GXD4

The GXD Class-D amplifiers have been engineered for high performance output and optimized for maximum real-world headroom into 4 Ω and 8 Ω loudspeaker systems. The power levels of the GXD amplifiers are matched to the most popular loudspeakers. GXD 4, per channel – 400 W into 8 Ω, and 600 W into 4 Ω (1600 W peak)

The Class-D amplifier topology is very efficient, making the GXD amplifiers small and light. In addition the Universal Power Supply used in the GXD helps to reduce weight. The GXD amplifier is 2RU and are only 229 mm (9 inches) deep. Weighs in at 5.1 kg (11 lbs).

The GXD amplifiers have an LCD for control and monitoring, with three buttons for menu navigation, and two knobs for adjusting parameters. There are 18 User Presets that can be edited, stored and recalled to match any configuration or system. Each channel has parallel XLR and ¼” TRS connectors for inputs. The outputs are professional NL4 and binding post connectors for mono and bi-amp speaker connectivity.

Power

High peak output power with up to 1600 watts from the GXD 4.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.

Display

E Series Entertainment System DSP Tunings are now available for GXD processing amplifiers: Visit the GXD Firmware Updater to download and update.Large LCD display simplifies amplifier setup and indicates amp status.Front panel LEDs indicate signal presence, input overload, and amplifier clipping.

Protection

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.

Compatibility

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.
