Professional 1600 Watt Peak 2-Channel Power Amplifier with DSP

The GXD4 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 GXD4 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 GXD4 ships with a standard IEC power cord.

  • High peak output power with up to 1600 watts from the GXD 4 and a whopping 4500 Watts from the GXD 8.
  • Power levels matched to the most popular loudspeakers and optimized for maximum real-world headroom into 4Ω and 8Ω speaker systems.
  • Class D output stage with a universal power supply for high performance and efficiency.
  • Extensive and powerful loudspeaker processing built in. Includes high and low-pass filters, 4-band parameteric EQ, limiting, and delay.
  • Large LCD display simplifies amplifier setup and indicates amp status.
  • Inputs: Parallel XLR and 1/4" TRS connectors for compatibility with any source while providing convenient loop-thru capability.
  • Precision rotary encoders for gain and DSP parameter control.
  • Outputs: Professional binding post and NL4 connectors (compatible with NL2) provide for mono and bi-amp speaker connections.
  • Digital limiting automatically protects the amplifier from damage due to temperature rise or overdrive.
