Qsc GXD8

The QSC GXD8 2-channel power amplifier is 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 the GXD8. Add contemporary styling, multiple routing options, light weight, digital signal processing and advanced protection circuitry, and the GXD8 clearly represents real value – something everyone can use. The GXD8 is optimized for use with 8 and 4 ? loudspeaker loads, and delivers just the right amount of power to the most popular speakers used by entertainers and production professionals. The GXD8 also brings 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 GXD8 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 (4 ? and 8 ?), and selecting whether Mild, Medium or Agressive protection is desired.
