QSC RMX 2450
RRP $1699

The RMX Series amplifiers give you clean, dynamic power with the legendary QSC sound quality and reliability that pros depend on. The RMX Series deliver unmatched performance at a breakthrough price. And with QSC's free 6 year warranty, the RMX is an even better value.

Muscular Power Plant

The power supply is the heart of an amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The RMX uses a powerful high-current toroidal transformer and ample filter capacitance to ensure generous energy reserves. This makes a critical difference in sound quality, allowing the amp to effortlessly punch out high level transients, even when driving abusive 2 ohm speaker loads.
Superior Performance
RMX amplifiers deliver true studio-quality sound. A full complementary output circuit using the highest-grade linear output devices delivers ultra-low distortion (<0.05% THD) and a ruler-flat frequency response. SMT (Surface Mount Technology) triples small-signal component density, enabling us to pack up to 2400 watts of power in a chassis only 2 rack spaces and less than 16" deep. And unlike other designs, RMX output devices are direct-mounted to the heat sink for optimum thermal coupling and cooling.

Comprehensive Features

The RMX Series is packed full of professional features that increase performance and flexibility:
• The RMX 1850HD provides improved thermal performance that gives you higher continuous power in 2 ohms stereo or 4 ohms bridged applications (a RMX 1850HD exclusive!)
• Independent defeatable clip limiters reduce distortion without sacrificing peak performance.
• Selectable low-frequency filters boost system response, protect speakers and ensure low-end tightness by more precisely matching the amplifier's range to the loudspeakers.
• Barrier strip, XLR and 1/4" balanced inputs plus Speakon and binding post outputs provide easy connections.
• Low-noise variable speed fans with rear-to-front air flow keep amplifiers and racks cool.

QSC RMX 4050 HD
RRP $2999

QSC's RMX 4050HD power amplifier represents the state-of-the-art in professional quality performance at an affordable price. Perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians, and mobile DJs, the RMX 4050HD is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven reliability.
Like its smaller sibling (the RMX 1850HD), the RMX 4050HD is one of two RMX "Heavy Duty" models designed to work as hard into 2 ohm loads as most competing amplifiers will at 4 ohms. With a three-tier, Class H design, the RMX 4050HD is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. The 120 volt versions of the RMX 4050HD accomplish all this with a standard 15 amp plug.
Like all RMX amps, the RMX 4050HD features balanced 1/4" TRS, XLR and barrier strip inputs, binding posts and Neutrik Speakon® outputs, front-mounted gain controls, plus signal and clip LED indicators to monitor performance.

QSC POWERLIGHT Q – PL – 325, 340, 380

PL 325 RRP $2499
PL 340 RRP $3499
PL 380 RRP $4999

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 lbs (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.
