QSC GXD4 2 Channel Power Amplifier 600 Watt/4 Ohms with DSP

The GXD Series amplifiers bring professional-grade signal processing to entertainment and production applications at a price point that makes advanced loudspeaker management accessible to working musicians and DJs. These Class-D amplifiers combine QSC’s renowned audio quality and reliability with contemporary styling, multiple routing options, and comprehensive digital signal processing capabilities that include high and low-pass filters, 4-band parametric EQ, signal alignment delay, and intelligent RMS/Peak speaker protection limiting.

Engineered specifically for 8 and 4 ohm loudspeaker loads, the GXD series addresses the real-world needs of sound reinforcement professionals by providing power levels matched to the most popular speakers in the market. QSC’s research into widely-used loudspeakers revealed that most systems utilise woofers with continuous power capacities of 150-250 watts for low-power applications and 250-400 watts for mid to high-power requirements, with the GXD amplifiers designed to provide approximately twice the loudspeaker’s rated capacity for optimal performance without the risk of destructive clipping.

The amplifiers feature extensive connectivity options including parallel XLR and 1/4" TRS inputs with loop-through capability, professional binding post and NL4 outputs compatible with NL2 connectors for both mono and bi-amp configurations. A large LCD display and precision rotary encoders simplify setup and parameter control, while front panel LEDs provide clear indication of signal presence, input overload, and amplifier clipping status. With up to 1600 watts of peak output power and smart speaker protection that can be adjusted for mild, medium, or aggressive limiting based on your loudspeaker’s specifications, the GXD Series represents genuine value for professionals who demand both performance and reliability.
