolutionary switching power supply technology that provides ample current to the audio power circuitry by charging the supply rails 230,000 times a second though an ultra-low impedance circuit. So unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.

PowerLight Series amplifiers also boast a set of useful features. Individually selectable clip limiters lower distortion and protect speakers, and a standby mode allows remote AC control.

FEATURES

  • PowerLight switching technology - for improved audio performance
  • High efficiency, Class H linear output circuit lowers AC current consumption and cooling requirements by 40% or more (on selected models)
  • DataPort for remote computer control
  • User defeatable clip limiter reduces distortion, protects speakers
  • Advanced thermal management system for superior cooling
  • Detented gain controls with 2 dB steps for easy resetting
  • Comprehensive LED status arrays
  • Variable speed fan for quiet operation
  • Remote AC power control
  • DC, subsonic audio, and thermal overload protection
  • Neutrik "Combo" (XLR & 1/4") and barrier balanced input connectors
  • 3 year warranty plus optional 3 year extended service contract
