RCF XPS 4K and XPS 4KD: 4-Channel DSP Amplifiers

RCF XPS 4K High-Performance 4-Channel DSP Power Amplifier

RCF XPS 4K is a professional four-channel power amplifier designed for high-demand installed sound applications requiring precision, reliability, and efficient power delivery. It provides a total output of 4000 W with 4 x 1000 W Class D continuous power at 4 ohms, offering a compact yet powerful solution in a 2U rack format. Engineered for professional audio installations, it ensures consistent performance with low distortion and high efficiency.

The amplifier integrates advanced DSP processing running at 96 kHz with 40-bit floating-point architecture and 32-bit internal routing, enabling highly accurate sound reproduction and system control. RCF proprietary technologies such as FiRPHASE, Bass Motion Control, and Bass Shaper enhance phase alignment, low-frequency control, and overall audio clarity, ensuring optimized performance across all speaker configurations.

Each output channel includes a complete processing chain with EQ filters, FIR filtering, crossover control, multiband compression, RMS limiting, thermal protection, and up to 4000 ms delay adjustment. This allows precise system tuning for a wide range of installed audio environments such as auditoriums, houses of worship, and performance venues.

The XPS 4K features full RDNet network management for remote monitoring, configuration, and control, along with a front-panel 4.3-inch color TFT touchscreen for intuitive setup and real-time adjustments. It supports analog and digital AES/EBU inputs with flexible routing options, making it adaptable to complex audio system designs.

With built-in speaker presets, advanced protection systems, and a highly efficient Class D amplifier design, the XPS 4K ensures stable operation and long-term reliability. Its compact design, low noise operation, and professional-grade processing make it an ideal solution for modern installed sound systems requiring high-quality performance in a space-efficient format.
