The GXD 4 from QSC is a power amplifier designed for professional PA systems utilizing speakers with 4 and 8 ohm loads and a maximum output of 1600W. The GXD 4 employs a class D output stage with a universal power supply for high performance and efficiency, while keeping the unit lightweight at 11.3 lbs. The integrated DSP section includes High and Low-Pass filters (24dB 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 offered on inputs and outputs, the GXD employs smart speaker protection by providing settings for the loudspeaker's continuous output and impedance (4 ohm or 8 ohm). The GXD 4 ships with a standard IEC power cord.
