The QSC GXD8 Professional Power Amplifier with DSP is a designed for professional PA systems utilizing speakers with 4 and 8 ohm loads and a maximum output of 4500W. The GDX 8 employs a class D output stage with a universal power supply for high performance and efficiency, while keeping the unit lightweight at 13.2 lbs. The integrated DSP section includes High and Low-Pass filters (24 dB LR), 4-band parametric equalizer, signal alignment delay, and RMS/Peak speaker protection limiting. The parallel XLR and 1/4" TRS input connectors offer broad compatibility with convenient loop-through capabilities, while the professional binding posts and NL4 connector provide mono and bi-amped speaker connections. In addition to the limiting offers on the inputs and outputs, the GDX employs smart speaker protection by providing settings for the loudspeaker's continuous output and impedance (4 ohm or 8 ohm). The GDX 8 ships with a standard IEC power cord.
