The GXD Amplifier Series
QSC's GXD amplifiers boast long-term reliability combined with
professional audio quality. Integral signal processing and an
intuitive design make it easy to achieve incredible sound. Multiple
routing options and versatile DSP are housed securely in a
lightweight, stylish enclosure. With advanced protection circuitry
and QSC's hallmark construction, each GXD amplifier ensures
outstanding performance each and every time you use it.
Each GXD amplifier is designed to deliver the perfect amount of
power to the most popular speakers in the entertainment and
production industries. This powerful series of amplifiers is
optimised for use with both 4 and 8 Ohm speaker loads, whilst
powerful DSP tunings enable you to maximise the performance of QSC
E Series loudspeakers. With flexibility and accessibility on tap,
GXD amplifiers are the perfect solution for any system.
E-Series Entertainment System
Each of QSC's E Series loudspeakers are designed to deliver
incredible sound with any pro-grade power amp. However, if you take
advantage of a complete E Series Entertainment System with a
GXD/PLD power amp or TouchMix digital mixer, you gain access to a
whole new world of performance capabilities and options.
E Series DSP settings have been meticulously designed to maximise
the performance of your E Series loudspeakers, and come pre-loaded
on each GXD amplifier. These tunings support a broad range of
situations, including live sound reinforcement, stage monitoring,
DJ systems, karaoke and more.
Optimised power points
Thanks to a vast amount of research and development, QSC have
created a series of amplifiers that are a perfect fit for the most
popular systems used in a wide range of environments. Designed with
particular power points in mind, GXD amps are ideal for a broad
range of systems.
When an amp produces too little power, your speakers won't perform
to the full-extent of their capabilities. When an amp has too much,
it generally comes at greater expense to you. The GXD 4 (1600W
peak) and GXD 8 (4500W peak) provide the perfect amount of power
for the most popular loudspeakers and PA systems in the
entertainment and production industries - reliable and affordable
power with minimal wastage.
Advanced digital signal processing
Full loudspeaker processing in a convenient and versatile
format. GXD amplifiers feature advanced DSP designed to get the
best out of your system. This powerful series provides you with a
plethora of features and adjustability to get the sound you crave
at a whole new price point.
24dB Linkwitz-Riley HPFs and LPFs, 4-band parametric equalisation,
signal alignment delay, and RMS/Peak limiting. Each amplifier gives
you powerful tools for professional sound and efficient operation.
Twenty handy factory presets provide you with a range of effective
starting points which you can easily modify to suit your needs.
