The GXD packs a lot of punch with its DSP processing and whopping 1600W. Use it to power your church PA, club PA, restuarant, bar, shopping mall - the list just goes on!

• High peak output power with up to 1600 Watts
• 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 & Low-Pass filters, 4-band PEQ, 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
