The Plus Audio AC420D is a four-channel network DSP power amplifier, delivering up to 3350W per channel at 4Ω or 9000W in bridged mode. Designed for professional sound reinforcement, it provides reliable, high-performance operation across both touring and fixed installation environments.
Built on a 96 kHz / 24-bit DSP platform, the AC420D offers advanced signal processing for precise system optimisation. Its onboard DSP includes FIR filters, parametric EQ, and accurate limiting, all accessible via the integrated 4.3-inch IPS touchscreen or through network-based control.
With support for AES/EBU, analogue, and Dante™ inputs, along with operation in both low-impedance (2Ω–8Ω) and constant-voltage (70V / 100V) configurations, the AC420D delivers exceptional system flexibility. Balanced XLR inputs and speakON outputs ensure secure, professional connectivity.
Control and monitoring are managed through Mconsole software, providing an intuitive interface for configuration, real-time monitoring, and scene management. Users can store and recall presets across multiple devices, simplifying setup and control in complex systems.
Comprehensive protection circuits, including short-circuit, DC, and over/under-voltage safeguards, combined with a universal 100–240V power supply, ensure consistent and dependable performance in demanding audio applications.
