QSC's GXD 8 power amplifier delivers clean, efficient Class D power to drive your passive PA speakers, with peak power up to an impressive 4500 watts! The "D" in GXD stands for digital: These amps come with powerful, easy-to-use DSP built in, so you can set up and tune your PA system without an outboard loudspeaker processor. With high wattage and smart DSP in an affordable package, QSC GXD 8 power amps help you get more out of your PA speakers.
20 Recallable DSP Presets: Set Up Your PA Fast
There's a reason the GXD 8 amplifier says "Processing Amplifier" on the front panel -- this amp packs extensive DSP tools for setting up your PA system. You have high-pass and low-pass filters, 4-band parametric EQ, delay up to 50 ms, and peak limiting -- all controllable from the front LCD screen. As a starting point, QSC gives you 20 presets for typical systems. You can customize, store and recall the presets to serve just about any application.
On-board DSP: Crossover, Parametric EQ, Delay, and LimitingCrossover:
Feed precise frequency bands to your subs, mids and top boxes without a separate speaker processor. The QSC GXD 8 amp includes 4th-order Linkwitz-Riley 24 dB/octave high-pass filters adjustable from 20 Hz to 4 kHz, low-pass filters adjustable from 60 Hz to 4 kHz, and polarity settings.
Tune your room (and compensate for problem frequencies) with a built-in 4-band…
equalizer, with variable frequency, gain, and bandwidth (Q).
Delay: Time-align systems in large spaces with up to 50 milliseconds of delay.
Peak Limiting: Select the wattage and impedance for each loudspeaker, select Mild, Medium, or Aggressive protection, and let your GXD 8 amp help get the most out of your system safely. QSC's digital limiter prevents the amp from being driven into clipping, protecting your speakers while delivering maximum usable output.
Large LCD and Rotary Encoders for Simple SetupWhether you're tuning your system before every show, or you prefer to "set it and forget it," the QSC GXD 8 power amp makes setting up your PA easy with a large LCD front-panel display. No more using a flashlight to toggle DIP switches on the back of the amp! Detented rotary encoders make it easy to control gain and DSP settings. You have front-panel LEDs for power, signal and clipping, while on-screen level meters give you detailed visual feedback so you can see your amp's limiters working.
Parallel XLR and 1/4" TRS InputsThe GXD 4 amp accommodate your rig with with parallel XLR and 1/4" input jacks on each channel. Want to route the same input signal to a second power amp? Use the GXD's convenient loop-thru capability to send the signal in through one connector and out through the other.
Professional SpeakON and Binding Post OutputsThe GXD 4 amp offers two professional binding post connectors, and two SpeakON NL4 connectors. Plug in a 4-conductor cable with NL4 connector to send both amp channels A and B over a single cable -- a convenient option for bi-amping 2-way speakers. The amplifier's NL4 outputs are also compatible with NL2 connectors, for sending channels A and B over separate cables.
