Product Description:

GXD Series amplifiers are ideal for entertainment and production applications requiring performance and the convenience of integral signal processing. The hallmarks of the QSC brand – professional audio quality, engineering and manufacturing focused on long-term reliability - are all intrinsic to GXD. Add contemporary styling, multiple routing options, light weight, digital signal processing and advanced protection circuitry, and the GXD Series clearly represents real value – something everyone can use.
The GXD series is optimized for use with 8 and 4 ohm loudspeaker loads. GXD amplifiers deliver just the right amount of power to the most popular speakers used by entertainers and production professionals.
The GXD amplifiers are unlike other amps in this category that provide little more than a front panel screen to control the same functions that have been under rear-panel, DIP switch control for decades. The GXD amps bring full-function loudspeaker processing capability to a new price point with all the processing necessary to get the most from a loudspeaker system. The DSP section includes High and Low-Pass filters (24dB LR), 4-band parametric equalizer, signal alignment delay, and RMS/Peak speaker protection limiting. Twenty presets for selected typical systems are provided as generic “starting points” are included.
The most common cause of loudspeaker failure is amplifier clipping. The digital limiter used in the GXD amplifiers is set to prevent the amplifier from being driven into clipping while delivering the maximum usable output. In addition to amplifier limiting it also provides smart speaker protection by simply setting the loudspeaker’s continuous power and impedance (4Ω and 8Ω), and selecting whether Mild, Medium or Agressive protection is desired.
Product Features
High peak output power with up to 1600 Watts from the GXD 4 and a whopping 4500 Watts from the GXD 8
Power levels matched to the most popular loudspeakers and optimized for maximum real-world headroom into 4Ω and 8Ω speaker systems
Class-D output stage with a universal power supply for high performance and efficiency
Extensive and powerful loudspeaker processing built in. Includes High & Low-Pass filters, 4-band PEQ, Limiting, and Delay
Large LCD display simplifies amplifier setup and indicates amp status
Inputs: Parallel XLR and 1/4” TRS connectors for compatibility with any source while providing convenient loop-thru capability
Precision rotary encoders for gain and DSP parameter control
Outputs: Professional binding post and NL4 connectors (compatible with NL2) provide for mono and bi-amp speaker connections
Digital Limiting automatically protects the amplifier from damage due to temperature rise or overdrive
Adjustable speaker protection to match your loudspeaker’s power and impedance
Front panel LEDs indicate signal presence, input overload, and amplifier clipping
