QSC GXD4, Lightweight, class-D power amplifier with DSP,

Features

QSC GXD4 Light weight class-D professional power amplifier with DSP 2 channels 400 watts/ch at 8ohms  600 watts/ch at 4ohms total power capacity of 1600 watts.

The GXD Series amplifiers are ideal for portable sound reinforcement applications and installations with demanding DSP requirements and flexibility at a cost effective price. This high performance line consists of two amplifiers the GXD4 and GXD8 each providing enormous Class-D power in a lightweight and efficient package. The universal switchmode power supply helps reduce the weight increase efficiency and ensures rock-solid continued operation even with poor power conditions. The addition of on-board DSP processing with an easy-to-use interface offers powerful tools like Crossover and EQ filters Delay and Power Limiting that allow the user to configure the amplifier and maximize the performance of their loudspeakers. The GXD Series amplifiers are engineered to meet any demanding application and provide excellent power and legendary QSC reliability in an efficient lightweight and flexible package; bottom line the GXD amplifiers provide outstanding value!

The GXD amplifiers are unlike other amps in this category that provide little more than a front panel screen to control the same functions that have been under rear-panel DIP switch control for decades. The GXD amps bring full-function loudspeaker processing capability to a new price point with all the processing necessary to get the most from a loudspeaker system. The DSP section includes High and Low-Pass filters (24dB LR) 4-band parametric equalizer signal alignment delay and RMS/Peak speaker protection limiting. Twenty presets for selected typical systems are provided as generic "starting points" are included.

• 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 4ohms and 8ohms 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.
