This listing is for an amplifier that was recently returned by a customer who did not properly spec his power needs. As you can see from the pictures, this amplifier is still in fantastic condition (this is the actual unit you would be receiving - Serial Number: GAF0M0284)! All original cables and paperwork are included as well, but unfortunately this customer no longer had the original box. Otherwise, it's just like NEW! Thanks for looking! | | | | MINT CONDITION QSC GXD8This item is a very lightly used item that is in mint condition and has been tested to original specifications and is in perfect working condition!Professional Power AmplifierRetail Price: $999.99Includes:

| | | 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 Right PowerThere's a GXD amplifier within 1dB of the ideal power for your speaker system.
Best practice is to use an amplifier capable of delivering approximately twice the loudspeaker's rated power capacity. Too little amplifier and the speakers won't deliver everything they're capable of and the risk of destructive amplifier clipping is increased. Too much power probably means unnecessary amplifier expense.
To determine the power points for the GXD series, QSC examined the loudspeakers most widely used for sound reinforcement by musicians, DJs and production professionals. Overall, these speakers are equipped with woofers that fall into a couple of categories of continuous power capacity - low-power drivers that can handle 150 - 250 watts, and mid to high-power drivers rated around 250-400 watts. Single woofer loudspeaker systems using these drivers will typically have an impedance of 8Ohms. Dual woofer loudspeakers will, of course, have power ratings that are two times that of the single woofer model and an impedance that is half that of single-woofer models.Digital Signal ProcessingThe 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.
Digital LimitingThe 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 (4Ohms and 8Ohms), and selecting whether Mild, Medium or Agressive protection is desired.The GXD 8 Amplifier features a peak output power up to 4500 Watts. | | | Features: | Specifications: | | High peak output power with up to a whopping 4500 Watts from the GXD 8.Power levels matched to the most popular loudspeakers and optimized for maximum real-world headroom into 4Ohms and 8Ohms speaker systems.Class-D output stage with a universal power supply for high performance and efficiency.Extensive and powerful loudspeaker processing built in.
