OVERVIEW
Designed for professional touring applications.
The QSC PL236 POWERLIGHT 2 Series Power Amplifier was designed exclusively for the touring and live sound professional. Installed with POWERLIGHT technology, the rackmount PL236 amplifier takes your sound to a whole new level. Not only does it give you tighter bass and clean transparent highs, POWERLIGHT also cuts waste heat, boosts reliability and gets rid of unwanted noise and hum. The QSC POWERLIGHT Power Amp 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 through an ultra-low impedance circuit. So unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.
