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
Features:
- Power levels matched to the most popular loudspeakers and optimized for the maximum real-world headroom into 4Ohm and 8Ohm loudspeakers
- Class-D output power with a universal switch mode power supply for high performance and efficiency, as well as light weight
- Extensive and powerful loudspeaker processing to maximize loudspeaker performance that includes, Crossover and Parametric EQ filters, Delay, and Power Limiting
- Parallel XLR and 1/4" TRS input connectors for compatibility with any source while providing convenient loop-thru capability
- Professional NL4 and Binding Post output connectors provide mono and bi-amp speaker connectivity
- Detented encoders for precise gain and DSP parameter control
- Front panel LEDs monitor, Power, Signal and Clipping
- Large 256 x 128 LCD display with dual rotary encoders for fast simple set-up and on-screen monitoring of the amplifiers' output levels
- Flexibility to create, store and recall up to 20 user presets for any application
