QSC GX Amps- Mid-weight, Heavy power & Light price!
GX Series amplifiers are ideal for professional entertainers who require
maximum performance and portability on a limited budget. The hallmarks
of the QSC brand - professional audio quality, meticulous engineering,
precision manufacturing and long-term reliability - are all intrinsic to
GX. Add contemporary styling, multiple input/output options, light
weight, and advanced protection circuitry, and the GX Series clearly
represents real value - something everyone can use.
GX amplifiers deliver just the right amount of power to the most popular
speakers used by entertainers. Typically, loudspeaker manufacturers
recommend an amplifier with power output equal to the speaker's Program (Music) Power rating or two times (2 x) the Continuous (RMS) Power rating.
The GX3 is ideal for speakers in the 300 watt (Program) range, while the
GX5 provides full performance for 500 watt (Program) speakers. The GX7
outputs 725 watts into an 8 ohm load. Owners of popular 4 ohm
loudspeakers (such as dual-woofer, two-way models) will find the 700
watt (4 ohm) power of the GX5 an ideal match while the GX7's 1000 watts
will very capably power many of today's popular subwoofers or two
typical 8 ohm speakers per channel.
The GX7 adds the road-proven PowerLight supply to the Class H output
section, for more overall output power and additional weight savings.
The result is one of the highest power-to-weight ratios in the industry.
A low-noise variable-speed fan with rear-to-front airflow keeps
amplifiers and racks cool.
As always, GX Series amplifiers are fully protected
from the usual hazards of the trade, ensuring stable performance and
long life.
GuardRail™
GuardRail protection delivers full peak power while
preventing detrimental overloads. During excessive clipping, or extreme
overheating, GuardRail reduces gain just enough to preserve the
integrity of the music, protect the speakers and keep the audience
excited, without unprofessional distortion levels or shutdowns.
Subwoofer/Satellite Crossover
A subwoofer reduces strain on the full-range
speaker, allowing it to play louder, or letting a smaller speaker do the
same job. The GX Series supports this mode with a Crossover switch that
splits the full-range input entering Ch 1, sending 20 Hz -100 Hz to the
sub (Ch 1) and 100 Hz - 20 kHz to the top box (Ch 2). The front panel
gain controls balance the sub and top box, while GuardRail optimizes
peak power into the sub and top individually, for greater musical impact
and dynamic range. GuardRail optimizes peak power into the sub and top
individually, for greater musical impact and dynamic range.
