RCF XPS-4KD 4-Channel DSP Power Amplifier with Dante - 4000W

The RCF XPS 4KD is a four-channel Class D DSP power amplifier designed for demanding professional installed sound applications. Delivering 4000W of total continuous power, with 4 × 1000W at 4 ohms, it combines high power density with advanced digital processing in a compact 2U chassis.

Dante Networking & Advanced Audio Processing

The XPS 4KD provides 8 Dante digital input channels alongside AES/EBU and analog connectivity, enabling flexible integration into modern networked audio systems. Each output features up to 4000 ms of delay, EQ filters, crossovers, FIR filters, multiband compression, RMS limiting, power limiting, and thermal limiting, while RCF technologies such as FiRPHASE, Bass Shaper, and driver excursion control provide advanced system optimization.

RDNet Management & Professional System Integration

The amplifier provides comprehensive system management through RDNet, Gigabit Ethernet, onboard RCF speaker presets, and a front-panel 4.3-inch color touchscreen. With flexible routing, extensive protection circuitry, exceptional signal-to-noise performance, and Class D modules with SMPS and advanced PFC, the XPS 4KD is well suited to high-performance installed sound systems.
