QSC PL236 Product Information

QSC PowerLite PL236 Dual channel amplifier 2x1100W @4ohms

The PowerLight 2 Series is a high performance line of amplifiers designed exclusively for the touring

and live sound professional. Four models range in power from 900 watts to 1850 watts per channel, all

in two-rack space chassis that are only 14" deep and 21 lbs.

Each of these models are available in two versions: a Base model and an "A" version. Base models are

ideal for systems using external signal processing. For those looking for integrated solutions, "A"

versions offer internal analog signal processing. Full DSP capabilities may also be added to any model

with the addition of the DSP-3 Module.

With PowerWaveTM technology, PowerLight 2 amplifiers take your sound to a whole new level. Not only

does it give you tighter bass and clean transparent highs, PowerWaveTM also cuts waste heat, boosts

reliability and gets rid of unwanted noise and hum. PowerWave 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.

Through continued improvement and innovation, QSC’s new PowerLight 2 offer features not found in any

other professional audio amplifier.
