DESCRIPTION
 

QSC GDX8 - Light weight, classD professional power amplifier

Features

  • 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.
  • Adjustable speaker protection to match your loudspeaker’s power and impedance.
  • Front panel LEDs indicate signal presence, input overload, and amplifier clipping.
