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
