The PowerLight™ 3 Series is designed for the most demanding live audio

users, whether in touring rigs or fixed installations. The most requested

features of the PowerLight 2 series have been upgraded to deliver

“the ultimate analog amplifier”, while the QSC DataPort ensures full

compatibility with advanced digital processing and QSControl.net™. Three

models range in power from 1250 watts to 4000 watts per channel at

two ohms, all in two-rack space chassis that are only 15.6" (40 cm) deep

and 22 lb (10 kg).

In addition to higher power, the PowerLight 3 Series offers higher input

voltage, selectable sensitivity, and easily adjusted rear panel switches

with color coded LED indicators. For those users who simply want a high

performance amplifier to go with their existing processor or console, the

PowerLight 3 Series is an ideal choice, offering high power, excellent

value, and zero signal latency. When complete integration of amplifier

control, monitoring and DSP is desired, the PowerLight 3 Series is fully

compatible with the QSControl.net™ BASIS™ networked audio platform,

with its comprehensive drag and drop DSP functionality. Simpler DSP

requirements can be met with the DSP-4 processing module.

The flagship of the PowerLight 3 Series is the new 8000 watt PL380.

This highly refined, all-switchmode amplifier incorporates nearly 40 years

of QSC engineering experience, resetting expectations for Class D audio

quality. The PL380 combines a pair of 4000 watt Class D amplifier

channels with the well proven PowerLight supply, to deliver more than

twice as much audio power as previous 2 rack unit PowerLight amplifiers.

Reactive “back EMF” from the speaker is recycled to the power supply,

and unmatched “plug-to-plug” efficiency of 85% keeps AC power needs

to a minimum, while delivering more energy to the speaker.

Years of patient development have resulted in outstanding 20 Hz –

20 kHz audio performance, plus complete protection from normal

hazards of the trade. Even simple features such as dependably silent,

surge-free on-off switching indicate the special care taken to keep things

safely under control. The most pronounced “sonic signature” of the

PL380 is one of immense headroom, sailing through even the most

difficult loads with no signs of stress or change of tonality.

For lower power applications, the PL325 and PL340 offer the same

feature set, matched to upgraded versions of QSC’s most advanced linear

amplifier platform. Recent advances in power supply capacitors further

improve power and low-impedance performance, while continuing to

offer the best available audio performance. As a result, designers have

the choice of running a single type of amplifier throughout their rig, or

matching amplifier performance to specific transducer types.

In keeping with normal QSC design standards, back-to-front airflow

provides up to twice as much long-term average power as most

competitors, without dumping hot air into the rack. All PowerLight 3

models are built in the same chassis size, with common back panel

layouts to facilitate easy racking and hookup.
