QSC GXD8 | 2-channel Amplifier With Dsp | 800w 8ohms

GXD8

Professional Power Amplifier

• 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
• E Series Entertainment System DSP Tunings are now available for GXD processing amplifiers
• Large LCD display simplifies amplifier setup and indicates amp status
• Inputs: Parallel XLR and 1/4-inch 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
