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 is 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 PowerLight ® technology, PowerLight 2 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, boosts reliability and
gets rid of unwanted noise and hum. 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
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.
