- 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.
